Creating Databases with the Oracle Database Configuration Assistant This chapter describes using the Oracle Database Configuration Assistant (DBCA) to create and delete Real Application Clusters databases. It explains how to decide whether to manually create your database and how to use the DBCA to delete Real Application Clusters databases. This chapter also briefly discusses migration and multiple Oracle homes issues. The topics in this chapter include: Using the Database Configuration Assistant Benefits of Using the Oracle Database Configuration Assistant Creating the Database after Installation Using the Database Configuration Assistant Creating a Real Application Clusters Database with the DBCA Deleting a Database with the Database Configuration Assistant Using the Database Configuration Assistant The DBCA creates your database using the optimal flexible architecture (OFA) . This means the DBCA creates your database file

Procedural language fallows TopDown approach , that means flow starts from main and goes through functions ./ function calls. Object Oriented Programming fallows Bottom Up approach, That means.. everything is wrapped in object / classes, so these classes are building blocks of your application . So Classes with data, members joined will constructs your application with Object communication / messaging. and also OOPS has many benifits like Data Abstraction, Inheritance, Polymorphism (compile & runtime) etc.
