Data properties

Optional properties

Can be missing from the JSON:

• reservationTerm
• effectiveEndDate

Can be empty strings:

• armRegionName
• location
• armSkuName

Natural keys

The combination of the following properties is a natural key (unique) for the Azure Retail Prices items.

• meterId
• meterName
• priceType
• skuId
• tierMinimumUnits

Relationships between properties

These are just the string properties.

Implies:

• meterId ⇒ unitOfMeasure
• productId ⇒ serviceName
• productId ⇒ serviceId
• productId ⇒ serviceFamily
• productName ⇒ serviceName
• productName ⇒ serviceId
• productName ⇒ serviceFamily
• serviceId ⇒ serviceFamily
• serviceName ⇒ serviceFamily
• skuId ⇒ armRegionName
• skuId ⇒ location
• skuId ⇒ productId
• skuId ⇒ productName
• skuId ⇒ skuName
• skuId ⇒ serviceName
• skuId ⇒ serviceId
• skuId ⇒ serviceFamily
• skuId ⇒ armSkuName
• skuId ⇒ reservationTerm

Note that currencyCode property is a constant value based on the currencyCode query parameter. It was excluded from this list since it's not interesting.

Equivalencies:

• armRegionName ⇔ location
• productId ⇔ productName
• serviceId ⇔ serviceName
