This paper presents the development of an enterprise level Service Oriented Architecture design aimed at resolving the data access, integration and analysis issues of an existing multi-supplier and heterogeneous infrastructure commonly found throughout the UK Police Service. This paper describes new developments that deliver the data integration and new analytical needs of Performance Management and ensure access to timely, accurate and relevant data throughout the Force. A ‘proof of concept’ prototype has successfully been developed and implemented to demonstrate the feasibility of extending the life of legacy systems and using services to abstract data into a new Analytical Processor. The architectural model and resulting prototype have successfully demonstrated the feasibility of this development to deliver the data integration and analysis needs of Performance Management within a UK Police Force.
