The document contains SQL commands that define the schema for a wellness application database. It includes tables for users, interests, steps, themes, and relationships between them such as which users are following other users and which interests and themes are associated with different steps. Sample data is inserted into the tables to establish an initial set of 20 users along with their interests, the steps they have taken, and the relationships between them.

Task 2: Elasticity
1. Consider the following two products: an ‘overseas trip’ and

Frustrated local businesses who took part in the survey said
travel times for
each of their work vehicles had jumped, on average, by 59
