Database Component Ware

Database modeling is still a job of an artisan. Due to this approach database schemata evolve by growth without any evolution plan. Finally, they cannot be examined, surveyed, consistently extended or analyzed. Querying and maintenance become very difficult. Distribution of database fragments becomes a performance bottleneck. Currently, databases evolve to huge databases. Their development must be performed with the highest care. This paper aims in developing an approach to systematic schema composition based on components. The approach is based on the internal skeletal metastructures inside the schema. We develop a theory of database components which can be composed to schemata following a architecture skeleton of the entire database. 1 Towards Information Systems Engineering Observations. Database modeling is usually carried out by handicraft. Database developers know a number of methods and apply them with high craftman’s skills. Monographs and database course books usually base...
