4th International Workshop on Information Systems in Distributed Environment Graz, Austria, 13th September 2013
• Methodology for adapting component-based software systems at runtime
• Architectural models in two levels: – Abstract (PIM perspertive) – Concrete (PSM perspective)
• Resolve PSM models from PIM definition at runtime • Using a trading process for realizing the concrete architectural
models (PSM) in six stages: – Selection of candidate components – Calculation of configurations – Closure of configurations – Calculation of compliant configurations – Application of heuristics – Building the concrete architectural model
Conclusions
![Page 48: Resolving Platform Specific Models at runtime using an MDE-based Trading approach](https://reader035.vdocuments.net/reader035/viewer/2022081404/55849036d8b42a043a8b505b/html5/thumbnails/48.jpg)
4th International Workshop on Information Systems in Distributed Environment Graz, Austria, 13th September 2013
• Generates the configuration of concrete components that best meets the abstract definition
• Provides the possibility of generating different configurations of sofware architectures based on the same abstract definition
• Uses information about the meaning given by the functional and non-functional properties of the components: Semantic Trader
Conclusions
![Page 49: Resolving Platform Specific Models at runtime using an MDE-based Trading approach](https://reader035.vdocuments.net/reader035/viewer/2022081404/55849036d8b42a043a8b505b/html5/thumbnails/49.jpg)
4th International Workshop on Information Systems in Distributed Environment Graz, Austria, 13th September 2013
Future Work
• We assume that at least one valid configuration will be resolved
• Alternative resolution mechanism if there is not resolved a valid configuration
• Resolution of mismatches (e.g. incompatibilies of components)
• Implement searching algorithms (calculation of configurations) based on heuristics to perform tree pruning
