    • A computer-implemented system for facilitating cross-subsystem queries of a plurality of building automation subsystems includes a first database storing a logical model for a building automation system. The system further includes a second database storing information for the plurality of building automation subsystems. The second database relates information for the plurality of building automation subsystems based on the logical model of the first database. The system also includes a query engine configured to decompose a cross-subsystem query received from an application into a plurality of subsystem queries using the information of the second database.
    • 用于促进多个楼宇自动化子系统的跨子系统查询的计算机实现的系统包括存储楼宇自动化系统的逻辑模型的第一数据库。 该系统还包括存储用于多个楼宇自动化子系统的信息的第二数据库。 第二数据库基于第一数据库的逻辑模型来关联多个楼宇自动化子系统的信息。 该系统还包括被配置为使用第二数据库的信息将从应用程序接收的跨子系统查询分解为多个子系统查询的查询引擎。
