The approach is safe because it enforces appropriate type compatibility across language boundaries. It is transparent since it shields software developers from the details inherent in low-level language-based interoperability mechanisms. It is lightweight for developers because it eliminates tedious and error-prone coding (e.g., JNI) and lightweight at run-time since it does not unnecessarily incur the performance overhead of distributed, IDL-based approaches. The Exu approach exploits and extends the object-oriented concept of meta-object, encapsulating interoperability implementation in meta-classes so that developers can produce interoperating code by simply using meta-inheritance. An example application of Exu to the development of Java/C++ (i.e., multilanguage) programs illustrates the safety and transparency advantages of the approach. Comparing the performance of the Java/C++ programs produced by Exu to the same set of programs developed using IDL-based approaches provides preliminary evidence of the performance advantages of Exu.","PeriodicalId":269568,"journal":{"name":"25th Annual International Computer Software and Applications Conference.

The successes and problems associated with each are highlighted. Details are presented of a project supported by the International Federation of Information Processing, concerned with the harmonisation of professional standards, which could now be very relevant to re-establishing progress on the road to a SE profession. Efforts undertaken to promote this work to the SE community are also reported. Finally overall conclusions and recommendations are given that could improve the situation in the future.","PeriodicalId":269568,"journal":{"name":"25th Annual International Computer Software and Applications Conference.

The method is entirely derivable (after a formal verification) into rules integrated into a cooperative architecture allowing the cooperation.

Performance is essentially determined by the load on the site at peak time under varying conditions. Typically, performance testing is conducted in a simulated environment using tools. However, performance as perceived by the user is most critical since the user is the ultimate judge for the success of the web site. Although the complexity of web sites makes it difficult to draw a common denominator for user perception and designer viewpoint, it is necessary to modulate user perceptions to aid robust web site design. This paper proposes a new model, PePPeR, which enforces incorporation of user perceptions in the design process. Using this model, the designer can consider the projected perceptions during performance testing without diluting application reliability. The model is substantiated through a detailed case study with empirical results.","PeriodicalId":269568,"journal":{"name":"25th Annual International Computer Software and Applications Conference.

Database application programs typically contain statements written in an imperative programming language with embedded data manipulation commands, such as SQL. However relatively little study has been made in the testing of database application programs. In particular, few testing techniques explicitly consider the inclusion of database instances in the selection of test cases and the generation of test data input. In this paper, we study the generation of database instances that respect the semantics of SQL statements embedded in a database application program. The paper also describes a supporting tool which generates a set of constraints. These constraints collectively represent a property against which the program is tested. Database instances for program testing can be derived by solving the set of constraints using existing constraint solvers.","PeriodicalId":269568,"journal":{"name":"25th Annual International Computer Software and Applications Conference.

For large projects, requirements negotiation can be especially difficult to do effectively and efficiently when combining input from non-co-located experts and reaching consensus among the different stakeholders (e.g., end-users, developers, software assurance, customers) as well as among the different aspects of software requirements (e.g., functionality, non-functional quality, and infrastructure). Stakeholder perception conflicts about requirements issues should be identified and resolved in early stage of the project life-cycle to achieve a shared vision of the requirements. A technique for effective and efficient requirements conflict identification and resolution is needed. In this paper, we discuss the issues of applying visualization technique to requirements conflict identification and resolution problems with exploration of potential solution approaches. The following visualization issues are discussed: (1) stakeholders' perception representation and consensus measurement, (2) perception visualization, (3) conflict identification, and (4) conflict resolution.","PeriodicalId":269568,"journal":{"name":"25th Annual International Computer Software and Applications Conference.

This is, however, a misconception. This paper argues that, in order to reflect the functional requirements, a role hierarchy becomes very complex. In a bid to simplify the design of role hierarchies suitable for the expression of access control requirements in workflow systems, the paper proposes a \"typed\" role hierarchy. In a \"typed\" role hierarchy a role is of a specific type. The associations between different types of roles are limited by rules that govern the construction of a role hierarchy. This paper proposes a methodology to systematically construct a \"typed\" role hierarchy. Since the \"typed\" nature of the role hierarchy is only relevant during the construction of the role hierarchy, it can seamlessly be integrated into existing RBAC schemes that support the concept of role hierarchies.","PeriodicalId":269568,"journal":{"name":"25th Annual International Computer Software and Applications Conference.

A design pattern is a structural unit in a system built out of patterns, not unlike the way a function is a structural unit in a procedural program or a class is a structural unit in an OO system designed without patterns. When designers treat patterns as structural units, they become concerned with issues such as coupling and cohesion at a new level of abstraction. We examine the notion of pattern coupling to classify how designs may include coupled patterns. We find many examples of coupled patterns; this coupling may be \"tight\" or \"loose\", and provides both benefits and costs. We qualitatively assess the goodness of pattern coupling in terms of effects on maintainability, factorability, and reusability when patterns are coupled in various ways.","PeriodicalId":269568,"journal":{"name":"25th Annual International Computer Software and Applications Conference.

This paper proposes an approach to design End-to-End (E2E) integration testing, including test scenario specification, test case generation and tool support. Test scenarios are specified as thin threads, each of which represents a single function from an end user's point of view. Thin threads can be organized hierarchically into a tree with each branch consisting of a set of related thin threads representing a set of related functionality. A test engineer can use thin-thread trees to generate test cases systematically, as well as carry out other related tasks such as risk analysis and assignment, regression testing, ripple effect analysis. A prototype tool has been developed to support E2E testing in a distributed environment on the J2EE platform.","PeriodicalId":269568,"journal":{"name":"25th Annual International Computer Software and Applications Conference.
