Computer data base for cleft lip and palate research

This is a description of a comprehensive system for collection and storage of information about treatment and follow-up of cleft lip and palate (CLP) patients. The emphasis is on clinical research, including as much data as possible, and storing it according to the rules of the relational data base model to maintain flexibility. The information is derived from hospital records, clinical examinations, speech evaluations, and measurements of dental casts and cephalograms. In this complex setting, it is important to respect the rules of proper computer data base organization and implementation to insure the long-term correctness and integrity of stored data.
