What Is Oracle SQL Developer?

Oracle SQL is a programming language that allows database users and administrators to perform database tasks and undertake projects in fewer clicks and keystrokes. It is a graphical user interface that was designed with the objective of helping the user save time used during operations and maximise the return on investment (ROI) in the Oracle Database technology stack. It runs on any operating system that supports Java and supports Oracle Database 10g, 11g and 12g.

Oracle PL/ SQL today has a number of real-life applications:

1. For the developer
   While working, SQL Developer gives developers access to SQL, PL/ SQL, stored Java procedures and XML. It lets them run queries, generate execution plans, and export data in a number of formats like XML, HTML, PDF etc. It also lets them execute, debug, test and document database programs.
2. For the DBA
   Since the launch of version 3.0, SQL Developer is not just limited to developers in its applications. The DBA panel provides database administrators with a set of interfaces for their most critical tasks. Among other things, it provides support for Oracle Auditing, user and role management, Recovery Manager (RMAN) and data pump.
3. For the web application developer and administrator
   Oracle SQL Developer lets you administer Oracle Rest Data Services to create and alter restful services. It integrates with Oracle APEX to allow you to browse applications and perform several Application Express activities. You can browse, export, import, drop or deploy applications using Oracle SQL Developer.

What is PL/ SQL?

PL/ SQL is a block-structured language that lets developers combine the power of SQL with procedural statements. It is a database-oriented programming language that extends the applications of SQL with procedural capabilities. PL/ SQL allows better performance and error handling and uses block structures that can be nested within each other.

An Oracle PL/ SQL Developer Certified Associate demonstrates expertise in building database-centric Internet applications for Oracle Database 11g and Oracle Database 10g. It also gets you one step closer to becoming an Oracle Forms Developer Certified Professional.

Why Use PL/ SQL?

An application using Oracle Databases cannot work unless correct and complete data is used. The most efficient way to do this is by exposing the database only through an interface that hides the implementation details. This is called a smart database or smartDB paradigm because the data can be viewed and modified only through a PL/ SQL interface.
