When implementing a multilevel security policy for Object-Oriented Databases (OODBs), several aspects have to be investigated. One of these aspect is the design of multilevel OODB...
Currently the key problems of query optimization are extensibility imposed by object-relational technology, as well as query complexity caused by forthcoming applications, such as...
We consider the problem of ordinal classification, in which a value set of the decision attribute (output, dependent variable) is finite and ordered. This problem shares some chara...
