QlikView Desktop
The QlikView Desktop application is an integrated development environment that may be utilized for the purposes of data extraction as well as the creation of transformation models. It is a platform that runs on Windows that gives you the ability to perform data analyses, construct graphical user interface layouts and visualizations, and export the results as reports.
QlikView Server
It is a conglomeration of QlikView web servers and applications that performs the function of a presentation layer between the end users and the servers. It is possible to host, manage, and distribute QlikView documents, reports, delimited files, and dashboards using QlikView Server, which also ensures that appropriate data access and security measures are taken. The server is equipped with an in-memory analytics engine as well as access points, which enables it to connect with a wide variety of data sources and receive real-time input.
The QlikView Publisher
The QlikView Publisher application is also a server-side application, and it works closely with the QlikView Script application. It gives users the ability to execute two primary functions, which are as follows:
- The data can come from a variety of sources, including SAP Net, Informatica, SQL servers, standard files, and so on. This data can then be loaded directly into the QVW files.
- For use in the QlikView application to build tasks and trigger-based reloads.
- QlikView Management Console (QMC)
- A web-based interface is used by the management console to perform centralized management of all of the components that make up QlikView’s environment. It is utilized by administrators in order to implement associative models on the server and to give data access to a variety of documents.
QlikView Users Access
It is a component of the QlikView environment that serves as the front end and offers a variety of access points in the form of web browsers. Through the usage of these access points, the user is able to retrieve data from QlikView Server, conduct database queries, and carry out a variety of other tasks using a mobile device, laptop, or desktop computer.
The Architecture of QlikView
The overall structure of QlikView may be broken down into its three primary components, which are as follows:
Front End
The element of the QlikView architecture known as the front end includes all of the applications, web-based programs, and software components that are used to interact with the data and Qlikview documents. The user is able to view QlikView reports and connect live data sources through the use of a straightforward drag-and-drop operation thanks to the front end layer.
Back End
Back-end components include the QlikView developer and the QlikView Publisher. This part of the application is sometimes referred to as the application platform. It is a repository for the QlikView documents and other files, which may be saved in a number of different file formats. The application platform is the one that is responsible for receiving requests to access or connect with various data sources. QlikView Publisher is the tool that is used to distribute the data.
Data Source End
The data access layer that is utilized in the execution of the ETL can be found at the data source end (Extraction, Transformation, and Loading of the data). It is the most essential layer, and it is responsible for retrieving data from a wide variety of data sources, such as SAP, Excel spreadsheets, Oracle, and so on.
