I have seen this problem a few times and never can come up with a solution i like.
System A Sales Order Entity order_id created line_items_count System B Sales Order Entity sales_order_id created_At num_line_items
The problem is, that sales orders are created in System A - for example an e-commerce website. The sales orders need to be exported and stored in another system, for example a warehouse system - System B. They both store the same data but under different field names.
Is there a design pattern or collection of patterns typically used to solve such problem?
I always end up with an associative array containing the mapped fields - but it feels like there must be a better solution.
In the example above, not only sales orders might require this, also customers, products, inventory levels etc - so a generic pattern would be best.
