Most of the previous studies concerning checking the integrity constraints in distributed
database derive simplified forms of the initial integrity constraints with the sufficiency …

Checking the consistency of a database state generally involves the execution of integrity
tests on the database, which verify whether the database is satisfying its constraints or not …

With the increased use of the applications that deal with massive collections of data, integrity
checking became a critical problem. Efficient checking could be achieved by deriving a …

Distributed database systems (DDBS) usually contain massive collections of data that
rapidly evolve over time. It is extremely time consuming to make a perfect checking at each …

Preserving the accuracy and the integrity of information in a database is extremely important
for the organization that is maintaining that database. Such an organization is likely to rely …

The essential aim of a database system is to guarantee database consistency, which means
that the data contained in a database is both accurate and valid. Checking the consistency …

Repair system has two essential components, which are much related to each other. When
the update operation is executed, the first component is the detection of the erroneous state …

Checking the consistency of a database state generally involves the execution of integrity
tests (query that returns the value true or false) on the database, which verify whether the …

In parallel database systems the partitioning methods considered in current researches are
static. This research paper presents a partitioning method to divide the database relations …
