Database – First Normal Form (1NF)
The First normal form (1NF) sets basic rules for an organized database:
Define the data items required, because they become the columns in a table.
Place the related data items in a table.
Ensure that there are no repeating groups of data.
Ensure that there is a primary key.
First Rule of 1NF
You must define the data items. This means looking at the data to be stored, organizing
the data into columns, defining what type of data each column contains and then finally
putting the related columns into their own table.
For example, you put all the columns relating to locations of meetings in the Location
table, those relating to members in the MemberDetails table and so on.
