“…Another four level model, similar in concept to the one we suggest here, was suggested by Sibley [SIB74]. Research has been done on the formalization of these levels and the transforma tion between them, directed mainly toward data transla tion [YAM74] or data base simulation [SCH74]. Though we could have developed most of our notions in the framework of one of these models, we prefer to develop our own terminology and structure for two major reasons.…”

This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again-beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understanding of the dissertation. Silver prints of "photographs" may be ordered at additional charge by writing the Order Department, giving the catalog number, title, author and specific pages you wish reproduced. 5. PLEASE NOTE: Some pages may have indistinct print. Filmed as received.

This paper addresses the problem of application program conversion to account for changes in database semantics that result in changes in the schema and database contents. With the observation that the existing data models can be viewed as alternative ways of modeling the same database semantics, a methodology of application program analysis and conversion based on an existing-DBMS-model-and schema-independent representation of both the database and programs is presented. In this methodology, the source and target databases are described in terms of the association types of a semantic association model. The structural properties, the integrity constraints, and the operational characteristics (storage operation behaviors) of the association types are more explicitly defined to reveal the semantics that is generally hidden in application programs. The explicit descriptions of the source and target databases are used as the basis for program analysis and conversion. Application programs are described in terms of a small number of "access patterns" which defme the data traversals and operations of the programs. In addition to the methodology, this paper (1) describes a model of a generalized application program conversion system that serves as a framework for research, (2) presents an analysis of access patterns that serve as the primitives for program description, (3) delineates some meaningful semantic changes to databases and their corresponding transformation rules for program conversion, (4) illustrates the application of these rules to two different approaches to program conversion problems, and (5) reports on the development effort undertaken at the University of Florida.
