A C++ wrapper to give an XBase fashion to the Berkeley DB library.

An abstracted C++ database API with advanced transaction management and reliability features. [Open source, GPL]

Provides ODBC recordsets just like STL containers, including writing the contents back to the database.

Collection of interfaces that map C++ objects to relations in SQL and file databases. Uses plug-in architecture for various SQL RDBMS support and provides a simple interface for query processing and object serialization. [Open Source, LGPL]

A C++ library for accessing SQL databases. Designed with standards in mind, so it provides a subset of the well-known JDBC 2.0 and runs on top of ODBC. [Open Source, LGPL]

A C++ object-relational mapping library inspired by Boost.Serialization. In contrast to most serialization libraries with SQL serializers, C++ objects mapped with hiberlite behave similar to active record pattern. [Open Source, GPL]

OCI C++ Interface Library. Download, sample applications, bug tracker.

Oracle, Odbc and DB2-CLI Template Library. A set of classes that wrap around the dynamic database programming interfaces of Oracle, DB2 and ODBC. Also provides support for block-updates and other caching mechanisms.

A database access library for C++ supporting Oracle, PostgreSQL, Firebird, MySQL, SQLite and MS SQL that makes the illusion of embedding SQL queries in the regular C++ code, staying entirely within the Standard C++. [Open Source]

A C++ API for MySQL. Tries to make working with queries as easy as working with other STL containers.
