System 2000[1][2][3] (S2K)[4][5] is a hierarchical database management system (DBMS).[2] Although not a [[Relational database management system|Relational database, S2K does have SQL support.[6] In 2007 it was noted that, while still 'running on systems cranking away in back rooms across the U.S.' it has a problem: "there's little curriculum coverage anymore at universities teaching computer science."[2]

Overview

System 2000 originated as software for the IBM mainframe environment. It could operate in batch processing mode or be used via CICS. [4][7] Unisys and CDC versions were subsequently released, as was an interface to SAS.[8]

Programmers could access its Data manipulation language (DML) via a precompiler;[9] these existed for COBOL, FORTRAN, and ASSEMBLY Language. Statements writen in S2K's Procedural Lanauge could be intermixed with these languages: the 3 character code "*PL" (in columns 1-3) identified these statements as intended for the precompiler (also referred to as a preprocessor[10]).

History

System 2000[11] was developed in 1970.[12] SAS Institute acquired S2K from Intel in 1984, which had acquired it from MRI Systems Corporation in 1979.[13]

MRI was founded by Robert L. Brueck.[14][15]
