Despite their advantages, industrial software developers are reluctant to adopt these methods due to the lack of tools for constructing generators. This paper presents a framework for the development of application generators. This framework provides a structured design approach and automatic tools for design. The framework consists of a two level design process: The first level is the identification of operations that expresses the fundamental computations of the application domain. The second level is the design of a domain-specific language which allows one to express variations within a family of applications. The domain-specific language is implemented in terms of the operations defined by the first level. We show that the uniform application of partial evaluation enables automatic application generation from a micro-program to its implementation. This framework has been developed in the context of real applications in areas such as Internet services and digital television, and is being developed in conjunction with industrial partners.","PeriodicalId":270366,"journal":{"name":"ACM SIGSOFT Symposium on Software Reusability","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130275838","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 this paper, we focus on reusable software component retrieval methods that were developed and teated in the context of ClassServer, an experimental library tool developed at the University of Qu6bec at Montr6al to explore fssues in software reuse [15]. The methods dfscusaed in tbfa paper fall into two categori~ 1) string search-based retrieval metbod$ and 2) keyword-based retrieval methods. Both kinds of methods have been implemented and tested by researchers, both in the context of software repositories (see e.g. [6,9]) and in the context of more traditional document tibrarles (see e.g. [2,25]). Experiments have shown that keyword-based methods, which require some manual, laborintensive pre-proceashrg, performed only marginally better than the entfrely mechanical strhtgsearch methods (see e.g.[6, 2S]), raising the issue of cost-effectivene= of keyword-based methods as compared to string search baaed methods. In this paper, we describe an implementation and experiments which attempt to brfng the two khtds of methods to a level-playing field by: 1) automating as much of the pre-processing involved hr controlled vocabulary-based methods as possible to address the crds issue, and 2) using a realistic experimental setting in which queries consist of problem statemenlx rather than component specifications, in whjch query results are aggregated over several trials, and in which recaU measures take into account overlapping components. Our experiments showed that string search based methods performed better than semi-controlled vocabulary-based method$ which goes further in the direction of more recent component retrfeval experiments which challenged the superiority of controlled vocabulary based clarification and retrieval of components (see e.g. [61).","PeriodicalId":270366,"journal":{"name":"ACM SIGSOFT Symposium on Software Reusability","volume":"23 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128181903","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}

Some of these products, such as an Airborne Warning and Control System (AWACS) or an inertial Upper Stage (lUS), exist as long-lived (20+ years) product lines that are more like legacy systems under continuous maintenance than true product lines. Also, the business climate for U.S. aerospace companies over the past several years has stimulated Boeing DdWG to look for ways to reduce system development costs and improve the quality factors for the products it deiivers. Systematic reuse, with its emphasis on domains, competencies, product lines, and architectures is viewed as an enabling technology for achieving those goals. To understand and test application of these concepts, Boeing D&SG kicked off a Hardware and Software Reuse Initiative in August of 1995. As the name implies, ~heD&SG Reuse Initiative must jind ways to apply systematic reuse thattreat hardware and sojlware issues together. Part of the reason for this challenge is that the majority of products that D&SG delivers have signljicant functionality being provided via electronic, electro-optical, or electro-mechanical devices. Another part of the reason is thatD&SG emphasizes “systems thinking” during product development. The point of intersection of hardware and sojiware where systematic reuse perhaps has the greatest leverage is architecture. Therefore, an internal research and development activity under the auspices of the D&SG Reuse Initiative was kicked off in September of 1995 to spec.ijically address architecture issues. One of the jirst observations emerging from this activity was that the lack of Urrforrnip among the vars”ous D&SG groups in descriptions of architecture signt~cantly impedes exchange of technical architecture data and knowledge across groups. This paper discusses an approach to architecture description devised specifically to alleviate that problem in the hope of creating a climate for reuse of open, commercial off-the shelf (COTS) based architectures.","PeriodicalId":270366,"journal":{"name":"ACM SIGSOFT Symposium on Software Reusability","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132368461","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}
