Design and Analysis of an SQL Interface for a Multi-backend Database System

Masters Theses in the Pure and Applied Sciences

Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 29 (thesis year 1984) a total of 12,637 theses titles from 23 Canadian and 202 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 29 reports theses submitted in 1984, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Design and Analysis of an SQL (Structured Query Language) Interface for a Multi-Backend Database System

Recent research in the area of database machines has been directed at achieving greater efficiency and increasing user-friendliness. This thesis is concerned with the second of these research directions, increasing user-friendliness. One development toward increased user-friendliness is the growing acceptance of the relational data model and relational query languages. Relational interfaces provide the user with an easy-to-understand data representation and language with which to manipulate the data. This thesis presents the design and analysis of a relational query language interface, using the SQL relational query language, for the Multi-Backend Database System (MDBS), a database machine which uses the attribute-based model. The purpose is two-fold: first, to provide the user with an easier-to-understand language-to-machine interface, thereby making MDBS available to the wider community of relational database users; second, to investigate how the attribute-based model may be used to support relational databases.
