描述了 ORION-1 和 ORION-1SX 的各种架构组件，并对当前实现进行了回顾。消息处理程序接收发送到 ORION 系统的所有消息。对象子系统提供高级数据管理功能，包括查询优化、模式管理、长数据管理（包括文本搜索）以及对版本化对象、复合对象和多媒体对象的支持。事务管理子系统协调并发对象访问并提供恢复功能。存储子系统管理对象的持久存储并控制辅助存储设备和主存储器缓冲区之间的对象流。在 ORION-1 中，所有子系统都驻留在一台计算机上。 ORION-1SX架构在共享数据结构的管理以及这些子系统及其组件的分布方面与ORION-1显着不同。 >
Various architectural components of ORION-1 and ORION-1SX are described and a review of the current implementation is provided. The message handler receives all messages sent to the ORION system. The object subsystem provides high-level data management functions, including query optimization, schema management, long data management (including text search) and support for versionable objects, composite objects, and multimedia objects. The transaction management subsystem coordinates concurrent object accesses and provides recovery capabilities. The storage subsystem manages persistent storage of objects and controls the flow of objects between the secondary storage device and main memory buffers. In ORION-1, all subsystems reside in one computer. The ORION-1SX architecture is significantly different from ORION-1 in the management of shared data structures and distribution of these subsystems and their components. >
