• RecordID is the primary key to the table.
• ProductID is the obsolete name for the field SeriesID. It will be removed after January 1, 2019
• SeriesID is the foreign key to UDM_Catalog_Series, i.e. it uniquely identifies which time series is the value for.
• AreaID is the foreign key to UDM_Catalog_Areas, i.e. it uniquely identifies which geographic area is the value for.
• ReportPeriod is the date for which the value is published. All data in the Value.Quarterly table has ReportPeriod in the format YYYY-[03, 06, 09, 12]-01, where 03 indicates the first calendar quarter, etc.
• CollectionDate is the date on which the report containing the data point has been published.
• Value is the numeric value of the record.
• SourceID is the foreign key to UDM_Catalog_Sources. Since each SourceID belongs to only one ReportID, this field determines to which report the record belongs.
