چکیده

Due to some given integrity constraints for a medical distributed database we shall now consider the check of the global. In many domains, one cannot suppose to have a full availability of data in a distributed database. Given some integrity constraints over a distributed database we consider the problem of incrementally checking global consistency in response to updates made to the base relation but without accessing all these base relation. We were concerned with the issue of preserving global consistency when updating a distributed database and when not all relationships are available and updates relate to possible relations. 2000 Mathematics Subject Classification: 91A80, 68U99.

Optimizing Distributed Integrity Constraints

Database integrity constraints can be extremely expensive to maintain unless attention is paid to the problem during the design of the database. In the case of distributed databases, and particularly in the case of heterogeneous databases, the problems associated with constraint maintenance are even more acute. We lay the basis for an designtime tool that derives sufficient conditions from the ...

A Strategy for Semantic Integrity Checking in Distributed Databases

Integrity constraints represent knowledge about data with which a database must be consistent. The process of checking constraints to ensure that the update operations or transactions which alter the database will preserve its consistency has proved to be extremely difficult to implement efficiently, particularly in a distributed environment. In the literature, most of the approaches/methods pr...

Consistent Queries over Databases with Integrity Constraints

Integrating data from different sources consists of two main steps, the first in which the various relations are merged together, and the second in which some tuples are removed (or inserted) from the resulting database in order to satisfy integrity constraints. There are several ways to integrate databases or possibly distributed information sources, but whatever integration architecture we ch...

Partial Information Based Integrity Constraint Checking

Integrity constraints are useful for specifying consistent states of a database, especially in distributed database systems where data may be under the control of multiple database managers. Constraints need to be checked when the underlying database is updated. Integrity constraint checking in a distributed environment may involve a distributed transaction and the expenses associated with it: ...
