摘要

Computing architectures using distributed processing and distributed databases are increasingly becoming considered acceptable solutions for advanced data processing systems. This is occurring even though there is still considerable professional debate as to what ''truly'' distributed computing actually is and despite the relative lack of advanced relational database management software (RDBMS) capable of meeting database and system integrity requirements for developing reliable integrated systems. This study investigates the functionally of ORACLE data base management software that is performing distributed processing between a MicroVAX/VMS minicomputer and three MS-DOS-based microcomputers. The ORACLE database resides on the MicroVAX and is accessed from the microcomputers with ORACLE SQL*NET, DECnet, and ORACLE PC TOOL PACKS. Data gathered during the study reveals that there is a demonstrable decrease in CPU demand on the MicroVAX, due to ''distributed processing'', when the ORACLE PC Tools are used to access the database as opposed to database access from ''dumb'' terminals. Also discovered were several hardware/software constraints that must be considered in implementing various software modules. The results of the study indicate that this distributed data processing architecture is becoming sufficiently mature, reliable, and should be considered for developing applications that reduce processing on central hosts. 33 refs., 2 figs.
