to get databases.
5. Power BI (.pbi) You can use Power BI Desktop to query and load data from external data sources.
- A report is one or more pages of interactive visuals, text, and graphics that makes up a single report.
- All of the visualizations in a report come from a single dataset.
- A dashboard represents a customized view of some subset of the underlying dataset(s).
- A dashboard is a single canvas that has tiles, graphics, and text.
- Purpose of Dashboards is to
- get all the info at one place, needed to make decisions.
- to monitor the most-important info about your business.
