Towards data and object modelling

What is it about?

In the paper we survey research results of the Database Research Group at Charles University Prague during last 10 years. Its activities have been focused mainly on applying a functional approach to conceptual modelling and modelling of objects via relational databases. The former research direction influenced also an approach to a formalization of object-oriented models and, recently, OLAP and data warehouses modelling. The latter research concerned a persistence of objects and a study, how to implant high-level query capabilities in C++. In the context of the ADOORE project, a practical implementation — a general library (GENLIB) is now at disposal, where objects are stored in a relational database. To enhance queering objects, high-level query capabilities are possible.
