Logical types and variants
When you set custom properties in i2 Analyst's Notebook Premium, you need to define logical types and variants to determine the type of data stored in the property.
Usually logical types are defined by your schema, however you override the schema settings when you set custom properties in the import wizard. It is important to select the correct logical type for the data that you would like to store, and the type of analysis that is needed.
These are the logical types you can specify and when you might use them:
| Logical type | Variant | Description |
|---|---|---|
| Text | Single-line string | Use this option for properties such as names or categories. The default length for single-line strings is 250 characters. |
| Multiple-line string | Use for descriptive sections of text, up to 32,700 characters. | |
| Number | Integer | Use Integer for counting numbers. Integers are whole numbers and values can be positive or negative. |
| Double | Use Double for measurements other than financial values. | |
| Decimal | Use Decimal for financial values. | |
| Date & Time | Date & Time | Use for values that occur at a specific instant. The time zone can be selected on the Date & Time Format page. |
| Date | Use for properties where the value is the entire day. | |
| Time | Use for time only values that don't apply to a specific date. | |
| Boolean | Boolean | Use for properties whose values are either "Yes", "No", or "No value". |
