What you must know as a database developer?

  • You need to know how to implement the specified functions for accessing and manipulating the application data.
  • You need to know how to implement the rules for data integrity.
  • You need to know how to implement the data model that the application requires.

You must remember that you can access an Oracle Database only through a client program, and that the SQL language is that client program’s interface to the Oracle Database.

You will learn how to access the Oracle Database by using two clients that are packaged with the Oracle Database and designed for developers: SQL Developer and SQL*Plus. Both allow you to issue the SQL statements you need in order to create and test your application’s database component without doing any client programming.
