  • Transmitting Form Data from the Client to the Web Server

    The steps involved in transmitting form data from the client to the web server User loads web form User enters data in to web form fields User clicks submit On submit page validates fields using JavaScript. If validation errors are found then the validation script stops the browser from canceling posting the data to the web server and displays error messages as needed If the form passes the data validation process then the browser will URL encode the values of every field and post it to the server.  The server reads the posted data from the query string and then again validates the data just to ensure data consistency and to prevent any non-validated data because JavaScript was turned off on the clients browser from being inserted in to a database or passed on to other process If the data passes the second validation check then the server side code will continue with the requested processes

  • Consuming JSON stream into AWS Database on the cheap

    - by wjl
    I'm working on a project that needs to consume a JSON stream (approximately 1MB / minute), and parse and insert objects into a database. Amazon's DynamoDB or SimpleDB seem like attractive options for this. Is there a web service that can run a very simple script to eat the data and put it in a database? I could use a worker on Heroku or Elastic Beanstalk, or even pure EC2, but I'd like to find a service that's much cheaper, due to the very low amount of bandwidth and CPU required. (Sorry for the crappy tags. I'm not even sure where to categorize this question.)

  • Connecting to an Amazon AWS database [closed]

    - by Adel
    so I'm a bit overwhelmed/bewildered by the whole concept of networking/remote-desktop , etc. The context is that - in my company I need to access a remote database. The standard way I use is to first connect using a VPN-Client( called Shrew Soft Access manager), then once that says: "network device configured tunnel enabled" I'm good to connect using windows "Remote Desktop Connection" . But now our company set up an Amazon AWS database, and I'm told I need to connect, and I ony need to use RDP. So I tried the standard windows one - but it doesn't work. On wikipedia , I looked up remote desktop sftware and downloaded one called VNC Viewer. but it doesn't work. Any advice/tips/comments appreciated EDIT: YAYA! I finally got a little more connected . I had to use my username as a fully qualified name: Computer: XYZ.XYZ.XYZ.XYZ USERNAME: XYZ.XYZ.XYZ.XYZ\aazzam

  • The Other Side of XBRL

    - by john.orourke(at)oracle.com
    With the United States SEC's mandate for XBRL filings entering its third year, and impacting over 7000 additional companies in 2011, there's a lot of buzz in the industry about how companies should address the new reporting requirements.  Should they outsource the XBRL tagging process to a third party publisher, handle the process in-house with a bolt-on XBRL tool, or should they integrate XBRL tagging with the financial close and reporting process?  Oracle is recommending the latter approach, in fact  here's a link to a recent webcast that I did with CFO.com on this topic: http://www.cfo.com/webcasts/index.cfm/l_eventarchive/14548560 But production of XBRL-based filings is only half of the story. The other half is consumption of XBRL by regulators, academics, financial analysts and investors.  As I mentioned in my December article on the XBRL US conference, the feedback from these groups is that they are not really leveraging XBRL for analysis of companies due to a lack of tools and historic XBRL-based data on public companies.   The good news here is that the historic data problem is getting better as large, accelerated filers enter their third year of XBRL filings.  And the situation is getting better on the reporting and analysis tools side of the equation as well - and Oracle is leading the way. In early January, Oracle released the Oracle XBRL Extension for Oracle Database 11g.  This is a "no cost option" on top of the latest Oracle Database 11.2.0.2.0 release. With this added functionality organizations will have the ability to create one or more back-end XBRL repositories based on Oracle Database, which provide XBRL storage and query-ability with a set of XBRL-specific services.  The XBRL Extension to Oracle XML DB integrates easily with Oracle Business Intelligence Suite Enterprise Edition (OBIEE) for analytics and with interactive development environments (IDEs) and design tools for creating and editing XBRL taxonomies. The Oracle XBRL Extension to Oracle Database 11g should be attractive to regulators, stock exchanges, universities and other organizations that need to collect, analyze and disseminate XBRL-based filings.  It should also be attractive to organizations that produce XBRL filings, and need a way to store and compare their own XBRL-based financial filings to those of their peers and competitors. If you would like more information, here's a link to a web page on the Oracle Technology Network with the details about Oracle XBRL Extension for Oracle Database 11g, including data sheet, white paper, presentation, demos and other information: http://www.oracle.com/technetwork/database/features/xmldb/index-087631.html

  • Why should I adopt MVC?

    - by Andrew
    I decided to get my hands wet and got the YII framework for PHP. I created my first application, then created new controller, model and view. Connected to database, got my record passed from controller to the view and printed the hello world. I am confused now. If I have to do the same thing for each page, this seems like a nightmare to me. In each controller I have to do a lot of same operations - declare variables, and pass them to views. I also need to create models for each page and this is all confusing to me. In my idea the main goal of development is to avoid duplication, but what I see here is lots and lots of duplicated code. Please advise and clarify. Maybe you could suggest a good reading about MVC and coding patterns and best practices in MVC. Because so far, it takes much more time to create a small site using MVC than using my own programming schema.

  • Is there such thing as a portable database that runs easily OsX and Windows?

    - by Jean-Philippe Murray
    I need to make a small database for a project at school (not computer related at all, I'm indexing and categorizing paper documents of a research projet). The thing is that in september, my semester is over and other students will have to taker over the project (and so on, for every semester!), so I'd need something that would be free and OS agnostic (or at least OsX/Windows) so it would easily be given to the next students on the project. I was thinking about a WAMP running USB key that would have a MySQL / HTML interface, but it will become locked to the OS I choose first. LibreOffice and the likes will be an option in the end if I don't find anything truly portable. Anyone has a solution in mind?

  • Facebook Game database design

    - by facebook-100000781341887
    Hi, I'm currently develop a facebook mafia like PHP game(of course, a light weight version), here is a simplify database(MySQL) of the game id-a <int3> <for index> uid <chr15> <facebook uid> HP <int3> <health point> exp <int3> <experience> money <int3> <money> list_inventory <chr5> <the inventory user hold...some special here, talk next> ... and 20 other fields just like reputation, num of combat... *the number next to the type is the size(byte) of the type For the list_inventory, there have 40 inventorys in my game, (actually, I have 5 these kind of list in my database), and each user can only contain 1 qty of each inventory, therefore, I assign 5 char for this field and each bit of char as 1 item(5 char * 8 bit = 40 slot), and I will do some manipulation by PHP to extract the data from this 5 byte. OK, I was thinking on this, if this game contains 100,000 user, and only 10% are active, therefore, if use my method, for the space use, 5 byte * 100,000 = 500 KB if I use another method, create a table user_hold_inventory, if the user have the inventory, then insert a record into this table, so, for 10,000 active user, I assume they got all item, but for other, I assume they got no item, here is the fields of the new table id-b <int3> <for index> id-a <int3> <id of the user table> inv_no <int1> <inventory that user hold> for the space use, ([id] (3+3) byte + [inv_no] 1 byte ) * [active user] 10,000 * [all inventory] * 40 = 2.8 MB seems method 2 have use more space, but it consume less CPU power. Please comment these 2 method or please correct me if there have another better method rather than what I think. Another question is, my database contain 26 fields, but I counted 5 of them are not change frquently, should I need to separate it on the other table or not? So many words, thanks for reading :)

  • How to keep a generic process unique?

    - by Steve Van Opstal
    I'm currently working on a project that makes connection between different banks which send us information on which that project replies. A part of that project configures the different protocols that are used (not every bank uses the same protocol), this runs on a separate server. These processes all have unique id's which are stored in a database. But to save time and money on configurations and new processes, we want to make a generic protocol that banks can use. Because of PCI requirements we have to make a separate process for every bank we connect to. But the generic process has only 1 unique identifier and therefor we cannot keep them apart. Giving every copy of that process a different identifier is as I see it impossible because they run entirely separate. So how do I keep my generic process unique?

  • need example sql transaction procedures for sales tracking or financial database [closed]

    - by fa1c0n3r
    hi, i am making a database for an accounting/sales type system similar to a car sales database and would like to make some transactions for the following real world actions salesman creates new product shipped onto floor (itempk, car make, year, price).   salesman changes price.   salesman creates sale entry for product sold (salespk, itemforeignkey, price sold, salesman).   salesman cancels item for removed product.   salesman cancels sale for cancelled sale    the examples i have found online are too generic...like this is a transaction... i would like something resembling what i am trying to do to understand it.  anybody have some good similar or related sql examples i can look at to design these? do people use transactions for sales databases?  or if you have done this kind of sql transaction before could you make an outline for how these could be made?  thanks  my thread so far on stack overflow... http://stackoverflow.com/q/4975484/613799

  • Aus 2 mach 1: Oracle Audit Vault and Database Firewall

    - by Heinz-Wilhelm Fabry (DBA Community)
    Gestern hat Oracle bekanntgegeben, dass die beiden Produkte Oracle Audit Vault und Oracle Database Firewall zu einem Produkt werden. Der neue Produktname wird "Oracle Audit Vault and Database Firewall" sein. Software und Dokumentation werden in den nächsten Tagen zum Download verfügbar sein. Das Zusammenlegen macht durchaus Sinn, denn die ursprünglichen Produkte wiesen im Bereich der Protokollierung und des Berichtswesens deutliche Überschneidungen auf. Damit lag es nahe, die Repositories für das Speichern des Protokolls zu vereinheitlichen. Endlich wird es im Bereich Auditing durch die Einführung eines Development Kits auch möglich sein, Systeme anzubinden, für die Oracle keine vorgefertigten Konnektoren / Kollektoren liefert. Mit der Zusammenlegung verbunden ist ein völlig neues Lizenzierungsmodell, das zu deutlichen Kostensenkungen für kleinere und mittlere Installationen führt.

  • Design Pattern for building a Budget

    - by Scott
    So I've looked at the Builder Pattern, Abstract Interfaces, other design patterns, etc. - and I think I'm over thinking the simplicity behind what I'm trying to do, so I'm asking you guys for some help with either recommending a design pattern I should use, or an architecture style I'm not familiar with that fits my task. So I have one model that represents a Budget in my code. At a high level, it looks like this: public class Budget { public int Id { get; set; } public List<MonthlySummary> Months { get; set; } public float SavingsPriority { get; set; } public float DebtPriority { get; set; } public List<Savings> SavingsCollection { get; set; } public UserProjectionParameters UserProjectionParameters { get; set; } public List<Debt> DebtCollection { get; set; } public string Name { get; set; } public List<Expense> Expenses { get; set; } public List<Income> IncomeCollection { get; set; } public bool AutoSave { get; set; } public decimal AutoSaveAmount { get; set; } public FundType AutoSaveType { get; set; } public decimal TotalExcess { get; set; } public decimal AccountMinimum { get; set; } } To go into more detail about some of the properties here shouldn't be necessary, but if you have any questions about those I will fill more out for you guys. Now, I'm trying to create code that builds one of these things based on a set of BudgetBuildParameters that the user will create and supply. There are going to be multiple types of these parameters. For example, on the sites homepage, there will be an example section where you can quickly see what your numbers look like, so they would be a much simpler set of SampleBudgetBuildParameters then say after a user registers and wants to create a fully filled out Budget using much more information in the DebtBudgetBuildParameters. Now a lot of these builds are going to be using similar code for certain tasks, but might want to also check the status of a users DebtCollection when formulating a monthly spending report, where as a Budget that only focuses on savings might not want to. I'd like to reduce code duplication (obviously) as much as possible, but in my head, every way I can think to do this would require using a base BudgetBuilderFactory to return the correct builder to the caller, and then creating say a SimpleBudgetBuilder that inherits from a BudgetBuilder, and put all duplicate code in the BudgetBuilder, and let the SimpleBudgetBuilder handle it's own cases. Problem is, a lot of the unique cases are unique to 2/4 builders, so there will be duplicate code somewhere in there obviously if I did that. Can anyone think of a better way to either explain a solution to this that may or may not be similar to mine, or a completely different pattern or way of thinking here? I really appreciate it.

  • open source database project

    - by Jeff V
    What is the best way to build an open source database? I would like to build a database of all vehicles and the related maintenance information (i.e Oil Weight, Quantity, Tire Pressure, Windshield wipers etc). Currently this information is fragmented or just not put on line in an open way. Once collection began I would want to import into a DB and then be able to distribute freely. Is there a process (site or group) that I can start gathering this information in a reliable and verifiable way? Is there any issues that I should watch out for?

One query I find I use pretty often is the following one that lists the files in the database. In this blog I will include 3 queries.  The first will deal with files and databases, and the second runs in a database to see the files and their filegroups (If there...(read more)

  • Looking for a real-world example illustrating that composition can be superior to inheritance

    - by Job
    I watched a bunch of lectures on Clojure and functional programming by Rich Hickey as well as some of the SICP lectures, and I am sold on many concepts of functional programming. I incorporated some of them into my C# code at a previous job, and luckily it was easy to write C# code in a more functional style. At my new job we use Python and multiple inheritance is all the rage. My co-workers are very smart but they have to produce code fast given the nature of the company. I am learning both the tools and the codebase, but the architecture itself slows me down as well. I have not written the existing class hierarchy (neither would I be able to remember everything about it), and so, when I started adding a fairly small feature, I realized that I had to read a lot of code in the process. At the surface the code is neatly organized and split into small functions/methods and not copy-paste-repetitive, but the flip side of being not repetitive is that there is some magic functionality hidden somewhere in the hierarchy chain that magically glues things together and does work on my behalf, but it is very hard to find and follow. I had to fire up a profiler and run it through several examples and plot the execution graph as well as step through a debugger a few times, search the code for some substring and just read pages at the time. I am pretty sure that once I am done, my resulting code will be short and neatly organized, and yet not very readable. What I write feels declarative, as if I was writing an XML file that drives some other magic engine, except that there is no clear documentation on what the XML should look like and what the engine does except for the existing examples that I can read as well as the source code for the 'engine'. There has got to be a better way. IMO using composition over inheritance can help quite a bit. That way the computation will be linear rather than jumping all over the hierarchy tree. Whenever the functionality does not quite fit into an inheritance model, it will need to be mangled to fit in, or the entire inheritance hierarchy will need to be refactored/rebalanced, sort of like an unbalanced binary tree needs reshuffling from time to time in order to improve the average seek time. As I mentioned before, my co-workers are very smart; they just have been doing things a certain way and probably have an ability to hold a lot of unrelated crap in their head at once. I want to convince them to give composition and functional as opposed to OOP approach a try. To do that, I need to find some very good material. I do not think that a SCIP lecture or one by Rich Hickey will do - I am afraid it will be flagged down as too academic. Then, simple examples of Dog and Frog and AddressBook classes do not really connivence one way or the other - they show how inheritance can be converted to composition but not why it is truly and objectively better. What I am looking for is some real-world example of code that has been written with a lot of inheritance, then hit a wall and re-written in a different style that uses composition. Perhaps there is a blog or a chapter. I am looking for something that can summarize and illustrate the sort of pain that I am going through. I already have been throwing the phrase "composition over inheritance" around, but it was not received as enthusiastically as I had hoped. I do not want to be perceived as a new guy who likes to complain and bash existing code while looking for a perfect approach while not contributing fast enough. At the same time, my gut is convinced that inheritance is often the instrument of evil and I want to show a better way in a near future. Have you stumbled upon any great resources that can help me?

  • .NET DAL and arhitecture

    - by Parhs
    I have seen lots of articles but none really help me. That is because I want to use dapper as a DAL. Should I create repositories with special functions? Like getStaffActive()? If I use repositories I can implement with dapper-extension a generic crud I have no idea how to handle database connection. Where to open the connection? If I do this at every function then how am I supposed to use transaction scope? Somehow the repositories I work with should share a connection in order transaction to work. But how to do this? Openning connection in BLL? If I use queries and execute them directly then still the same thing.
