OCGDB-Alpha

OCGDB is built based on SQL/SQLite and become one of the fastest (in terms of speeds of creating and querying/searching), smallest (in terms of database sizes), strongest (in terms of game numbers), and smartest (in terms of querying/position-searching) chess game database programs. The app itself is on intensive development to be an independent, useful chess game database tool.
