Payment methods conceptual and logical model ...at all but I want to denote that table is used for pricing only when the cost is being calculated, although no relationship is maintained in actual implementation of DB. I'm ordered to deliver conceptual and norm. logical model and in conceptual I cant have isolated entities by the definition-that's what puzzles me.I don't know whether to left out those rate entities completely or keep them somehow in the model.I want to keep tables for prices in DB without any relations to them but I don't know if I can have them isolated in the design.Could you please advise me on how to design the model? |

Payment methods conceptual and logical model Thank you very much Joel, I got your point, you are right. I don't want to keep relationship for the transaction. |
