Here, during this introduction to Qlik Sense blog, we are getting to discuss the essential concepts of Qlik Sense –
i. Associative selections
Usually, making selections may be a trusted way of checking out data and relations in data. In Qlik Sense a bit like QlikView, you’ll make selections on field values and by the virtue of associative model, every data value associated with the choice you only made will filter and display a subset of knowledge with just the info values relevant to the chosen value. the choice you create can call as an input and therefore the resultant data set or the response that indicates by the colours call because the output.
Basically, the output may be a colored representation with different value cells indicated in several colors features a certain method or depiction. we will understand this by learning the precise color that assigns for every selection state.
• Green (with a tick mark) indicates Selected.
• White is for the choice state Possible.
• Light Gray represents Alternative.
• Dark Gray is represents Excluded.
• Dark Gray (with a tick mark) shows the chosen Excluded state.

ii. Applications
An application is sort of a Qlik Sense file which you create to perform the certain analysis. So, you’ll create any number of applications in Qlik Sense. An app is an entity which contains data as dimensions, measures, visualizations, sheets, sheet objects stories etc. the info structure keeps intact in an application and you’ll use it any number of times you would like for viewing, modifications, sharing etc. The extension during which we save these files or apps is ‘.qvf ’. Logically and structurally, we will divide a Qlik Sense app into two parts, a Foundation, and a Structure and Visualization part. the inspiration consists of all the components that structure the very base or foundation of the app’s structure, whereas the weather like bookmarks, visualizations, stories, snapshots are a neighborhood of the structure and visualization.

iii. Sheets
The sheets in Qlik Sense apps are like individual pages of a book. There are often n number of sheets in an application. So, the sheet acts as a container of all the visualizations and sheet objects that represent data. The sheets don’t cut the associations or links between data tables, the associations reflect altogether the tables no matter which sheet they lie on.

iv. Visualizations
Once you load data into Qlik Sense, there’s an inventory of options during which you’ll visualize your data. Choices of visualizations range from chart types, tables, maps, texts, images, KPIs, etc. you’ve got simple drag and drop the visualization of your option to the editing pane and begin modifying it as per your requirement. Each sheet object or visualization has its own exploration menu from where you’ll dynamically modify the respective visualization in several ways.

v. Dimension
Dimensions are those fields during a data table which are composed of descriptive or informative text values. you can’t perform mathematical operations on the dimension values. which is why usually the x-axis of the bar charts and therefore the slices of the chart are dimensions. As you’ll see within the image below which may be a bar graph , the values of the filed ‘Product type’ are dimensions.

Introduction to Qlik Sense – Dimension
vi. Measures
As the counterpart of dimensions, measures are those data fields which contain numeric or such values which are calculable. We perform Mathematical operations on measure values. Basically, we usually plot Measures on the y-axis of a graph or chart. All the measures are utilized in some kind expressions. These expressions contain any of the aggregation functions available like Sum, Min, Max, Avrg, Count etc.

vii. Data searching
We can search all the info residing within the bounds of your Qlik Sense application with the info search tool. it’s located at the highest left of the Qlik Sense app. Also, the search tool powered by Qlik Sense’s associative engine. you’ll perform differing types of text searches within the search bar.

viii. Navigation
The navigation option, at the highest left of the app window, consists of some important options that relate to app and data management. you’ll overview the whole app and therefore the situation of the components in it. Also, to look at and manage data, you’ve got the choices like Data manager, Data load editor, Data model viewer.

Introduction to Qlik Sense – Navigation
ix. Data Model and Data model viewer
Every Qlik Sense application, having data organized in tables will naturally create a knowledge model for that application. a knowledge model visually represents the structure of knowledge residing within the application you made. The optimal data model is taken into account as a normalized start schema or snowflake schema. These schemas must not have any circular references because it distorts the info structure and disrupts the graceful functioning of the tool. Hence, to form your data model optimum, you would like to form sure that there’s a central fact table having keys to the size liking with other tables and connected to the present central tables through unique keys are individual tables having key dimension and measure fields. to look at the info model of your application, you’ll attend the Navigation icon and choose Data model viewer from there.
x. Data load script
Data are often loaded from external sources and therefore the existing data are often modified and manipulated within the Data load script which you’ll access by getting to Navigation icon within the toolbar then selecting Data load editor. The common fields form discrete data tables are recognized by the software’s logic and associations are created thereof. you’ll manipulate the info in some ways through scripting by using keywords, functions, variables, and expression hence, creating a code.

xi. Bookmarks
Bookmarks are made to save lots of the add the state during which it’s presently in. Similarly, in Qlik Sense, you’ll create bookmarks from the bookmark icon given at the toolbar to save lots of the present state of selections made. you’ll open and add the bookmarked sheet anytime you would like .

Introduction to Qlik Sense – Bookmarks
xii. Snapshots
A screenshot or snapshot as called in Qlik Sense are often taken of any visualization created during a Qlik Sense app. The state of a knowledge object captures forever within the snapshot and doesn’t change with any changes that we make within the original data object. Snapshots are taken for using it in Qlik Sense stories. and each visualization that you simply create is present an icon which is employed to require a snapshot of that visualization and is saved as a picture .
xiii. Story
Data storytelling may be a unique feature of Qlik Sense. Using this, you’ll summarize your data analysis and tell it as a story to share insights and opinions on data you analyzed. A story has several slides which have images (snapshots), descriptive texts and shapes used for pointing and emphasizing on important data points. So, you’ll create a story from the icon given at the toolbar.

Introduction to Qlik Sense – Story
xiv. Streams and Publishing
All the applications made by the user resides during a centralizes Qlik Sense Hub. Logically, these applications are a neighborhood of a stream, which suggests that only a selected group of users will have access to the applications of a specific stream. Suppose you’re authorized to access only the apps from stream 1 and that we are authorized to access the apps from stream 2. We cannot gain access to every other’s streams.

Also, each user has an access type for the apps in their stream. the 2 sorts of access are Publish and skim . Publish is that the right for publishing your own apps into the stream which can’t be edited by the other user but you. So, the Read type access lets the users, including you, only view and analyze the info and not manipulate the prevailing apps or publish new ones. you’ll have either of the 2 access types or both of them.

Introduction to Qlik Sense – Stream
The two images show how the concept of stream works. within the first image, the stream type is Everyone, which suggests that everybody can access the apps in it and therefore the second image shows a narrower stream during which only the users from finance department can access apps relevant to them. If you’ve got the proper, you’ll publish apps into specific streams and may also update new stories or sheets into existing apps. The apps are published within the respective streams from the Qlik Sense Management Console (QMC).
xv. Authorization and Access
Qlik Sense supervisor manages Authorization and access. This decides the user’s access, modification, and publishing rights. By default, the settings are that only the one who created an unpublished app can see and modify it, an app can’t be modified once after publishing and only the users to whom access to a particular stream has been granted can have access to the apps within that stream.
