Hello, I don't think there's any reason you should use arrays. You can do everything using tables, and it probably would be easier to use tables instead. Extracting information from arrays is also more difficult if you're using something like JDBC or the connectivity available in PHP. I don't know the criteria of when arrays are necessary, but I cannot think of an example where arrays are absolutely necessary Regards, Yasir
