PL/SQL is one of the parts of Oracle RDBMS, and it is important to know that most of the Oracle applications are developed using the client-server architecture. The Oracle database forms the server-side and requests to the database form a part of the client-side.
So based on the above fact and the fact that PL/SQL is not a standalone programming language, we must realize that the PL/SQL engine can reside in either the client environment or the server environment. This makes it easy to move PL/SQL modules and sub-programs between server-side and client-side applications.
Based on the architecture shown below, we can understand that PL/SQL engine plays an important role in the process and execute the PL/SQL statements and whenever it encounters the SQL statements, they are sent to the SQL Statement Processor
