  Hi I have a table that needs to be incorporated into the data warehouse.

  The table has the following schema.

  CREATE TABLE [dbo].[Consignment](

  [Id] [int] IDENTITY(1,1),

  [BooingID] INT

  [BookingDate] [datetime] NULL,

  [CarrierServiceName] [nvarchar](255) NULL,

  [CarrierServiceCode] [nvarchar](255) NULL,

  [OriginAddressCompanyName] [nvarchar](255) NULL,

  [OriginAddressAddressLine1] [nvarchar](255) NULL,

  [OriginAddressAddressLine2] [nvarchar](255) NULL,

  [OriginAddressAddressLine3] [nvarchar](255) NULL,

  [OriginAddressTownOrCity] [nvarchar](255) NULL,

  [OriginAddressCountyOrState] [nvarchar](255) NULL,

  [OriginAddressPostcode] [nvarchar](255) NULL,

  [OriginAddressCountry] [nvarchar](255) NULL,

  [OriginAddressCountryCode] [nvarchar](255) NULL,

  [OriginAddressThreeLetterCountryCode] [nvarchar](255) NULL,

  [OriginAddressThreeDigitCountryCode] [nvarchar](255) NULL,

  [OriginContactTitle] [nvarchar](255) NULL,

  [OriginContactForename] [nvarchar](255) NULL,

  [OriginContactSurname] [nvarchar](255) NULL,

  [OriginContactTelephoneNumber] [nvarchar](255) NULL,

  [OriginContactMobileNumber] [nvarchar](255) NULL,

  [OriginContactEmailAddress] [nvarchar](255) NULL,

  [DestinationAddressCompanyName] [nvarchar](255) NULL,

  [DestinationAddressAddressLine1] [nvarchar](255) NULL,

  [DestinationAddressAddressLine2] [nvarchar](255) NULL,

  [DestinationAddressAddressLine3] [nvarchar](255) NULL,

  [DestinationAddressTownOrCity] [nvarchar](255) NULL,

  [DestinationAddressCountyOrState] [nvarchar](255) NULL,

  [DestinationAddressPostcode] [nvarchar](255) NULL,

  [DestinationAddressCountry] [nvarchar](255) NULL,

  [DestinationAddressCountryCode] [nvarchar](255) NULL,

  [DestinationAddressThreeLetterCountryCode] [nvarchar](255) NULL,

  [DestinationAddressThreeDigitCountryCode] [nvarchar](255) NULL,

  [DestinationContactTitle] [nvarchar](255) NULL,

  [DestinationContactForename] [nvarchar](255) NULL,

  [DestinationContactSurname] [nvarchar](255) NULL,

  [DestinationContactTelephoneNumber] [nvarchar](255) NULL,

  [DestinationContactMobileNumber] [nvarchar](255) NULL,

  [DestinationContactEmailAddress] [nvarchar](255) NULL,

  CONSTRAINT [PK__Consignm__3214EC074707859D] PRIMARY KEY CLUSTERED

  (

  [Id] ASC

  )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY],

  This Table has the same granularity as the fact table as it’s one row per booking.

  However due to the nature of the data I would not want to incorporate this into the fact table.

  The Originating and Destination addresses are populated for each booking and are required for reporting.

  Question

  Should this be moved into a fast changing Dimension table.?

  or would there be a better way to incorporate this data.

  There's different ways to handle this, but if you had a Originating_key and Destination_key columns in your fact table, you would have to deal with changing dimensions.
