Question: In a Service Enabler Architecture Layer for Verticals (SEAL) setup, what type of databases may be associated with VAL services at the application plane, according to their specific use cases?
Option 1: Only Generic User Database, applicable across all VAL services
Option 2: Databases specific to each VAL service provider, not tied to particular service types
Option 3: Service-specific databases (e.g., MCPTT, MCVideo, MCData user databases) tailored to the needs of each VAL service
Option 4: No databases are associated with VAL services at the application plane; they rely on external storage
Explanation: In a SEAL setup, different VAL services have distinct requirements. Each may have a corresponding, specialized user database to efficiently manage service-specific user profiles and information, allowing for tailored support and optimized performance for each service type at the application plane.
