Abstract:LogicaCMG developed SABRE, a spatial business rules server. Its purpose is to process queries for predefined business rules based on a given location. SABRE was rapidly developed as a project for 'masterclass' employees. Although a functional demo was created, SABRE remained a simple prototype not ready for commercial purposes. LogicaCMG's goal is to redesign SABRE for commercial purposes, such as for instance tracking and tracing. This project focusses on the optimization of the database part, which will be the foundation of SABRE. If SABRE will be commercially deployed we can expect massive usage, and very high performance requirements. Therefore it's essential to develop SABRE from the ground up in such a way that maximum performance is achieved. The SABRE architecture consists basically of a Service Provider (SP), Web service (WS) and a Database (DB). The SP requests certain information from the DB through the WS. The aim of this project is to develop a working version of the redesigned SABRE application fit for demonstration purposes. The focus will be on the DB part, therefore the WS will support only one service (e.g. AREA-event). The objective of this assignment is to study the performance and scalability of the DB. The two most important scalability aspects are: how does the DB cope when the amount of requests increases and how does the DB cope when the amount of data increases.
