The number of open source database management systems (DBMS) currently available leave a potential user with the difficult decision of choosing the appropriate system that suits his particular requirements. This paper describes a software platform that allows a potential open source database management system user to carry out a performance evaluation on various open source relational database ...

Monitoring network performance and status is a fundamental task for network operators as it directly impacts the quality of the offered services and hence user satisfaction. For this purpose a consolidated approach, which is largely adopted by network operators, is based on the so-called KPIs (key performance indicators). In this paper, we propose and discuss a set of KPIs to monitor network pe...

Aspect-Oriented Programming (AOP) was proposed with the main objective of addressing an important software quality principle that is modularization. The basic idea of the paradigm is to capture crosscutting concerns as a programming abstraction called aspect. Since the introduction of aspects as a complement to objectoriented programming, many evaluations and empirical studies were provided to ...

Static analysis is an efficient approach for software assurance. It is indicated that the most effective usage of it is to perform analysis in an interactive way through software development process, which has a high performance requirement. This paper concentrates on rule-based static analysis tools and proposes an optimized rule-checking algorithm to improve their performance. Our technique f...

This paper discusses software performability evaluation considering the real-time property. We assume that the software system has two operational states from the viewpoint of the end users: one is operating with the desirable performance level according to specification and the other is with degraded performance level. The time-dependent behavior of the system is described by the Markovian sof...
