What is the point of improving maintenance processes if the most important asset, people, is not properly utilised? Knowledge of the product(s) maintained, maintenance processes and communications skills is very important for achieving quality software and for improving maintenan…
This paper describes two software maintenance support tools, CCFinder (Code Clone Finder) and JAAT (Java Alias Analysis Tool), for Java programs. CCFinder identifies code clones in Java programs, while JAAT executes alias analysis for Java programs.
Potential advantages brought about by distributed system architectures has given rise to the number of applications being based around it. Advantages include an increase in fault tolerance due to replicated components and achieving cost effective scalability by distributing the e…
The benefits of a software system are assessable only relative to the business goals the system has been developed to serve. In turn, these benefits result from interactions between the system's functionality and its quality attributes (such as performance, reliability and securi…
Today's Web services not only have to be flexible, but also have to be device independent to support mobile devices such as WAP and PDAs. Supporting multiple Web formats (e.g., WML, HTML, etc.) is still an open challenge. Most sites have to provide a separate application for ever…

The Unified Modeling Language (UML) provides several diagram types, viewing a system from different perspectives. In this research, we exploit the logical relationships between different UML models. We propose operations to compare, merge, slice and synthesize UML diagrams based …
There are two basic parts to the behavioral specification of distributed systems: safety and progress. In earlier work, we developed a tool to monitor progress properties of CORBA components specified using the temporal operator transient. In this paper, we address the specificat…
XML is emerging as an important format for describing the schema of documents and data to facilitate integration of applications in a variety of industry domains. An important issue that naturally arises is the requirement to generate, store and access XML documents. It is import…
A good object oriented design does not necessarily make a good component based design, and vice versa. What design principles do components introduce? The paper examines component based programming and how it expands the design space in the context of an event based component arc…
The Minimally Adequate Synthesizer (MAS) is an interactive algorithm that synthesizes UML statechart diagrams from sequence diagrams. It follows D. Angluin's (1987) framework of a minimally adequate teacher to infer the desired statechart diagram by consulting the user. To minimi…
Focuses on investigating the combined use of semantic and structural information of programs to support the comprehension tasks involved in the maintenance and reengineering of software systems. "Semantic information" refers to the domain-specific issues (both the problem and the…
The proliferation of wireless networks and small portable computing devices raises the need for applications that are adaptable to heterogeneous computing and communication environments and the contexts in which they are used. However, most current groupware systems as well as ot…
Informal and graphical modeling techniques enable developers to construct abstract representations of systems. Object-oriented modeling techniques further facilitate the development process. The Unified Modeling Language (UML), an object-oriented modeling approach, could be broad…
This dissertation explores the relationships between feature engineering, CBSE, and software evolution. Software end-users and developers have different perspectives of a software system, resulting in a complexity gap between user expectations and the software functionality. This…
Early testing of requirements can decrease the cost of removing errors in software projects. However unless done carefully, that testing process can significantly add to the cost of requirements analysis. We show that requirements expressed as topoi diagrams can be built and test…
Developers learn to use a software library not just from its documentation but also from toy examples and existing real-life application code (e.g. by using grep). The CodeWeb tool takes this simple idea further by a deeper analysis of a large collection of applications to see wh…
