A Domain-Specific Modeling Approach This study has presented a component-based domain modeling approach that provides an environment for simplifying and accelerating software development and analysis, and improves software reusability, maintainability, and productivity. With highlevel design abstraction, constraints of application domains, and the guidance of domain rules, the proposed component-based framework offers an effective solution to modeling and automating the development and deployment of software application. Meta-modeling will be used in this study to define the domain notations, rules, and constraints for component composition within a specific domain context. A domain-specific graphical design environment will also be proposed to simplify and accelerate the software development by simply dragging and dropping pre-built components with minimal programming effort. The modeling of components can be further extended with the specification of their dependability and real-time constraints. / Related work -- Component composition -- Domain-specific modeling -- Model-based component composition environment for a specific domain -- Mobile service creation framework (MCSF) -- A model-driven approach to implementing dependable component-based mobile services -- A model-driven approach to implementing component-based real-time mobile services / Related work -- Component composition -- Domain-specific modeling -- Model-based component composition environment for a specific domain -- Mobile service creation framework (MCSF) -- A model-driven approach to implementing dependable component-based mobile services -- A model-driven approach to implementing component-based real-time mobile services. / Department of Computer Science
