Development of a high performance, memory based, relational database system using Ada

An attempt is made to describe the development, in Ada, of a memory-based relational database system to support a high-performance, real-time wagering system which must run at a minimum of 200 transactions per second. The authors report the background to the task at hand; why Ada was chosen; the initial problems of starting the project; why a memory-based, relational database system was needed; and how it was developed. The usage of Ada to this point in the project and some of the problems encountered are summarized
