Database Management Systems (DBMS) technology is a key technology in most Systems Integration (SI) projects. The fast pace of development in this area makes it difficult for IS professionals to keep up with the latest advances, and to appreciate the limitations of the present generation of products. This paper briefly discusses the past achievements of database research and development and comm...

Data warehousing is a corporate strategy that needs to integrate information from several sources of separately developed Database Management Systems (DBMSs). A future DBMS of a data warehouse should provide adequate facilities to manage a wide range of information arising from such integration. We propose that the capabilities of database languages should be enhanced to manipulate user-defined...

Most current information management systems can be classified into text retrieval systems, relational/object database systems, or semistructured/XML database systems. However, in practice, many applications data sets involve a combination of free text, structured data, and semistructured data. Hence, integration of different types of information management systems has been, and continues to be,...

In several working environments, production involves repeated executions of certain procedures. A workflow describes the individual tasks performed in these procedures and their interrelationships. Current Workflow Management Systems (WFMSs) use a Database Management System (DBMS) to store task descriptions, and implement all workflow functionality in modules that run on top of the DBMS. Motiva...

Within our long term interdisciplinary project Nasca/Palpa modern 3D data acquisition techniques were applied for different purposes successfully in the past, particularly for mapping of large and medium scale decorations found in the landscape such as the famous geoglyphs in the Palpa and Nasca regions as well as the petroglyphs of Chichictara. Archaeologists involved in research on the Nasca ...

To get best performance for an analytic system or data warehouse systems, two technologies, column oriented database management systems and main memory database management system can be combined to get advantages of these two. Both technologies give best performance to its opponent database system, for example Main memory database management systems are faster as they reside in main memory as c...
