Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this sections, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You have the following line-of-business solutions:
* 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.
One or more Microsoft SQL Server instances support each solution. Each solution has its own product catalog.
You have an additional server that hosts SQL Server 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:
* Enable the Change Tracking for the Product table in the source databases.
* Query the cdc.fn_cdc_get_all_changes_capture_dbo_products function from the sources for updated rows.
* Set the IsDisabled column to True for rows with the old ReferenceNr value.
* Create a new row in the data warehouse Products table with the new ReferenceNr value.
Solution: Perform the following actions:
Does the solution meet the goal?
You have a data warehouse named DW1.
InDvfe you plan to create a table named Tablel that will be partitioned by hour. Tablel will contain the last three hours of data.
You plan to implement a sliding window process for inserting data into Tablel.
You need to recommend the minimum number of partitions that must be included in Tablel to support the planned implementation. The solution must minimize the number of transaction log records created during the insert process.
How many partitions should you recommend?
You have a database named DB1 that contains millions of rows.
You plan to perform a weekly audit of the changes to the rows.
You need to ensure that you can view which rows were modified and the hour that the modification occurred.
What should you do?
You have a Microsoft SQL Server Integration Services (SSIS) package that includes a custom Script task. You set a breakpoint at line 97 as shown in the exhibit. (Click the Exhibit tab.) C# Methods
You run the code and the debugger pauses at line 97.
You need to debug the ConvertToString method.
What should you do?
You are designing the data warehouse to import data from three different environments. The sources for the data warehouse will be loaded every hour.
Scenario A includes tables in a Microsoft Azure SQL Database:
* Millions of updates and inserts occur per hour
* A periodic query of the current state of rows that have changed is needed.
* The change detection method needs to be able to ignore changes to some columns in a table.
* The source database is a member of an AlwaysOn Availability group.
Scenario B includes tables with status update changes:
* Tracking the duration between workflow statuses.
* All transactions must be captured, including before/after values for UPDATE statements.
* To minimize impact to performance, the change strategy adopted should be asynchronous.
Scenario C includes an external source database:
* Updates and inserts occur regularly.
* No changes to the database should require code changes to any reports or applications.
* Columns are added and dropped to tables in the database periodically. These schema changes should not require any interruption or reconfiguration of the change detection method chose.
* Data is frequently queried as the entire row appeared at a past point in time.
All tables have primary keys.
You need to load each data source. You must minimize complexity, disk storage, and disruption to the data sources and the existing data warehouse.
Which change detection method should you use for each scenario? To answer, drag the appropriate loading methods to the correct scenarios. Each source 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.
NOTE: Each correct selection is worth one point.
