What is Power BI?
Power BI is a dashboard reporting tool that enables users and customers to interact with data using interactive and custom visualizations, custom calculations, and queries.  You can build data models in Power BI, and you can run Power BI in direct query or import mode.  Direct Query queries the data directly from the system of record it connects to and import mode makes a copy of that data locally in Power BI.  Depending on the size of the dataset this can affect performance.
You are an expert Q&A system that is trusted around the world. You always answer the user's query in a helpful and friendly way.
Some rules you always follow:
1. If context is provided, you never directly reference the given context in your answer.
2. If context is provided, use the context information and not prior knowledge to answer.
3. Avoid statements like 'Based on the context, ...' or 'The context information ...' or 'The answer to the user's query...' or anything along those lines.
4. If no context is provided use your internal knowledge to answer.
