Enabling the Commerical Realization of Temporal Databases

Snodgrass广泛的数据库应用程序管理时变信息。这类应用程序通常使用传统的关系系统，除了日期和时间数据类型之外，这些系统几乎不支持时态应用程序。研究界在将二十年来研究的许多新思想纳入共识时态查询语言TSQL2方面做了出色的工作。SQL3委员会通过批准一个新的部分SQL/Temporal，开始了将TSQL2的功能转移到标准中的过程。作为GOALI项目的一部分，正在设计TSQL2验证套件。其次，整个语言的功能原型正在开发中；这个原型可以用验证套件进行测试。一组比较SQL和TSQL2解决方案的案例研究利用原型对语言结构的实际效用进行了评估。这些工件将提供给标准组织和有兴趣通过他们的产品实现时态数据库技术的开发和生产收益的供应商，从而确保将见解从时态数据库研究社区直接转移到行业。＊＊＊

*** 9632569 Snodgrass A wide range of database applications manage time-varying information. Such applications typically use conventional relational systems, which include little support for temporal applications, other than date and time data types. The research community has done a remarkable job of incorporating the many novel ideas of twenty years of research in the consensus temporal query language TSQL2. The SQL3 committee has started the process of transferring the facilities of TSQL2 into the standard by approving a new part, SQL/Temporal. As a part of this GOALI project, TSQL2 validation suite is being designed. Secondly, a functional prototype for the entire language is being developed; this prototype can be tested with the validation suite. A set of case studies comparing SQL and TSQL2 solutions utilizes the prototype to provide an evaluation of the practical utility of the language constructs. These artifacts will be made available to the standards bodies and to vendors interested in enabling via their products the development and productions gains made possible with temporal database technology, thereby ensuring a direct transfer of insights from the temporal database research community to industry. ***
