Data Access Components for MySQL (MyDAC) is a library of components that provides direct access to MySQL database servers from Delphi, Delphi for .NET, C++Builder and Kylix. MyDAC can connect directly to MySQL server or work through the MySQL client library. The MyDAC library is designed to help programmers develop faster and cleaner MySQL database applications.

　　MyDAC is a complete replacement for standard MySQL connectivity solutions and presents an efficient alternative to the Borland Database Engine for access to MySQL.
