Moving Columns to another table
You often start with a simple database design. Then you recognize that needs grow and requirements are changing. Take our favorite example, Leads Management database – the city is a type-in field. Good for a start, but it is often a source of typing errors and it would be nice to have it as a dropdown list. The simplest way is to switch the City column's Data Entry property from a Type-In to dropdown, but, in this case, only database administrators will be able to maintain the list. And if you want users to be able to edit entries you need to have it in a separate table.
When viewing column's properties you may notice the Move button. Clicking the button will prompt you what to do.
You can either move the column to a new table, or to one of the master tables (the list of options is based on the relationship between tables you already have). Let's start with a new table:
TeamDesk will build distinct list of cities for you, create the new table based on the list and will bind existing leads to a cities table through the relationship. The city name becomes a lookup field.
You may want to go one step further – the state can be used together with the city name in the dropdown thus you can move state column to a city table as well. Since TeamDesk created the relationship between Leads and Cities you have one more choice now:
After confirming the changes and setting up Cities' to display both the city name and state you'll end up with the following user interface:
