A project to develop a QlikView application for a customer requires splitting developers into two teams.

One team will focus on developing source database query knowledge to create a reusable data layer.

There are several application-specific business rules for this project. The customer needs to incrementally

accumulate history for the QlikView application over time.

The second team will focus on developing the presentation layer. This team also has data modeling and

scripting expertise, but does not have source database query knowledge.

Which data loading strategy should the developers use on the project?

A. create a series of QVWs that apply the business rules and then binary load them into the presentation layer QVW

B. create the presentation layer QVW and connect directly to the source data and apply the business rules in the script

C. create QVDs of the source data and load them into the presentation layer QVW and apply the business rules in the script

D. create QVDs of the source data, apply the business rules and store a second layer of QVDs, and then load these QVDs into the presentation layer QVW

A customer needs a better understanding of inventory trends over time. However, the source database

contains only the current product inventory levels.

Which technique will take advantage of QlikView capabilities to meet the customer's needs?

B. using a QVD file to store an accumulation of periodic snapshots from the source database

C. using a QVX file to store an accumulation of periodic snapshots from the source database

D. using a QlikView script to store an accumulation of periodic snapshots to an XML file

Refer to the exhibit to the right.

Which technique should a developer use to ensure a Country description is loaded for all Address Book

records?

A. load the Address Book records and perform a Left Join of the Excel data to the Address Book table

B. load the Excel data and then load the Address Book data ensuring the Country Code field has the same name in both tables

C. load the Excel data as a Mapping table and use Applymap with a default mapping value when loading the Address Booktable

A customer has data tables for financial results, staffing, sanitary conditions, and customer satisfaction.

Each table contains a date field and a location lD. Not all dates appear in all tables.

How can a developer create a master calendar that can be used with all the tables?

Designate one of the date fields as the reference Build a calendar spanning the minimum and maximum dates in that table Rename all other date fields to match the reference field Left join the location lD from each table into the calendar table on the date fields Drop the location and date fields from all other tables

Designate one of the date fields as the reference Build a calendar spanning the minimum and maximum dates in that table Rename all other date fields to match the reference field Create a link table with a key of Location and date that contains all unique locations and dates Create a key of location and date in the other tables

D. Find the minimum and maximum dates spanned by all tables Create a calendar spanning those dates Create a link table with a key of location and date that contains all unique locations and dates Create a key of location and date in the other tables Drop the location and date fields from all other tables
