Features of Qlik Sense
Qlik Sense has a lot of features that make it stand out. Let’s take a look at them:
Qlik Sense uses an associative model to process data. All of the data is put into Qlik Sense, which is then linked or associated with each other. When a data value or field has any association with another data value or field, it can be seen clearly. This helps users generate unique insights. These associations can be easily viewed using a smart search.
Smart Visualizations and Analytics
Qlik Sense has smart visualizations that are highly interactive. The graphics quickly adapt as the resolution of the screen changes. Qlik GeoAnalytics is a feature in Qlik Sense that makes use of smart visualizations and analytics by creating mapped visualizations.
Self-Service Creation has made making apps really easy in Qlik Sense. Qlik Sense has an easy drag-and-drop feature that users can use to make apps easily, without having to deal with queries and scripts.
Centralized Sharing and Requirement
Qlik Sense lets users share reports and applications through a centralized hub. Users from a company can also form teams and collaborate with other companies.
Data Storytelling and Reporting
Qlik Sense is widely known for its storytelling capabilities. Qlik Sense successfully generates a smart story and gives useful insights to the data analyst. This helps the user in generating unique insights from the data.
Qlik Sense supports mobile devices. It makes it easy for the users to work on the move.
Custom Applications, Embedded Analytics, and Extensions
Qlik Sense offers an API where users can develop custom applications. Users have an option of adding extensions for analysis while they can also add various plug-ins into the Qlik Sense app. You can also embed Qlik Sense analytics into other apps.
Data Preparation and Integration
Once the data is loaded into Qlik Sense, it is cleaned, transformed, integrated, and associated with other data sets available. Data integration is facilitated by the drag-and-drop feature. There are products like Qlik Connectors and Qlik DataMarket which support data integration and preparation. They help connect data from other sources.
Enterprise Governance and Scalability
Enterprise-class management services are provided with QlikSense. These services give assured data security to the enterprise. The Qlik Management Console (QMC) is responsible for centralized data monitoring and management. Qlik Sense also allows elastic scaling which helps users load and analyze huge volumes of data.
The QIX Engine
The QIX Engine powers all the features of Qlik Sense that we’ve talked about so far. The Qlik Indexing Engine (QIX Engine) is responsible for indexing and compressing data for Qlik Sense. This helps fetch more and more data from various sources.
Key Capabilities of Qlik Sense
Some of the key capabilities of Qlik Sense are as follows:
- Self-service capabilities
- Associate model
- Smart visualization and analytics
- Centralized sharing and collaboration
- Data storytelling and reporting
- Allows mobility
- Data preparation and integration
- Allows enterprise governance and scalability
- Insight Advisor by Qlik (AI-supported)
Qlik Sense Architecture
Qlik Sense architecture consists of several components and services that work in conjunction with each other in order to bring out the data management and analytics capabilities of Qlik Sense architecture. Qlik Sense architecture is easily scalable and flexible, comprising one or more nodes within a site. Based on the latest Qlik Sense technology, this BI tool has enterprise-ready deployment capabilities.
To completely understand the architecture of Qlik Sense, you will first need to unveil the underlying components of Qlik Sense architecture and its services. In this Qlik Sense tutorial for beginners, we discuss the components of Qlik Sense architecture one by one.

Qlik Sense Architecture Components
This segment of the Qlik Sense tutorial discusses the four components of Qlik Sense and their functionalities:
Qlik Sense Clients
Qlik Sense is an easy-to-use platform, the credit of which goes to its user-friendly design. With the help of its easy drag-and-drop functionality, users can seamlessly create a designed dashboard for business analysis. Users can perform operations on the data and create applications with a range of visualizations that are available on Qlik Sense.
Qlik Management Console (QMC) lets the administrator centrally manage all the operations that are taking place in Qlik Sense. Now, let us briefly talk about the services managed by QMC:
- Data connectivity
- Application management
- Task management
- Security administration
- Data monitoring
Qlik Sense Nodes
Qlik Sense nodes are physical or logical computers that deploy separate or a combination of services. Generally, a node has three types of roles based on the services it provides. They are:
- User or consumer node that delivers apps to the end-users
- Scheduler node that manages all the service and app reloads.
- A proxy node that handles authentication processes, load balancing, and session handling.
All nodes in Qlik Sense work independently and can be used for production, development, or both at the same time.
Qlik Sense Sites
Qlik Sense site consists of a node system. It can have single or multiple nodes, also known as servers. Every node has a single repository, database, and license. A single-node deployment consists only of a central node that has all the required services deployed on it.
While single nodes work in sync with data repository and file-sharing systems, a multinode site is a distributed system having services distributed across many nodes. On the other hand, the central node manages all the peripheral nodes that share the repository, database, and license key. A multinode system also provides better scalability, resilience, reliability, governance, capacity, and flexibility to suit customer requirements.
Qlik Sense Storage
The two storage components of Qlik Sense are the repository database and the file-sharing system. While repository data, also called Postgre database, keeps metadata, a file-sharing system stores the Qlik Sense application data such as dimensions, measures, objects, and visualizations. These details are stored as binary files and such data files are made available to all nodes or servers on a site.
Qlik Sense Architecture Services
To learn Qlik Sense in a more comprehensive manner, we will have to learn about the following Qlik Sense services:
Qlik Sense Proxy (QSP)
This is the entry point in Qlik Sense for users and administrators through different sources such as the hub and management console. QSP mainly serves four purposes, license management, session management, load balancing, and linking with user identity providers such as active directory, SAML, etc.
Qlik Sense Engine (QSE)
This is the main engine that facilitates the major features and functionalities of Qlik Sense. Some of the functions of QSE include data indexing and calculations for in-memory data, smart searching, interactive and self-service interactions, and corresponding with Scheduler, repository, and applications.
Qlik Sense Schedule (QSS)
As the name suggests, the function of this service is to schedule and coordinate data loads and application reloading.
Qlik Sense Repository (QSR)
It refers to the place for all data and information related to the configuration and management of other Qlik Sense services. The primary role of QSR is to manage user definitions and security.
Qlik Sense Applications (.QVF)
This is the last layer for users; it is used for creating visualizations and sheets.QVF files also have compressed data that is loaded into the Qlik Sense in-memory and final presentation layer.
