ODB C++ ORM 2.3.0 released, adds schema evolution support
I am pleased to announce the release of ODB 2.3.0.
ODB is an open source object-relational mapping (ORM) system for C++. It
allows you to persist C++ objects to a relational database without having
to deal with tables, columns, or SQL and without manually writing any of
the mapping code.
Major new features in this release:
* Support for database schema evolution, including automatic schema
migration, immediate and gradual data migration, as well as soft
object model changes (ability to work with multiple schema versions
using the same C++ classes).
For a quick showcase of this functionality see the Changing Persistent
Classes section in the Hello World Example chapter:
ODB is written in portable C++ (both C++98/03 and C++11 are supported) and
you should be able to use it with any modern C++ compiler. In particular, we
have tested this release on GNU/Linux (x86/x86-64/ARM), Windows (x86/x86-64),
Mac OS X (x86), and Solaris (x86/x86-64/SPARC) with GNU g++ 4.2.x-4.8.x,
MS Visual C++ 2005, 2008, 2010, and 2012, Sun Studio 12u2, and Clang 3.x.
The currently supported database systems are MySQL, SQLite, PostgreSQL,
Oracle, and SQL Server. ODB also provides optional profiles for Boost and
Qt, which allow you to seamlessly use value types, containers, and smart
pointers from these libraries in your persistent classes.
