}}Britton Lee Inc. was a pioneering relational database company. Renamed ShareBase, it was acquired by Teradata in June, 1990.[1]

History

Britton Lee was founded in 1979 by David L. Britton, Geoffrey M. Lee and a group of hardware engineers along with Robert Epstein, Michael Ubell and Paula Hawthorn from the research team that created Ingres.[2]

The company provided a critically acclaimed relational database management system (RDBMS) and supporting parallel-processing database servers.

Epstein later left Britton Lee to help found Sybase. Britton and Lee left the company in 1987.[3]

On May 15, 1989, the company formally changed its name to ShareBase Corporation.[4]

After layoffs and financial losses in 1989, ShareBase was acquired by Teradata in June, 1990.[1]

Products

As of Fall, 1989:[5]

  • ShareBase II (tm): An RDBMS designed for a client/server environment.
  • ShareBase(tm) I: Predecessor to ShareBase II
  • ShareBase SQL Database Server, various models:[6]
    • Server/8000(tm): "Upper-mid-range database server" that supported ShareBase II. Optimized database operations on a RISC/ECL database processor. Used a "distributed function multiprocessor architecture" and included up to 256 megabytes of "shared high-speed data memory." Supported a variety of clients, including IBM PC DOS, Apple Macintosh, Sun, AT&T 3B series computers systems, Pyramid, DEC VAX, HP 3000 and HP 9000, and IBM VM/CMS and MVS.
    • Server/300 (tm), supported ShareBase I and worked with a variety of clients, including PC/DOS, UNIX workstations, AT&T System V, Sun, and DEC VAX with BSD/UNIX, VAX/VMS, or ULTRIX. It also supported up to 50 databases, 32,000 tables per database, 2 billion rows per table, 4 megabytes of memory, and 200 concurrent users.[6]
    • Server/700 (tm), supported ShareBase I,[6] same basic features as the Server/300 but with 6 megabytes of memory and "greater performance for more demanding environments".[6]
  • ShareCom: Communications facilities between database clients and the ShareBase servers.

The Server/300 came in three models:[6]

  • model 25, 600 megabytes of disk storage and one tape drive
  • model 35, 1200 megabytes of disk storage and two tape drives
  • model 60, 3320 megabytes of disk storage and two tape drives

Affiliation with Omnibase/SmartStar

An announcement was made in 1984, that Britton-Lee's Intelligent Database Machine was being sold together with Signal Technology Inc.'s Omnibase and SmartStar relational database software.[7]

This hardware/software combination of Omnibase/Smartstar/Britton Lee Data Base Machine(s),[8][9][10] was used by NASA,[11] USMC[12] and by financial services for analysis.{{cn|date=August 2018}}

SmartStar is Signal Technology Inc (STI)'s application development environment

for the VAX, and it supports[13] several databases using native connections:

RMS,[14] Rdb/VMS, Oracle, Sybase, Ingres, Teradata/ShareBase.

Although before SQL became standard STI's focus was on IQL (Intelligent ? Interactive Query Language), now the query language it supports is SQL.

Components include[15]

  • SmartBuilder
  • SmartDesign
  • SmartStation
  • SmartGL
  • SmartCall and RSQL (for use from 3GL languages)
  • SmartQuery
  • SmartMove (mass load/unload)
  • SmartReport
  • SmartPainter
  • ISQL (Interactive SQL)

Signal Technology Inc

As the above combination moved along, STI and Britton-Lee saw a validation in the form of a review, which confirmed: "there exists no database management system that matches the performance of the IDM with OMNIBASE."[16][17]
