1.1 BACKGROUND OF STUDY 

Computerization is defined as the control of processes by computers and its peripherals. Today it would be difficult to think of any process, business or action that could not have profited from the numerous benefits of the computer system. Controlling process or devices with computer started long ago since the invention of computer. In the 20th century inventors tried to make processes easier with the use of computers. Secondly computerization has been greatly applied or used in controlling process that requires frequent action such as drug procurement, drug management, drug tracking and drug distributions in hospital management information system in pharmacy departments of hospitals. This project which is drug procurement and distribution tracking system provides a computer based information management system in a Pharmacy Department of the University of Nigerian Teaching Hospital (UNTH) Enugu by designing a cost effective, user friendly application, incorporating key attributes of data integrity and system security suitable for use in the pharmacy department of the hospital using Microsoft Access software in developing the database and visual basic as the   programming language. The overall aim of this project is to optimize time and material in the processing of data needed for effective operation of large pharmacy department of a hospital. By this approach, data integrity, data redundancy, and consistency will be ensured. Drugs are the chemical substances that are administered to patients for curative purposes and prophylaxis. It can also be known as a medicine, because it is the essential part of peoples care. The ability of the computer to store and retrieve information at a very fast and efficient rate makes its application useful in management operations. Drug management involves drug procurement, drug distribution, drug tracking and its information management. Drug distribution is concerned with distribution of drugs within the different medical units or departments in a hospital, while drug procurement is concerned with the purchasing activities of the drugs by the pharmacy department of the hospital. In the same vein, drug tracking is concern with the continuous monitoring of the actual quantity of drugs held in the hospital pharmacy or any other drug warehouse /store. It also controls the stock level. Pharmaceutical unit in a hospital is concerned with drug management activities. They carry out the responsibility of making appropriate selection and drugs used by formulating an annual, monthly, weekly or daily list of drugs requirement and  management reports. However, in some hospitals today, some pharmacists still use the manual system of operation which can lead to inappropriate drug management errors due to problems of handling voluminous file within a short period of time. This could make data to be easily inaccessible and also delivery of drugs can lead to misplacement of patients’ files.
