the File object should have an array of document ID's. Your FileDAO would create the associations during a save (create/update). You can split that out into separate functions if you wish, but they should be private and only called from within the DAO.
Helps? -Dave >>> [EMAIL PROTECTED] 02/13/06 2:11 PM >>> So, I have a document section on an intranet (documents & forms). For each form you upload X number of files (client specifications). I am working on my first OOP project and I am feeling a bit overwhelmed. A little advice here would be appreciated. I have a Document object (gateway, BO, DAO, Bean) and I have File objects (gateway, DAO, Bean). The sytem is being built so that one file could potentially be linked to more than one document. This is modeled in the join table: File_item_jn (id, file_id, foreign_table, foreign_key). Right now, my FileDAO has the standard CRUD operations that act on the file bean, but I have also thrown in a few methods for Assocations: CreateAssociation(FileBean, ForeignTable, foreignKey) DeleteAssociation(FileBean, ForeignTable, foreignKey) DeleteAssociations(ForeignTable, foreignKey) Is this a bad idea? I feel like these are File-Data-related items, but am new, and not sure if DAO should have anything outside the CRUD methods? Not sure how I feel about this, any advice, suggestions would be super appreciated. ......................
