SIMS, a Social Science Information Management System, has been developed by the Social Science Data and Computation Center (DACC) at the University of Wisconsin for the purpose of providing the social scientist with a personalized data base management system (DBMS). Over the past four years many DBMS were surveyed and their basic features compared to our requirements. All systems surveyed had their strong and weak points but no one system was found to satisfy all our needs. In addition, new and improved methods and algorithms for language processing, storage and retrieval, and analysis capabilities have been developed by DACC and others since the advent of these earlier systems. These facts, coupled with the fact that conversion of existing systems seemed impractical due to their machine dependence, has resulted in the development of SIMS. It is the intent of SIMS through its features and basic design to serve as an information processing tool for social scientists and others working with large and complex data files.
