ODB, Advanced Weapons and Tactics

by Boris Kolpackov

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Hiding a relational database behind an ORM does not work. Did I just say that? Yes! Performance and scalability limitations always get in the way. Should we then throw away the whole ORM idea and go back to SQL? We don't have to. In fact, the bulk of ODB features were specifically designed to resolve these limitations without degenerating to JOINs and SQL. And that's what the second part of this talk is all about: bulk operations, object caches, lazy pointers, views, change-tracking containers, optimistic concurrency, object sections (partitions), and prepared and cached queries. By the end of the second half you will be ready for anything that real-world C++ object persistence and database access can throw at you.
