I am looking at using a table to keep track of all my PI Tags and manual entry attributes used in the AF structure. This means I can then reference to the table to get the pi tagname ( to get the value) and a the normal select statement to get the manual attribute value in my elements. I will be doing it for a large number of elements. Will this have a huge impact on performance of the AF Server? Just feels like an easier way for system maintenance if I have everything in one space to manage.
