DESIGN AND IMPLEMENTATION OF DATABASE SYSTEM FOR PATIENT MANAGEMENT SYSTEM
The study was carried out to verify all the manual processes involved in patient management system and to seek for a way of automating the system for effective operations.
Since, there is continuous moves towards technological advances that enhanced productivity of labour and free human beings of task done more economically by machines. Computer n ts applications have become indispensable vital tools in economic, industrial and social development of the advanced countries of the world. Nigeria as a developing country cannot afford to lay too far behind in this kind of revolution. Therefore there is every need to know in energy discipline the areas which attracts computerization and why they need it.
In this project, the software engineering principles were applied in the analysis, design, coding testing of software serious attention was also give to the design of the user interface.
In the development of the software, visual basic programming language was used due to its support for all the features desired. A brief user’s guide is also provided. The end result is a software that is very effective and efficient in meeting its objectives and at the same time user friendly.

1.1 THEORETICAL BACKGROUND
Database is a collection of logically related files, organized in a manner to satisfy the needs of an organization. A database is a store of data structured so that access and update can be made by different people in different ways without needs to change its design or content for this to happen, it is essential that all data items are logically related.
Database is always necessary to store date items once, because of it, input cost are lower. Duplicate letters are largely dominated thereby saving space and ensuring data consistency. Data is defined as an unprocessed facts. They are raw fact that are unprocessed. Data does not have meaning. Information are processed data through the computer, which process different type of information. Information in the computer is stored in codes. File is the collection of related filed, field is the collection of data items.
Database management system are important, because important information requirement and non-specialist need easy ways of accessing this information. Large amount of data with many types of records occurring many times in database management system. Also in database management system, complex data structures including many relationships between data items. Many organization will have many use requirement in data base management system. Organizations will also have many frequent demand for changes to be made which only unflexible database management system can cope with.
Data is viewed as a source to be shared by as many process as possible. As a result, data must be organized in a way that is flexible and adaptable to un anticipation requirements. The data which they stored in anticipation of requests, and the requests themselves. Data may be stored as references to documents, microforms or computer coded text, graphics etc. the service may be offered on a local basis or through a telecommunication network. Database system may be operated by organizations for their own benefit or offered to the public on a subscription basic. The output from database services is either a document or computer data presented, say, on a video display unit or a voice output.
The main purpose of database is to satisfy the user information needs. The way in which these needs are expressed largely determined the principles of operation of a particular database system.
Rerhaps the most straight forward request for database is when the user supplies a complete reference for a document. The job of the service then is to locate a copy of the document and deliver it to the user. This is usually referred to as document retrieved service. It may be aided by computers in compelling the index to the documents in store, and in physically locating a required document as in a computerized warehouse.
More after then not, however, database need are expressed in terms of a request for data such as, how many patient are being admitted monthly in a hospital? Or what kind of sickness of a patient? To answer such questions reference must be made to records stored either in printed form or as computer coded data. The first of there is often refered to as information retrieval, the later as database search, when the index to the printed record is computerized.
The database distribution system, with the added facility of storage at computer coded text, offer one approach to reducing, the physical size of records, and to mechanizing their search and retrieval the records unfortunately, first have to be converted into computer compatible form, and can be consulted only after reconversion via some printing or display device.
1.2 STATEMENT OF THE PROBLEM
There has been this problem of too much work for the nurses in the hospital. Owing to the growing population of patient in the hospital, the nurses is faced with hips of file. At times, sorting out a particular patient file takes most a month.
Also there has been cases of missing files. Due to lack of security in the office and the poor filling system in use, the patient files at times get lost and it then becomes difficult to access the concerned patient information.
This bitter complaints and the delay in the receiving of information for the management had been the major concern and therefore has intensified the need to design a software which will go a long way in tackling these problems and at the same time helps to quicken database processing.
1.3 PURPOSE OF THE STUDY
The purpose of the study is to design and implementation of database system for patient management system.
1.4 AIMS AND OBJECTIVES OF THE STUDY
Due to the controversy surrounding the manual processing involved in patient management system, it was felt that a study of this nature will clarify the causes of the problems being faced by the concerned nurses and map out the necessary solutions and techniques to the problem.
Also the manual processing in patient management system was found to be cumber some, tedrous and ineffective which lead to inaccurate and unreliable results. It is the aim of this work therefore to nemedy this ugly situation by making the task involved to be easy and effective thereby making provision for accuracy and reliabilibity of the results.
More so, this work has the objective of correcting all the mistakes being made while operating a manual made while operating a manual system of data storage and retrieval including the delay encountered in retrieving the information to work with.
1.5 SIGNIFICANCE OF THE STUDY
i. It will help to give nurses the elementary knowledge as how computer can be used to store and retrieve.
ii. The software developed will help to create and store database about the patient. The database can be retrieved at any time by the users.
iii. Adequate security is offered to the database stored to avoid corruption by wrong users. This is done through the use of password to project the database.
iv. It is easy to obtain database or locate a particular patient in that hospital by retrieving database concerning him from the system.
