Some approaches to the theory of information systems

  • B. Langefors


A formal method for performing systems analysis of information systems in business and elsewhere is needed in order to save systems work and programming and to obtain better systems.

For organization and handling of information and data a formal procedure based on graph-theoretic concepts is described. It is shown that data transport in the system is determined by file volumes and the systems topology and expressed by the “topological transport factor”. The quality of the system design can be measured by its transport factor and the relation of this to the topological transport factor.

On this basis future development of algorithms for minimal data transport and of standard lists for file contents and typical transport factors are expected. Much of the systems analysis and synthesis work can then be done by computers.

It is also shown how the organization of file records is determined by the systems network.
