Relationship Database
I created a table called pet database with 7 columns/fields. ID is the primary key. On
Postcode I used an Input mask to validate the information inputted into the table. The
datatypes for Name, Address, Postcode, Pet Name and Pet Type are text but as for age is
a number as it only uses numbers. This is a relational Database.
An entity is any object in the system that we want to model and store information about.
Entities are usually recognizable concepts, either concrete or abstract, such as person,
places, things, or events which have relevance to the database. The first entity is owner
and the second is the pet.
I’ve added 3 records to my table
The problem is that information is duplicated

Relationship Database
I created a 2nd
table and created a Primary Key. I then linked a foreign ID with the owner
ID to make a relationship between each table
I added a form to be able to easily add a new Owner to the list

Relationship Database
I created multiple databases that display a certain type of information
This also works for owner ID’s
I have created a report which displays the information of my “Pets Aged over 12”
