As a result, these questions will not appear in the review screen.You have the following line-of-business solutions:✑ ERP system✑ Online WebStore✑ Partner extranetOne or more Microsoft SQL Server instances support each solution. Each solution has its own product catalog. You have an additional server that hosts SQLServer Integration Services (SSIS) and a data warehouse. You populate the data warehouse with data from each of the line-of-business solutions. The data warehouse does not store primary key values from the individual source tables.The database for each solution has a table named Products that stored product information. The Products table in each database uses a separate and unique key for product records. Each table shares a column named ReferenceNr between the databases. This column is used to create queries that involve more than once solution.You need to load data from the individual solutions into the data warehouse nightly. The following requirements must be met:✑ If a change is made to the ReferenceNr column in any of the sources, set the value of IsDisabled to True and create a new row in the Products table.✑ If a row is deleted in any of the sources, set the value of IsDisabled to True in the data warehouse.Solution: Perform the following actions:✑ Enable the Change Tracking for the Product table in the source databases.✑ Query the CHANGETABLE function from the sources for the updated rows.✑ Set the IsDisabled column to True for the listed rows that have the old ReferenceNr value.✑ Create a new row in the data warehouse Products table with the new ReferenceNr value.Does the solution meet the goal?
