UBB.Developers Forums UBB.threads 7 Development How Do I? Best way to integrate user table

One way to do it IMHO is to use the w3t_Users table as you mentioned and obtain the information from there. If your custom application is able to read the cookies that .threads sets then you will be able to login in both areas with one login. Now retrieving data from the w3t_Users table will be simple select queries which you would have done either way through the board.

When you are talking about the application being intensive you are talking about using the information stored in the w3t_Users table or in general in the other tables? In .threads the tables that get the most "hammering" are the w3t_Posts, w3t_Last and w3t_Online since they are constantly used when users browse and post the forum.

You can use the w3t_Users table either by having the tables of the custom application in the same database as .threads or you can have them in separate databases, provided that you give the second database user access to the w3t_Users table. That will be a better solution IMHO since MySQL will keep resources separate towards the two applications.

Finally you might be looking at replicated servers but I say that reluctantly since I don't know what you mean by "intensive"

I hope this helps
