ABSTRACT

Given the present state of data upkeep and vital nature of record data management, one of the most promising data management systems is the introduction of automated database system into data and record up keeping as improving the security and enhancing easy accessibility data and records. This term paper was carried out to identify the importance of automated database management system on student’s data and record up keeping. The use of automated database system is a wide spread notion today, the academic staff finds it very efficient and durable in the proper up keeping of data because it prevent redundancy in data usage, takes care of unauthorized access to students record, protect data and information from vulnerability to damages, and improves easy accessibility, retrieval and proper management of data and record keeping. so the general awareness and the usage of the automated database management system, especially with the use of the relational model will enhance the proper up keep and management of data and record keeping of student information and what have you.

INTRODUCTION

A Database is a structured collection of data that is managed to meet the needs of a community of users. The structure is achieved by organizing the data according to a database model. The model in most common use today is the relational model. Other models such as the hierarchical model and the network model use a more explicit representation of relationships (see below for explanation of the various database models). A computer database relies upon software to organize the storage of data. This software is known as a database management system (DBMS). Databases management systems are categorized according to the database model that they support. The model tends to determine the query languages that are available to access the database. A great deal of the internal engineering of a DBMS, however, is independent of the data model, and is concerned with managing factors such as performance, concurrency, integrity, and recovery from hardware failures.
