  • SO what RDF database do i use for product attribute situation initially i thought about using EAV?

    - by keisimone
    Hi, i have a similar issue as espoused in http://stackoverflow.com/questions/695752/product-table-many-kinds-of-product-each-product-has-many-parameters i am convinced to use RDF now. only because of one of the comments made by Bill Karwin in the answer to the above issue but i already have a database in mysql and the code is in php. 1) So what RDF database should I use? 2) do i combine the approach? meaning i have a class table inheritance in the mysql database and just the weird product attributes in the RDF? I dont think i should move everything to a RDF database since it is only just products and the wide array of possible attributes and value that is giving me the problem. 3) what php resources, articles should i look at that will help me better in the creation of this? 4) more articles or resources that helps me to better understand RDF in the context of the above challenge of building something that will better hold all sorts of products' attributes and values will be greatly appreciated. i tend to work better when i have a conceptual understanding of what is going on. Do bear in mind i am a complete novice to this and my knowledge of programming and database is average at best.

  • How do I make software that preserves database integrity and correctness?

    - by user287745
    I have made an application project in Visual Studio 2008 C#, SQL Server from Visual Studio 2008. The database has like 20 tables and many fields in each. I have made an interface for adding deleting editing and retrieving data according to predefined needs of the users. Now I have to Make to project into software which I can deliver to my professor. That is, he can just double click the icon and the software simply starts. No Visual Studio 2008 needed to start the debugging. The database will be on one powerful computer (dual core latest everything Windows XP) and the user will access it from another computer connected using LAN. I am able to change the connection string to the shared database using Visual Studio 2008/ debugger whenever the server changes but how am I supposed to do that when it's software? There will by many clients. Am I supposed to give the same software to every one, so they all can connect to the database? How will the integrity and correctness of the database be maintained? I mean the db.mdf file will be in a folder which will be shared with read and write access. So it's not necessary that only one user will write at a time. So is there any coding for this or?

  • Google app engine - what is the lifecycle of PersistenceManager?

    - by Domchi
    What is the preferred way of using GAE datastore PersistenceManager for web app? GAE instructions are a bit ambiguous on the matter. Do I instantiate PersistenceManagerFactory for each RPC call, or do I use only one factory for all requests? Do I call PMF.get().getPersistenceManager(), or do I call PMF.get().getPersistenceManagerProxy()? Do I close PM after each RPC call, or do I leave it open? What are you guys doing? Furthermore, I'm not certain how GAE handles 30-second-per-request limit. Is it even possible to reference the same PM between requests?

  • Can I specify the order of how changes happen in an single App Engine transaction ? Is it equal to t

    - by indiehacker
    If I passed a list of key ids as an argument in a transaction, would the change associated with the first key in the list happen first? And if not, how do I specify the order that I want the changes to happen in? As a concrete example, consider this code below from Google Docs Transactions--would changes to the first item in acc.key() happen first? class Accumulator(db.Model): counter = db.IntegerProperty() Docshttp://code.google.com/appengine/docs/python/datastore/transactions.html: def increment_counter(key, amount): obj = db.get(key) obj.counter += amount obj.put() q = db.GqlQuery("SELECT * FROM Accumulator") acc = q.get() db.run_in_transaction(increment_counter, acc.key(), 5)

  • How to use a c# datagridview to update a database file just like Access does?

    - by mackeyka
    I have googled everywhere and I am finally giving up and asking here. I am working in Visual Studio 2010 with C#. I have set up a form with a datagridview connected to a MSSQL database and I need to save changes made in the datagridview back to the physical database. I am having some success but I think that I am going about some of it completely wrong because I can not get it to save consistently. What I really want is for the updates to work just like they do when working with Access. When I edit a row in the datagridview and then leave that row, either by selecting another row or by selecting some other control on the form or even by changing to another form or quitting the application the row should be automatically pdated to the physical database. The first part of this question I think is, what is the proper event to use to trigger the save and then second what methods should be used to actually write the data to the database?

  • Image storage as a service

    - by Samuel
    Google App Engine provides a image API for storing / retrieving images. We are currently not in a position to deploy our application on top of App Engine because of limitations in the java frameworks (jboss seam 2.2.0) we are using to build our j2ee application. We would eventually want to deploy our production application on top of Google App Engine, but what are the short term options (java based open source products) which provides comparable functionality to Google App Engine's Image API and will have an easier migration path at a later point in time.

  • How can I load a property lazily in JDO (on Google App Engine)?

    - by luciano
    I have this code in one of my @PersistenceCapable classes: @Persistent private Blob data; The Blob can be quite big, so I'd like to load it lazily since most of the times I don't need it. How can I annotate that property to avoid immediate loading? I could create another class that contains the Blob alone and then use a lazy one-to-one, but I'd like to solve this with annotations.

  • PHP e-commerce site talking to internal database for stock / ordering?

    - by CitrusTree
    Hi. I'm working on an e-commerce site (either bespoke with PHP, or using Drupal/Ubercart), and I'd like to investigate the site interacting with an internal (filemaker) database we use to manage stock and orders. Currently we manually transfer orders from the web site to our own database, and the site does not check or record changes in stock. My plan to allow the 2 to interact is as follows: Make the internal database available externaly on a machine with a fixed IP Allow external access from the site only Connect to the internal database using ODBC (or similar) Use simple queries to check stock / record stock changes / record order details Am I missing something here as this sounds quite straight forward? Is there another solution I should be taking a look at? Thanks in advance for any help or comments.
