MySQL Data Access Components (MyDAC) is a library of components that provides direct access to MySQL from Delphi, C++Builder, Lazarus (and Free Pascal) on Windows, Mac OS X, iOS, Android, Linux, and FreeBSD for both 32-bit and 64-bit platforms. Applications based on MyDAC can connect directly to MySQL server or work through the MySQL client library. MyDAC 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 (BDE) and standard dbExpress driver for access to MySQL.
