What should you identify for each requirement?

DRAG DROP
You are designing a service layer endpoint named EndPoint1 that will read more than one million rows from a database named DB1, and then update several rows in multiple tables in a database named DB2.
You need to identify a data access strategy that meets the following requirements:
Uses the OData protocol to retrieve data from EndPoint1
Creates a strongly typed object based on the table in BD2
Retrieves data from DB1 as quickly as possible, while minimizing memory use on the application server
What should you identify for each requirement? To answer, drag the appropriate data access strategies to the correct requirements. Each data access strategy may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
