The properties and design of database systems be incorporated in the curriculum of information technology (1).Central to the concept of a database is a collection of records, information, and answers to some grumpy queries. In a relieve oneselfn data base, there is a dovetailed description of the facts held in order in the database. This is referred to as schema. In a typical schema, there would be several linked objects and their related data. You can actually juxtapose the said objects similarity versus their contrasts in a schematic table from a database. there argon several ways of setting up a schema to organize a database these argon referred to as data rides or data base models (5). The just about popular and user friendly is the relational model which retrieves the data in rows and columns, arranged into tables . It highlights the links between the tables of the common objects in them. Other models, which are more technical, are the hierarchical model and the network model.
