An architecture and object model for distributed object-oriented real-timedatabases

The confluence of computers, communications, and databases is quickly creat ing a distributed database where many applications require real-time access to both temporally accurate and multimedia data. This is particularly true in military and intelligence applications, but these required features are needed in many commercial applications as well. We are developing a distri buted database, called BeeHive, which could offer features along different types of requirements: real-time, fault-tolerance, security, and quality-of service for audio and video. Support of these features and potential trade -offs between them could provide a significant improvement in performance a nd functionality over current distributed database and object management sy stems. In this paper, we present a high level design for BeeHive architectu re and sketch the design of the BeeHive Object Model (BOM) which extends ob ject-oriented data models by incorporating time and other features into obj ects, resulting in a highly reflective architecture.
