Hi, There are some things that I forgot in my first mail. * there could be some document versions but only the last one should be active, i.e, the other ones souldn't be taken into account for business processes (in a production environment I mean, this does not include other processes like data warehouse). * the date and the one who performed the document transition should be registered. * a document could be identified with: * a code sequentially generated which is document type depending * a barcode which is document type depending. This is very useful for reading documents with barcode readers. I have attached the diagram that represents the data structures into a RDBMS. There were no suggestions :( for my last mail, I hope almost one for this one. Bye. |
