Data types

Discover the different types of data and their specificities to perform the desired actions on your database.
The data contained in a database is organized according to a consistent set of principles. Each database has its own schema and different data types. 
Although there are several database models, the types are standardized and allow you to define what the database contains, even before describing its elements. For example in a news application, there is a data type Text for the title of the article, a data  of type Image  for the illustration photo etc...   
Defining the type has important consequences on how you can use the data when building your application, or operate on the data. Data of type Text can be truncated, numbers can be multiplied, addresses can be displayed on a map, etc. 

Primary types

Text 

The Text data type represents a sequence of characters. These characters can be text characters, special characters, numeric characters or punctuation marks.

"3 room flat in Paris"

Number

The Number data type represents integer and decimal values. 

130 000

Boolean

The Boolean data type has 2 values: True or False.

True

Array

The array is a data structure representing a finite sequence of elements that can be accessed efficiently by their position, or index, in the sequence. The index always starts at   0. So the first element is at index  0, the 2nd at index  1, the 3rd at index  2 etc.

["Rosa Bonheur", "Cité des sciences", "Musée du Quai Branly"]

Key / Value

The key-value is an array containing a collection of key-value pairs. The keys can be used to get the corresponding values. The keys must be unique. 

{ "Address": "44 rue des Gravilliers 75003 Paris" }

Collection 

The collection is an array of objects that are referred to as elements. When you create a collection, you choose the structure for each of its elements. For example, if you are creating a collection of real estate, you will probably need a name, a picture of an address, an area, a price, a description and the number of rooms. You can create a field for each type of content - most will be fields of type Text, except for the photo which will be of type Image
