In this table I have showed the author information, since the person how is looking for a book may want to find the author and his biography. Instead of repeating in the first table the names of writers how may have more than one book, another table is very good for redundancy and eliminating the repetition of the author’s name, by using a key foreigner we reduce the data redundancy in the first table.

The referential integrity is defined as any field in the first table that is declared a foreign key can contain only values from the parent table’s primary key second table. On the other hand, if we create a bad keys that does not much in numbers for example we will have difficulties to link the primary key from the first table to the second table.

The benefit of having good designed tables is very important however, without the use of tools to link between them can be a challenge for the users, therefore, creating and transforming these tables in Access will give us many benefits and more organized data by:

1. Creating relationships: these relationships link the tables with each other and create an automatic bridge for the user to flow trough and find his information.

2. Creating Query: that will enable us to select specific information that we want and put it in a separate table.

All these steps are illustrated in the Access data attached
