Structured presentation we will utilize.

A straight table is vastly improved at the season of arranging when contrasted with the rotate table as we can sort it as per any section according to our decision. In any case, it isn’t useful for gathering reason.

We can utilize just two measurement

Check outline and rundown box have just articulation and no measurement.

We can utilize macros for different purposes like for reloading the application and to make object.

The layer are fundamentally determined to the sheet object properties format where base, top, typical particular to the number – 1,0 and Experience this canny Infographic to find out about the qualities of QlikView now.

Measurements permit information examination from different points of view.

Very much Structured Form of Data, which doesnt have any reiteration or excess of information. It’s a sort of Relational information. It’s for the most part utilized in OLTP sort of stuffs Denormalized Data – It’s an entire cluster of information with no relationship among themselves, with excess of information. It’s fundamentally utilized in OLAP sort of stuffs.

The least difficult type of dimensional model, in which information is prearranged into certainties and measurements is known as Star diagram.

A snowflake pattern is a distinction of the star blueprint. Snowflake is utilized to enhance the introduction of specific inquiries.

The inner match is prefixes with the heap articulation which is utilized for interfacing diverse numeric qualities to at least one numeric interim.

Interior match work is utilized to create information container of various sizes.

A holder object is utilized to keep numerous graphs. We can utilize a compartment item to keep numerous diagrams in a similar box.

Broadened interim match work() is utilized for gradually changing the measurements.

Holder Object;Granular Chart Dimension Control; Actions like, clear documented; meta data,etc are the new highlights in QV 11.

Join is utilized to change over the given information and at whatever point we are utilizing joins for changing over information its is known promotion Data Merging. It has numerous sorts: Left join Right join Inward join, and so forth

Left join indicates that the join between the two tables ought to be left go along with, it utilizes before the word join. The subsequent table just contain the blend among two tables with the full informational index from the main table. When we have more than one regular field between at least two tables then we have engineered keys.

Right join determines that the join between the two tables ought to be correct go along with, it utilizes before the word join. The subsequent table just contain the mix among two tables with the full informational collection from the second table.

Inward join indicates that the join between the two tables ought to be internal join. The subsequent table ought to contain the full informational collection from both the sides.

Modifiers manages the Fields name. For instance: sum({$}Sales) Returns the deals for current determination, however with the choice in “District” is expelled.

0-Represents the unfilled set 1-Represents the full arrangements of records $-Represents the record of current determination $1-Represents the past determination $_1-Represents the following determination Bookmark01- means the Bookmark name

1-level: Raw information is stacked and we make QVD 2-level: QVD is changed over in business login and the prerequisite of business and information display is made. 3-level: Reading all QVD from 2-level and we make a solitary QVW.

Qlikview stores the information in QVD as QVD has information pressure ability. Qlikview has preferred execution over other BI in light of its memory investigation approach.

Parallel Load can be utilized for just a single application implies we can just peruse the information from one QVW application and additionally set contents is likewise a confinement.

Subset Ratio: It is utilized for effortlessly spot issue in key field association.it is significant for key fields since they are available in numerous tables and don’t have a similar esteem. Data Density: It is the field which contain the level of column which contain the non-invalid esteem.

Upgraded stack is a lot quicker and ideal particularly for huge arrangement of information. It is conceivable if n o change are set aside a few minutes of load and no separating is finished.

Keep and joins do similar capacities yet in keep makes the two tables though join just makes the one table. Keep is utilized before the heap or select proclamations.

Engineered key is where at least two tables comprises more than one normal section between them is called as manufactured key.

Steady load is only stacking new or changed records from the database. With the assistance of QVD records we can utilize gradual Load.

Set: it allots the variable without evaluates the articulation. Let: it allots the variable with evaluates the articulation.

Occupant stack is a piece of stacking information in Qlikview application. It is utilized for stacking information in tables which is as of now stacked in Qlikview application.

It very well may be advanced by making the information into qvds. At the point when finish qvw application is changed into qvd than this qvd will be store in the RAM.

Inner Join LOAD Primeid FROM [C:\Users\Qlikview\Desktop\EMP.xlsx] (ooxml, embedded labels, table is Sheet1); STORE FOOD into FOOD.QVD(QVD); // Finally Store QVD

System Tab We have to select QlikView Management Services(QMS) in that repository Tab we need to select Repository Type XML Repository give Database Name AS QVPR and then give Optional Path for creating Data Base. check the migrate data from current repository Option. then Schedule the Backup Settings based on requirement.

Exist() is used commonly in where clause is the values need to load whatever we have already in QVD those records need to load that time we are used Exist() function. Not Exist() these function we are used for Update and delete records updating in QVD. these also we are using where clause.

we have one function to find-out the qvd records no using below Function. QvdNoOfRecords (‘path with filename’)

open the QVD file in a text editor, notepad will do, and you can see which QVW was used to create the file in the tag.

yes we have option to load data within the script using Inline load. Example: edit script —> insert menu —> Load Statement –> Load Inline. here we can generate the data. load * inline [ A,B 1,AA 2,BB 3,CC ];

Using Pivot We can able to see use dimension is Product and Exp is Sales

In QlikView we have two types of Variables they are SET 2.LET. SET: this is static variable these variable we can able to create in edit script only. this only use for constant values, set variables not able to do evaluations. EX: set variable = ‘sathish’; // here it’s shows Sathish. a=10 b=20 set c=a+b // here its display a+b only because set variable not able to do caluculations. LET: this variable is dynamic variable, it’s Possible To evaluate the values like below, and front end also possible to create LET Variables. a=10 b=20 Let C=a+b // here let variable will gives addition of a+b value 10.
