Mckoi SQL Database is an SQL (Structured Query Language) Database management system written for the Java platform. Mckoi SQL Database is optimized to run as a client/server database server for multiple clients, however it can also be embedded in an application as a stand-alone database. It is highly multi-threaded and features an extendable object-oriented engine.

Mckoi SQL Database started as an internal project and has since evolved from its inception in 1998. The main goals of the project are a code base that is simple to maintain and extend, ease of use and administration, robustness, multiple concurrent access, and performance.
