Power BI Semantic Model and Different Connection Modes

What is Power BI Semantic Model?

The Power BI semantic model, which was earlier called the Power BI shared dataset, is a way to organize data in a structured format. It defines tables, connections between them, calculations, and business rules for creating reports and analyzing data. It serves as a single, central layer for data, making it easier for everyone in an organization to access data in a consistent, fast, and secure way. This helps teams use self-service tools to analyze data and make decisions.

Here are some common use cases for creating Power BI semantic models:

1. Centralized Data Governance: Ensures consistent definitions, relationships, and business logic across reports, promoting data accuracy and consistency across the organization.
2. Simplified Self-Service BI: Offers a simple and clear way for business users to make reports and dashboards without needing technical skills, helping everyone use data on their own.
3. Data Security with Row-Level Security (RLS): Lets you control who can see what data by setting up security roles, so users only see the information they are allowed to access.
4. Performance Optimization: Makes reports run quicker by organizing data better, improving connections between data, and summarizing data in advance, which helps when working with big amounts of information.
