Informix admin and sql

Hello all. Sorry if I am boring anybody but my original question was concerning the following. I am looking into a few technical aspects of an online app that uses Informix as the backend database using the Informix Dynamic Server Version 7.31.UC4X4. I don't really have access to the source code or the latest documentation. I am trying to figure out what tables in the database are affected when a certain transaction or an action generated fro the GUI interface occurs. A few people have responded with great suggestions and thanks to all of them. It appears that one way of knowing know from the actual SQL logged activity. I believe Informix, which CM/ECF runs off of, has a built in utility/tool called Informix System(Server)Administrator that allows you tol easiy isolate current SQL activity, etc, and I think there is a product called I-spy which could be very helpful. Can anyone please elaborate on this if they have had any experience with dealing with those utilities or have had similar tasks to perform and research. If anyone has a few minutes and can help, I would really appreciate it and any feedback is welcome. Thanks sending to informix-list
