9303403 Salzberg This is the first year funding of a three-year continuing award. Commercial relational database management systems provide many robust customer-tested utilities and services. Not only can traditional queries be answered efficiently, but also reorganization, recovery, concurrency, report writing, performance monitoring, distribution, importing and exporting utilities are available. It makes sense to add features to these mature products to support new applications rather than to write new software for new applications and then try to add these complex utilities. This project adds to relational database management systems support for versions of complex objects. It provides indexing on both time and version name. In addition, hierarchical objects composed of different record types (such as customer and order) can be dynamically clustered as they are entered in the database. This will enable customers dealing with hierarchical and/or versioned objects to take advantage of the robust capabilities of already existing large database management systems. ***

小行星9303403 这是一个为期三年的连续奖励的第一年资助。 商业关系数据库管理系统提供了许多经过客户测试的强大实用程序和服务。 不仅可以有效地回答传统的查询，而且重组，恢复，并发，报告编写，性能监控，分发，导入和导出实用程序。 为这些成熟的产品添加功能以支持新的应用程序，而不是为新的应用程序编写新的软件，然后尝试添加这些复杂的实用程序，这是有意义的。 这个项目增加了对复杂对象版本的关系数据库管理系统的支持。 它提供了时间和版本名称的索引。 此外，由不同记录类型（如客户和订单）组成的分层对象可以在输入数据库时动态聚类。 这将使处理分层和/或版本化对象的客户能够利用现有大型数据库管理系统的强大功能。 ***
