1. Renaud, Karen Vera. A comparative study of transaction management services in multidatabase heterogeneous systems.

Degree: 1996, University of South Africa

Multidatabases are being actively researched as a relatively new area in which many aspects are not yet fully understood. This area of transaction management in multidatabase systems still has many unresolved problems. The problem areas which this dissertation addresses are classification of multidatabase systems, global concurrency control, correctness criterion in a multidatabase environment, global deadlock detection, atomic commitment and crash recovery. A core group of research addressing these problems was identified and studied. The dissertation contributes to the multidatabase transaction management topic by introducing an alternative classification method for such multiple database systems; assessing existing research into transaction management schemes and based on this assessment, proposes a transaction processing model founded on the optimal properties of transaction management identified during the course of this research. Advisors/Committee Members: Kotze, Paula, 1956- (advisor).

Subjects/Keywords: Multidatabase; Recovery; Reliability; Autonomy; Heterogeneity; Distribution; Concurrency control; Atomic transaction; Transaction; Serializability; Global serialization; Global transaction atomicity; Global deadlock; Two-phase commit protocol; Compensation; Recoverability; Strictness

2. De Villiers, M.R. (Ruth). Integrating a software engineering approach and instructional factors in instructional software development – illustrated by a prototype in theoretical computer science.

Degree: 1995, University of South Africa

This dissertation is a multi-disciplinary study, which integrates a software engineering approach with instructional factors in the decision-making, analysis, design and development processes of instructional software. Software engineering models, tools and representations are used in the process of software construction. With reference to the fundamental characteristics of the software product, several disciplines and factors, from both instructional and computing perspectives are considered, and the most appropriate approach/es selected. Software engineering, instructional design and instructional theory are considered as pillars of courseware engineering. The object-oriented design paradigm and a prototyping life-cycle model are found to be most suitable for development of computer-aided instruction. The conceptual study is illustrated by prototype development of a component-based multi-activity practice environment in theoretical Computer Science. It offers perusal or practice, in various instructional modes, according to the user's preferred learning style or need. Advisors/Committee Members: Kotze, Paula, 1956- (advisor).

Subjects/Keywords: Cognitive science; Component-based software; Computer-aided instruction; Courseware engineering; Instructional design; Instructional systems development; Instructional theory; Instructional transactions; Object-oriented design; Practice environment; Prototyping; Software engineering

3. Van Coppenhagen, Ingrid H. M. From specification through refinement to implementation : a comparative study .

Degree: 2002, University of South Africa

This dissertation investigates the role of specification, refinement and implementation in the software development cycle. Both the structured and object-oriented paradigms are looked at. Particular emphasis is placed on the role of the refinement process. The requirements for the product (system) are determined, the specifications are drawn up, the product is designed, specified, implemented and tested. The stage between the (formal) specification of the system and the implementation of the system is the refinement stage. The refinement process consists out of data refinement, operation refinement, and operation decomposition. In this dissertation, Z, Object-Z and UML (Unified Modelling Language) are used as specification languages and C, C++, Cobol and Object-Oriented Cobol are used as implementation languages. As an illustration a small system, The ITEM System, is specified in Z and UML and implemented in Object-Oriented Cobol. Advisors/Committee Members: Van der Poll, John Andrew (advisor), Kotze, Paula, 1956- (advisor).

Subjects/Keywords: Specification; Refinement; Implementation; Data refinement; Operation refinement; Operation decomposition; UML; Z; Object-Z; C; C++; Cobol; Object-Oriented Cobol; Software development life cycle; Structured; Object-oriented; Class; Object; Schema; Inheritence; Verification; Validation; Axiomatic description
