Every piece of information you see here is important. How can we capture this information in a database? Invoice Those of us who have an ordered mind but aren't quite aware of relational databases might decide to use a spreadsheet, such as Microsoft Excel.
But what if you start to ask complicated questions, such as: What are total sales of 56" Blue Freens in the state of Texas? What items were sold on July 14, ? As your collection of invoices grows it becomes increasingly difficult to ask the spreadsheet these questions.
In an attempt to put the data into a state where we can reasonably expect to answer such questions, we begin the normalization process. These represent all the data we have for a single invoice Invoice Never mind the fact that one database row is made up here of three spreadsheet rows: It's an unfortunate ambiguity of language.
Academic database theoreticians have a special word that helps a bit with the ambiguity: We're not going to use that word here and if you're lucky, you'll never hear it again for the rest of your life. Here, we will refer to this thing as a row.
Again we turn our attention to the first invoice in Figure A This is a column within our first database row. You will notice that each of these columns contains a list of values.
It is precisely these lists that NF1 objects to: NF1 abhors lists or arrays within a single database column. Therefore it is clear that we have to do something about the repeating item information data within the row for Invoice On Figure A-1, that is the following cells: We can satisfy NF1's need for atomicity quite simply: We were trying to reduce the amount of duplication, and here we have introduced more!
Just look at all that duplicated customer data! The kind of duplication that we introduce at this stage will be addressed when we get to the Third Normal Form. We have actually only told half the story of NF1. Strictly speaking, NF1 addresses two issues: A row of data cannot contain repeating groups of similar data atomicity ; and Each row of data must have a unique identifier or Primary Key.
We have already dealt with atomicity. But to make the point about Primary Keys, we shall bid farewell to the spreadsheet and move our data into a relational database management system RDBMS. A primary key is a column or group of columns that uniquely identifies each row.
As you can see from Figure B, there is no single column that uniquely identifies each row.Time Management Whatever your expectations for the “total” college experience, planning and sequencing activities is important to your success.
