Modelling Data Warehouses and OLAP Applications by Means of Dialogue Objects
نویسندگان
چکیده
The idea of data warehouses is to provide condensed information in order to support managers in the analysis of business facts such as sales, costs, proots, etc. along various dimensions such as geography , organisation, time, etc. The analysis should allow fast switches between diierent selected multiple dimensions at diierent granularity. The task itself is usually called on-line analytical processing (OLAP). We show in this paper how to model data warehouses with OLAP func-tionality by means of dialogue objects. These are extended and possibly materialised views on collections of operative databases and couple structural and behavioural aspects of application units.

Representing Temporal Data in Non-Temporal OLAP Systems
Multidimensional data warehouses and OLAP systems do not provide adequate means for dealing with changes in dimension data, changes appearing frequently in dynamic application areas as current business systems. As data warehouses and OLAP tools serve as decision support systems they have to reflect such changes. Temporal data warehouses propose sophisticated modelling tools for covering any cha...
متن کاملQuerying Cardinal Directions between Complex Objects in Data Warehouses
Data warehouses help to store and analyze large multidimensional datasets and provide enterprise decision support. With an increased availability of spatial data in recent years, several new strategies have been proposed to enable their integration into data warehouses and and perform complex OLAP analysis. Cardinal directions have turned out to be very important qualitative spatial relations d...
متن کاملBuilding Conflict-Aware Profiling Ontology from Data Warehouses
User profiles or user models are crucial in many areas in which it is essential to obtain knowledge about users of software applications such as data warehouse technologies. To enhance the personalized services, group profiles are derived through combining individual user profiles in order to represent group modelling. In this paper, we propose a new representation of group profiles in OLAP con...
متن کاملDesigning Distributed Data Warehouses and OLAP Systems
On-line analytical processing (OLAP) systems deal with analytical tasks in businesses. As these tasks do not depend on the latest updates by transactions, it is assumed that the data used in OLAP systems are kept in a data warehouse, which separates the input coming from operational databases from the output going to dialogue interfaces for OLAP. In this article we present a 3-tier architecture...
