1.1.5. Data Structure
We have several possibilities how to structure data. We can arrange the data in different orders:
|
 |
|
 |
|
 |
- etc.
In the last chapter we presented you four possibilities to store data. But we did not say much about the structure of these storage types. The following list summarises the structure and organisation of the four storage types. By clicking on the thumbnails you get an enlarged example of each type.
Exercise
You have a dataset with private data of various persons. For each person
the following attributes are given: first name, last name, street, number,
postal code, city, birthday, sex, telephone number, e-mail address, country,
marital status, number of children, and nationality.
We
want you to structure and group this data. Create a data schema (sketchily)
which shows the structure of the data. Give reasons why you have chosen your
structure. Choose a storage type that is suitable to the created data
structure.
Hand in your data schema with your
explanations to your tutor.
