Shepanski, Michael P., SLOP - An interactive library database system, Department of Computing Science, University of Wollongong, Working Paper 82-12, 1982, 17p.
SLOP is a modular tree-based database system for library management, featuring fast arbitrary data retrieval. Its module structure is briefly discussed together with a superficial review of the support modules, followed by an explanation of the data structures used. Finally the internal control structure of the central module is examined. A knowledge of user-level features of SLOP is assumed.
