近年来，由于新广播或通信卫星的发射以及新服务的推出，基于卫星的数据广播已成为越来越多的关注焦点。此类广播系统的普及导致广播量和服务类型急剧增加。因此，需要一种系统，使普通用户能够从大量广播数据中有效地提取、存储和重用所需的信息。针对这一要求，作者提出了一种超级主动数据库系统（SADB）并描述了其设计和实现。所提出的 SADB 是活动数据库（事件触发数据库）对广播系统的改编。由于SADB必须快速处理发送给它的大量数据，因此接收动作和接收数据处理是独立于规则处理器设计的。本文评估了已实现系统的性能并显示了它可以处理的数据量。 © 2003 Wiley periodicals, Inc.

Satellite-based data broadcasting has been the focus of increasing attention in recent years due to launches of new broadcasting or communications satellites and the initiation of new services. The popularization of these kinds of broadcasting systems has led to a dramatic increase in both the broadcast volume and types of services. As a result, a system is needed that will enable an ordinary user to efficiently extract, store, and reuse required information from the massive amount of data that is broadcast. In response to this request, the authors propose a super active database system (SADB) and describe its design and implementation. The proposed SADB is an adaptation of an active database, which is an event-triggered database, to a broadcasting system. Since the SADB must quickly process the massive amount of data that is sent to it, the reception actions and reception data processing were designed independently of the rule processor. This paper evaluates the performance of an implemented system and shows the data volume that it can handle. © 2003 Wiley Periodicals, Inc.
