Normalizing Data

What Normalization Means. How To Fix Bad Tables.


 S  M  L  XL  FS  |  Slo  Reg  Fast  2x  |  Bookmark Join Now

In this video we're going to learn about database normalization for Microsoft Access. This is, in a nutshell, making sure that your tables hold the correct types of data to form proper relationships. We will go over some database theory, and then I'll show you how to take a table that holds both customer and order data and normalize it by splitting it into two tables with a proper relationship between them.

Leslie from Harrisonburg, Virginia (a Platinum Member) asks: I'm trying to move my data from Excel to Access. I've watched your video on importing, it was very helpful. Thank you. But what do I do if I've got data mixed together that shouldn't be? For example, I've got one sheet in Excel that mixes customer and order data together. Is there a way to separate it?

Members

Members will look at three more examples of normalizing data. We'll separate customer data by like address fields, we'll take a table that has a parent and multiple children listed together and split that into two tables, and we'll do the same thing for customers with multiple addresses and phone numbers.
