With Complete Solutions
QVD Right Ans - Qlik Data File
Can only be written to and extracted by Qlik Sense
Advantages include:
- Optimized loads and compression (10x to 100x) speed compared to CSV
- Incremental loading or snapshotting where needed
- Consolidated data from multiple sources
QVF Right Ans - Qlik Sense application file
Data loading methods Right Ans - 1. data catalog
2. data load editor
3. data manager
Data Catalog Right Ans - Collection of existing data on the app
Loading data with field names Right Ans - Select "embedded field names"
during load preview
Data profiling Right Ans - Par of the Data Manager
When enabled, it will use AI to determine best associations and auto-generate
date/geolocation data
Concatenating tables Right Ans - By default, Qlik Sense will concatenate
tables with the same exact column names
You can undo this in the data manager (tables view) or by adding a script line
NoConcatenate
Box plot Right Ans - 1-2 dimensions, 1 measure
Distribution of measure in the form of a box and whiskers chart
,Qlik DataTransfer Right Ans - Solution that pushes on-prem data to the
cloud in the Qlik SaaS. Qlik can watch the offline folders for updates, re-upload
the data, and apps will automatically update on the platform
Preceding (Stacked) load statements Right Ans - Since you cannot
reference calculated fields in the data load editor unless they have already
been loaded, you need to stack the statements
LOAD ReferenceDate, Age( ReferenceDate, BirthDate ) as Age;
LOAD *, Date(FromDate + IterNo() - 1 ) as ReferenceDate
IF statements Right Ans - If(condition, True, Else)
if you don't include an Else value at the end of the statement, the else
condition will return as Null
Bucketing card (Data manager) Right Ans - Bucketing values will include
the lower bound and exclude the upper bound
You can edit bucket ranges and names in the table editor
Load data to create the new field
Bucketing creates dimensions from measures
Viewing data table metadata Right Ans - Go to data model viewer > click
the table header > view info on number of rows, fields, and keys
Click the table itself shows the number of nulls, distinct values, density, and
subset ratio
Density (data table metadata) Right Ans - Percent of non-null values in
table (100% density means no null)
Circular reference Right Ans - Multiple paths (keys) linking data tables
together, such as in a triangle
This is often due to similar field names, even when content is not the same
, Synthetic key Right Ans - Composite keys that are created in Qlik Sense
when two or more data tables have two or more fields in common
This creates a synthesis of both fields, which should often be avoided. You can
break this key by going into the data manager. Most likely, only one key is
needed
Subset ratio (data table metadata) Right Ans - Present distinct values in the
current table / total distinct values across all tables
Tells you a bit about the importance of a table
Table Editor view features (Data Manager) Right Ans - 1. Configure date
fields
2. Edit associations
3. Add calculated fields
4. Unpivot a table
5. Configure custom associations
6. Transform data
7. Force a concatenation and de-concatenation
Split values card (Data Manager) Right Ans - Split values based on where
you would like each field to be cut. Scroll over the position of the field and
select "these positions"
Good for address fields and composite IDs
If you have a delimiter to split, then select the delimiter and choose 'all
instances'
Replace card (Data Manager) Right Ans - Good for replacing different
naming conventions into one common name.
It's also good for creating custom groupings. You can use this to set nulls as
well
This replaces the actual values in the field
