DBMS is a high-level query language because it is used for real work data stored in relational data model, it evaluate queries very efficiently. In this way, users can manage large amount of structured data by DBMS. Users don’t have to write low level language to realize some specific functions, don’t need to debug or testing the application functions, therefore DBMS reduces development time.In DBMS, the data model, which is called schema, for example relational, we can have entities and attributes

DATABASE DESIGN One of the most important if not the most important aspect of a database is the database design process. It is a must that the design is good and functional. A database consists of many different parts of an engineer’s design, which together makes up a complete database system. A database system is designed to manage large bodies of information. Database design is the construction of a database as a subsystem of an information system. Therefore, the database design process is

will be required to design and develop a database application using a modern fourth generation language system. This course teaches students data modeling and design techniques and how to transform data models into database designs. Another basic component of this course is the use of SQL – Structured Query Language. Students will also learn how to create databases, modify databases, and develop queries using SQL. In addition, this course also teaches the management of database resources in an
