Natural English as a query language offers the ultimate in directness for man-machine communications and has new and powerful potentials for interactive problem solving. The linguistic problems underlying machine interpretation and generation of natural English, however, have been slow in yielding to solution, though recent successes have raised new ...

When storing data in heterogeneous databases, one of the top-down design issues concerns the usage of multiple query languages. A common language enables querying of database schemas in a platform independent format. This is particularly useful in federated database systems when newly added databases may be both numerous and heterogeneous.

We investigate the expressive power of query languages with counting ability. We define a LOGSPACE extension of first order logic and a PTIME extension of fixpoint logic with counters. We develop specific techniques, such as games, for dealing with languages with counters and therefore integers. We prove in particular that the arity of the tuples which

Computational Power in Query Languages
SIAM Journal on Computing, 1982Primitive recursion, recursion and partial recursion are defined for languages which query a relational data base. Necessary and sufficient conditions for a language to satisfy these properties are given. The computational power of several extensions of the relational algebra is considered.

The t4sql temporal query language
Proceedings of the sixteenth ACM conference on Conference on information and knowledge management, 2007Time characterizes every aspect of our life and its management when storing and querying data is very important. In this paper we propose a new temporal query language, called T4SQL, supporting multiple temporal dimensions of data. Besides the well-known valid and transaction times, it encompasses two additional temporal dimensions, namely ...

We define the query language Vizla, in which answers to queries are built up by pointing to representations of sets and functions in a conceptual model of the data base of an application, and to iconic identifiers of computational operators or control constructs.

A multimedia query specification language
Proceedings. International Workshop on Multi-Media Database Management Systems, 1996Typically, multimedia applications involve thousands of hours of video, images, audio, text and graphics that need to be stored, retrieved and manipulated in a large multimedia database. There is therefore an important need for novel techniques and systems which provide an efficient retrieval facility of the voluminous information stored in the ...
