There is a growing need for the information to become computerized so that it can be suitably stored. This is where databases come into the picture. Databases are convenient storage systems which can store large amounts of data and together with application programs such as interfaces they can aid in faster retrieval of data. An initiative was taken to design a complete database system for a hospital management such as Bangladesh Institute of Research and rehabilitation in Diabetes, Endocrine and Metabolic disorders (BIRDEM) in Dhaka so that its information can be stored, maintained, updated and retrieved conveniently and efficiently. The existing information in BIRDEM is partly computerized via databases only in patients’ admissions, doctors’ appointments and medical tests and reports sections. A partly slow and tedious manual system still exists in BIRDEM for example, in record of ambulances in service, assigning ward boys and nurses to rooms, the billing process and record of doctors’ prescriptions etc. However, this paper outlines one complete database design for the entire BIRDEM hospital in which data maintenance and retrieval are in perfect harmony and speedy. Sample SQL-based queries executed on the designed system are also demonstrated. Keywords- Database system, entity relationship relational model, normalization, SQL-based queries.
