You are designing a data warehouse for a software distribution business that stores sales by software title. It stores sales targets by software category. Software titles are classified into subcategories and categories. Each software title is included in only a single software subcategory, and each subcategory is included in only a single category. The data warehouse will be a data source for an Analysis Services cube.
The data warehouse contains two fact tables:
-> factSales, used to record daily sales by software title
-> factTarget, used to record the monthly sales targets by software category
Reports must be developed against the warehouse that reports sales by software title, category and subcategory, and sales targets.
You need to design the software title dimension. The solution should use as few tables as possible while supporting all the requirements.
What should you do?
- A. Create three software tables, dimSoftware, dimSoftwareCategory, and dimSoftwareSubcategory and a fourth bridge table that joins software titles to their appropriate category and subcategory table records with foreign key constraints. Direct the cube developer to use key granularity attributes.
- B. Create three software tables, dimSoftware, dimSoftwareCategory, and dimSoftwareSubcategory. Connect factSales to all three tables and connect factTarget to dimSoftwareCategory with foreign key constraints. Direct the cube developer to use key granularity attributes.
- C. Create one table, dimSoftware, which contains Software Detail, Category, and Subcategory columns. Connect factSales to dimSoftware with a foreign key constraint. Direct the cube developer to use a non-key granularity attribute for factTarget.
- D. Create two tables, dimSoftware and dimSoftwareCategory. Connect factSales to dimSoftware and factTarget to dimSoftwareCategory with foreign key constraints. Direct the cube developer to use key granularity attributes.
Answer : C
You are developing a SQL Server Integration Services (SSIS) package.
The package uses custom functionality that accesses a SQL Server database. The custom functionality must be implemented by using Language Integrated Query (LINQ).
You need to ensure that the LINQ code can be debugged at design time.
What should you select from the SSIS Toolbox? (To answer, drag the appropriate item to the correct location in the answer area.)
Answer :
You are developing a SQL Server Integration Services (SSIS) package that imports data into a data warehouse. You add an Execute SQL task to the control flow.
The task must execute a simple INSERT statement. The task has the following requirements:
The INSERT statement must use the value of a string package variable. The variable name is StringVar.
The Execute SQL task must use an OLE DB Connection Manager.
In the Parameter Mapping tab of the Execute SQL task, StringVar has been added as the only parameter.
You must configure the SQLStatement property of the Execute SQL task.
Which SQL statement should you use?
- A. INSERT INTO dbo.Table (variablevalue) VALUES ($StringVar)
- B. INSERT INTO dbo.Table (variablevalue) VALUES (0)
- C. INSERT INTO dbo.Table (variablevalue) VALUES (@0)
- D. INSERT INTO dbo.Table (variablevalue) VALUES (?)

You are developing a SQL Server Integration Services (SSIS) package that imports data from a relational database to a data warehouse.
You are importing data from a relational table named Projects. The table has change data capture enabled on all columns.
You need to process only the most recent values from rows that have been inserted or updated since the previous execution of the package.
Which query should you use as the data source?
- A. Option A
- B. Option B
- C. Option C
- D. Option D
