Transaction Script
Transaction Script is a design pattern in software architecture that organizes business logic by creating a separate script or procedure for each business transaction or use case. It involves writing straightforward procedural code to handle specific operations, such as processing an order or updating a user profile, often directly in the application layer without complex object models. This pattern is commonly used in simple applications where business logic is not overly complex and can be managed with linear, step-by-step scripts.
Developers should use Transaction Script for small to medium-sized applications with straightforward business processes, as it offers simplicity, quick implementation, and easy debugging due to its procedural nature. It is particularly suitable for CRUD (Create, Read, Update, Delete) operations, batch processing, or legacy system integrations where complex domain modeling is unnecessary. However, it may become cumbersome in larger systems with intricate business rules, where patterns like Domain Model or Service Layer are more appropriate.
