Information modeling methodologies and techniques
Title
Information modeling methodologies and techniques.
Creator
Djaja, Eddy Winata., Florida Atlantic University, Solomon, Martin K.
Abstract/Description
We survey and critically compare various approaches and software products for the modeling and logical design of relational databases. In particular, we examine different information modeling methodologies, such as Information Engineering, CASE$\sp*$Method, the Three Schema Concept, as well as data modeling techniques, such as the Entity-Relationship techniques, and the Object Role Modeling technique.

Approaches to object/relational database systems
Title
Approaches to object/relational database systems.
Creator
Vijayanagaram, Hemanth Kumar., Florida Atlantic University, Solomon, Martin K., Larrondo-Petrie, Maria M., College of Engineering and Computer Science, Department of Computer and Electrical Engineering and Computer Science
Abstract/Description
In this thesis, we investigate the different proposed ways of combining object oriented and relational database systems (such combined systems are commonly called object-relational systems). This thesis is based on ideas presented in various papers about object and object relational databases. In this work, a discussion of standards such as ANSI's SQL3 (to be released) and ODMG-93 is given. In particular, the "Class = Relation" and "Class = Domain" approaches to object-relational systems are...

This thesis is based on ideas presented in various papers about object and object relational databases. In this work, a discussion of standards such as ANSI's SQL3 (to be released) and ODMG-93 is given. In particular, the "Class = Relation" and "Class = Domain" approaches to object-relational systems are investigated. Arguments supporting the proposition that the latter approach is the correct approach are presented.

A relational algebra implementation
Title
A relational algebra implementation.
Creator
Rivero, Gene Richard., Florida Atlantic University, Solomon, Martin K.
Abstract/Description
Although the Relational Algebra (RA) is a fundamental component of the relational model of database storage and retrieval, it has not been widely implemented in commercial database systems. The Structured Query Language (SQL) has been for some time the most widely implemented relational database language. This thesis provides and describes the first implementation of a particularly powerful version of the relational algebra that includes an n-ary join operator as well as including the...
Show moreAlthough the Relational Algebra (RA) is a fundamental component of the relational model of database storage and retrieval, it has not been widely implemented in commercial database systems. The Structured Query Language (SQL) has been for some time the most widely implemented relational database language. This thesis provides and describes the first implementation of a particularly powerful version of the relational algebra that includes an n-ary join operator as well as including the division operator, and nested expressions. With this implementation, that powerful version of the relational algebra can be used as a front end to any SQL-92 compliant database management system, such as Oracle, Informix, DB2, Sybase, SQL Server, and Access.

evolution and extension of PEIRCE RDBMS
Title
The evolution and extension of PEIRCE RDBMS.
Creator
Hard, Bruce W., Florida Atlantic University, Solomon, Martin K.
Abstract/Description
In 1981, Dr, Martin K. Solomon and Carl D. Kirshen published the paper, "PEIRCE: A Relational DBMS for Small Systems," that utilized Codd's relational algebra as a basis for this interactive database management system. Looking back, it is easy to see that PEIRCE was ahead of its time in many ways, especially by showing an early understanding of the relationship of triggers and virtual files, and recognizing the need for a user interface, known as the Clerk Oriented Interface.

Looking back, it is easy to see that PEIRCE was ahead of its time in many ways, especially by showing an early understanding of the relationship of triggers and virtual files, and recognizing the need for a user interface, known as the Clerk Oriented Interface. An historical overview of PEIRCE will be given, along with a comparison of PEIRCE to the ever popular state-of-the-art ORACLE relational database management system, as well as an explanation of my new extensions to the subsystems of the PEIRCE DBMS. The historical overview is useful because it covers the evolution of PEIRCE over a period of more than 15 years, and collects the previously disjoint information into one place. Also, this overview is interesting because it reflects the change in database and computer technology over that time.

Reducing impedance mismatch in SQL embeddings for object-oriented programming languages
Title
Reducing impedance mismatch in SQL embeddings for object-oriented programming languages.
Creator
Hurtado, Jose Luis, College of Engineering and Computer Science, Department of Computer and Electrical Engineering and Computer Science
Abstract/Description
We survey and compare the different major mechanisms for embedding the relational database language SQL in object-oriented programming languages such as Java and C#, with regard to how much impedance mismatch these embeddings suffer. Here impedance mismatch refers to clarity and performance difficulties that arise because of the nature of the embedding.

Show moreWe survey and compare the different major mechanisms for embedding the relational database language SQL in object-oriented programming languages such as Java and C#, with regard to how much impedance mismatch these embeddings suffer. Here impedance mismatch refers to clarity and performance difficulties that arise because of the nature of the embedding. Because of the central position in the information technology industry of object-oriented programs that access SQL-based relational database systems, reducing impedance mismatch is generally recognized in that industry as an important practical problem. We argue for the suitability of SQL as a database language, and hence for the desirability of keeping SQL as the view provided by a SQL embedding. We make the case that SQLJ, a SQL embedding for Java in which it appears that Java directly supports SQL commands, is the kind of SQL embedding that suffers the least impedance mismatch, when compared with call-level interfaces and object-relational mappings. We propose extensions to SQLJ that would reduce its impedance mismatch even further.

Approaches to relational database access from object-oriented programming languages
Title
Approaches to relational database access from object-oriented programming languages.
Creator
Ghouse, Murtuza., Florida Atlantic University, Solomon, Martin K.
Abstract/Description
In this thesis, different methods to access relational databases from an object oriented programming language like Java have been investigated. The approaches that are covered are JDBC (Java Database Connectivity), SQLJ (industry standard for embedding SQL in Java) and Java Blend (product from Sun Microsystems, that provides object-oriented way to access data in a relational database). The emphasis is given to Java Blend, as it is a new tool with a very broad scope. And arguments in support...
