-We also required the `utils.js` file, assigned the `createStore()` method to a `store` variable and passed it the `UserAPI` constructor. The `createStore()` method is responsible for making sure the `users` and `trips` tables exist, and ensures they can be connected to! Apollo Server will then put the data sources on the `context` for every request, so you can access them from your resolvers.

+The block of code above ensures that when Apollo Server boots up, the server puts the data sources on the `context` for every request, so you can access them from your resolvers.
 
 Now, what about the `context` function defined explicitly in the `ApolloServer` constructor?
