Abstract

The properties of a computer system's architecture can be examined from the point of view of data processing organization, i.e. centralized and distributed organization; utilization mode, i.e. batch and interactive; and communication function, i.e. number and types of protocols, etc. This paper presents a method of system architecture analysis characterized by a model of the user Job Handling Process (JHP). In order to compare the properties of data processing functions and mechanisms in systems with centralized and distributed architectures, JHP and Open Systems Architecture (OSA) models have been used. The typically applicational approach of the JHP model and the layer approach of the OSA model to the analysis of the system architecture permitted the author to propose an additional layer in the OSA mode. This layer defines the interfaces of "job preparation" mechanisms initiated by the open system user.
