Hi all, I'm working on a project, it consists of 2 parts: application & framework. The application uses the interfaces of the framework which based on a OODB. Now, my task is to replace the OODB with a relational database. So, I have to do the serialization of the object by myself. I don't know how to design the DBArchive, since I don't know how to deal with the inheritance relation and reference relation between the objects. The DBAchive is different from the TextArchive, the letter is a stream, but the former's storage unit is a record that consists of the object's data members and the field name in the database table. If the recursive model of the boost serialization can process this case? Could you give me any suggestions? Thanks a lot! sjdf
