Qlik Sense Essentials – Understanding Key Concepts
Qlik Sense is a business intelligence and data visualization platform that is used to explore and analyze data, create interactive dashboards and reports, and share insights with others.
Qlik Sense is a Business Intelligence (BI) platform that uses a unique associative data model and a user-friendly interface to enable users to create and share interactive visualizations and analyses. Here are some key concepts to understand when working with Qlik Sense:
Here are some key concepts to understand when working with Qlik Sense:
- Data model: The data model in Qlik Sense refers to the structure and organization of the data that is used in the application. It includes the tables, fields, and relationships that define how the data is organized and connected.
- Visualization: Visualizations are graphical representations of data that are used to display and analyze data in Qlik Sense. There are a variety of visualization types available, including bar charts, pie charts, line graphs, and scatter plots, which can be used to display different types of data.
- Dashboard: A dashboard is a collection of visualizations and other elements that are used to present data in a cohesive and interactive manner. Dashboards can be used to display data from multiple sources and can be customized to meet the specific needs of an organization.
- Story: A story is a series of dashboards that are used to present data in a narrative format. Stories allow users to explore data and insights in a step-by-step manner and can be used to present data to a wider audience.
- Extension: An extension is a custom visualization or other component that can be added to a Qlik Sense application. Extensions can be developed using the Qlik Sense Extension API and can be used to enhance the functionality and capabilities of a Qlik Sense application.
- Data model: Qlik Sense uses an associative data model, which allows users to easily navigate and explore data relationships. This model allows users to make connections between different data sources and see the relationships between the data without the need for complex joins or queries.
- App: An app is a container for one or more visualizations and analyses that are created and shared in Qlik Sense. Each app is made up of one or more sheets, which contain visualizations and other elements that users can interact with.
- Associations: Associations are the connections between different data sources in a Qlik Sense app. These connections allow users to easily explore and understand the relationships between different data elements.
- Script: A script is a set of instructions that is used to load data into a Qlik Sense app. The script can be used to load data from various data sources, such as databases and files, and can be used to transform and clean the data before it is loaded into the app.
- Master items: Master items are reusable elements that can be used across multiple sheets and apps. These elements can include visualizations, dimensions, and measures.
- Expressions: Expressions are used to create calculations and aggregations in Qlik Sense. They can be used to create calculated fields, define the data in a visualization, and more.
