Subject:[ANN] ODB C++ ORM 2.3.0 released, adds schema evolution support
View as plain text  
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:

    http://www.codesynthesis.com/products/odb/doc/manual.xhtml#2.9

  * Support for object sections which provide the ability to split data
    members of a persistent C++ class into independently loaded/updated
    groups.

  * Support for automatic mapping of C++11 enum classes.

A more detailed discussion of these features can be found in the following
blog post:

For the complete list of new features in this version see the official
release announcement:

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.

More information, documentation, source code, and pre-compiled binaries are
available from:

Enjoy,
