Development of a CASE Repository Integrating Software Processes and Products

这个项目的研究人员开发了一个存储库，可以集成软件过程和产品的CASE环境。第一年是利用PCTE进行数据集成的基础设计，对本课题组开发的原型KyotoDB进行了重组，使其能够利用PCTE模式定义集提供的对象管理服务和对象流数据交换格式。第二年，也就是最后一年，对KyotoDB进行了重组，使其能够利用PCTE模式定义集提供的对象管理服务和对象流数据交换格式。我们设计了先进的数据集成服务，不仅可以管理对象和链接的类型，而且可以管理对象、链接和属性之间的语义约束。这些约束管理服务，无论是结构上的还是操作上的约束，都不应该分散在应用程序的每个部分，而应该作为每个应用程序的公共服务在存储库中共享。为了为每个特定的应用程序量身定制这些服务，我们开发了一个工具，根据给定的类型和约束的定义来生成数据访问功能的框架。在过程集成部分，我们从用户界面的角度出发，为过程生成提供了一个真实的竞技场。我们开发了一个语义导向的图形编辑器称为UGE，并得到了初步的结果的UI模型的基础上明确的分类信息，即表示信息，透视信息，概念信息。

The investigators of this project developed a repository that can integrate software processes and products in CASE environments. The first year of the project was spent for basic design of data integration using PCTE.We restructured KyotoDB,of which prototype had been developed by our group, so that it can make use of object management services provided by PCTE schema definition sets, and of a data exchange format called the object stream.In the second and last year of the project, we designed advanced data integration services that can manage not only types of objects and links, but also semantic constraints among objects, links, and attributes. These constraints management services, both for structural and operational constraints, should not be scattered in every part of application programs, but be shared in a repository as common services to every application. In order to tailor those services for each specific application, we developed a tool to generate frameworks of data access functions based on given definitions of types and constraints. The repository designed here can be used to navigate software products and also to facilitate impact analysis in software maintemance.In the part of process integration, we approached from user interface that provides a real arena for process enaction. We developed a semantic-directed graphical editor called UGE,and got initial results of a UI model based on a clear classification of information, that is, presentation information, perspective information, and conceptual information.
