Executive Summary

ubQL is a distributed query language for programming large-scale distributed query systems such as resource sharing systems. The language is obtained by adding a small set of mobile process primitives (communication channels, migration operators, etc.) on top of any traditional query language. Queries are encapsulated into processes and can migrate between sites thus enabling cooperation. An important methodological device is the separation of the installation (including migration) of query processes from the distributed execution of the queries.
