This is collaborative research with Prasun Dewan, Purdue University (IRI-9208319). Much of software engineering-design, programming, debugging, testing, code reviews, program demonstrations, and program management-requires collaboration among multiple users, possibly geographically dispersed. In this project the researchers propose to investigate flexible support for the activities of cooperating software engineers. In particular they propose to investigate an approach that offers (i) a wide range of concurrency control mechanisms including serializable transactions and interactive transactions; (ii) fine-grain access control for collaborative applications that allows a user to recover from other users' mistakes and explore various alternatives with them, (iv) a multidimensional inheritance model that allows collaboration parameters to be specified independently in hierarchies of groups of objects and groups of users; and (v) multimedia support integrated with concurrency control, access control, and undo/redo. The unique features of this research are its focus on the relationships of these five goals, on flexible mechanisms for achieving each of the goals, and on structured specification of options by end-users. The researchers will use results from previous research done in flexible coupling, long transactions, adaptive concurrency control systems. inheritance, single-user undo/redo, capability-based protection, collaborative tools, and software engineering tools, They plan to implement the approach by extending an existing system developed at Purdue and Minnesota. They will evaluate the performance of the various collaboration methods and study how a particular method can be automatically chosen by the systems based on a minimum performance level requested by the user. In addition to an understanding of the applicability of collaborative technology to software engineering, the research will produce prototype software engineering tools to demonstrate the novel aspects of the research.

这是与普渡大学 Prasun Dewan (IRI-9208319) 的合作研究。 许多软件工程——设计、编程、调试、测试、代码审查、程序演示和程序管理——需要多个用户之间的协作，这些用户可能在地理上分散。 在这个项目中，研究人员建议研究对合作软件工程师活动的灵活支持。 他们特别建议研究一种方法，该方法提供（i）广泛的并发控制机制，包括可序列化事务和交互式事务； (ii) 协作应用程序的细粒度访问控制，允许用户从其他用户的错误中恢复并与他们一起探索各种替代方案，(iv) 多维继承模型，允许在对象组和用户组的层次结构中独立指定协作参数； (v) 与并发控制、访问控制和撤消/重做集成的多媒体支持。 这项研究的独特之处在于它关注这五个目标的关系、实现每个目标的灵活机制以及最终用户选项的结构化规范。 研究人员将使用之前在灵活耦合、长事务、自适应并发控制系统方面的研究成果。他们计划通过扩展普渡大学和明尼苏达大学开发的现有系统来实施该方法。 他们将评估各种协作方法的性能，并研究系统如何根据用户请求的最低性能水平自动选择特定方法。 除了了解协作技术在软件工程中的适用性之外，该研究还将制作原型软件工程工具来展示该研究的新颖之处。
