ORACLE SQL/PL SQL
About ORACLE SQL/PL SQL
PL/SQL is Oracle's procedural language addition to SQL. PL/SQL authorizes you to mix SQL statements with procedural constructs. PL/SQL Designers, an Integrated Development Environment for maturing software in the Oracle database environment, focuses on the development of PL/SQL stored-program units.
Who Uses
Application programs and Oracle device often allow customers access to the database without using SQL directly, but these applications in turn must use SQL when executing the user's request. PL/SQL fully supports SQL data types. You not required convert between PL/SQL and SQL data types.
For Example
PL/SQL only can achieve in an Oracle Database. It was not create to use as a standalone language like Java, C#, and C++. In other words, you cannot develop a PL/SQL program that runs on a method that does not have an Oracle Database.
SCOPE
PL/SQL is not increase, but not going away either. Because it is used in the Oracle database, and the Oracle database is a unit of enterprise systems world-wide, it will outlive you. PL/SQL and ORACLE SQL can do integration, call web services, write files, and you can build user interfaces with PL/SQL and tools like Application Express (APEX). Hereafter scope of being an SQL Developer it is not just finite to Computer Science, but you can see it revolving around Retail, Finance, Healthcare, Science & Technology, Public Sector, in short everywhere. All organizations need a database for the space of their data
Eligibility
It will require a few months of execution with SQL code and to memorize the theory for the exam. I personally started with small to no knowledge of SQL and precede it after dedicating myself for 3 months. The major objective where SQL was designed was to give the possibility to common people get interested data from database. It is also English like language so anyone who can use English at a basic pitch can write SQL query easily.
For Example
If you have a basic skill of Database, source code, text editor, basis software programming concepts. You will be able to absorb and understand all the concepts much quicker and easier
