Metric lineage

Area	Description
①Search	Supports searching for expanded nodes on the current page based on field name keywords. You can click the left/right arrows after the search box or use the keyboard arrow keys to quickly switch between selected nodes. The system defaults to positioning at the first matching node.
②Legend	Displays the hierarchy levels of the current asset, including business systems (i.e., data source tables, custom metric systems), data collection layer (i.e., source layer), data transformation layer (i.e., intermediate layer, logical table/modeling metric systems), application data layer (i.e., application layer), DataService Studio, report application layer, and common layer.
③Lineage diagram display	Displays the complete lineage chain diagram, allowing manual expansion of multiple levels upstream or downstream. Supports fuzzy search based on field name keywords. Specifically, if there is a circular dependency, further expansion is not possible, and you need to continue viewing downstream from the starting node. Central node: Displays the name of the current metric and is identified with Current Metric in the upper left corner of the node. Metric details: Hover over a node to view metric details, including the metric's type, name, asset source, table, statistical granularity, catalog, asset tags, and description. Specifically, the central node does not display metric details. Note Only metrics that are listed, for which you have viewing permissions, and that have lineage enabled in asset editing support viewing lineage relationships. You can click a metric name to navigate to its details page to view lineage relationships. You can click the name of a metric's table to navigate to the asset details page to view lineage relationships. Node connections: If assets have cross-layer dependencies, they are represented by solid lines. If an asset has self-dependency, it is represented by a dashed line.

Quality overview

Area	Description
①Quality score radar chart	Displays the quality characteristics radar chart, overall quality score, and verification passed rules/scoring rules for the current metric. Six-characteristic radar chart: Hover over a quality characteristic name to view its quality score. Overall quality score: Statistics for the most recent run of created and completed rules corresponding to the current field. The calculation formula is: `Quality score = sum(each rule weight × that rule's quality score) / sum(each rule weight)` Verification passed rules: The total number of rules that participate in quality score calculation for the current metric and whose most recent verification status is passed. Scoring rules: The total number of rules that participate in quality score calculation for the current metric.
②Score list	Displays the quality characteristic assessment details for the current metric, including assessment dimension, quality score, verification passed rules/scoring rules, pass rate, and number of table-level and field-level rules. Quality Score: Based on the most recent run status of rules that participate in quality score calculation for the current metric and whose rule classification includes the corresponding assessment dimension. The calculation formula for rules in a specified assessment dimension is: `Quality score = sum(each rule weight × that rule's quality score) / sum(each rule weight)` Verification passed rules: The total number of rules created for the current metric whose rule classification includes the corresponding dimension, that participate in quality score calculation, and whose most recent verification status is Passed. Scoring rules: The total number of rules created for the current metric whose rule classification includes the corresponding dimension and that participate in quality score calculation. Pass rate: The percentage of `verification passed rules/scoring rules`.
③Rule verification details	Rule verification details need to be enabled on the edit page of manually listed table assets. You can specify a date to view rule verification details, quickly filter Abnormal Results, filter by verification status, or search by rule name keywords. For custom metrics, the statistics include verification records from the last 30 days of completed executions of monitoring rules created for the metric's source field, which are calculated based on the rule scoring method and verification results. For modeling metrics, the statistics include verification records from the last 30 days of completed executions of monitoring rules created with the metric as a Metric and as a regular field of its table, which are calculated based on the rule scoring method and verification results.
