# What are Data Types?

Data types are pre-defined data structures that have many different uses. Among them:

- Providing complete objects as inputs for robots
- Providing a structure in which to build data sets
- Providing standardized outputs for robots
- Manipulating data in pipes robots

**Data types and property types**

Data types act as object templates. For example, if you create a *Person* data type, then each *Person* you create will share the same properties of the same types:

Properties in a data type can be of the following:

- Text
- Number
- True/False
- Multiple choice
- Object

Any property can also be defined as a *list*. Setting a property as a *list* tells us that the property accepts more than one value, that is to say, it is a list of values of the type given.

We defined ID as being a *key*. This means that the ID property is unique, so when there are multiple *Person* objects in a data set, each person will have a unique ID.

In this example, a *Person* data type contains an *id*, *firstName* and *lastName* text values. Each *Person* will also have an *age* property which has to be a number; attempting to assign it a value that is not a number will result in the value not being assigned. Each *Person* also has a *europeanCitizen* property which can either be true or false.

Multiple choice values act as text values, but are restricted to the choices given when creating the data type; in this example, gender can only be the text *male* or *female*.

Objects are groups of properties that can be nested indefinitely. In this example, a *Person* can have multiple *socialMedia* objects, with each *socialMedia* object consisting of a *service* and an *accountOrId* property. Objects can also contain objects inside of them.
