Creating Time Filters

Atomic metrics are standard definitions for computing logic. Time filters are standard definitions for conditional limits. To ensure that all statistical metrics are unified, standard, and unambiguous, time filters must be unique within a business domain and each filter can belong to a single source logic table. The computing logic is defined based on the fields of the source logic table model. A time filter may come from multiple logic tables that belong to different data domains. Therefore, a time filter may belong to multiple data domains as well.
