Oracle PLSQL Online Training

PL/SQL is Oracle's procedural extension to industry-standard SQL. PL/SQL naturally, efficiently, and safely extends SQL. Its primary strength is in providing a server-side, stored procedural language that is easy-to-use, seamless with SQL, robust, portable, and secure.

What is so great about PL/SQL?

  • PL/SQL is a procedural extension of SQL, making it extremely simple to write procedural code that includes SQL as if it were a single language. In comparison, most other programming languages require mapping data types, preparing statements and processing result sets, all of which require knowledge of specific APIs.
  • The data types in PL/SQL are a super-set of those in the database, so you rarely need to perform data type conversions when using PL/SQL. Ask your average Java or .NET programmer how they find handling date values coming from a database. They can only wish for the simplicity of PL/SQL.
  • When coding business logic in middle tier applications, a single business transaction may be made up of multiple interactions between the application server and the database. This adds a significant overhead associated with network traffic. In comparison, building all the business logic as PL/SQL in the database means client code needs only a single database call per transaction, reducing the network overhead significantly.
  • Oracle is a multi-platform database, making PL/SQL and incredibly portable language. If your business logic is located in the database, you are protecting yourself from operating system lock-in.
  • Programming languages go in and out of fashion continually. Over the last 35+ years Oracle databases have remained part of the enterprise landscape. Suggesting that any language is a safer bet than PL/SQL is rather naive. Placing your business logic in the database makes changing your client layer much simpler if you like to follow fashion.
  • Centralizing application logic enables a higher degree of security and productivity. The use of Application Program Interfaces (APIs) can abstract complex data structures and security implementations from client application developers, leaving them free to do what they do best.
