It will formally derive programs using the paradigm of program transformation. The following issues are discussed: (1) the integration of validation and program derivation activities in the Focus system; (2) its tree-based user interface; (3) the control of search spaces in program derivation; and (4) the structure and organization of program derivation records. The inference procedures of the system are based on the integration of functional and logic programming principles. This brings about a synthesis of paradigms that were heretofore considered far apart, such as logical and executable specifications and constructive and transformational approaches to program derivation. A great emphasis has been placed, in the design of Focus, on achieving small search spaces during program derivation. The program manipulation operations such as expansion, simplification and rewriting were designed with this objective. The role of operations that are expensive in search spaces, such as folding, has been reduced. Program derivations are documented in Focus in a way that the high level descriptions of derivations are expressed only using program level information. All the meta-level information, together with dependencies between derivations of program components, is automatically recorded by the system at a lower level of description for its own use in replay.","PeriodicalId":253963,"journal":{"name":"SDE 3","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124035424","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}

To address this need, the TEAM environment has been designed to support the integration of and experimentation with an ever growing number of software testing and analysis tools. To achieve this flexibility, we exploit three design principles: component technology so that common underlying functionality is recognized; generic realizations so that these common functions can be instantiated as diversely as possible; and language independence so that tools can work on multiple languages, even allowing some tools to be applicable to different phases of the software lifecycle. The result is an environment that contains building blocks for easily constructing and experimenting with new testing and analysis techniques.

The user sees and manipulates complex objects at various levels of detail. Many of the implications of changes are analyzed and made available to the user as frequently as the user wishes, without a mode change from editing to compiling or linking. To help provide these services in a uniform way that can readily respond to changes in the programming language(s) supported or in the preferences of individual users, some programming environments use attribute grammars.\u0000The attributed graph specifications (AGS's) defined here are inspired by attribute grammars but are free of their restriction to structures expressible by parse trees generated by context-free grammars. An AGS deals with whatever structure is appropriate in a given application. The graph concept here is not tied to any decision about pictorial representation. Indeed, we do not care whether the user sees pictures or text or a combination of the two. The AGS formalism is a uniform paradigm for specifying the desired relations among many and varied chunks of information, some of which are changed by the user. The benefits of the original attribute grammar formalism were confined to parse trees and severely restricted manipulations of parse trees. The AGS paradigm extends those benefits to software development on a larger scale.","PeriodicalId":253963,"journal":{"name":"SDE 3","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129933456","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}

Mostly, one has to face the choice between poorly or not at all integrated, independent tools, or highly integrated, most specialized, and often language dependent environments. The first choice offers very limited support for a complex task that needs a broad informational basis. The second choice often takes away the programmers' most cherished tools, forces him to adopt some different work discipline, and thereby eventually restricts his creativity. The toolset described in this paper integrates a dedicated version control system and shape, a significantly enhanced Make [Feld79a] program, on the basis of a common object model. This object model comprises multiple versions of software objects as well as conventional file system objects. Taking this approach made it possible to have a sufficiently integrated toolsystem for engineering software configurations while retaining the flexibility of the basic toolbox philosophy, permitting the use of 'off-the-shelf' tools, e.g. editors or compilers.","PeriodicalId":253963,"journal":{"name":"SDE 3","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117209001","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 Arcadia research project is investigating the construction of software environments that are tightly integrated, yet flexible and extensible enough to support experimentation with alternative software processes and tools. This has led us to view an environment as being composed of two distinct, cooperating parts. One is the variant part, consisting of process programs and the tools and objects used and defined by those programs. The other is the fixed part, or infrastructure, supporting creation, execution, and change to the constituents of the variant part. The major components of the infrastructure are a process programming language and interpreter, object management system, and user interface management system. Process programming facilitates precise definition and automated support of software development and maintenance activities. The object management system provides typing, relationships, persistence, distribution and concurrency control capabilities. The user interface management system mediates communication between human users and executing processes, providing pleasant and uniform access to all facilities of the environment. Research in each of these areas and the interaction among them is described.","PeriodicalId":253963,"journal":{"name":"SDE 3","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123686908","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}
