[Koha] how does koha save data

[Octavee Uhl]

Hello Joe,

thanks so much for this info. How do I find out if that indexing is
scheduled?
Just to be sure, when I enter a change in the homebranch via MySQL and
rebuild the index it will be correct and reflect in both views? 
I am ware that the koha intranet gives a certain security and I don't want
users to mess with the data, but for me as the main Administrator I need to
understand how things do work and sometimes interact via mysql.

I want to wait until version 3 is stable and running fine before changing
the system to version 3.
