Abstract

[Figure containing following caption omitted: New research efforts and recent advances in hardware technology may soon make the commercial Offal Base maze fez rely.] [Footnote] *The title of this introduction is derived from a well- known movie. I must apologize for substituting ";data base machines"; for ";the Russians."; More specifically, the data base machine papers are coming. Not only are there five outstanding tutorial papers in this issue, but the recent issues of the ACM Transactions on Database Systems also have some data base machine papers. Moreover, the IEEE Transactions on Computers will feature a mid-year special issue with at least five research papers on data base machines. This attention, it seems, tells us that there must be much activity in the area of data base machines.

More specifically, the data base machine papers are coming. Not only are there five outstanding tutorial papers in this issue, but the recent issues of the ACM Transactions on Database Systems also have some data base machine papers. Moreover, the IEEE Transactions on Computers will feature a mid-year special issue with at least five research papers on data base machines. This attention, it seems, tells us that there must be much activity in the area of data base machines.

What is a data base machine?

The data base machine consists of specialized computer hardware supporting basic data base management functions found in most contemporary software data base management systems.

Why do we need to perform basic data base management functions in hardware when most functions are available in software?

For reliability -- data base management software grows in complexity and size. This growth is prompted by the increase in user/data base management requirements and by the recent change of data processing mode from an off-line, batch, single-user environment to an on-line, concurrent, multi-user environment. Large and complex software systems tend to be failure- prone. Furthermore, practical verification methods for software systems are still not in sight. On the other hand, methods for verifying hardware functionality, design, and production have long been available. Advanced technology has also overcome some of the problems of logic complexity and capacity requirements, making the construction of relatively large and complex machines viable. By incorporating basic data base management functions into hardware, we can not only provide more reliable basic functions, but we can also improve software reliability since software requirements will be less complex and the system software smaller in size.

For performance -- conventional computer systems were not designed for data base management. These von Neumann-type computers are good for the preparation and execution of programs for numerical computations and for simple data processing. Data base management activity is instead concerned with the storage, retrieval, and management of large data bases and requires quick search (and, sometimes, good update operation) for concurrent access. For example, it is well-know...
