From Transaction Scripts to Accommodation Meta Data and Price Calculation Modules — Improving Exhibition Architecture (2/3)

The existing Transaction Script approach had the limitation that business logic was concentrated in a single massive function, resulting in high code complexity and difficult maintenance.

To address this, we carried out an architecture improvement that separated responsibilities into Meta Data, which handles accommodation information, and a Price Calculation Module, which handles complex logic.

The key improvements are as follows:

• Separation of Concerns: Increased code cohesion by separating data management from business logic.
• Modularization: Organized core logic such as price calculation into independent modules, securing reusability and ease of testing.
• Improved Maintainability: Minimized the impact of logic changes on the overall system and improved code readability.
