| The scenarios we've covered above are focused on reading in data to an application and performing queries with user-inputs. If you need to *write* data to the database, this introduces additional considerations we'll cover in a separate article on persistant storage in Shiny apps. | ||

I'm thinking the articles that come out of this can go in their own section (in between Reactivity and Syntax Modes)

| ## Eager loading {#eager} | ||
|
|
||
| Loading all your data into memory when your app first starts is the simplest way to work with data in Shiny. | ||
| This makes it easy create UI from data, and more generally reason about your app's data logic. However, this also means that before a user can interact with your app, the data must be loaded into memory, so be mindful to keep this step as fast and efficient as possible (or consider [lazy](#lazy) loading). |

Might change to "finish being loaded" because we block UI interaction until after the loading step is completed, yes?
