Data Types and Constraints

When adding customized data types, you can configure different constraints for each data type. Each data type corresponds to different constraints.

Basic Data Type	Constraints
Boolean	None.
Date	You can specify the start date and end date, as well as the date format.
DateTime	You can specify the start date and end date, as well as the date format.
Double	You can specify a range.
Float	You can specify the float range.
Integer	You can specify a range.
Long	You can specify a range.
String	You can specify multiple rules with different conditions. Regular expression is supported. You can combine the following conditions with the String data type: Contains, Starts, Whole, Valid list, and Invalid list. If you want to provide a list of values as the constraint, add a list of invalid values or valid values accordingly.
Time	You can specify the start time and end time, as well as the time format.
