  * Some data types have special properties that can be accessed in order to change the data type. For example, to get an unsigned integer with zerofill you can do `DataTypes.INTEGER.UNSIGNED.ZEROFILL`.
  * The order you access the properties in do not matter, so `DataTypes.INTEGER.ZEROFILL.UNSIGNED` is fine as well. The available properties are listed under each data type.
