Sarson, Trish
Trish Sarson (born 1946) is a British/American computer scientist, consultant and information technology writer, known for developing data flow diagrams with Chris Gane in the 1970s. Born in England, Sarson obtained her BA in Zoology and Chemistry at the Royal Holloway, University of London in the 1960s. She emigrated to the United States in 1975, where she joined Ed Yourdon's software company. In 1977 with Chris Gane she founded Improved Systems Technologies (IST), which became a relatively large and successful company. In 1977 they published their best known work ''Structured Systems Analysis: Tools and Techniques,'' in which they presented a specific type of data flow diagrams.Allen Kent, James G. Williams (eds.)

Royal Holloway, University Of London
Royal Holloway, University of London (RH), formally incorporated as Royal Holloway and Bedford New College, is a public university, public research university and a constituent college, member institution of the federal University of London. It has six schools, 21 academic departments and approximately 10,500 undergraduate and postgraduate students from more than 100 countries. The campus is located west of Egham, Surrey, from central London. The Egham campus was founded in 1879 by the Victorian entrepreneur and philanthropist Thomas Holloway. Royal Holloway College was officially opened in 1886 by Queen Victoria as an Single-sex education, all-women college. It became a member of the University of London in 1900. In 1945, the college admitted male postgraduate students, and in 1965, around 100 of the first male undergraduates. In 1985, Royal Holloway merged with Bedford College (London), Bedford College (another former all-women's college in London). The merged college was nam ...

Data Flow Diagram
A data-flow diagram is a way of representing a flow of data through a process or a system (usually an information system). The DFD also provides information about the outputs and inputs of each entity and the process itself. A data-flow diagram has no control are no decision rules and no loops. Specific operations based on the data can be represented by a flowchart. There are several notations for displaying data-flow diagrams. The notation presented above was described in 1979 by Tom DeMarco as part of structured analysis. For each data flow, at least one of the endpoints (source and / or destination) must exist in a process. The refined representation of a process can be done in another data-flow diagram, which subdivides this process into sub-processes. The data-flow diagram is a tool that is part of structured analysis, data modeling and threat modeling. When using Unified Modeling Language, UML, the activity diagram typically takes over the role of the data-flow diagram. A ...

Christopher P
Christopher is the English version of a Europe-wide name derived from the Greek name Χριστόφορος (''Christophoros'' or '' Christoforos''). The constituent parts are Χριστός (''Christós''), "Christ" or "Anointed", and φέρειν (''phérein''), "to bear"; hence the "Christ-bearer". As a given name, 'Christopher' has been in use since the 10th century. In English, Christopher may be abbreviated as "Chris", "Topher", and sometimes " Kit". It was frequently the most popular male first name in the United Kingdom, having been in the top twenty in England and Wales from the 1940s until 1995, although it has since dropped out of the top 100. Within the United Kingdom, the name is most common in England and not so common in Wales, Scotland, or Northern Ireland.

Ed Yourdon
Edward Nash Yourdon (April 30, 1944 – January 20, 2016) was an American software engineer, computer consultant, author and lecturer, and software engineering methodology pioneer. He was one of the lead developers of the structured analysis techniques of the 1970s and a co-developer of both the Yourdon/Whitehead method for object-oriented analysis/design in the late 1980s and the Coad/Yourdon methodology for object-oriented analysis/design in the 1990s. Biography Yourdon obtained his B.S. in applied mathematics from Massachusetts Institute of Technology (MIT) in 1965, and did graduate work in electrical engineering and computer science at MIT and the Polytechnic Institute of New York. In 1964 Yourdon started working at Digital Equipment Corporation developing FORTRAN programs for the PDP-5 minicomputer and later assembler for the PDP-8. In the late 1960s and early 1970s he worked at a small consulting firm and as an independent consultant. In 1974 Yourdon founded his own ...
