Refer to the exhibit.

A data architect has a data model that includes historical order fulfillment centers. The order fulfillment centers occasionally changed location. The history of order fulfillment must be tracked on a per center, per location basis.

Which scripting function should the data architect use to meet this data modeling requirement?

Show Suggested Answer Hide Answer
Suggested Answer: C

In this scenario, the data architect needs to track the history of order fulfillment centers on a per center, per location basis. This means that the data architect needs to match the historical order fulfillment center data with the current order fulfillment center data, based on the center and location.

The ApplyMap function allows you to create a mapping between the data in one table and the data in another table, based on a common field. The data architect can use ApplyMap to create a mapping between the historical order fulfillment center data and the current order fulfillment center data, based on the center and location fields.

C) ApplyMap? Nah, that's not going to cut it. We need a function that can handle the temporal aspect of this data model.

D) Inner Join seems like the obvious choice here. We need to link the order fulfillment data to the location data to get the full picture.
