  • Oracle Fusion Applications User Experience Design Patterns: Feeling the Love after Launch

    - by mvaughan
    By Misha Vaughan, Oracle Applications User ExperienceIn the first video by the Oracle Applications User Experience team on the Oracle Partner Network, Vice President Jeremy Ashley said that Oracle is looking to expand the ecosystem of support for Oracle’s applications customers as they begin to assess their investment and adoption of Oracle Fusion Applications. Oracle has made a massive investment to maintain the benefits of the Fusion Applications User Experience. This summer, the Applications User Experience team released the Oracle Fusion Applications user experience design patterns.Design patterns help create consistent experiences across devices.The launch has been very well received:Angelo Santagata, Senior Principal Technologist and Fusion Middleware evangelist for Oracle,  wrote this to the system integrator community: “The web site is the result of many years of Oracle R&D into user interface design for Fusion Applications and features a really cool web app which allows you to visualise the UI components in action.”  Grant Ronald, Director of Product Management, Application Development Framework (ADF) said: “It’s a science I don't understand, but now I don't have to ... Now you can learn from the UX experience of Fusion Applications.”Frank Nimphius, Senior Principal Product Manager, Oracle (ADF) wrote about the launch of the design patterns for the ADF Code Corner, and Jürgen Kress, Senior Manager EMEA Alliances & Channels for Fusion MiddleWare and Service Oriented Architecture, (SOA), shared the news with his Partner Community. Oracle Twitter followers also helped spread the message about the design patterns launch: ?@bex – Brian Huff, founder and Chief Software Architect for Bezzotech, and Oracle ACE Director:“Nifty! The Oracle Fusion UX team just released new ADF design patterns.”@maiko_rocha, Maiko Rocha, Oracle Consulting Solutions Architect and Oracle FMW engineer: “Haven't seen any other vendor offer such comprehensive UX Design Patterns catalog for free!”@zirous_chad, Chad Thompson, Senior Solutions Architect for Zirous, Inc. and ADF Developer:Wow - @ultan and company did a great job with the Fusion UX PatternsWhat is a user experience design pattern?A user experience design pattern is a re-usable, usability tested functional blueprint for a particular user experience.  Some examples are guided processes, shopping carts, and search and search results.  Ultan O’Broin discusses the top design patterns every developer should know.The patterns that were just released are based on thousands of hours of end-user field studies, state-of-the-art user interface assessments, and usability testing.  To be clear, these are functional design patterns, not technical design patterns that developers may be used to working with.  Because we know there is a gap, we are putting together some training that will help close that gap.Who should care?This is an offering targeted primarily at Application Development Framework (ADF) developers. If you are faced with the following questions regarding Fusion Applications, you will want to know and learn more:•    How do I build something that looks like Fusion Applications?•    How do I build a next-generation application?•    How do I extend a Fusion Application and maintain the user experience?•    I don’t want to re-invent the wheel on the user interface, so where do I start?•    I need to build something that will eventually co-exist with Fusion Applications. How do I do that?These questions are relevant to partners with an ADF competency, individual practitioners, or small consultancies with an ADF specialization, and customers who are trying to shift their IT staff over to supporting Fusion Applications.Where you can find out more?OnlineOur Fusion User Experience design patterns maven is Ultan O’Broin.

  • Delving into design patterns, and what that means for the Oracle user experience

    - by Kathy.Miedema
    By Kathy Miedema, Oracle Applications User Experience George Hackman, Senior Director, Applications User Experiences The Oracle Applications User Experience team has some exciting things happening around Fusion Applications design patterns. Because we’re hoping to have some new offerings soon (stay tuned with VoX to see what’s in the pipeline around Fusion Applications design patterns), now is a good time to talk more about what design patterns can do for the individual user as well as the entire company. George Hackman, Senior Director of Operations User Experience, says the first thing to note is that user experience is not just about the user interface. It’s about understanding how people do things, observing them, and then finding the patterns that emerge. The Applications UX team develops those patterns and then builds them into Oracle applications. What emerges, Hackman says, is a consistent, efficient user experience that promotes a productive workplace. Creating design patterns What is a design pattern in the context of enterprise software? “Every day, people use technology to get things done,” Hackman says. “They navigate a virtual world that reaches from enterprise to consumer apps, and from desktop to mobile. This virtual world is constantly under construction. New areas are being developed and old areas are being redone. As this world is being built and remodeled, efficient pathways and practices emerge. “Oracle's user experience team watches users navigate this world. We measure their productivity and ask them about their satisfaction. We take the most efficient, most productive pathways from the enterprise and consumer world and turn them into Oracle's user experience patterns.” Hackman describes the process as combining all of the best practices from every part of a user’s world. Members of the user experience team observe, analyze, design, prototype, and measure each work task to find the best possible pattern for a particular work flow. As the team builds the patterns, “we make sure they are fully buildable using Oracle technology,” Hackman said. “So customers know they can use these patterns. There’s no need to make something up from scratch, not knowing whether you can even build it.” Hackman says that creating something on a computer is a good example of a user experience pattern. “People are creating things all the time,” he says. “On the consumer side, they are creating documents. On the enterprise side, they are creating expense reports. On a mobile phone, they are creating contacts. They are using different apps like iPhone or Facebook or Gmail or Oracle software, all doing this creation process.” The Applications UX team starts their process by observing how people might create something. “We observe people creating things. We see the patterns, we analyze and document, then we apply them to our products. It might be different from phone to web browser, but we have these design patterns that create a consistent experience across platforms, and across products, too. The result for customers Oracle constantly improves its part of the virtual world, Hackman said. New products are created and existing products are upgraded. Because Oracle builds user experience design patterns, Oracle's virtual world becomes both more powerful and more familiar at the same time. Because of design patterns, users can navigate with ease as they embrace the latest technology – because it behaves the way they expect it to. This means less training and faster adoption for individual users, and more productivity for the business as a whole. Hackman said Oracle gives customers and partners access to design patterns so that they can build in the virtual world using the same best practices. Customers and partners can extend applications with a user experience that is comfortable and familiar to their users. For businesses that are integrating different Oracle applications, design patterns are key. The user experience created in E-Business Suite should be similar to the user experience in Fusion Applications, Hackman said. If a user is transitioning from one application to the other, it shouldn’t be difficult for them to do their work. With design patterns, it isn’t. “Oracle user experience patterns are the building blocks for the virtual world that ensure productivity, consistency and user satisfaction,” Hackman said. “They are built for the enterprise, but incorporate the best practices from across the virtual world. They empower productivity and facilitate social interaction. When you build with patterns, you get all the end-user benefits of less training / retraining from the finished product. You also get faster / cheaper development.” What’s coming? You can already access design patterns to help you build Dashboards with OBIEE here. And we promised you at the beginning that we had something in the pipeline on Fusion Applications design patterns. Look for the announcement about when they are available here on VoX.

  • Silverlight 4 with WCF RIA architecture applying DDD

    - by doteneter
    Hello, In my ASP.NET MVC applications I use DDD and it works very well. I'm new to Silverlight development and would like to know how could I apply DDD to build a new architecture. I had a look on WCF RIA Services and what is exposed by default it's the simple CRUD methods. I would like to use MVVM pattern. I thought about general architecture and don't know if what I'm thinking about make sense in Silverlight development. I thought about creating Domain Model on the top of SVC. I would than expose by WCF RIA some operation that deals with aggreates in my Domain Model instead of simple CRUD. What I would aloso expose is the ViewModel entieties that could be used by the view. I don't know if it's make sense, if I'm going in a good direction or if applying DDD in Silverlight 4 development is a good practice. I didn't find much informations on Internet. I'll appreciate if you could point me to some interesting links or if you can give me some hints. Thanks for your help.

  • Db4o Mvc Application Architecture

    - by Mac
    I am currently testing out Db4o for an asp.net MVC 2 application idea but there are a few things I'm not quite sure on the best way to proceed. I want my application to use guessable routes rather than Id's for referencing my entities but I also think I need Id's of some sort for update scenarios. so for example I want /country/usa instead of /country/1 I may want to change the key name though (not perhaps on a country but on other entities) so am thinking I need an Id to use as the reference to retrieve the object prior to updating it's fields. From other comments it seems like the UUID is a bit long to be using and would prefer to use my own id's anyway for clean separation of concerns. Looking at both the KandaAlpha project I wasn't too keen on some aspects of the design and prefer something more along the lines of S#arp architecture where they use things like the [domainsignature] and EntityWithTypedId, IEntityDuplicateChecker, IHasAssignedId, BaseObject and IValidatable in their entities to control insert/update behaviour which seems cleaner and more extensible, covers validation and is encapsulated well within the core and base repository classes. So would a port of S#arp architecture to Db4o make sense of am I still thinking rmdbs in an oodb world? Also is there a best practice for managing indexes (including Unique ones as above) in Db4o? Should they be model metadata based and loaded using DI in a bootstrapper for example or should they be more loaded more like Automapper.CreateMap? Its a bit of a rambling question I know but any thoughts, ideas or suggested reading material is greatly appreciated. Thanks Mac

  • Subscription website architecture questions + SQL Server & .NET

    - by chopps
    Hey Guys, I have a few questions about the architecture of a subscription service I am about to embark on and I am looking for some feedback on how best to set it up. I won’t have a large amount of customers as Basecamp, maybe a few hundred and was wondering what would be a solid architecture for setting up the customer sites. I’m running SQL Server and .NET on a dedicated machine. Should create a new database for each customer as to have control and isolation of data or keep them all in one database? I am also thinking of creating a sub-domain for each customer as well so modifications can be made to each site as needed. The customer URLs would look like this: https://customer1.foobar.com https://customer2.foobar.com I am going to have the ability to ‘plug-in’ reports that will be uploaded to the site so each customer can customize as needed. Off the top of my head this necessitates having each sub domain on its own code-base for the uploading of these reports. So on the main site the customer would sign up for their new subscription and I would programmatically create a new directory for the customer from the main code base and then create a sub domain pointing to the new directory for the customer and then finally their database. Does this sound about right? Am I on the right track? How do other such sites accomplish the same thing? Thanks for letting me bend your ear for a bit on this.

  • ASP.NET MVC application architecture "guidelines"

    - by Joe Future
    I'm looking for some feedback on my ASP.NET MVC based CMS application architecture. Domain Model - depends on nothing but the System classes to define types. For now, mostly anemic. Repository Layer - abstracted data access, only called by the services layer Services Layer - performs business logic on domain models. Exposes view models to the controllers. ViewModelMapper - service that translates back and forth between view models and domain models Controllers - super thin "traffic cop" style functionality that interacts with the service layer and only talks in terms of view models, never domain models My domain model is mostly used as data transfer (DTO) objects and has minimal logic at the moment. I'm finding this is nice because it depends on nothing (not even classes in the services layer). The services layer is a bit tricky... I only want the controllers to have access to viewmodels for ease of GUI programming. However, some of the services need to talk to each other. For example, I have an eventing service that notifies other listener services when content is tagged, when blog posts are created, etc. Currently, the methods that take domain models as inputs or return them are marked internal so they can't be used by the controllers. Sounds like overkill? Not enough abstraction? I'm mainly doing this as a learning exercise in being strict about architecture, not for an actual product, so please no feedback along the lines of "right depends on what you want to do". thanks!

  • Entity Framework in layered architecture

    - by Kamyar
    I am using a layered architecture with the Entity Framework. Here's What I came up with till now (All the projects Except UI are class library): Entities: The POCO Entities. Completely persistence ignorant. No Reference to other projects. Generated by Microsoft's ADO.Net POCO Entity Generator. DAL: The EDMX (Entity Model) file with the context class. (t4 generated). References: Entities BLL: Business Logic Layer. Will implement repository pattern on this layer. References: Entities, DAL. This is where the objectcontext gets populated: var ctx=new DAL.MyDBEntities(); UI: The presentation layer: ASP.NET website. References: Entities, BLL + a connection string entry to entities in the config file (question #2). Now my three questions: Is my layer discintion approach correct? In my UI, I access BLL as follows: var customerRep = new BLL.CustomerRepository(); var Customer = customerRep.GetByID(myCustomerID); The problem is that I have to define the entities connection string in my UI's web.config/app.config otherwise I get a runtime exception. IS defining the entities connectionstring in UI spoils the layers' distinction? Or is it accesptible in a muli layered architecture. Should I take any additional steps to perform chage tracking, lazy loading, etc (by etc I mean the features that Entity Framework covers in a conventional, 1 project, non POCO code generation)? Thanks and apologies for the lengthy question.

  • Architecture advice for converting biz app from old school to new school?

    - by Aaron Anodide
    I've got a WinForms business application that evolved over the past few years. It's forms over data with a number custom UI experiences taylored to the business, so I don't think it's a candidate to port to something like SharePoint or re-write in LightSwitch (at least not without significant investment). When I started it in 2009 I was new to this type of development (coming from more low level programming and my RDBMS knowledge was just slightly greater than what I got from school). Thus, when I was confronted with a business model that operates on a strict monthly accounting cycle, I made the unfortunate decision to create a separate database for each accounting period. Also, when I started I knew DataSets, then I learned Linq2Sql, then I learned EntityFramework. The screens are a mix and match of those. Now, after a few years developing this thing by myself I've finally got a small team. Ultimately, I want a web front end (for remote access to more straight up screens with grids of data) and a thick client (for the highly customized interfaces). My question is: can you offer me some broad strokes architecture advice that will help me formulate a battle plan to convert over to a single database and lay the foundations for my future goals at the same time? Here's a screen shot showing how an older screen uses DataSets and a newer screen uses EF (I'm thinking this might make it more real for someone reading the question - I'm willing to add any amount of detail if someone is willing to help).

  • Best Terminology for a particular php-based site architecture? [closed]

    - by hen3ry
    For a site... o whose overall look-and-feel is generated by one php page ("index.php"). o in which "index.php" provides for all pages served the following required components: The DOCTYPE, opening html tag, the head section, the opening body tag, the end-body tag, and end-html tag. o which uses computed hierarchical navigation menus within "index.php" to offer visitors access to the site content. o in which all content is stored in individual files that contain "headerless html". (The DOCTYPE, etc. etc. being being provided by "index.php" as described above.) Q1: what term best describes this architecture? I'm seeking a concise descriptor that is useful in conversation and definitive as a search term, in whole-web searches, and searching here on Pro Webmasters. Q2: what term best describes the individual content files? Same general goals for the descriptor as above. As you see above, I couldn't avoid using the term "headerless html", my best choice. But this term does not seem to be in general use. I've found some people use this term to describe such as my content files, but others use it quite differently.

  • How to implement behavior in a component-based game architecture?

    - by ghostonline
    I am starting to implement player and enemy AI in a game, but I am confused about how to best implement this in a component-based game architecture. Say I have a following player character that can be stationary, running and swinging a sword. A player can transit to the swing sword state from both the stationary and running state, but then the swing must be completed before the player can resume standing or running around. During the swing, the player cannot walk around. As I see it, I have two implementation approaches: Create a single AI-component containing all player logic (either decoupled from the actual component or embedded as a PlayerAIComponent). I can easily how to enforce the state restrictions without creating coupling between individual components making up the player entity. However, the AI-component cannot be broken up. If I have, for example, an enemy that can only stand and walk around or only walks around and occasionally swing a sword, I have to create new AI-components. Break the behavior up in components, each identifying a specific state. I then get a StandComponent, WalkComponent and SwingComponent. To enforce the transition rules, I have to couple each component. SwingComponent must disable StandComponent and WalkComponent for the duration of the swing. When I have an enemy that only stands around, swinging a sword occasionally, I have to make sure SwingComponent only disables WalkComponent if it is present. Although this allows for better mix-and-matching components, it can lead to a maintainability nightmare as each time a dependency is added, the existing components must be updated to play nicely with the new requirements the dependency places on the character. The ideal situation would be that a designer can build new enemies/players by dragging components into a container, without having to touch a single line of engine or script code. Although I am not sure script coding can be avoided, I want to keep it as simple as possible. Summing it all up: Should I lob all AI logic into one component or break up each logic state into separate components to create entity variants more easily?

  • Where do I read more about building an architecture like Google has? [on hold]

    - by user107148
    I want to develop a program that watches and traverses a rather big network for data. This data should then be available to search through with my program, maybe through a web interface or something. My intuitive thought at the moment is to build an architecture kind of like the one Google has. One "front-end" (the Google Search page) which is essentially a regular web application and one "back-end" (which in Google's case traverses the web). Now for the hard part: If I decide to make such a system, how should communication be done between these parts? One idea I had is to use some kind of database that both the back-end and front-end can access, but then comes the issues of concurrent writes and reads. Another issue with just using a database to communicate is that it makes it hard to "notify" the other part when something changes. Let's say that I want the "front-end" part to push changes to the UI when a change is noticed in the back-end. Then the back-end would have to have some way of notifying the front-end of this.

  • Architecture choice about representation of collections in Business Objects

    - by Rajarshi
    I have made certain choices in my architecture which I request the community to review and comment. I am breaking up the post in smaller sections to make it easier to understand the context and then suggest/comment. I am sorry that the post is long, but is required to explain the context. What am I building A typical business application where there are application users, security roles, business operation/action rights based on roles and several business modules like Stock Receive, Stock Transfer, Sale Order, Sale Invoice, Sale Return, Stock Audit etc. and several reports. The application is a WinForm application since it has a lot of rich and responsive UI requirements and has to operate in disconnected mode (with a local SQL Server), most of the time. What have I done I have built a framework - nothing to boast about, but just a set of libraries that serves the repetative requirements of my application, e.g. authentication, role based authorization, data access, validation, exception handling, logging, change status tracking, presentation model compliance and reasonable loose coupling between components. No, I have not written everything from scratch, you can say I have consolidated many things together like some concepts from CSLA, Martin Fowler for Presentation Model, blocks from Enterprise Library, Unity etc. to build a set of libraries that will help my developers be productive quickly without having to look up Google for many of the technical requirements. I have tried to keep the framework generic so that it can be used in typical business applications and also tried to follow some best practices that will support the same Business Objects to be used in an ASP.NET MVC environment also. My present architecture serves my objectives well, and have built several modules (on WinForm) without much trouble. The architecture also lent itself well to build some usable prototype on ASP.NET MVC with the same set of business objects, without changing a single line of code. My Dilemma I have used Custom Business Objects since that gives me a clearer OOP representation of the problem scope in my solution scope, and helps me visualize my entire solution as collection of objects with data and behavior rather than having a set of relational data (DataSet) and implement behaviours (business logic, validation) etc. separately. With rich databinding support in .NET 2.0 binding Custom Business Objects to UI was a breeze. Now while building my business objects, I am still in a dilemma about representation of collections in business objects. Currently I am using DataSets to represent collections while I have seen many suggestions to implement custom collections. For example, in my vision, a typical Sale Invoice Object will contain 'Sales Invoice Items' as a collection. Now theoritically, I can accept that the each 'Sales Invoice Item' should have its own behavior along with their data (ItemCode, Name, Qty, Price etc.) but typically managing of Sale Invoice Items in a Sale Invoice is handled by the Sale Invoice Object itself, e.g. adding/removing Items from collection. Additionally, we can also put business logic/rules for the Sales Invoice Items like "Qty should not be greater than the ordered qty", "Price should be max 10% above the price in Sale Order" etc. in the Sale Invoice object itself. With that kind of a vision, I felt that most business object child collections can be managed by the parent itself, including add/remove from collection as well and implementing business logic for the collection items, hence the collection items hold nothing but data. Additionally, typical collections are represented in UI in Grids, where ability to support DataBinding becomes very important for any collection. Implementing a custom collection, in that case would also mean, I have to implement robust DataBinding support as well, for the collection, which is of course time consuming. Now, considering child collection behaviors are implemented in the parent and the need for DataBinding of child collections, I chose DataSet to represent any child collection in my business objects. In the above example of Sale Invoice I will have 'Invoice Number', 'Date', 'Customer' etc. as attributes of the 'Sale Invoice' but 'InvoiceItems' as a DataSet. Of course, when I say DataSet, it is not a vanilla dataset but an extended DataSet that supports business rule validation and the same role based security model of my framework to allow/deny any business operation to rows/columns of the DataSet, automatically. This approach has allowed easier collection management and databinding in my business objects and my developers are able to deliver modules rapidly. Questions Do you feel that the approach is reasonable? Do you see any shortcomings of this approach? I am recently thinking of using 'Typed DataSets' as child collections, for easier representation in code, that will allow me to write 'currentInvoice.InvoiceItems' (for the DataTable) and 'invoiceItem.ProductCode' or 'invoiceItem.Qty', instead of 'drow["ProductCode"].ToString()' or '(int)drow["Qty"]' etc. Does this choice have any demerits? Thank you if you have read so far and a salute if you still have the Energy to answer.

  • Pirates, Treasure Chests and Architectural Mapping

    Pirate 1: Why do pirates create treasure maps? Pirate 2: I do not know.Pirate 1: So they can find their gold. Yes, that was a bad joke, but it does illustrate a point. Pirates are known for drawing treasure maps to their most prized possession. These documents detail the decisions pirates made in order to hide and find their chests of gold. The map allows them to trace the steps they took originally to hide their treasure so that they may return. As software engineers, programmers, and architects we need to treat software implementations much like our treasure chest. Why is software like a treasure chest? It cost money, time,  and resources to develop (Usually) It can make or save money, time, and resources (Hopefully) If we operate under the assumption that software is like a treasure chest then wouldn’t make sense to document the steps, rationale, concerns, and decisions about how it was designed? Pirates are notorious for documenting where they hide their treasure.  Shouldn’t we as creators of software do the same? By documenting our design decisions and rationale behind them will help others be able to understand and maintain implemented systems. This can only be done if the design decisions are correctly mapped to its corresponding implementation. This allows for architectural decisions to be traced from the conceptual model, architectural design and finally to the implementation. Mapping gives software professional a method to trace the reason why specific areas of code were developed verses other options. Just like the pirates we need to able to trace our steps from the start of a project to its implementation,  so that we will understand why specific choices were chosen. The traceability of a software implementation that actually maps back to its originating design decisions is invaluable for ensuring that architectural drifting and erosion does not take place. The drifting and erosion is prevented by allowing others to understand the rational of why an implementation was created in a specific manor or methodology The process of mapping distinct design concerns/decisions to the location of its implemented is called traceability. In this context traceability is defined as method for connecting distinctive software artifacts. This process allows architectural design models and decisions to be directly connected with its physical implementation. The process of mapping architectural design concerns to a software implementation can be very complex. However, most design decision can be placed in  a few generalized categories. Commonly Mapped Design Decisions Design Rationale Components and Connectors Interfaces Behaviors/Properties Design rational is one of the hardest categories to map directly to an implementation. Typically this rational is mapped or document in code via comments. These comments consist of general design decisions and reasoning because they do not directly refer to a specific part of an application. They typically focus more on the higher level concerns. Components and connectors can directly be mapped to architectural concerns. Typically concerns subdivide an application in to distinct functional areas. These functional areas then can map directly back to their originating concerns.Interfaces can be mapped back to design concerns in one of two ways. Interfaces that pertain to specific function definitions can be directly mapped back to its originating concern(s). However, more complicated interfaces require additional analysis to ensure that the proper mappings are created. Depending on the complexity some Behaviors\Properties can be translated directly into a generic implementation structure that is ready for business logic. In addition, some behaviors can be translated directly in to an actual implementation depending on the complexity and architectural tools used. Mapping design concerns to an implementation is a lot of work to maintain, but is doable. In order to ensure that concerns are mapped correctly and that an implementation correctly reflects its design concerns then one of two standard approaches are usually used. All Changes Come From ArchitectureBy forcing all application changes to come through the architectural model prior to implementation then the existing mappings will be used to locate where in the implementation changes need to occur. Allow Changes From Implementation Or Architecture By allowing changes to come from the implementation and/or the architecture then the other area must be kept in sync. This methodology is more complex compared to the previous approach.  One reason to justify the added complexity for an application is due to the fact that this approach tends to detect and prevent architectural drift and erosion. Additionally, this approach is usually maintained via software because of the complexity. Reference:Taylor, R. N., Medvidovic, N., & Dashofy, E. M. (2009).

  • Game planning and software design? I feel that UML is not convenient

    - by user1542
    In my university, they always emphasize and hype about UML design and stuff, in which I feel it is not going to work well with game structure design. Now, I just want a professional advice on how should I begin my game designing? The story is I have some skill in programming and have done many minor game such as getting some 2D platformer working to some extend. The problems that I find about my program is the poor quality design. After coding for a while, things start to break down due to poor planning (When I add new feature, it tends to make me have to recode the whole program). However, to plan everything out without a single design flaw is a bit too ideal. Therefore, any advice to how should I plan my game? How should I put it into visible pictures, so that me and my friends are able to overview the designs? I planned to start coding a game with my friend. This is going to be my first teamwork, so any professional advices would be a pleasure. Is there any other alternatives than UML? Another question is how does "prototyping" normally looks like?

  • Project Architecture For Enhancing Legacy project.

    - by vijay.shad
    I am working on legacy project. Now the situation demands project to be divided into parts. What strategy I should follow to do this task. Description: The legacy project (A) is fully functional web application with almost well defined layers. But now i need to extend the project to a further enhancement. This project usage maven as build tool. But it is used only for dependency managements only. (project exported to war form inside eclipse). The new enhancement needs me to add new data table, new UI(jsp, css, js and images). What should be my strategy to enhance to application. My proposed design. I am planing to create two new projects Project B : Main Enhancement works will done in this project. Will have all layers like service layer, dao layer and UI layer in itself. And will be a web application in itself. Project C : Extract some common model and service code form project-A and create this project. This project will be added as dependency to both the projects. If my this approach is okay! Then i presume there will be problem be problem in deployment. These two projects will demand to deploy separately(currently tomcat is used). But I must deploy these two projects as one war. So, i need to have a plan to change the web.xml entries to have configurations for both projects. This will comes with some more complexities with project. What should be my design for the project? Does my plan sounds good.

    In your opinion, which PHP CMS has the best architecture? I don't care about how easy its admin panel is to use, or how many CMS features it has. Right now, I'm after how good its code is (so, please, don't even mention Drupal or Wordpress /shudder). I want to know which ones have a good, solid, OOP codebase. Please provide as much detail as you can in your replies.

  • Performance of a proposed JEE architecture

    - by kineas
    I have concerns about the performance of the following architecture: j2ee application in an appserver, ejb session bean and DAOs remote (rich) client, a swing app. A classic, form-based client only one stateless ejb, the ejb is accessed via web services, not rmi, through a homegrown framework each web service request will get authenticated against an LDAP no state stored on the server, only client-side sessions I guess working on the rich GUI will involve a remote call in every 2-10 seconds, or more, per user. What do you think?
