Is there a design pattern which covers the following scenario when interfacing with an external system.
- Ecommerce orders placed in system A
- Order need to get to system B which stores the order in a set of database tables using different field names as System A
- Orders need to periodically get exported from system A to system B
- Order updates are fetched from system B and updated in system A periodically
- Data should be validated and errors/success events logged
