    New Demo Web Site for Telerik OpenAccess ORM

    One of the most demanding tasks we always had at the Telerik OpenAccess ORM team, is to demonstrate to our customers and the whole ORM community the capabilities that our product possess. They say a demo is worth 1000 words. I can’t agree more with that. In the case of our product though I would like to add: a video is worth at least for 10 demos. That is the reason why we built a brand new video-oriented web site where we have carefully described each of the most important features (and their count is growing) and all the effort necessary for...

But do you need two datasource controls to do this? The simple answer is NO. You can achieve this...

    How to map references and collections – Part 1

    The references in the object model and the references in the database schema can be defined in several ways. The definitions are following different idioms and it is not straight forward how a mapping can be defined. In the database schema you have the foreign key reference; in the object model you have single references, collections and dictionaries. Let’s look at a simple schema in the database, the Persons table has a foreign key reference to the Addresses table. There are now 3 ways to map this in OpenAccess. 1. You can map it to a reference field which is the...

    Continuing with the LINQ tips, today we provide a list of System.Math methods that we are going to support with the upcoming Q3 release.
