This single app is composed of 4 parts

FormCustomerListing: it’s the main UI of the ERP. It gives you the possibility to add or update a “customer” (fields = name).

MyDatalayer : it’s the Layer of the ERP. The logic to add, update, get or list ERP Customer is there. The only table managed is the table “customer”

SyncWithAPI : it’s the core logic of the Sync with the API (from API or to API).

SyncDbLayer : it’s the layer used by SyncWithAPI to store some settings needed (sync_settings) and also to store a cache of the object (sync_cache) to verify if they have been changed or not.
