PICK, a non-relational multi-user database management system developed in the 60's by Richard A. Pick ("Dick Pick"). Originally implemented on Honeywell and McDonnell Douglas minicomputers, the relative simplicity and portability of the PICK model has led to ports for a wide range of platforms, and spurred the refinements that led to Advanced PICK. Client-server implementations, using ODBC and/or OSFI, are available as D3/UNIX, D3/NT (32-bit Windows platforms), and D3/ProPlus (Linux).
