Lets say there is a relationship between Entities A and B, and I want to model it with Entity C.
Two ways: 1. Use concatenated Key of A and B for Key of C. Data model will ensure there are no duplicates. 2. Use autogenerated Key and make sure you do not duplicate A B relationship in code. Which one would you choose? In 1, is a simple concatenation the best way to go about it? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
