While introducing automatic data processing systems in economic units in accordance with the principle of rational economy the attempts should be made at achieving the set goals through possibly lowest input of resources and material means. Costs connected with designing and programming the system represent an essential component of this input. They may be considerably decreased if designers employ standard symbols, documentation, and names throughout the whole period of the system's development and exploitation, while programmers use a single selected language in programming, the available software packages, programme modules or complete programmes. Such unification of automatic data processing systems will allow to construct integrated systems of an industrial branches management, the elements of which would be automatic data processing systems of particular companies. It would, moreover, allow to use effectively gualified computer scientists employed in branch designing centres.
