This discussion of the connection between two areas of semantics, namely the semantics of databases and the semantics of natural language, links them via a common view of the semantics of time. It is argued that a coherent theory of the semantics of time is an essential ingredient for the success of efforts to incorporate more "real world" semantics into database models. This idea is a relatively recent concern of database research but it is receiving growing interest. The book opens with a discussion of database querying that motivates the use of the paradigm of Montague Semantics and discusses the details of the intensional logic ILs. This is followed by a description of the author's own model, the Historical Relational Data Model (HRDM), which extends the RDM to include a temporal dimension. Finally the database querying language QEIII is defined and examples illustrate its use. A formal model for the interpretation of questions is presented in this work; it will form the basis for much further research. This text will be valuable for graduate students and researchers in theoretical computer science.
