AIX is a series of proprietary Unix operating systems developed and sold by IBM for several of its computer platforms. Originally released for the IBM RT PC RISC workstation, AIX now supports or has supported a wide variety of hardware platforms, including the IBM RS/6000 series and later POWER and PowerPC-based systems, IBM System i, System/370 mainframes, PS/2 personal computers, and the Apple Network Server.
Lotus 1-2-3 is a discontinued spreadsheet program from Lotus Software. It was the first killer application of the IBM PC, was hugely popular in the 1980s, and significantly contributed to the success of IBM PC-compatibles.
A spreadsheet is a computer application for organization, analysis and storage of data in tabular form. Spreadsheets were developed as computerized analogs of paper accounting worksheets. The program operates on data entered in cells of a table. Each cell may contain either numeric or text data, or the results of formulas that automatically calculate and display a value based on the contents of other cells. A spreadsheet may also refer to one such electronic document.
Lotus Improv is a discontinued spreadsheet program from Lotus Development released in 1991 for the NeXTSTEP platform and then for Windows 3.1 in 1993. Development was put on hiatus in 1994 after slow sales on the Windows platform, and officially ended in April 1996 after Lotus was purchased by IBM.
In marketing terminology, a killer application is any computer program or software that is so necessary or desirable that it proves the core value of some larger technology, such as computer hardware, a video game console, software, a programming language, a software platform, or an operating system. In other words, consumers would buy the hardware just to run that application. A killer app can substantially increase sales of the platform on which it runs.
Db2 is a family of data management products, including database servers, developed by IBM. They initially supported the relational model, but were extended to support object-relational features and non-relational structures like JSON and XML. The brand name was originally styled as DB/2, then DB2 until 2017 and finally changed to its present form.
Wang Laboratories was a computer company founded in 1951, by An Wang and G. Y. Chu. The company was successively headquartered in Cambridge, Massachusetts (1954–1963), Tewksbury, Massachusetts (1963–1976), and finally in Lowell, Massachusetts (1976–1997). At its peak in the 1980s, Wang Laboratories had annual revenues of $3 billion and employed over 33,000 people. It was one of the leading companies during the time of the Massachusetts Miracle.
SPSS Statistics is a software package used for interactive, or batched, statistical analysis. Long produced by SPSS Inc., it was acquired by IBM in 2009. Current versions have the brand name: IBM SPSS Statistics.
This article presents a timeline of events in the history of computer operating systems from 1951 to the current day. For a narrative explaining the overall developments, see the History of operating systems.
Project Athena was a joint project of MIT, Digital Equipment Corporation, and IBM to produce a campus-wide distributed computing environment for educational use. It was launched in 1983, and research and development ran until June 30, 1991, eight years after it began. As of 2020, Athena is still in production use at MIT. It works as software that makes a machine a thin client, that will download educational applications from the MIT servers on demand.
IXI Limited was a British software company that developed and marketed windowing products for Unix, supporting all the popular Unix platforms of the time. Founded in 1987, it was based in Cambridge. The product it was most known for was X.desktop, a desktop environment graphical user interface built on the X Window System. IXI was acquired by the Santa Cruz Operation (SCO) in February 1993.
The MicroVAX was a family of low-cost minicomputers developed and manufactured by Digital Equipment Corporation (DEC). The first model, the MicroVAX I, was introduced in 1983. They used processors that implemented the VAX instruction set architecture (ISA) and were succeeded by the VAX 4000. Many members of the MicroVAX family had corresponding VAXstation variants, which primarily differed by the addition of graphics hardware.
IFPS was a financial modeling language created by professor Gerald R. Wagner and his students of the University of Texas at Austin in the late 1970s. IFPS was marketed by Execucom, an Austin-based company started by Wagner. The company was acquired by Comshare in 1991.
Britton Lee Inc. was a pioneering relational database company. Renamed ShareBase, it was acquired by Teradata in June, 1990.
The ICL DRS was a range of departmental computers from International Computers Limited (ICL). Standing originally for Distributed Resource System, the full name was later dropped in favour of the abbreviation.
Donald Haderle is an American computer scientist and IBM Fellow, best known for his work on relational database management systems (RDBMS). He led the architecture and design of DB2, one of the first commercial RDBMSs, which led to his moniker "Father of DB2." DB2 debuted on IBM's mainframe system MVS in 1983 and validated the applicability of relational databases for high performance transaction processing. With DB2 enterprises store, retrieve, and analyze their business transaction data. The cited reference describes the early technology hurdles, the shift from a monolithic architecture to a distributed architecture portable across many operating systems and the technology collaborations with IBM Research. DB2 is used in most enterprises around the world.
Informix Corporation was a software company located in Menlo Park, California. It was a developer of relational database software for computers using the Unix, Microsoft Windows, and Apple Macintosh operating systems.
The Wollongong Group (TWG) was one of the first companies to sell commercial software products based on the Unix operating system. It was founded to market a port of Unix Version 6 developed by researchers at the University of Wollongong, Australia. The company was active in Palo Alto, California from 1980 to 1995.
Human Computing Resources Corporation, later HCR Corporation, was a Canadian software company that worked on the Unix operating system and system and business software for it. Founded in 1976, it was based in Toronto.
