Chapter 2 - Database System Concepts and Architecture Data Models, Schemas and Instances A characteristic of the database approach is that it provides a level of data abstraction, by hiding details of data storage that are not needed by most users. A data model is a collection of concepts that can be used to describe the structure of a database. The model provides the necessary means to achieve the abstraction. The structure of a database is characterized by data types, relationships

CHAPTER 1 INTRODUCTION Overview of the current system Computer world is now at our hands, this give improvement and development of all programs in the different agencies, in offices and in schools. Paper work become easy, computation is faster, record keeping and bringing out is fast. In schools, all works became easily fast to look at record, easily to reproduce student record. Since, computation of grades is one burden of the teachers, computerization made the answer in solving, in recording

maintains a fully stocked parts inventory. Each center also maintains a manual file system in which each car’s maintenance history is kept: repairs made, parts used, costs, service dates, owner, and so on. Files are also kept to track inventory, purchasing, billing, employees’ hours, and payroll. You have been contacted by the manager of one of the centers to design and implement a computerized database system. Given the preceding information, do the following: a.

A special-purpose extension of the EntityRelationship model for the needs of conceptual modeling of geographic applications, called the Geo-ER Model, is presented. Handling properties associated to objects not because of the objects’ nature but because of the objects’ position, calls for dealing -at the semantic modeling levelwith
