Advantages of Oracle PL/SQL:

• PL/SQL handles error handling efficiently and it allows an intelligent method of dealing with errors. It gives user-friendly error messages when the errors are detected.
• PL/SQL provides control to declare variables and accesses them in the scope of the block. These declared variables can be applied during query processing.
• Calculations in PL/SQL are carried out quickly and efficiently without applying Oracle engines. It enhances the transaction performance.
• There is portability of applications written in PL/SQL in any operating system. These applications are independent programs that initiate on any computer.

Career Path in Oracle PL/SQL

As soon as you choose to be a PL/SQL developer, you will be writing SQL based queries so that the performance of the database can be enhanced substantially. You will also be needed to evaluate the data outcomes and offering solutions, suggestions to the customers and also pertinent to document creation. In your career, you will be expected to consist of:

• A profound knowledge of Oracle database, its tools and utilities
• A sound understanding of programming constructs, packages, procedures, query writing and triggers
• A good knowledge of software development life cycle. You should be able to adhere to standard processes including code review, forming/executing unit level test cases.
• You should be in a position to frame and implement ETL solutions and processes.
• You should be able to form data models and design.
• With the passage of time you can also get transformed into a new set of technologies.
• You will also take the role of solution level and data level architect besides being DBA,
• Do you want to take a break from the programming languages and coding? You can think of shifting your domain into an analyst profile where the results generated are worked upon. Moreover, future business insights can be produced applying analytical tools.
• When you operate with PL/SQL which is an Oracle’s technology you let yourself to deal with every domain that Oracle has to offer.
• You can also work as a full stack developer and your roles and responsibilities can include controlling the backend and the front end of the application.
• Are you performing well in UNIX? You can migrate to security domain or take up the role of a tech operation analyst.
• You can also transition to several NoSQL databases’ developer role since the raise in big data technologies have demanded the application of NoSQL databases more than conventional RDBMS.
