MADMAN on the H6000: Data Base Manager for Honeywell 6000 Volume I.

Abstract

MADMAN is a multi-access data base management system that exists on both the PDP-11 and the H6000. This report describes the version that exists on the H6000 under GCOS Versions 1/G, 2/H and 3/I. MADMAN is implemented in such a manner that only one copy of the data base manager is resident on the system for each data base that has been opened. That copy can support a maximum of 16 application programs at one time. The application programs are written in FORTRAN using the CALL statement to access the data base manager. Data is transferred core-to-core between the application programs and the data base manager. Three key features of MADMAN are: complete implementation of the CODASYL network data base standard (except for SELECT UNIQUE MASTER); sophisticated concurrency control with automatic rollback in case of data base conflicts; and automatic rollbacks of processes that were active when systems crashed.
