The theme of this book is the potential of new advanced

database systems. The volume presents the proceedings of the

10th British National Conference on Databases, held in

Aberdeen, Scotland, in July 1992.

The volume contains two invited papers, one on the promise

of distributed computing andthe challenges of legacy

systems by M.L. Brodie, and the other on object-oriented

requirements capture and analysis and the Orca project by

D.J.L. Gradwell.

The following four parts each contain three submitted papers

selected from a total of 36 submissions. The parts are

entitled:

- Object-oriented databases

- Parallel implementationsand industrial systems

- Non-relational data models

- Logic programming and databases
