Microsoft Dataverse is a cloud-based data storage and management service provided by Microsoft. It is designed to provide a secure and scalable platform for storing and managing data used in various Microsoft applications and services such as Power Apps, Power Automate (formerly Microsoft Flow), and Power BI.

Dataverse allows users to create, store, and manage data entities, which are essentially tables that contain structured data. It provides a set of tools and capabilities for creating, defining relationships between tables, enforcing data validation rules, and performing data integration and transformation tasks.

The term "Dataverse" originated from Microsoft's previous data storage and management service called "Common Data Service (CDS)." In 2020, Microsoft rebranded CDS as "Microsoft Dataverse" to align the name with the broader vision of providing a unified and consistent data platform across various Microsoft products and services.

The rebranding was part of Microsoft's strategy to emphasize the central role of data in its Power Platform, which includes Power Apps, Power Automate, and Power BI. The term "Dataverse" reflects the idea of a digital universe of data, where users can store, access, and manage their data assets effectively.
