چکیده

On-Line Analytical Processing (OLAP) is a trend in database technology, based on the multidimensional view of data. The aim of this paper is twofold: (a) to list general problems and solutions applicable to the design of any OLAP system and (b) to present the specific design decisions that we made for a prototype under development at NTUA, which we call ERATOSTHENES. The paper addresses requirements and design issues for all three models involved in an OLAP system: the presentational, logical and physical model. It also discusses in detail the architecture and the major components of ERATOSTHENES.

An Architecture for Data Warehousing Supporting Data Independence and Interoperability

We report on the design of a novel architecture for data warehousing based on the introduction of an explicit “logical” layer to the traditional data warehousing framework. This layer serves to guarantee a complete independence of OLAP applications from the physical storage structure of the data warehouse and thus allows users and applications to manipulate multidimensional data ignoring implem...
