Managing derived data in intelligent database systems: An implementation study,s in other research prototypes. In addition, this paper introduces several concepts and algorithms key to the implementation, such as the minimal derivation graph, the rule transformation algorithm, and physical rule/data graphs.

Context versions in an object-oriented model,ules. Then the concept of dynamic context is introduced. A dynamic context is composed of context versions and allows to model objects life-cycles. A Petri Net describes conditions under which objects may go from one context version to another.

Interoperability between a distributed system and a database system,on an export/import mechanism that allows a Guide application to ask for remote processing of data stored in the O2 system. A client-server architecture has been implemented for the interconnection and a first prototype allows to validate our approach and to make some performance evaluation.

Inheritance conflicts in object-oriented systems,r design. These conflicts can be resolved by redesigning the schema, renaming properties, redefining (or overriding) an overloaded property, factoring attributes to a more general class, removing redundant ISA relationships and/or explicitly selecting an inheritance path.

Hiroyuki Suga,Y. Igarashi,O. Yamada,Y. Gotoly exist in a database, have multiple versions, and can share structure and behavior with others. In addition, working with design objects is done both associatively (via user-defined identifiers) and declaratively (via collections as a query tool).

Percutaneous Stone Removal Techniquesntional programming. We propose a way to construct prototypes from formal specifications by means of transformation into a kernel language that can be executed in a suitable distributed runtime environment. We introduce the modelling language, the basic execution mechanism, and the basic architecture of the runtime system.

Pablo Rengifo-Moreno MD,Igor F. Palacios MDe size of the data set which must be processed. It is shown that in a parallel environment (as described above) pre-processing of the database (in the algorithms we‘ve tested) achieves too little reduction in run-time to offset the added cost of its execution.
