Architectural descriptions are built from 'i-specs' that define interface-level interaction patterns. An i-spec can be seen as a contract defining the rights and obligations of 'roles' that can be played in interface-based interactions. We introduce the 'closed world assumption' for i-specs, leading to a compositional approach to defining software architectures. We show how i-specs can be composed and how component specifications can be constructed from i-specs.","PeriodicalId":339670,"journal":{"name":"Proceedings Working IEEE/IFIP Conference on Software Architecture","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125388776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is shown how the specialization interface (\"hot spots\") of a framework can be annotated with specialization patterns to provide task-based guidance for the framework specialization process. The specialization patterns define various structural, semantic, and coding constraints over the applications derived from the framework. We also present a tool that supports both the framework development process and the framework specialization process, based on the notion of specialization patterns. We outline the basic concepts of the tool and discuss techniques to identify and specify specialization patterns as required by the tool. These techniques have been applied in realistic case studies for creating programming environments for application frameworks.","PeriodicalId":339670,"journal":{"name":"Proceedings Working IEEE/IFIP Conference on Software Architecture","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132760242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since networked workstations are readily available in most organizations, they provide an economic and scalable alternative to parallel machines. The authors discuss how individual nodes in a computer network can be used as a collection of connected processing elements to improve the performance of a software engineering tool that we developed. Our tool, called Bunch, automatically clusters the structure of software systems into a hierarchy of subsystems. Clustering helps developers understand complex systems by providing them with high-level abstract (clustered) views of the software structure. The algorithms used by Bunch are computationally intensive and, hence, we would like to improve our tool's performance in order to cluster very large systems. The paper describes how we designed and implemented a distributed version of Bunch, which is useful for clustering large systems.","PeriodicalId":339670,"journal":{"name":"Proceedings Working IEEE/IFIP Conference on Software Architecture","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116957437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is widely perceived that the OO approach, despite its generally acknowledged strengths, has so far failed to fully deliver its promises. Based on experiences from the development of several large embedded SW systems, an analysis of common practical and conceptual problems in OO SW development is performed and a solution is suggested The analysis indicates a need for SW architecture as a separate concept. The discussion of the solution concentrates on the nature of SW architecture in this context, on the methodological implications of combining SW architecture work with OO approach and on the role of the architecture task in the entirety of SW construction.","PeriodicalId":339670,"journal":{"name":"Proceedings Working IEEE/IFIP Conference on Software Architecture","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128563147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For better performance, it is important to keep resources and information integrity from unexpected use by unauthorized users. Therefore, there is a strong demand for access control of distributed shared resources. Role-Based-Access-Control (RBAC) has been introduced and offers a powerful means for specifying access control decisions. The authors propose an object oriented RBAC model for distributed system (ORBAC), it efficiently represents the real world. Moreover, under the decentralized ORBAC management architecture, an implementation of the model has realized multiple-domain access control. Finally, statically and dynamically role authorization is considered and a method to deal with the problem of separation of duties is presented.","PeriodicalId":339670,"journal":{"name":"Proceedings Working IEEE/IFIP Conference on Software Architecture","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130143758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Architecture Description Languages (ADLs) form a foundation for modeling and analyzing functional and non-functional properties of software systems, but, short of programming, only the simulation of those models can ensure certain desired qualities and functionalities. The paper presents an adaptation to statechart simulation, as pioneered by D. Harel (1987). This extension supports architectural dynamism: the creation, replacement, and destruction of components. We distinguish between design-time dynamism, where system dynamics are statically proscribed (e.g., creation of a predefined component class in response to a trigger), and run-time dynamism, where the system is modified while it is running (e.g., replacement of a faulty component without shutting down the system). Our enhanced simulation language, with over 100 commands, is tool-supported.","PeriodicalId":339670,"journal":{"name":"Proceedings Working IEEE/IFIP Conference on Software Architecture","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124494583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to evaluate the potential of creating a product line from existing products, it is necessary to 'mine' their architectures and analyze the commonalities and variabilities across those architectures. To manage the evaluation process in a disciplined way the paper introduces the MAP (Mining Architectures for Product Lines) method. MAP outlines a bottom-up approach for mining the architecture of the existing products, a top-down approach to mapping architectural styles and attributes onto the mined architectures and an approach to analyzing their commonalities and variabilities. It combines well-known architecture reconstruction and product line analysis techniques. A case study is presented showing the application of the method and its benefits are outlined.","PeriodicalId":339670,"journal":{"name":"Proceedings Working IEEE/IFIP Conference on Software Architecture","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114384888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper argues that the problems we face exist because our understanding is based on specious analogies with traditionally engineered artefacts.

A detailed examination is then presented of the differences that exist between the nature of the systems, the content of their large-scale representations, and how they are used in practice in the respective disciplines. These differences seriously undermine the analogies used to develop our understanding and this is discussed in terms of software engineering as a whole.","PeriodicalId":339670,"journal":{"name":"Proceedings Working IEEE/IFIP Conference on Software Architecture","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130893606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
