Таблица календаря для хранилища данных

Для моего хранилища данных я создаю таблицу календаря следующим образом:

SET NOCOUNT ON

DROP Table dbo.Calendar
GO
Create Table dbo.Calendar
(
    CalendarId              Integer NOT NULL,
    DateValue               Date    NOT NULL,
    DayNumberOfWeek         Integer NOT NULL,
    NameOfDay               VarChar (10) NOT NULL,
    NameOfMonth             VarChar (10) NOT NULL,
    WeekOfYear              Integer NOT NULL,
    JulianDay               Integer NOT NULL,
    USAIsBankHoliday        Bit     NOT NULL,
    USADayName              VarChar (100) NULL,
)
ALTER TABLE dbo.Calendar ADD CONSTRAINT
    DF_Calendar_USAIsBankHoliday DEFAULT 0 FOR USAIsBankHoliday
GO
ALTER TABLE dbo.Calendar ADD CONSTRAINT
    DF_Calendar_USADayName DEFAULT '' FOR USADayName
GO

Declare @StartDate  DateTime = '01/01/2000'
Declare @EndDate    DateTime = '01/01/2020'

While @StartDate < @EndDate
Begin
    INSERT INTO dbo.Calendar 
    (
        CalendarId, 
        DateValue, 
        WeekOfYear,
        DayNumberOfWeek,
        NameOfDay,
        NameOfMonth,
        JulianDay
    )
    Values 
    (
        YEAR (@StartDate) * 10000 + MONTH (@StartDate) * 100 + Day (@StartDate), --CalendarId
        @StartDate,                 -- DateValue
        DATEPART (ww, @StartDate),  -- WeekOfYear
        DATEPART (dw, @StartDate),  -- DayNumberOfWeek
        DATENAME (dw, @StartDate),  -- NameOfDay
        DATENAME (M, @StartDate),   -- NameOfMonth
        DATEPART (dy, @StartDate)   -- JulianDay
    )

    Set @StartDate += 1
End

--=========================== Weekends
-- saturday and sunday
UPDATE dbo.Calendar SET USAIsBankHoliday = 1, USADayName += 'Weekend, ' WHERE DayNumberOfWeek IN (1, 7) 


--=========================== Bank Holidays
-- new years day
UPDATE dbo.Calendar SET USAIsBankHoliday = 1, USADayName += 'New Year' Day, '  WHERE (CalendarId % 2000) IN (101)

-- memorial day (last Monday in May)
UPDATE dbo.Calendar 
SET USAIsBankHoliday = 1, 
    USADayName += 'Memorial Day, '  
WHERE 1=1
AND CalendarId IN 
    (
        SELECT MAX (CalendarId)
        FROM dbo.Calendar 
        WHERE MONTH (DateValue) = 5 
        AND DATEPART (DW, DateValue)=2
        GROUP BY YEAR (datevalue)
    )

-- independence day
UPDATE dbo.Calendar SET USAIsBankHoliday = 1, USADayName += 'Independence Day, '  WHERE (CalendarId % 2000) IN (704)

-- labor day (first Monday in September)
UPDATE dbo.Calendar 
SET USAIsBankHoliday = 1, 
    USADayName += 'Labor Day, '  
WHERE 1=1
AND CalendarId IN 
    (
        SELECT MIN (CalendarId)
        FROM dbo.Calendar 
        WHERE MONTH (DateValue) = 9
        AND DATEPART (DW, DateValue)=2
        GROUP BY YEAR (datevalue)
    )

-- thanksgiving day (fourth Thursday in November)
UPDATE dbo.Calendar 
SET USAIsBankHoliday = 1, 
    USADayName += 'Thanksgiving Day, '  
WHERE 1=1
AND CalendarId IN 
    (
        SELECT Max (CalendarId)-2
        FROM dbo.Calendar 
        WHERE MONTH (DateValue) = 11
        AND DATEPART (DW, DateValue)=7
        GROUP BY YEAR (datevalue)
    )

-- christmas
UPDATE dbo.Calendar SET USAIsBankHoliday = 1, USADayName += 'Christmas Day, '  WHERE (CalendarId % 2000) IN (1225)

--=========================== Other named days
-- new years eve
UPDATE dbo.Calendar SET USADayName += 'New Year' Eve, '  WHERE (CalendarId % 2000) IN (1231)

-- black friday (day after thanksgiving day)
UPDATE dbo.Calendar SET USADayName += 'Black Friday, '  WHERE CalendarId IN (SELECT CalendarId+1 From dbo.Calendar Where USADayName like '%Thanksgiving%')

-- christmas eve
UPDATE dbo.Calendar SET USADayName += 'Christmas Eve, '  WHERE (CalendarId % 2000) IN (1224)

-- boxing day
UPDATE dbo.Calendar SET USADayName += 'Boxing Day, '  WHERE (CalendarId % 2000) IN (1226)

--=========================== Remove trailing comma
UPDATE dbo.Calendar SET USADayName = SubString (USADayName, 1, LEN (USADayName) -1) WHERE LEN (USADayName) > 2

SELECT * FROM dbo.Calendar

Вот вывод этой команды

Я видел аналогичные структуры, реализованные в разных вариантах архитекторами данных.

Мой вопрос: какую дополнительную информацию о хранилище данных/размерном стиле можно добавить в эту структуру таблицы?
