Statement vs prepared statements(whats the use of pstmts over stmts), why microservice when the same can happen in monolithic(Not normal differences expected something else), how Rest API will work (internal process)

Question

Accepted Answer

Prepared statements are precompiled SQL statements that can improve performance and security. Microservices offer scalability and flexibility over monolithic architecture. REST API works by using HTTP methods to interact with resources.

Prepared statements are precompiled SQL statements that can be reused multiple times, improving performance by reducing database load and preventing SQL injection attacks.
Microservices allow for independent deployment, scalability, and flexibility compared to monolithic architecture, which can be more difficult to scale and maintain.
REST API works by using HTTP methods like GET, POST, PUT, DELETE to interact with resources over the web, providing a stateless communication protocol for client-server interactions.
