This paper investigates how database systems would be designed and used under the limiting-case assumption that mass storage is free. It is argued that free mass storage would free database systems from the limitations and problems caused by ...

This paper describes some of the history, general principles and current embodiments of the technology of data storage and retrieval by optical means. It also discusses the utility of some of these embodiments in certain classes of application.

Our focus in this paper is not the design of new and improved hardware for data base management. Instead, our main interest is to document the results of our investigation on the data structuring and indexing requirements of the class of data base ...

The database computer (DBC) is a specialized back-end computer which is capable of managing data 10¹⁰ bytes in size and supporting known data models such as relational, network, hierarchical and attribute-based models. It is also perhaps the first ...

The purpose of this paper is to point out the need for performance evaluation measures and techniques suitable for the evaluation of specialized architectural features in nonnumeric applications. Toward this end, problems associated with the use of data ...

The objective of the research in this paper is the design of a non-numeric processor to be used in the scanning of textual information brought in from serial storage. Source text progresses through a linear array of 32 cells each cell capable of holding ...

This paper discusses the problem of searching very large text databases. It is shown that conventional techniques for searching current databases cannot be scaled up to larger ones, and that it is necessary to build hardware to search the database in ...

Because of the tremendous growth in the terminal-oriented users community, software text editor is increasingly becoming a significant overhead for the computing systems. The files being manipulated by text editors are usually small but undergo rapid ...

In this paper, we present the design of data base processor MAGE. This DBP is based on a hierarchical DB access method. It is composed of two microprocessors, a disk processor and a moving head disk. The processor requirements, design decisions, and ...

Two types of associative mass storage for use in database systems, have been introduced in this paper, they are

I Hybrid associative storage For use as an associative primary storage, it comprise a storing “basement” and an associative surface matrix. ...

This paper discusses about APCAM. APCAM was designed as a practical intelligent parallel search disk for support of relational data base systems. The aim was not to provide a complete relational engine but to provide a machine which would search large ...

Algorithms are described and analyzed for the efficient evaluation of the project and join 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) ...

In a data base computer consisting of cells with processing capability, the desired goal is to achieve an execution time - for each data base operation - to be inversely proportional to the number of cells. Using rings as a basic building block, we have ...

Recent advances in LSI, VLSI and memory technology have led to a reduction in hardware cost and an increase in mass storage capacity such that an associative array memory can be produced and supported. Toward this end, in this paper such an associative ...

MMPS interconnection problems are discussed in terms of a single time-shared bus. The performance drawbacks usually associated with the single bus alternative are attributed to the high bus utilization at the basic building block level. The Pended ...

The purpose of this short paper is to describe some activities in our laboratory on designing a flexible image processor using array processing elements. In many document creation applications, it is desirable to include image handling capability in the ...

The Federal Ministry of Research and Technology (BMFT) took the initiative in starting a project concerning two-way cable television in 1976 at the Heinrich-Hertz-Institute. The two-way cable television provided a model for investigating the ...

Efficiently storing and retrieving data has always been one of the major problems in computer technology. Until recently there has been more interest for the technology of storing and retrieving data in mass memory than for the problem of accessing data ...

LISP is the second oldest computer-programming language still in active use. Our implementation is based on a powerful microprogrammed processor designed specifically for LISP. This processor supports a tagged macro-architecture; it manipulates items ...

This paper describes a high-level query language developed and implemented for the RAP database machine. The language, called SYNGLISH, is based on the semantic structure of the English sentences. The software system developed accepts SYNGLISH queries ...
