MS-SQL

In June 2008, Made to Order Software created a new software library called odbcpp. This library is an Open Source C++ wrapper of the Open Database Connectivity (ODBC) library started by Microsoft in 1988.

ODBC hides the details of back-end database systems. In other words, if you support ODBC, you can effortlessly connect to a very large number of database systems such as MS-SQL, Access, Oracle, MySQL and PostgreSQL.
