Configuration tool for component-based real-time databases

ID: LiTH-IDA-Ex-05/003--SE

Aspectual component-based system development (ACCORD) is a method for development of real-time system that enables a system to be developed out of software components and aspects. This way, the system is developed with low development costs and a high degree of configurability. Within ACCORD, techniques have been developed for analysis of composed real-time systems with respect to worst-case execution time and memory footprint. ACCORD has been applied on the development of a configurable component-based real-time embedded database system, denoted COMET. The COMET library consists of a number of components and aspects that can be combined to form different COMET database configurations, depending on the requirements on the real-time system. In this thesis we have developed a tool framework that provides a real-time system designer with support for configuration of a system out of software components and aspects. Hence, the tool framework represents an environment for modeling and analysis of ACCORD-based systems. Within the framework we have made a specific instance of the tool for configuration and analysis of the COMET database. Two plug-ins have been developed within the tool framework. One of the plug-ins denoted the configurator, gives the designer support in suggesting a subset of aspects and components based on the requirements. Another plug-in, denoted the M&W analyzer, helps designer to perform either worst case execution time or memory footprint analysis on the configuration he/she makes.

Keywords: real-time database system, worst case execution time, generic modeling environment,components, aspects
