Keeping two tables in sync

[john9210]

How can I keep two tables in sync? I have two tables, Table1 and Table2. Each table has the field Item and the number of records is the same in each table.
I would like to be able to make changes in one table and have them updated in the other table so that the list of items is the same in both tables. That is, when a record is created, deleted or an item is edited it one table the other table will update to match the changes.

Why do you have duplicate data? The goal of a database is to limit such a state.

OK, I see your point and I will eliminate the need for duplicate data.
