Below is a detailed reference table with all the fields related to attribute.

| Field                 | Detailed Definition                                                                                                                                                                                                                                                                   |
| :-------------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Alert**             | The count of active, unresolved alerts triggered specifically on this attribute — for example, when a value, threshold, or anomaly detection rule fires for that column. A higher count signals the column needs immediate attention.                                                 |
| **Blank Count**       | The number of rows where this attribute's value is a blank/empty string (`""`) rather than null. Distinct from Null Count — blanks are present but contain no characters, often indicating upstream data entry issues.                                                                |
| **Created At**        | The timestamp marking when this attribute was first discovered and cataloged by Prizm, typically aligned with when the parent table or column was created at the source.                                                                                                              |
| **Criticality**       | The business-impact classification assigned to this specific attribute (e.g., Critical, High, Medium, Low) — independent of the parent table's criticality, since individual columns can carry different levels of business sensitivity (e.g., a PII field vs. a metadata timestamp). |
| **Criticality Score** | The underlying numeric score (typically 0–100) that determines the Criticality label. Calculated from factors like usage, dependency, and metadata completeness specific to this column.                                                                                              |
| **Data Type**         | The native data type of the column as defined in the source system (e.g., `NUMBER`, `TEXT`, `BOOLEAN`, `DATE`, `TIMESTAMP_LTZ`). Determines what types of profiling statistics (e.g., Min/Max Value vs. Min/Max Length) are applicable.                                               |
| **Description**       | The business or technical description written for this attribute, explaining what the column represents and how it should be interpreted or used.                                                                                                                                     |
| **Distinct Count**    | The number of unique values found in the column across all evaluated rows. Useful for assessing cardinality — low distinct counts on an expected unique key (like an ID) may indicate a data quality problem.                                                                         |
| **Empty Count**       | The number of rows where the attribute's value is empty (no content at all), distinguished from Blank Count and Null Count depending on how the source system differentiates them.                                                                                                    |
| **Issue**             | The count of open, logged data quality issues specifically tied to this attribute — typically created when an alert is escalated or manually flagged for investigation and resolution.                                                                                                |
| **Max Length**        | For text-type attributes, the maximum character length observed across all values in the column. Helps detect truncation risks or unexpected long-form data.                                                                                                                          |
| **Max Value**         | For numeric or date-type attributes, the highest value observed in the column. Useful for spotting outliers or out-of-range data.                                                                                                                                                     |
| **Metric Count**      | The total number of data quality/observability metrics actively configured and tracked on this attribute (e.g., completeness, uniqueness, freshness checks). A higher count generally indicates more thorough monitoring coverage.                                                    |
| **Min Length**        | For text-type attributes, the minimum character length observed across all values in the column. Helps detect unexpectedly short or incomplete entries.                                                                                                                               |
| **Min Value**         | For numeric or date-type attributes, the lowest value observed in the column. Useful for spotting negative values, zero anomalies, or out-of-range dates.                                                                                                                             |
| **Null Count**        | The number of rows where this attribute's value is `NULL` (no value recorded at all, as opposed to blank/empty). A key completeness indicator.                                                                                                                                        |
| **Primary Key**       | A boolean flag indicating whether this attribute serves as (or is part of) the primary key for its parent table — i.e., whether it uniquely identifies each row.                                                                                                                      |
| **Qualified Name**    | The full hierarchical path that uniquely identifies this attribute within the platform, typically structured as `Database / Schema / Table / Column`.                                                                                                                                 |
| **Row Count**         | The total number of rows evaluated when calculating this attribute's statistics — generally matches the parent table's row count at time of profiling.                                                                                                                                |
| **Score**             | The overall data quality score for this specific attribute, expressed as a percentage, derived from the combined results of all metrics and tests configured on it.                                                                                                                   |
| **Space Count**       | The number of values in the column that consist only of whitespace characters (spaces, tabs) rather than meaningful content — often an indicator of dirty or improperly cleaned source data.                                                                                          |
| **Status**            | The workflow/review status of the attribute within Prizm's governance process (e.g., `Pending`, `Ready for Review`, `Approved`), reflecting whether it has been reviewed and documented.                                                                                              |
| **Test Count**        | The number of explicit data quality tests (e.g., not-null, uniqueness, accepted-values) configured specifically on this attribute, separate from passive observability metrics.                                                                                                       |
| **Zero Values**       | A boolean/indicator flag showing whether zero values are present in this numeric column at all.                                                                                                                                                                                       |
| **Zero Values Count** | The exact count of rows where this numeric attribute's value equals zero — useful for distinguishing legitimate zero entries from missing or default-filled data.                                                                                                                     |
