A methodology for integrating legacy systems with the client/server environmentRedelinghuys, Melinda 06 1900 (has links)
The research is conducted in the area of software methodologies with the emphasis on the integration of legacy systems with the client/server environment. The investigation starts with identifying the characteristics of legacy systems in order to determine the features and technical characteristics required of an integration methodology. A number of existing methodologies are evaluated with respect to their features and technical characteristics in order to derive a synthesis for a generic methodology. This evaluation yields the meta primitives of a generic
methodology. The revised spiral model (Boehm,1986; DuPlessis & Vander Wah,1992) is customised to
arrive at a software process model which provides a framework for the integration of legacy systems
with the client/server environment. The integration methodology is based on this process model. / Computing / M. Sc. (Information Systems)

From specification through refinement to implementation : a comparative studyVan Coppenhagen, Ingrid H. M. 30 June 2002 (has links)
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. / Computing / M. Sc. (Information Systems)

Coping with evolution in information systems: a database perspectiveLawrence, Gregory 25 August 2009 (has links)
Business organisations today are faced with the complex problem of dealing with
evolution in their software information systems. This effectively concerns the
accommodation and facilitation of change, in terms of both changing user
requirements and changing technological requirements. An approach that uses the
software development life-cycle as a vehicle to study the problem of evolution is
adopted. This involves the stages of requirements analysis, system specification,
design, implementation, and finally operation and maintenance. The problem of
evolution is one requiring proactive as well as reactive solutions for any given
application domain. Measuring evolvability in conceptual models and the
specification of changing requirements are considered. However, even "best designs"
are limited in dealing with unanticipated evolution, and require implementation phase
paradigms that can facilitate an evolution correctly (semantic integrity), efficiently
(minimal disruption of services) and consistently (all affected parts are consistent
following the change). These are also discussed / Computing / M. Sc. (Information Systems)

Electronic data interchange : an implementation methodologyMeyer, Ettienne 11 1900 (has links)
The purpose of the research is to propose and evaluate a
methodology for implementing EDI to assist organisations in
reaping the anticipated benefits. The research involved the
systematic analysis of the state of the art of EDI and
paradigms of methodologies, to define a model for the EDI
implementation methodology, and to define criteria for
evaluating such a model. The methodology was developed and
modelled utilising the software process model, as adopted by
Boehm (1988) and later duPlessis and van der Walt (1992),
as a framework. Next a synthesis of the assimilated
knowledge and brainstorming of project teams involved in
EDI pilot projects, was used to systematically develop an EDI
implementation methodology. The methodology was evaluated
by utilising it in the implementation of EDI between two
organisations, Computer Equipment Brokers (PTY) and
Marksec (PTY). It was concluded that the methodology was
efficient for implementing EDI. / Computing / M. Sc. (Information Systems)

Integration testing of object-oriented softwareSkelton, Gordon William 08 1900 (has links)
This thesis examines integration testing of object-oriented software. The process of integrating and testing procedural programs is reviewed as foundation for testing object-oriented software. The complexity of object-oriented software is examined. The relationship of integration testing and the software development life cycle is presented. Scenarios are discussed which account for the introduction of defects into the software. The Unified Modeling Language (UML) is chosen for representing pre-implementation and post-implementation models of the software. A demonstration of the technique of using post-implementation models representing the logical and physical views as an aid in integration and system testing of the software is presented. The use of UML diagrams developed from the software is suggested as a technique for integration testing of object-oriented software. The need for automating the data collection and model building is recognized. The technique is integrated into the Revised Spiral Model for Object-Oriented Software Development developed by du Plessis and van der Walt. / Computing / D.Phil. (Computer Science)

Knowledge-based support for object-oriented designLoock, Marianne 06 1900 (has links)
The research is conducted in the area of Software Engineering, with emphasis on the design phase of the Software Development Life Cycle (SDLC). The object-oriented paradigm is the point of departure. The investigation deals with the problem of creating support for the design phase of object-oriented system
development. This support must be able to guide the system designer through the design process, according to a sound design method, highlight opportunities for prototyping and point out where to re-iterate a design step, for example. A solution is proposed in the form of a knowledge-based support system. In the prototype this support guides a designer partially through the first step of the System Design task for object-oriented design. The intention is that the knowledge-based system should capture the know-how of an expert system designer and assist an inexperienced system designer to create good designs. / Computing / M. Sc.
