How to Think Like the Entity Framework
Craig Stuntz – Vertex Systems
Relevant to: Delphi
In order to use the ADO.NET Entity Framework effectively, you must understand its value-based data model, which is distinctly different from the SQL and ORM approaches to representing and querying data. Programmers who approach the Entity Framework as "just another ORM" often find themselves frustrated or disappointed, a common reaction to trying to force a square peg into a round hole. This presentation examines the Entity Data Model in-depth, explaining where it fits into the context of a larger application, and demonstrates different techniques for retrieving and altering data. Also covered are performance considerations and future directions.
This session takes you *very* deep in the rabbit hole that hides the LINQ internals in Delphi Prism. All the secrets and all the compiler magic behind LINQ is explained in detail, so that you will be able to use only parts of LINQ where they help you. Especially lambda expressions and the way you can use them with extension methods will make your coding-Fu far more powerful than now, and this goes even further down.
