BIB-VERSION:: CS-TR-v2.0 ID:: STAN//CS-TR-79-778 ENTRY:: June 19, 1995 ORGANIZATION:: Stanford University, Department of Computer Science TITLE:: A hierarchical associative architecture for the parallel evaluation of relational algebraic database primitives TYPE:: Technical Report AUTHOR:: Shaw, David Elliot DATE:: October 1979 PAGES:: 60 ABSTRACT:: Algorithms are described and analyzed for the efficient evaluation of the primitive operators of a relational algebra on a proposed non-von Neumann machine based on a hierarchy of associative storage devices. This architecture permits an O(log n) decrease in time complexity over the best known evaluation methods on a conventional computer system, without the use of redundant storage, and using currently available and potentially competitive technology. In many eases of practical import, the proposed architecture may also permit a significant improvement (by a factor roughly proportional to the capacity of the primary associative storage device) over the performance of previously implemented or proposed database machine architectures based on associative secondary storage devices.
