这项研究是由协调问题特别倡议资助的 理论和协作技术。 这是十一位获奖者之一 在这种竞争下。 对协调合作活动的传统支持 软件工程师主要包括版本控制和邮件 不符合许多软件的要求 工程任务，如交互式组设计和调试。 在这个项目中，研究人员调查了 合作软件工程师的活动。 特别是， 他们开发了一种方法，允许：（1）一系列并发 控制机制，包括串行事务、并发 可串行化事务，并发不可串行化事务 允许其他事务访问各种类型的部分 结果，而不是控制;（2）警报器自动通知用户 （3）动态可变粒度 锁定，以及（4）与并发控制集成的实时声音 机制 在开发该方法时，研究人员使用 在共享窗口中完成的工作的结果，长事务， 分布式交互系统和其他系统。 研究人员 还研究如何通过以下方式自动选择特定方案： 该系统基于所要求的最低性能水平， user. 将开发几个原型应用程序， 展示了这项研究的新颖之处。

This research is funded under the Special Initiative on Coordination theory and Collaboration Technology. This is one of eleven winners under that competition. Traditional support for coordinating the activities of collaborative software engineers consists mainly of version control and mail systems and does not meet the requirements of many software engineering tasks such as interactive group design and debugging. In this project the researchers investigate flexible coordination of the activities of cooperating software engineers. In particular, they develop an approach allowing: (1) a range of concurrency control mechanisms including serial transaction, concurrent serializable transactions, concurrent non-serializable transactions allowing other transactions to access various types of partial results, and not control; (2) alerters automatically informing users of events in which they are interested; (3) dynamic variable-grained locking, and (4) live sound integrated with the concurrency control mechanism. In the development of the approach, the researchers use results from the work done in shared windows, long transactions, distributed interactive systems, and other systems. The researchers also study how a particular scheme can be automatically chosen by the system based on a minimum performance level requested by the user. Several prototype applications will be developed to demonstrate the novel aspects of this research.
