Relational database systems represent the current standard technology for implementing database applications. Now that the object-oriented paradigm becomes more and more mature in all phases of the software engineerin...

In an object-oriented database, classes are organized according to three types of relationship, namely generalization, association and aggregation relationships. These relationships, which impact the query language in...

Recently, we have extended the relational data model to in-corporate linear orderings into data domains [8], which we call the or-dered relational model. We herein formally define Ordered Functional Dependencies (OFDs...

Constraint databases (CDBs) are the combination of Constraint Logic Programming (CLP, which is one of the strategic directions in computing research) and database technology. CDBs represent a new kind of post-relational databases, naturally extending relational, deductive, or object-oriented databases by making feasible the use of constraints to represent possibly infinite but representable complex data. This paper discusses constraint query languages and their expressive powers, constraint queer, evaluation and optimization techniques, CDBs prototype systems and promising directions of research on CDBs.
We consider the problem of on-line database reorganization. The types of reorganization that we discuss are restoration of clustering, purging of old data, creation of a backup copy, compaction, and construction of in...

In most current database systems, data is updated in-place. In order to support recovery and increase performance, write-ahead logging is used. This logging defers the in-place updates, ho w ever sooner or later, the ...

Can the benefits of re-use and patterns that are so well known in software design and implementation be carried over into analysis and database design? The fledgling field of Analysis Patterns has provided only a part...
