I would like some help and advice on how to model my entities using JDO on GAE. My problem is this, I have a bunch of Users and each User may create zero or more Tracks. Users may exist without a Track but Tracks may not exist without a User who created them. Other attributes on the User and the Track may updated. I would like to be able to query the Tracks and retrieve some attributes from the User who created the Track. The attributes from the User may get updated. In SQL this would be
select u.displayName, t.trackName from User u, Track t, where t.userId=u.userId I have some ideas and have tried various things but this isn't a post on why doesn't something work, more of what is the best practice to solve this problem. thanks <M -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
