dc.description.abstract | Constraint Databases represent complex data by means of formulas described by constraints (equations,
inequations or Boolean combinations of both). Commercial database management systems allow the storage and
efficient retrieval of classic data, but for complex data a made-to-measure solution combined with expert systems
for each type of problem are necessary. Therefore, in the same way as commercial solutions of relational databases
permit storing and querying classic data, we propose an extension of the Selection Operator for complex data
stored, and an extension of SQL language for the case where both classic and constraint data need to be managed.
This extension shields the user from unnecessary details on how the information is stored and how the queries are
evaluated, thereby enlarging the capacity of expressiveness for any commercial database management system. In
order to minimize the selection time, a set of strategies have been proposed, which combine the advantages of
relational algebra and con-straint data representation. | es |
