Hi,
I am pleased to announce the release of ODB 2.1.0.
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:
* Ability to use accessor/modifier functions and expressions to
access data members. In most cases ODB is capable of discovering
suitable accessor/modifier functions automatically.
* Support for virtual (imaginary) data members that can be used to
handle the C++ pimpl idiom as well as aggregate or dis-aggregate
real data members.
* Ability to define database indexes on data members. Multi-member
indexes as well as indexes with database-specific index types,
methods, and options are supported.
* Support for mapping extended database types, such as geospatial
types, user-defined types, collections (arrays, table types, etc.),
key-value stores, XML, JSON, etc., to suitable C++ types.
* The Boost profile library now provides persistence support for
the Uuid and Multi-Index container libraries.
* The Qt profile library now provides persistence support for the
QUuid type.
* Support for generating single (combined) database schema file from
multiple C++ header files.
* SQLite ODB runtime now supports persistence of std::wstring. You can
also pass the database name as std::wstring. The default SQLite mapping
for float and double now allows the NULL value since SQLite treats NaN
values as NULL.
This release also adds support for Visual Studio 2012 and Clang 3.1.
Specifically, all the runtime libraries, examples, and tests now come
with project/solution files for Visual Studio 2012 in addition to 2010
and 2008.
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++ 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), Windows (x86/x86-64), Mac OS X, and Solaris (x86/x86-64/SPARC)
with GNU g++ 4.2.x-4.7.x, MS Visual C++ 2008, 2010, and 2012, Sun Studio 12,
and Clang 3.1.
The currently supported database systems are MySQL, SQLite, PostgreSQL,
Oracle, and SQL Server. ODB also provides profiles for Boost and Qt, which
allow you to seamlessly use value types, containers, and smart pointers
from these libraries in your persistent classes.
