Data Science Model Deployments and Cloud Computing on GCP - Database

The video tutorial explains the concept of databases and their role in data persistence for web applications. It uses a To Do app to demonstrate how data is not persistent until it is saved to a database. The tutorial introduces Postaco, a tool for visualizing data in Postgres databases, and shows how data persists across client and server sessions. Finally, it recaps the full stack components: front end, client, server, and database, highlighting their roles in web applications.

What is the primary role of a database in a web application?

• To enhance the speed of the application

• To persist data even when the application is closed

• To temporarily store data in the browser

• To manage user authentication

In the To Do app example, when does the data become persistent?

• When the 'create' button is clicked

• When the task is entered

• When the page is refreshed

• When the application is closed

What tool is used to visualize the data stored in the database in the video?

• MySQL Workbench

• MongoDB Compass

• SQLite Browser

• Postaco

What happens to the data in the database when the client and server are both shut down?

• The data is lost

• The data is temporarily unavailable

• The data remains intact

• The data is duplicated

Which of the following is NOT a component of the full stack as mentioned in the video?

• Operating System

• Database

• Client

• Front end
