Business systems planning (BSP) is a method of analyzing, defining and designing the information architecture of organizations. It was introduced by IBM for internal use only in 1981, [1] although initial work on BSP began during the early 1970s.
The basic idea is to try to divide a system in such a way that each block of the block diagram can be described without an "and" or "or" in the description. This exercise forces each part of the system to have a pure function. When a system is composed of pure functions, they can be reused, or replaced.
IBM stencil for HIPO. HIPO model ( hierarchical input process output model ) is a systems analysis design aid and documentation technique from the 1970s, [ 1 ] used for representing the modules of a system as a hierarchy and for documenting each module.
SVC is a two byte instruction with the hexadecimal operation code 0A; the second byte of the instruction, the SVC number, indicates the specific request. [2] The SVC number can be any value from 0 to 255, with the particular SVC number being up to the implementer of the operating system, e.g. on IBM's MVS, SVC 3 is used to terminate a program, while on the UNIVAC VS/9 and Fujitsu BS2000 ...
Underlying ISPF/PDF is an extensive set of tools that allow application developers to create panel-driven applications, and a set of guidelines to promote consistent use of ISPF functions. A "panel" is a character-based "window" which can encompass all or part of a 3270 session's screen real estate.
The IBM Information Management System (IMS) is a joint hierarchical database and information management system that supports transaction processing. [1] Development began in 1966 to keep track of the bill of materials for the Saturn V rocket of the Apollo program, and the first version on the IBM System/360 Model 65 was completed in 1967 as ICS/DL/I and officially installed in August 1968.
Rhapsody was first released in 1996 by Israeli software company I-Logix Inc. [5] Rhapsody was developed as an object-oriented tool for modeling and executing statecharts, based on work done by David Harel at the Weizmann Institute of Science, who was the first to develop the concept of hierarchical, parallel, and broadcasting statecharts.
Non-IBM SNA software allowed systems other than IBM's to communicate with IBM's mainframes and AS/400 midrange computers using the SNA protocols. Some Unix system vendors, such as Sun Microsystems with its SunLink SNA product line, including PU2.1 Server, [ 31 ] and Hewlett-Packard / Hewlett Packard Enterprise , with their SNAplus2 product ...
