An Oracle database is a collection of data treated as a unit. The purpose of a database is to store and retrieve related information. A database server is the key to solving the problems of information management. In general, a server reliably manages a large amount of data in a multiuser environment so that many users can concurrently access the same data.

Course Objectives

Upon successful completion of the course, the learner will be able to

  • This course helps you to develop any application which contains the Database.

  • Oracle is one of the widely used Databases for all web developers who like to build an application using JAVA, PHP, PEARL or Python etc.

  • With the help of ER modelling you will be creating and maintaining the Database tables by exploring simple queries to complex functions using Oracle.
