How does data persistence work in web applications?

Data persistence in web apps refers to the ability to store data in a way that it remains available even after the application is closed or refreshed. This is typically achieved using databases, local storage, or session storage.

What are the different methods for achieving data persistence?

Common methods include using relational databases like MySQL, NoSQL databases like MongoDB, and client-side storage options like localStorage and IndexedDB.

Can you explain the difference between local storage and session storage?

Sure! Local storage allows data to persist even after the browser is closed, while session storage only keeps data for the duration of the page session.

What are some best practices for managing data persistence?

Best practices include using appropriate storage methods based on data sensitivity, regularly backing up data, and ensuring data is encrypted when necessary.
