The automatic generation of test data for a relational database

摘要

A structure for a relational database system is described which involves a new structure called a linkage. A linkage is a set of interdependent relations. Together with relations, tuples, attributes and attribute-values, this provides a hierarchy of structures within which one may specify and generate test data which are not only valid with respect to attribute domains, but preserve dependencies. The discussion refers to an experimental system QIKSYS in which these ideas have been implemented and some of the features of this system are described.
