  • Behavior-Driven Development / Use case diagram

    - by Mik378
    Regarding growing of Behavior-Driven Development imposing acceptance testing, are use cases diagram useful or do they lead to an "over-documentation"? Indeed, acceptance tests representing specifications by example, as use cases promote despite of a more generic manner (since cases, not scenarios), aren't they too similar to treat them both at the time of a newly created project? From this link, one opinion is: Another realization I had is that if you do UseCases and automated AcceptanceTests you are essentially doubling your work. There is duplication between the UseCases and the AcceptanceTests. I think there is a good case to be made that UserStories + AcceptanceTests are more efficient way to work when compared to UseCases + AcceptanceTests. What to think about?

  • How to show an "or includes" relationship - UML Use case diagram

    - by TheNewBlack
    I haven't come across this issue before and can't find it in my Schaum's Outline UML book and was wondering if someone here could help. I'm making a use case diagram for e-commerce, and in it I want to describe that in order to add a book to your shopping basket, you have to either search products (using the websites search engine) or browse products (using navigation). But the thing is that it can be either one, and not both. Is there a way to show that adding a product to the basket needs to include either this or that? Because otherwise it would look like it needs to include both. Or should I join the two use cases (search products and browse products) into one?

  • Most appropriate diagram for GUI button design?

    - by JustADude
    What is the most appropriate diagram for GUI button design? Specifically, I have numerous buttons that will be changing color based on state information from operator input and input from various subcomponents and sensors. I would like to use UML or some other type of design diagrams to be able to capture the color transition. Some folks have suggested sequence diagrams, but I haven't been able to find any good examples that show how to incorporate this design artifact. I would really like to head in this direction to help developers. Thanks a ton for feedback and insights.

  • How to draw an E-R diagram?

    - by Appy
    I am learning DBMS in my college. Recently I was given an assignment to draw a E-R Model of a Bus Reservation system which handles Reservations, Ticketing and cancellations. I understand the theory about E-R model when I study from a book, but it gets confusing when I try to draw one from scratch. How should one proceed? There seem to be a lot of ways to model a E-R diagram for a particular requirement. It's really confusing. Can anyone explain taking Bus reservation System as an example? Here is the model I made (But I am not confident with it because at every step, I could think of many more alternatives!) - Entity_Set Passenger(passengerID,name,age,gender) Entity_Set Ticket(ticketID,status) //Status is either WaitingList , Confirmed or Cancelled Entity_Set Bus (busID,MaxSeats,Type) //Type is Ac or Non-AC Entity_Set Route(routeID,ArrivalTime,DepartureTime,Source,Destination) And a Ternary relationship between Passenger, Ticket and Bus with attributes as passengerID, ticketID, busID . Binary relationship between Bus and Route with attributes as busID, routeID . I have few doubts regarding - 1 . Should we take Time as a composite attribute with Arrival and Departure as its attributes (What's the difference if we take that way?) 2 . The same with Source and Destination. Should they be made into a composite attribute "Place" or something like "Location"? 3. Are there any weak entity sets here? Can you please 'create' a weak entity set and explain? Because I have no idea at all what to take as a Weak entity set?

  • Launch Webcast Q&A: Oracle WebCenter Suite 11g - The Platform for the Modern User Experience

    - by howard.beader(at)oracle.com
    Did you have a chance to watch the Oracle WebCenter Suite 11g Launch Webcast yet? Andy MacMillan presented some great information on the webcast and answered quite a few of your questions in the Q&A session as well. For your reading pleasure we have captured a number of the questions and answers and they are summarized below: Question: Can you tell me what should our Portal strategy be for integrating and extending our Oracle enterprise applications? Answer: We recommend that you look at this in two steps, the first would be to ensure that you have a good understanding of our common user experience architecture. Internally our product teams at Oracle are already investing in this quite heavily today for Fusion Applications and this is driving natural convergence from a UX strategy standpoint. The second step would be to look at how best to componentize the back office applications so that the business users across your organization can take advantage of these -- don't make it just about putting a new skin on top of what you already have from an application standpoint, instead look at how best to embed the social computing capabilities as part of the solution for your business users. Question: We are currently using the BEA WebLogic Portal now, should we stay on WLP or should we be looking at moving to WebCenter or when should we move to WebCenter? Answer: Our strategy has been called "Continue & Converge", this theme means that you can continue to use WebLogic or Plumtree portals until your organization is ready to move to WebCenter and in the mean time you can continue to deploy what you need to in your organization of WLP or WCI Portals with the full support of Oracle. In addition WebCenter Services can be leveraged for social computing to complement what you are already doing today and enable your organization to take advantage of some of the latest and greatest social computing capabilities. We have migration scripts and conversion capabilities available as well as programs where Oracle can help you evaluate your options to decide how best to move forward. WebCenter provides the best of the best capabilities and will enable you to take advantage of new capabilities that may not exist in your current portal today. In the end though it's up to you as a customer as to when you want to make the transition to Oracle WebCenter Suite. Question: Can you tell me how is Oracle leveraging WebCenter internally and for its Application and Middleware product UX strategies? Answer: Internally, Oracle is leveraging WebCenter for our employees and thus far we are seeing significant updates with our users taking advantage of the business activity streams, team spaces and collaboration capabilities. From a product strategy standpoint, our product teams are taking advantage of the common user experience architecture and leveraging WebCenter to provide social and collaborative capabilities to the Oracle Applications and providing new types of composite applications with what is coming with Fusion Applications. WebCenter also provides a common user experience across all the products in the Oracle Fusion Middleware family as well. Question: Our organization is currently using SharePoint, but we are also an Oracle Applications customer, how should we be thinking about WebCenter as we move forward? Answer: Great question. Typically, we are seeing organizations using SharePoint for its core use cases of small team collaboration and file server replacement. WebCenter can connect to SharePoint as a content source to feed into WebCenter quite easily and it leverages the robust Oracle ECM product under WebCenter as well. In addition, SharePoint team sites can be connected to WebCenter utilizing our SharePoint connector. With Oracle WebCenter though, we are really targeting business users and enterprise applications, thus affecting positive change on the processes that drive the business to improve productivity across your organization. Question: Are organizations today using WebCenter as a Web platform for externally facing public websites? Answer: Yes, we are seeing a convergence around web content management and portal types of websites with customers converting them from just broadcasting content to making it a much richer personalized experience and also exposing back-office applications as well. Web Content Management capabilities are already embedded in WebCenter so that organizations can take advantage now of the benefits a personalized web experience provides for your customers. This is simply a short summary of a few of the questions addressed on the webcast, please tune in now to learn more about Oracle WebCenter, the user experience platform for the enterprise and the web! The Oracle WebCenter Suite 11g Launch Webcast can be found here

  • Diagram to show code responsibility

    - by Mike Samuel
    Does anyone know how to visually diagram the ways in which the flow of control in code passes between code produced by different groups and how that affects the amount of code that needs to be carefully written/reviewed/tested for system properties to hold? What I am trying to help people visualize are arguments of the form: For property P to hold, nd developers have to write application code, Ca, without certain kinds of errors, and nm maintainers have to make sure that the code continues to not have these kinds of errors over the project lifetime. We could reduce the error rate by educating nd developers and nm maintainers. For us to be confident that the property holds, ns specialists still need to test or check |Ca| lines of code and continue to test/check the changes by nm maintainers. Alternatively, we could be confident that P holds if all code paths that could violate P went through tool code, Ct, written by our specialists. In our case, test suites alone cannot give confidence that P holdsnd » nsnm ns|Ca| » |Ct| so writing and maintaining Ct is economical, frees up our developers to worry about other things, and reduces the ongoing education commitment by our specialists. or those conditions do not hold, so focusing on education and testing is preferable. Example 1 As a concrete example, suppose we want to ensure that our web-service only produces valid JSON output. Our web-service provides several query and mutation operators that can be composed in interesting ways. We could try to educate everyone who maintains those operations about the JSON syntax, the importance of conformance, and libraries available so that when they write to an output buffer, every possible sequence of appends results in syntactically valid JSON. Alternatively, we don't expose an output stream handle to application code, and instead expose a JSON sink so that every code path that writes a response is channeled through a JSON sink that is written and maintained by a specialist who knows JSON syntax and can use well-written libraries to produce only valid output. Example 2 We need to make sure that a service that receives a URL from an untrusted source and tries to fetch its content does not end up revealing sensitive files from the file-system, like file:///etc/passwd. If there is a single standard way that any developer familiar with the application language's libraries would use to fetch URLs, which has file-system access turned off by default, then simply educating developers about the standard mechanism, and testing that file probing fails for some inputs, will probably be sufficient.

  • How can I create a class diagram with NetBeans' 6.8 UML module?

    - by Karussell
    It seems to me the UML module of NetBeans is a bit too much hidden. In NetBeans 6.5 it was very easy to create an UML diagram. No plugin installation necessary or sth. like. Read my post where I found a zip file to install the UML module. And now, after this procedure, I got the UML module back, but it seems to me that I cannot create class diagram with it. Do you know how I can do this with NetBeans 6.8? Update1: There seems to be no support Update2: Nevertheless somebody seems to got it working.

  • Link objects as fields in UML diagram

    - by fearofawhackplanet
    I'm trying to generate a diagram for a design document. I've generated a class diagram in VS. At the moment it's just a bunch of unconnected boxes as there isn't any inheritance going on. It feels like it would be more useful if I could show how the objects interact through properties and parameters. As an example, a Boy class has a method Kiss which takes a Girl object. How can I show that Boy and Girl interact by connecting this in the diagram? Is there a notation for this in UML? Or is there another type of diagram that shows this? Can I make VS draw this connection for me somehow? Or is this a silly/useless idea? It just doesn't feel like a proper diagram unless it's got some lines on it somewhere :)

  • How can a large company foster excellence in its engineers?

    - by Joshiatto
    I am tasked with improving the skills (quality & speed) of engineers in my company. Here are some ideas: Pair Programming TDD Automated Check-in Policies Talks given by experts Awards for coding excellence Encourage competition among engineers to contribute to GitHub Publish standards and practices docs on the intranet site "Gamification" of engineering. Somehow make becoming badasses into a game they will enjoy playing Training Showcase github checkins on screens around the office Add an "engineer of the month" to the intranet home page How can I drive traffic to the intranet home page? What crazy futuristic idea would drive engineers to go to the page every day to see who of their peers are making more money than them (inferred via recognition) and then go off and improve their skills and productivity to see their standings improve on the home page??? Or any ideas just to foster collaboration and love for their jobs so they start taking more pride in their work?? Don't take my ideas as symptomatic of our org. I take full responsibility for not knowing the right way to do this.

  • PHP Doxygen Collaboration Diagrams

    - by Shabbyrobe
    I've started playing around with doxygen to generate documentation from my PHP code. I notice there are two diagrams in the generated output - inheritance and collaboration. I know about the inheritance one, but the collaboration one has piqued my interest since reading the manual: If the COLLABORATION_GRAPH and HAVE_DOT tags are set to YES then doxygen will generate a graph for each documented class showing the direct and indirect implementation dependencies (inheritance, containment, and class references variables) of the class with other documented classes. The impression I get from that description is that composition relationships should be represented by the collaboration diagram as well, but it always seems to just be identical to the inheritance one. Is there something I can do to hint to Doxygen the things I would like to appear in this diagram? Does it just not work with PHP?

  • Microsoft Office documents collaboration - Open Source alternative

    - by Saggi Malachi
    I am looking for a good solution to collaborate on Microsoft Office documents, we currently just edit directly on a Samba share but it's one big mess because sometimes people leave the office with their laptops while docs are open so swap files remain there and then you nobody is sure what's going on. Is there any good and simple open source solution based on Linux? I've tried Alfresco but it is much more than what I need, we got an internal wiki for most collaboration and I just need some solution for the stuff we need to do in Microsoft Office (mostly Excel files, the rest is in the wiki) EDIT: Some more info as requested - we are very small group, 4 full time employees and a few freelancers. The best idea I've got so far is just managing it in a subversion repository with a Lock-Modify-Lock policy but I'd love to hear about better solutions. Thanks!

  • How to learn to draw UML sequence diagrams

    - by PeterT
    How can I learn to draw UML sequence diagrams. Even though I don't use UML much I find that type of diagrams to be quite expressive and want to learn how to draw them. I don't plan to use them to visualise a large chunks of code, hence I would like to avoid using tools, and learn how to draw them with just pen and paper. Muscle memory is good. I guess I would need to learn some basics of notation first, and then just practice it like in "take the piece of code, draw a seq. diagram visualising the code, then generate the diagram using some tool/website, then compare what I'd drawn to what the tool result. Find the differences, correct them, repeat.". Where do I start? Can you recommend a book or a web site or something else?

  • Sequence for authentication on a decoupled client?

    - by A T
    Using a sequence diagram and example code could you explain to me how authentication works when the client is completely separated from the server? I.e.: you haven't generated any of the client using a server-side template engine, rather you are communicating using REST (SOAP xor HTTP) xor RPC (XML xor JSON) with javascript on the client-side. Specifically I would like to know the sequence of: Authenticating using basic auth (user+pass) with "my" server Authenticating using OAuth2, e.g.: with Facebook, with facebook's server then whatever extra steps are needed for "my" server And how it could be implemented. (feel free to use psuedo-code [like below] or [preferably] prototyped simply using BackboneJS, AngularJS, EmberJS, BatmanJS, AgilityJS, SammyJS xor ActiveJS. if cookie.status in [Expired, Tampered, Wrong IP, Invalid, Not Found]: try auth(user,pass): if user is in my db: try authenticate(user,pass) if successful: login user # give session-cookie here? else: present user with "auth failed" msg else if user not in db: redirect to "edit-profile" page PS: I have written an example (editable) auth sequence diagram; based on facebooks' documentation.

  • Suggestions for getting an open source electron beam tracking code going

    - by Boaz
    I work in the field of accelerator physics and synchrotron radiation. High energy electrons circulating in large rings of magnets produce x-rays that are used for a variety of different kinds of science. Running and improving these facilities requires controlling and modelling the electron beam as it circulates in the ring. A code to model this basically requires trackers to follow the electrons through the elements (something called a symplectic integrator), and then the computation of different parameters associated with this motion. The problem with these codes is that every facility has there own. In principle the code is not so complex. And as a modelling project, one might think it has some general interest. Who doesn't want to be able to create a track in space out of magnets and watch the electrons circulate? There is a Matlab based code to do this called Accelerator Toolbox, but the creator of the code is no longer in the field. I put the code in Sourceforge under the name atcollab. The basic resource is in C- it is the set of symplectic integrators. These are available in the atcollab code here. It has been useful to put the code on Sourceforge in order to exchange code, but the community of users is quite small and most are too busy to put that much time into collaboration. So in terms of really improving the code, I don't think it has been so successful. Any piece of this picture could be recreated without that much difficulty, but overall it is a bit complex, and because each lab has their own installation with lots of add-on Matlab code, people find it hard to really work together and share code. Somehow I think we need to involve a wider community in our development, or just use some standard tools. But for that, I suppose it needs to be of some general interest. I think symplectic integrators may have some general interest. And the part about a plug-in architecture to build up the ring ought to fit other patterns. Or the other option is to just accept that this is not a problem of general interest, and work harder within our small community. Suggestions, or anecdotes of analogous experience would be appreciated.

  • Weird Excel bar diagram behaviour

    - by Simon
    I have a very simple question. I want to have a diagram with the following table: Apple 30 40 50 Pears 200 300 400 Bananas 10 20 30 The weird thing is, when I try to draw a bar diagram the order of the bars changes. So Excel first draws the bananas, then the pears, and finally the apple bar... Is there anyway to tell Excel 2003 to keep the original order? Thank you very much

  • SQL 2005 - any way to restore/copy a diagram?

    - by NealWalters
    I used the Redgate packager (ran MSI) to reset all the data in my database (i.e. I deleted everything, and let it build the new database). Unfortunately, I discovered that it didn't retain my diagrams, which has a nice arrangement and several annotations. Is there any way to copy/migrate/script the diagram from one database to another (the databases have identical structures). Thanks, Neal Walters

  • Enterprise 2.0 - Connecting People, Processes & Content

    - by kellsey.ruppel(at)oracle.com
    With recent technological advances, the Internet is changing. When users head to the web, they are no longer just looking for information from a simple text and picture based website. Users want a more interactive experience - they want to participate, to share their views and get the feedback of others. And this is precisely what Web 2.0 technology addresses. Web 2.0 is about web applications that facilitate interactive information sharing, user-centered design and collaboration on the World Wide Web. Web 2.0 technology is everywhere on the Internet and is radically changing the speed and medium in which we interact and communicate. There are thousands of examples in the consumer world of Web 2.0 applications, technologies and solutions at work. You might be familiar with some of them...blogs, wikis (Wikipedia), Twitter, Facebook, LinkedIn - these are all examples of Web 2.0. And these technologies are transforming our world into a real-time, participation-oriented, user-driven, content-centric world. With all of these Web 2.0 solutions it's about the user, the consumer and all the content they are generating. It's a world full of online communities where people share and participate. We're not talking about disseminating information top-down , nor is it a bottom-up fight. Everyone has an equal opportunity to participate and share. The more you participate, the more you share, the more valued you are in the community. The web is not just a collection of documents online. It is the social web.  For the active users in the community, staying connected becomes critically important so they can participate at anytime and from anywhere. And because feedback and interaction are so critical, time is of the essence. When everyone is providing immediate responses, you feel the urge to do the same. Hence everything needs to be done right now, together...and collaboratively. With all the content being generated online by users, there is complete information overload out there. (That's a good thing for Google). But...it's no longer just about search. Sometimes you want the information to just come to you. Recommendations and discovery engines will deliver you more applicable results than a non-contextual search. How many of you have heard about a news headline on Facebook as part of your feed before you read the paper or see it on TV? This is how the new generation of workers live their daily lives...and as they enter the workforce, these trends and technologies are showing up in the enterprise too. A lot of the Web 2.0 technologies and solutions in the consumer world are geared for just that....consumers. But the core concepts that put them into the Web 2.0 category can be applied to the enterprise as well. And that is what we mean when we talk about Enterprise 2.0. Enterprise 2.0 is the use of Web 2.0 tools and technologies in the workplace.  It provides a modern user experience by connecting the people, content and business processes inside and outside the enterprise. Enterprise 2.0 empowers users to collaborate more effectively, find and share information in the proper content and improves the overall business processes which they participate in. As we head into 2011, is your organization using Enterprise 2.0 capabilities to the fullest? Are you connecting your people, processes and content together to provide a modern user experience?

  • Visualize flowchart diagram with multiple end symbols

    - by platzhirsch
    I am looking for a standardize way to visualize the following hierarchical logic: The state of the thread is represented by the answers to the hierarchical set of question You can read this listing like a flowchart, you iterate over the questions decide, go one step deeper and so on. Therefore I thought the best way to visualize it, using a flowchart. The problem is, in this hierarchical set it is possible to end in more than one state and its totally valid. I have never seen a flowchart where you can enter more than one state. Is it still possible and I am missing the right symbol to present this logic or are flowchart not fitting anyway? What other graphical representation could I use, is there something fitting in UML? A non-deterministic state machine seems not to be intuitive enough, transfering it into a deterministic state machine would result in to many states, and so on.
