In our application we have a requirement of changing the relationships between tables i.e. entities dynamically based on transactions. The scenario is described below:
There are 3 entities A, B and C available in the system. A is related to B and C in the database with foreign key. In transaction 1 the entities A and B are related and have to be fetched together for these 2 entities only. In transaction 2 A and C are only required but not B. Currently we are using Hibernate as the data access framework. Since the relationships have to be provided on static XMLs and cannot be changed later the system is retrieving the records of C also. Hence we are looking for the right Data Access framework to enable this functionality of changing relationships between entities at runtime. Please let us know whether OpenJPA supports this feature since I am not able to obtain much information from the documentation regarding this.
