1st table'sFormat is like this: Book_Index Translation1 Translation2 ... Translation5 <Integer> <Memo> <Memo> <Memo> There are total 40,000 records x above 6 fields. Number of Translations are always fixed and equal for each record, not variable. Importances of each Memo are equal. In my Form & Report, I will output both format: 1. Index + Single Translation 2. Index + Multi Translation 2nd Format: Break 1st table into 5 tables (One index with one translation only - 2nd Format) For 1st Format, it is good for later multi-Translation output, since I only need to do index-matching by once, not "multiple". This speed up the operation. But I am not familiar with internal operation of Database & SQL. Will they load WHOLE table during each operation (searching, ...), or just load my assigned fields? If former is the answer, then 1st Table will consume too much memory and may conversely slow down the operation. Then, I can only choose 2nd Table"s" format. N.B. I am using an application similar to MS Access, but it can access one Database in the same moment only. Therefore, all Tables and Forms are always stored in the same file.
