We will describe how a high-performance database system was successfully deployed for the first application, fulfilling its performance requirements, and even beating out a specially crafted component. For the second application, we will present its rather challenging requirements, and will hope that these will stimulate discussion at the workshop. These applications are required to respond in real-time to query and update requests while simultaneously satisfying strict availability requirements. Traditional database systems are not well suited to applications of this type. In this talk we describe some of the real-time database issues required to support call processing applications.
Temporal databases deal with the storage and manipulation of data about time.
These two areas are combined within a real-time database system. Many of these applications deal with data so voluminous in a market so competitive that issues of efficiency of resource utilization are of paramount importance. Both semiconductor and display manufacturing are serving as research vehicles, and the EML has been equipped for the development and testing of control solutions in both arenas. The current challenge is to define and develop generic methods for the integration of these results into a multi-level control solution. A critical issue that must be addressed in this context is database design and management.
