    Using the ObjectContainer in disconnected scenarios – Part 2

    How to get objects into the ObjectContainer? The ObjectContainer contains a closed world of instances, no reference is dangling and pointing out of the container. That means, the instance graph is contained completely in this 'workspace'. Of course, at some points the need arises to prune the graph, as otherwise the whole database content would need to be stored in the containers memory. This is no different to the connected IObjectScope, but in the scope, we can directly perform the loading of objects from the database (lazy loading). With the container, there is no connection to a database,...

    Using LinqPad with Telerik OpenAccess ORM

    LinqPad is a nice and popular query analyzer made to test LINQ queries: whether it is Linq To Sql, Linq to Objects or some other flavor, you will be able to play in a nice way with it. Sadly it does not support Telerik OpenAccess ORM out of the box. However we never said it is impossible – you just have to put some more pressure to it. So, the first step is of course to deploy Telerik OpenAccess ORM and LinqPad on your machine. Then do the following: a) Open LinqPad and press F4 to bring up the Advanced Query...

    LINQ Tip of the Week: Optimizing query execution by using parameterized queries

    This is the first post of the series that have the goal to help Telerik OpenAccess ORM users enhance their experience in Linq against OpenAccess persistent objects. The two areas where performance enhancement can be taken advantage of are reusing a Linq query from the query cache and altering the query in a way where bigger portions of it are executed on the server. Today we will share with you a tip about the first one. When a Linq query is requested for execution, the query goes through a step of compilation – where the Linq query expression tree...

    Using the latest Web Testing Tools along with the latest RadControls

    Closely monitoring the customer feedback on our web testing tools, I noticed that various issues have actually been caused by outdated versions of the RadControls used along with the most recent testing tools versions. Please note that we highly recommend using the versions of RadControls and the testing tools from the exact same release. Let me explain why. I completely understand why customers do not always upgrade their applications with the latest RadControls (at least not immediately). “If it works, do not touch it” is a common principle. Of course that’s a matter of choice. However, as a ...

    Tracing the SQL Statements Generated by Telerik OpenAccess ORM

    One of the main jobs that the ORM software should handle is communicating with the database server and generating SQL statements for reading and writing data. Undoubtedly, the performance of each application developed by using an ORM tool depends on the generated SQL. It is a responsibility of the ORM software to optimize each statement and avoid unnecessary queries. So, when you are facing a difficult choice of an O/R Mapper, it is always meaningful to see and compare how your data is treated by different products. However, not all database engines are distributed with additional profiling software for observing...
