explanation for non-techies**

Imagine you have a library with thousands of books, each containing sensitive information. You want to ensure that only certain people can access specific books based on their roles and the confidentiality of the information. Microsoft Purview acts like a librarian who assigns sensitivity labels to each book, indicating how sensitive the information is and who is allowed to read it.

Now, Azure AI Search is like a smart search assistant in this library. It can find books based on the topics you are interested in, but it also respects the librarian's labels. This means that if a book is labeled as sensitive, the search assistant will only show it to people who have the right permissions. This helps prevent anyone from accidentally accessing or sharing information they shouldn't.

The search assistant works with various sections of the library, such as SharePoint, OneLake, Azure Blob, and ADLS Gen2, ensuring that no matter where the book is located, the same rules apply. This way, the organization can maintain control over its information, ensuring it is shared only with those who are authorized, much like how a library maintains control over who can check out certain books.

By integrating Microsoft Purview with Azure AI Search, organizations can confidently search through their data, knowing that their information protection policies are being enforced. This helps prevent data oversharing and ensures compliance with data protection standards, much like a library ensures that only the right people can access certain books.
