Extending OLAP Querying to External Object Databases

On-Line Analytical Processing (OLAP) systems based on a multidimensional view of data have found widespread use in business applications and are being used increasingly in non-standard applications. These systems provide good performance and ease-of-use. However, the complex structures and relationships inherent in data in non-standard applications are not accommodated well by OLAP systems. In contrast, object database systems are built to handle such complexity, but do not support OLAP-type querying well. This paper presents the concepts and techniques underlying a flexible, “multi-model” federated system that enables OLAP users to exploit simultaneously the features of OLAP and object database systems. The system allows data to be handled using the most appropriate data model and technology: OLAP systems for multidimensional data and object database systems for more complex, general data. Additionally, physical data integration can be avoided. As a vehicle for demonstrating the...
