[mistar_ti]

Hello, if there is someone who knows the seasons and the different files if there are tables and columns that do not change please share them, I give an example:
User account table = MEMB_INFO
Username = memb___id
Password = mem__pwd .... etc.

You need to give more example of what you want.

The idea is when making webpages to know which names do not change. The others that change to be made as constants.
