Explanation:
Box 1: Microsoft Purview Data Map
For the searchable data catalog, use:
Provide a single searchable catalog of the data in all the databases. The catalog must contain metadata of the data. The solution must minimize storage requirements.
The Microsoft Purview Data Map provides the foundation for data discovery and data governance. It captures metadata about data present in analytics, software-as-a-service (SaaS), and operational systems in hybrid, on-premises, and multicloud environments.
Box 2: Azure Synapse Analytics
Provide a central data lake that contains specific data from multiple databases. The solution must include a big data engine that can create machine learning models.
