Code placement in application server

Code placement in application server in PL/SQL

In an application server architecture, code placement is an important consideration for PL/SQL developers. Here are some best practices for code placement in an application server:

1. Place application logic in the middle tier: The middle tier of an application server architecture is responsible for executing business logic and interacting with the database. This is the ideal place to put your PL/SQL code, as it allows you to separate your application logic from the database and makes it easier to manage and maintain.
2. Use a modular approach: Use a modular approach to code placement, with each module containing related functionality. This makes it easier to manage and maintain your code, and allows you to reuse code across different applications.
3. Use a layered architecture: Use a layered architecture to organize your application code into distinct layers, such as presentation, business logic, and data access. This allows you to separate your application concerns and make it easier to manage and maintain your code.
4. Use a caching strategy: Use a caching strategy to improve performance by reducing the number of database calls required. This can be especially useful for frequently accessed data or data that changes infrequently.
5. Use connection pooling: Use connection pooling to manage database connections efficiently. Connection pooling allows you to reuse database connections, which can improve performance and reduce overhead.
6. Follow security best practices: Follow security best practices to protect your code and data from unauthorized access. This includes encrypting sensitive data, using secure communication protocols, and implementing proper authentication and authorization controls.
