The image depicts the FEMA Dex Data Lake High Level Architecture, which illustrates a comprehensive data management system designed to support multiple analytical and operational functions. The architecture consists of three primary layers:

1. Base Layer: Supports ingestion of diverse data types including structured, semi-structured, and unstructured data (represented by database, image, video, audio, and document icons), which feed into the Data Lake.

2. Metadata and Governance Layer: Provides centralized management and control of data assets, ensuring proper data handling and compliance.

3. Data Lakehouse Layer: Enables advanced data utilization through four key capabilities:

• Business Intelligence (BI)
• Reporting
• Data Science
• Machine Learning

This architectural design allows FEMA to consolidate, manage, and leverage various data sources efficiently, supporting the agency's goal of modernizing its technological infrastructure to improve disaster response and individual assistance services.
