Designing the Reengineering Service for the DOK Federated Database System (1997) [5 citations — 4 self]
Abstract:
This paper addresses the design of the reengineering service for federated databases. This service allows the hiding of the heterogeneity of databases involved in afederation by generating object-oriented representations from their corresponding schemata. We propose acomplete methodology that supports the identi cation and the translation of both the explicit and implicit information. The identi cation of object-oriented constructs is performed by classifying a relational schema into di erent category of relations, namely base, dependent, and composite relations. The main di culty in designing the reengineering service relies on the distinction between the di erent types of relationships amongst classes. Our approach deals with this problem by analysing relations according two types of correlation: (i) the degree ofcorrelation between the external and primary keys, (ii) and the degree ofcorrelation between sets of tuples in the relations. Examining these correlations uncovers implicit relationships contained as well hidden classes in a relational schema. 1.
