Abstract
This paper presents the database machine DBMAC, a multiprocessor arrchitecture specialized to manage relational databases. DBMAC has been conceived to operate as back-end to a main frame or as a node in a network.
Several are the significant issues of DBMAC. First the physical organization of data, that implements the relational model using a partitioned structure to enhance the parallel processing of the database. Second the logical architecture that presents a high degree of modularity and ample possibility of configuration for the software system distributed over the multiprocessor architecture. Third the physical architecture based essentially on standard off-the-shelf hardware, highly modular and configurable, that allows to build cost effective version of DBMAC for a given application.
Special devices can be (optionally) included in the architecture for a significant gain of performances in the operations of low level database processing.
