Normalization is the process of creating table designs by assigning specific fields or attributes to each table in a database.
Join based on key fields
A key is one or more fields in a database table which can be used to help identify a particular row of the table. A primary key is one such that uniquely defines a single given row. A foreign key is a set of one or more fields in one table which is the primary key to a row of another table.
When a database table has a key which consists of more than one field, a partial key refers to any one of those fields.

A record in the database is known as a tuple. A record that is identified by a combination of two fields has a composite key.

This is a part of the scope of work that specifies the fields used in the database tables and offers definitions to these fields; their foreign key relationships, etc.
A record identified by 2 or more fields is said to have a composite key.
You can import the field that is the primary key, along with all the other fields. As Excel is not really a database program, it doesn't have quite the same facilities to recognise primary keys. You can still use it as the main field to sort the data on, and also specify other fields to sort on.You can import the field that is the primary key, along with all the other fields.

Any computer based database is composed of certain things in a certain order. The simplest part of a database is the field. Fields can contain pictures or text or sounds or instructions on what to do with other information in other fields. Fields are grouped into Records. Records are the total of all the information on a particular person or item. Records can be combined with other records then to build the database
