1. First exercise : How to integrate data ?
For example : We have two different data set, X and Z.
We look at the first dataset X :
A simplified bookstore data (dataset “X”)
Next, change the Dataset X into a set
of relations. I have a sample for you.
Then, we have another bookstore data (Dataset
“Z”)
Now, your turn to change the Dataset Z
into a set of relations.
Now, your turn to change the Dataset Z
into a set of relations.
2. Second exercise :
Model the following ontologies into set of relations :
- Herbivores, Carnivores,
and Omnivores are animals
- People are omnivores
- People have names of
type “string”
- Vegetarians are people
who are herbivores
- “eats” is a property of
animals and the values of the property must be of the type “food”
- Meat and Veggies are types of food
