    New Feature: Artificial Fields

    Artificial fields, what are they good for? OpenAccess requires a persistent class model to work. This means that data not represented by a field in a persistent class cannot be stored or retrieved.  Sometimes you need to add new data to your application during runtime. With many other ORMs you have to add a field to your persistent class, recompile everything and update the database schema.  That is a little unhandy and looks like you always need a developer to do so. OpenAccess Artificial Fields can help you to add such new data definitions on the fly. You can specify...

    Object Scope lifecycle management in web scenarios

    The stateless nature of the Http protocol brings quite a deal of concerns about the handling of the IObjectScope in a web application.

    Telerik OpenAccess ORM and Ado.Net Data Services Example Refreshed part II

    In the first part of this post we looked into providing data to the client using ADO.NET Data Services and Telerik OpenAccess. However it is very rare just to present data, as usually some processing is done by the application on the client side, data gets modified and it is pushed back to the server for persistence. With ADO.NET Data Services this is done by implementing the IUpdateable interface by the data context class used on the server. NOTE: We do not implement IExpandProvider at the moment. They say that a picture is worth a thousand words, so same is true for the...
