About an Incorta Analyzer Table Column

An Incorta Analyzer table column exists in an Incorta Analyzer Table and is a reference to a physical schema table column or business schema view column.

Properties of an Incorta Analyzer table column

An Incorta Analyzer table column has configurable and static properties. The following are the properties of an Incorta Analyzer table column:

PropertyControlDescription
Column Nameread onlyThe column’s name; used in the fully qualified name of the column
Column Labelread onlyA user-friendly name. The label for an Incorta Analyzer table column is defined in the column properties of the Analyzer.
Column Typeread onlyThe data type of the column. The data type of a column in an Incorta Analyzer table is determined by the source column.
Functiondrop down listSelect the Incorta function of the column
Descriptiontext boxEnter a description of the column
Encrypttoggle (read only)Incorta Analyzer tables do not support encrypted columns. You cannot set this property; it is always false.
Show in AnalyzercheckboxSelect to show as a selectable column in the Data Panel
Data LineagelinkSelect the Lineage link to open the Data Lineage Viewer v2 that displays a diagram with the entities referenced in the respective column (upstream lineage) and entities where the respective column is referenced (downstream lineage).

Type property

As a referenced column, the type property of an Incorta Analyzer table column is an immutable property. If the type property of a physical schema table column is changed, it will affect the referenced column in the Incorta Analyzer table. If the type property is changed to a type that cannot be properly type-casted, you may need to recreate the Incorta Analyzer table.

Function property

The function property of an Incorta Analyzer table column not only determines how the Loader Service stores data for the column, but also influences how tools such as the Analyzer assign a specific behavior to the column. An Incorta Analyzer table column can function as a measure, dimension, or key.

When you create the Incorta Analyzer table, the function of the column is determined by the Analyzer tray you have added the column to (grouping dimension or measure).

Note

If you edit the Incorta Analyzer table and change the column function in the Analyzer, you will need to manually update the column function in the Table Editor.

Function: Dimension

A dimension categorizes, describes, or groups data. Examples of a dimension column are State, Year, or City. Dimension columns do not require unique values.

A dimension column has an associated behavior in the Analyzer. When a user double-clicks a dimension column in the Data panel, the Analyzer automatically adds the column to the Grouping Dimension tray in the Insight panel.

Function: Measure

A measure is a measurement of data. Examples of a measure column are Revenue, Quantity, and Cost.

A measure column has an associated behavior in the Analyzer. When a user double-clicks a measure column in the Data panel, the Analyzer automatically adds the column to the Measure tray in the Insight panel.

Function: Key

Before 6.0.3 On-Premises and 2024.1.2 Cloud releases, an Incorta Analyzer table would not allow the function of an Incorta Analyzer table column or Incorta Analyzer table formula column to be a key. However, starting these releases, you can specify key columns for Incorta Analyzer and SQL tables. Adding, removing, or changing key columns does not require running a load job as derived tables are refreshed as part of schema update jobs. The derived table’s unique index is calculated and saved as a snapshot DDM file each time the key columns are updated or the schema or table is loaded. Make sure that the column or columns that you designate as key ensure row uniqueness; otherwise, loading the derived table might finish with errors.

Encryption property

An Incorta Analyzer table does not support encrypted columns; this property is disabled, and you cannot edit it.

Additional Considerations

Business schema view references

When creating an Incorta Analyzer table, you are able to access the business schema as a data source for an Incorta Analyzer table. There are several cases you should be aware of when utilizing entities in the business schema view as a data source.

Circular dependencies

A business schema view column can reference an Incorta Analyzer table. The same Incorta Analyzer table can reference the same business schema view column. These types of cyclical dependencies will cause errors and should be avoided.

Session variables referenced in business schema

The value of a session variable is calculated at runtime. If an Incorta Analyzer table references a business schema view column that is referencing a session variable, the value of the session variable in the Incorta Analyzer table will be calculated at load time. Avoid making this reference as the session variable’s value may change between a physical schema load.
