Hi budThere is only one image file for each signature. Yes, actually I am going to design one table to put all of the data in, which is exactly the same as your design idea. However, my problem here is how to create a mapping schema to do so. I tried many times and encountered some error messages. I solved some, but still debugging and don't know how far i need to go to have it done. What i am doing now is i download a software called 'ms xml viewer', which looks pretty good. However, i am not familiar with it and play with it at the moment. But it seems only help you to create a schema based on either a database table, or a xml data file. In order to create a well-matched mapping schema to both of my database table and xml file, i still have no idea to do. I am really a newbie, amn't I? Hopefully, you or someone xml pro can give me advice. Many thanks. Btw, glad to see your reply. Cheers
