• QlikView Desktop

QlikView Desktop is an integrated development environment used for data extractions and creating transformation models. It’s a Windows-based platform that enables you to perform data analytics, create GUI layouts, visualizations, and export them as reports. 

• QlikView Server

It’s a combination of QlikView web servers and applications that acts as a presentation layer between the end-users and servers. QlikView Server is used to host, manage, and distribute QlikView documents, reports, delimited files, and dashboards with proper data access and security. The server has an in-memory analytics engine and access points that allow it to connect with various data sources and get live feedback. 

• QlikView Publisher

QlikView Publisher is also a server-side application that closely works with QlikView Script and enables the users to perform two main functions:

• • Directly load the data into QVW files from various sources such as SAP Net, Informatica, SQL server, standard files, etc. 
  • Used to create tasks and trigger-based reloads for the QlikView application. 

• QlikView Management Console(QMC)

The management console has a web-based interface that centrally manages all the components of QlikView’s environment. Administrators use it to provide data access for various documents and deploy associative models on the server. 

• QlikView User Access

It’s a front-end component of the QlikView environment and provides various access points in the form of web-browsers. These access points enable the user to fetch the data from QlikView Server, run database queries, and perform other operations from a laptop, desktop, or mobile device. 

QlikView Architecture

The overall architecture of QlikView can be segregated into three main components:
