Oracle Procedure Purpose Explained

In Oracle, a procedure is a type of stored procedure that executes a series of SQL statements and logical operations. Its purpose includes:

1. Encapsulate business logic: bundling a series of SQL statements and logical operations in a procedure for easier management and maintenance.
2. Improve performance: Since stored procedures are executed on the server side, it can reduce network transmission and enhance execution efficiency.
3. Reuse: the same stored procedure can be called in multiple places, allowing for code to be reused.
4. Security: Stored procedures can be granted to specific users or roles, enhancing the security of the data.
5. Transaction control: Stored procedures can include transaction handling logic to ensure that multiple SQL statements are executed in the same transaction.

In a nutshell, the role of procedures in Oracle is to provide a convenient, efficient, and reusable way to manage and execute business logic.
