Object-instead of function-oriented data management for tool management as an example application

Abstract

Today's situation in data processing in production shows substantial heterogeneity. All data processing systems implemented usually maintain their own databases. CIM strategies often turn out to be bilateral connections between systems. In this way transparency of events as well as the possiblity of reacting quickly cannot surely be enforced. The “transit times for information” are still unsatisfactory, and organization stays slow. The importance of data management as a strategic problem becomes more and more apparent. A common database can serve as an integration kernel for a CIM concept. This database should be generated and maintained independently from specific applications. The internal representation of data in the database system is of fundamental importance. On one hand it should comply with the requirements of the user programs and should be a comprehensive picture of reality; on the other hand it should be easy to survey and render possible safe data maintenance. A suitable approach for modelling data is to orient the model to the objects of the real world. This way a system for data maintenance can be created which supplies all users with comprehensive information. Fast access to information that is always up to date guarantees the ability to react quickly and is a fundamental prerequisite for the application of highly developed data processing systems. Computer-aided production will remain but a wish for many enterprises unless due attention is paid to data management.
