How to update old DB to New DB?
sweetummy,
You are STILL to focused on the report and not paying attention to the tables. Think of it like this... Completed Database = House Tables = Foundation Queries = Rooms Reports = Decor You are so focused on the *Decor* that you don't realize you have built your *House* on a POOR *Foundation*. So you need to refocus on the *Foundation*. You have redundant fields (same fields showing up in more then one table). That goes against normalization. So PLEASE go over the table set-up and either redo or explain why you feel need redundant fields/data in more then one place. Why is StudentID in the Areas tables when it will relate back to Students table via the AreaID? As a side note, stop using your reall eMail address or you will get alot of unwanted mail.

Hi, I must thank all of the great guys over here..supporting me right from the intial stage.. I read tutorials regarding to your links given, they are simply amazing and very helpful.. Coming to my database I have cut down all the tables according to report demands.. 1. We need reports according to the student id, by their course and by their area they which belong by the academic year. I understand that, the data should not be redundant should be unique and should be related to each other table what we have logically in our database and according to our demands.. So i have reduced to 3 tables.. namely 1. tbl_StudentDetails 2. tbl_courseDetails 3. tbl_AreaDetails please look at this relationship and their fields in it.. i have taken.. I thought a student is studying a so and so course and belong to so and so area, here the only key is Student id so i make it as a primary key and auto key column is the primary key for all these three tables i have taken over here... http://sites.google.com/site/gsvfilm...attredirects=0 thank you once again. |
