In case of parent-child relationship, how to traverse back and forth?
If by Convention over Configuration/from DAS Config there is a name to a relationship, the opposite relationship is named with _opposite appended to it. e.g. Consider two tables (CUSTOMER, ORDER) each with a PK named “ID”. Also, ORDER has a FK named CUSTOMER_ID. The DAS recognizes this convention and assumes a one:many relationship between CUSTOMER and ORDER. In the fully dynamic case, a read of CUSTOMER and ORDER tables using a join will result in a graph of CUSTOMER DataObjects along with their related ORDERS.(name of relationship is ORDERS now.) The property for the CUSTOMER Types list of ORDERs is named “ORDER” so: DataObject order = cust.getDataObject(“ORDER1”); The name of the property in the ORDER Type that references the parent CUSTOMER, is DataObject cust = order.
