1.1 Introduction
Distributed Databases Systems are a set of logically networked computer databases, managed by different sites and appearing to the user as a single database. A database is an organized collection of data. It is the collection of schemas, tables, queries, reports, views, and other objects. The data are typically organized to model aspects of reality in a way that supports processes requiring information, such as modeling the availability of rooms in hotels in a way that supports finding a hotel with vacancies. A database management system (DBMS) is a computer software application that interacts with the user, other applications, and the database itself to capture and analyze data. A general-purpose DBMS is designed to allow the definition, creation, querying, update, and administration of databases. Designing a Distributed Database, it is necessary that it be entirely resident on various sites in a computer network or its portion. In this logic, there must be at least two sites hosting the database, and not necessarily each one, in the Computer Network (Tomar, 2014).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Limitations of the Study and Definition of technical terms.
