I have three tables and two data relations connecting them:

(Table 1 -> Table 2 <- Table 3)

I'm using an MS Access database and the primay key column in each table uses a auto number.
The data relations have also been set up to cascade updates and deletes.
At the moment I'm using 3 data adapters to create the tables in the data set which seems to be working

Now I need to add, delete and update records in the database but I'm strugging to find anything useful. Does anyone know of the correct way to do this?
