In this paper, we introduce an approach to providing impact analysis and change propagation support as an integral part of software engineering environments, so that they can be applied during both software development and maintenance. In this approach, the activities are carried out on the original representation of software artifacts in the environment, rather than on a separate system model extracted. This very fact enables automated direct support for the process of actually carrying out and propagating the changes. Dependences and properties of software artifacts are used for impact analysis to achieve increased flexibility and expressiveness. Both impact analysis and change propagation are a combination of guided user intervention and automatic processing based on codified change patterns and propagation rules.","PeriodicalId":68622,"journal":{"name":"软件","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1997-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84823092","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}

This framework recognises levels of abstraction, which is not the same as levels of detail, in the systems development process. If the model-driven approach is applied in addition to object oriented analysis concepts, significant benefits are to be expected on the side of maintenance cost. Indeed, one of the main benefits of the model-driven development process is the perfect modular structure of the developed systems. This facilitates maintenance dramatically. However, in order to prove such a statement it is necessary to wait until sufficient experience is gained in the maintenance of systems developed according to this approach. M.E.R.O.DE. is an object oriented development based on two principles: model-driven development and specification by contract. The method was developed around 1988 and has been used by customers since 1991. The paper presents the result of a small scale and informal inquiry amongst the M.E.R.O.DE, users. As many systems they developed have been subject of maintenance, their experiences should allow one to asses or reject the hypothesis that model-driven development facilitates maintenance dramatically. Although the results presented pertain to one particular method, the model-driven approach can be adopted by users of any object oriented analysis method.","PeriodicalId":68622,"journal":{"name":"软件","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1997-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73764060","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 model is expressed in LOTOS and provides a precise and unambiguous formal requirements specification of the static, dynamic and functional aspects of a problem. There is, however, a wide gap between informal requirements and a formal specification. To help bridge this gap, the authors propose that a formal and executable model which specifies behaviour in terms of what the environment expects from the system should be constructed initially. This user-centred model will give very early feedback to the requirements capture process and can be used as a step in the construction of the ROOA model. Both models are expressed in the same executable formal language and so they can be composed to verify that the ROOA model is compatible with the user-centred model and the composition executed to validate it with respect to the requirements.","PeriodicalId":68622,"journal":{"name":"软件","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1997-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88923486","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}

This paper introduces our approach to combining transformation and semantic interface analysis for reuse of COBOL programs. In our approach, COBOL programs are reverse engineered to their designs represented in entity-relationship (ER) diagrams. Both the original code and obtained ER diagrams are used by semantic interface analysis. Reusable components are annotated with conditions which are needed for checking suitability and are saved in a reuse library for reuse and reengineering. Our method is demonstrated in detail through an example in this paper. Besides being practical, the advantages of the approach include the fact that a formal link between the original COBOL program and its design in an ER diagram form is retained, and both the program code and the design can be reused.","PeriodicalId":68622,"journal":{"name":"软件","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1997-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81297594","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}
