Understanding Supabase Dashboard Components

Which component in the Supabase dashboard allows you to view and manage your database tables visually?

A SQL Editor

B Table Editor

C Authentication Settings

D API Documentation

Designing a Supabase Table for User Activity Tracking

You need to design a table in Supabase to track user activity events with timestamps and event types. Which table schema best supports efficient querying for daily active users?

A A table with columns: user_id (UUID), event_type (text), event_timestamp (timestamp), indexed on user_id and event_timestamp

B A table with columns: user_id (UUID), event_type (text), event_date (date), no indexes

C A table with columns: user_name (text), event_type (text), event_timestamp (timestamp), indexed on event_type

D A table with columns: user_id (UUID), event_type (text), event_timestamp (timestamp), indexed only on event_type

💡 Hint

Consider which columns are needed for filtering and how indexes improve query speed.

Indexing user_id and event_timestamp allows fast queries for daily active users by filtering on user and date ranges.
