Discovering native data types
When no semantic types obtain a result of more than 40%, the data discovery assigns a data type.
| Native data type | Description | Example |
|---|---|---|
| Text | String text | username |
| Integer | Numeric value | 123 |
| Decimal | Decimal numeric value | 1.26 |
| Date | Date including day, month and year | 11/08/2022 |
| Time | Time of the day | 11am |
| Timestamps | Date and time | 11/08 11:00 |
| Boolean | Answers with the value True or False | True |
To determine of which type is a value, the data discovery follows an order:
- Is the value empty?
- Is the value of type boolean? true and false are the only values considered of type boolean.
- Is the value of type integer?
- Is the value of type decimal?
- Is the value of type date?
- If the value is not of one of the above types, it is considered a text value.
As the verification is incremental, a value is only of one type. For example, the value 5 is of type integer. It will not be considered of type text.
