One of the requirements of multimedia database systems is that they will need a data model more powerful than the relational model, without compromising its advantages. The relational data model exhibits limitations in terms of complex object support, type system, and object management.

An epidemiological database system
International Journal of Bio-Medical Computing, 1978An epidemiological database system is presented. It is a system built around the concepts of record structure and location, and of processing of the data item values so stored. It is designed to operate in many situations with a minimum of programming, and to be easily expanded to more complex situations by adding new program modules to those already ...

Database integration in a distributed heterogeneous database system
1986 IEEE Second International Conference on Data Engineering, 1986This paper describes the approach to database integration in a heterogeneous distributed database environment utilized by the Amoco Distributed Database System (ADDS). We start with the definition of the extended relational data model that is used by ADDS for database integration.

A spatial database as a component of integrated database system
Proceedings 1999 International Symposium on Database Applications in Non-Traditional Environments (DANTE'99) (Cat. No.PR00496), 2003Huge amounts of spatial data have been accumulated by government agencies and other organizations for various kinds of applications, such as land information management, asset and facility management, resource management, and environment management. These data are typically collected, stored and used by different custodians for very specific purposes ...

Distributed and parallel database systems
ACM Computing Surveys, 1996The maturation of database management system (DBMS) technology has coincided with significant developments in distributed computing and parallel processing technologies. The end result is the development of distributed database management systems and parallel database management systems that are now the dominant data management tools for highly data ...

Database and Database Management System
2009In this set of examples, we will try to set out the criteria which an inventor should bear in mind when attempting to decide on the appropriate type of protection to apply for when his invention relates to a database. We will first define what a database and a database management system are and then the different possibilities to get intellectual ...

Query Optimization in Database Systems
ACM Computing Surveys, 1984Summary: Efficient methods of processing unanticipated queries are a crucial prerequisite for the success of generalized database management systems. A wide variety of approaches to improve the performance of query evaluation algorithms have been proposed: logic-based and semantic transformations, fast implementations of basic operations, and ...
