Paper Abstract

This paper describes MODUS, an intelligent data management subsystem currently offered by NCR. This paper also discusses MODUS in an Image Database Management Subsystem. MODUS consists of the hardware and software necessary to communicate via a high level interface to hosts or host networks for the purpose of managing data and peripherals for those hosts. The hardware configuration is an Input/Output Processor, one or more Communication Processors and at least one SCSI Interface to peripherals. The software configuration consists of data and peripheral management Controlware, and multiple optionally supported communication protocols. MODUS will accept high level commands from hosts to access, store and maintain data. Data management features such as multi-user file and database access manage-ment, spacial management, back-up procedures, archival procedures, data security and data integrity are supported. Resource management features such as shared peripherals, hierarchy of memories including cache, standard SCSI interface to peripherals, error logging, print spooling and multiple peripheral types including memory, disks, tapes and optical products are supported. Multiple communication paths can be used with MODUS. Physical connections like NCR OMNINET, RS232 and Ethernet are supported. Communication protocols like CP/NET and Ethernet are available. MODUS would be used in an Image Database Management system for distributed image data storage and retrieval, archival storage management, image data availability and integrity and personnel and patient database management.
