If you have to store and retrieve data from a database is a string not the most effcient way? What is best?
How does this work in a real world scenario.
For example: I have a customer ie first name and last name and the CustomerID is autoincremented when initially added to the database. Now, the user could lookup and find the customer by their ID but we all know that's not practical. They don't know 231223 is John Adams, they know John Adams or Adams John.
So how do you handle this? Access is the database I am using but I think this would apply to any database.
