Oracle database is a centralized repository of related data. This helps to store, manage and define data in the database. Considering a firm like Bank which has many customers with more sensitive information. To store and manage all customer related information in a system, we require a Database. Oracle is the one of the leading database server provider who allows users to interact with data within its database. Currently in market we have Oracle 11g and 12c version of database.
SQL is a structured query language which is used to interact with many database like Oracle (Oracle Corp),DB2 (IBM) and SQL Server(Microsoft), but PL SQL is Proprietary Oracle language which can be used to interact with Oracle Database only.
Using SQL you can instruct the database to perform a task using one command at a time. Oracle PL SQL procedural language extension to SQL is a program language that is group of instructions can be performed on a database many times or concurrently from which one instruction can depend on other instruction. The advantage of PL SQL is easy to learn, easy to manage code as it is followed by OOPs concept(C,C++ languages)
What we do at TIC Academy for Oracle PL SQL?
As said, Oracle PL SQL is a preferable language to learn fast and easy to understand. Most of the fresher’s or those who does not have exposure of any technology before, we train them in an effective way and make them very comfortable and confident with Oracle technology. We not only teach Oracle PL SQL, we also help them to understand how IT SDLC process is and help them to prepare of Oracle interview by providing adequate interview tips.
Job Opportunity for Oracle PL SQL?
There are plenty of job opportunities available in the market. Database field will never go down as Database is a heart to many application system. No system can run without database.Every system will require a database to store information, hence learning PL SQL will surely provide a way to work in leading IT companies.
