Data Manager for Evolvable Real-Time Command and Control Systems

Abstract

We describe the design and implementation of real-time data management services. These services combine technologies developed in the context of real-time distributed object management, object DBMSs, and scheduling. This combination simplifies many of the services, and produces a result which is greater than the sum of its parts, because it can be used to improve the portability and flexibility of real-time applications. 1 Introduction Many real-time command and control systems have been deployed which use custom-written real-time data management (RTDM) software that is highly tuned to particular requirements. This custom software is not only expensive to develop, but because it is entwined with the applications, must be rewritten when requirements change. We have developed an approach that makes real-time command and control software more evolvable by using shared, flexible RTDM services. This paper surveys past and ongoing RTDM and distributed object systems work by the authors and..
