Common Data Service
Common Data Service (CDS) is a cloud-based data storage and modeling platform developed by Microsoft, primarily used within the Power Platform and Dynamics 365 ecosystems. It provides a standardized way to store and manage business data with built-in security, business logic, and integration capabilities. CDS enables developers to create custom entities, relationships, and workflows to support applications without managing underlying infrastructure.
Developers should learn CDS when building business applications on Microsoft's Power Platform or Dynamics 365, as it offers a unified data layer with pre-built connectors and low-code/no-code tools. It is particularly useful for scenarios requiring rapid application development, such as CRM systems, workflow automation, and data-driven dashboards, where data consistency and security are critical. CDS simplifies integration with other Microsoft services like Azure, Office 365, and Power BI.
