Open Source C++ Libraries

The database access library for C++ programmers that provides the illusion of embedding SQL in regular C++ code, staying entirely within the C++ standard.

RocksDB uses a log structured database engine, written entirely in C++, for maximum performance. Keys and values are just arbitrarily-sized byte streams. RocksDB is optimized for fast, low latency storage such as flash drives and high-speed disk drives. RocksDB exploits the full potential of high read/write rates offered by flash or RAM. RocksDB is adaptable to different workloads. From database storage engines such as MyRocks to application data caching to embedded workloads, RocksDB can be used for a variety of data needs. RocksDB provides basic operations such as opening and closing a database, reading and writing to more advanced operations such as merging and compaction filters.

Portable C++ RDBMS client library. Provides C++ API and isolates application from low-level DB interactions. Manages database connections, builds and executes SQL statements, parses query results, etc. MySQL, MSSQL, Oracle, SQLite drivers available.

Allows publishing meta-information about DB, functions and interface of your application, which then can be used by various engines and plugins for providing platform-specific interfaces (CORBA,COCOA,COM,Glib,DBus etc.) without additional R&D effort.

Tools Slightly Above the Runtime QueryTool for IBM i based on TSAR: http://www.ibm.com/developerworks/ibmi/library/i-extended-dynamic-sql/index.html

Generic C++ SQL client wrapper over different SQL DB engines. Using a unified interface, it currently supports MySQL/MariaDB, ODBC, PostgreSQL and SQLite.

Simple ADO wrapper based on Stlsoft library (https://sourceforge.net/projects/stlsoft).
