Often the content generated by enterprises on Power BI includes classified and confidential data.

While both the Power BI service and Power BI report server can be accessed through any browser both on desktop or on mobiles, there are mobile-optimized Power BI apps available as well.

There are Power BI apps compatible with Windows, Android, and iOS devices, which enable users to connect to Power BI service as well as Power BI report server on their smartphones and even tablets and iPads.

The packs can be customized with labels that can help users identify the content precisely. People with access to the content pack can use the content from the packs to create new dashboards.

12. Are there any security features available on Power BI?

Power BI uses Row-level Security for its reports and dashboards. Along with the filters, the row-level security restricts access to Power BI reports and other content. In this feature, users can regulate the rules of access and publish the same using Power BI Service.

Row-level security also includes specific functions to monitor the access of current users to appropriate content. However, Row-level security is only available on premium Power BI subscriptions.

13. Describe the Gather function of the Power BI process

The Gather function in Power BI collects and transforms data. As with the case of Query Editor, the data is gathered using the Gather function from multiple sources and stored in a single location. This facilitates smooth and prompt data analysis.

Following the collection, the data is transformed, which necessarily entails the removal of errors and any inconsistency. The end product of this process is clean data, which is aligned with the rest of the data stores in Power BI.

14. What role does the Store Function perform in Power BI?

Once the data is gathered, it is stored in a single location. This store is interchangeably referred to as “data warehouse or data mart.” There is, however, a slight difference between the scope of the two. While a data warehouse accumulates data from any part of the organization, data mart only incorporates data from a particular area or department of the organization.

The Store function saves the data in formats that allow for fast retrieval and analysis. It also aggregates numerous individual data transactions for determining particular outputs. The Store functions help in optimizing the data for online analytical processing (OLAP).

15. Describe the Model Function in Power BI

The Model function increments the role of the Store function. It mainly serves two purposes. It presents the queried data to the users in a visual and comprehensible form without any tables or field names.

Secondly, it securely stores internal formulas to perform business calculations in a single location. This eliminates the need to re-create the calculations every time a need arises. They can simply be pulled out using the model function.

16. What is the use of Visualise function in Power BI?

The Visualize function is responsible for data analysis and data visualization. It helps in creating charts, tables as well as gauges on reports and dashboards. While some visualizations serve specific purposes, others are created for broad-based sharing across Power BI networks.

17. Describe the role of the Share function in Power BI

The share function develops a convenient mechanism for sharing and delivery of the content produced in Power BI among the organization or chosen users. It creates a common location where users can access the content. Needless to say, this location is fortified with proper security measures to enable only authorized access.
