The classification problem with semantically heterogeneous data,mple procedure for deciding the answerability of a summary query and evaluating it, if answerable. Surprisingly, the condition of derivability is independent of the database instance and is dependent only on the topological properties of the graph modelling the semantical connection of the classification systems adopted.

Handling time in query languages,ogic. New syntax for retrieval statements is defined in order to separate the process of selecting entities (tuples) and the process of selecting required values of temporal attributes from the chosen entities. The extensions presented in this paper offer a good degree of flexibility in expressing different temporal requirements.

GQL, a graphical query language for semantic databases,scribes various aspects of GQL: the underlying model, the pattern images and graphs, and the representation of operations. Implementational issues of a GQL interpreter and its relation to other query languages are also discussed.
