Definition: Pick System

A multiuser operating system and database management system (DBMS) that runs on x86, Linux and Unix platforms. Introduced in 1965, Pick has been highly praised for its flexibility and advanced features. The DBMS portion of the Pick System was widely used in third-party products. R83 is the original Pick System. R93 and Advanced Pick are later versions. D3 is the DBMS, and D3 Pro Plus is a Linux/DBMS package.

The Pick System was originally developed for the U.S. Army by Richard Pick while working at TRW Corporation. He later transformed it into the Reality operating system for Microdata and then obtained the rights to license it to several other companies. In 2000, Pick Systems, Inc. merged with Omnis Technology Corporation to become Raining Data Corporation. Raining Data was later renamed TigerLogic, which dissolved in 2016.
