Explore an in-depth conference talk on ODB, an open-source object-relational mapping (ORM) system for C++. Dive into the progress made over two years, covering topics such as C++11 support, Boost and Qt profiles, polymorphism, optimistic concurrency, and multi-database support. Learn how to easily persist C++ objects in relational databases without dealing with tables, columns, or SQL. Discover the intricacies of database schema evolution, non-intrusive mapping, and performance optimization techniques. Gain insights into ODB's workflow, compiler, database instances, and query examples. Understand the implementation of lazy pointers, circular references, and change tracking containers. Master the concepts of composite values, ODB views, and optimistic concurrency in C++ database programming.
