When should I use local storage vs database?

When should you use local storage?

Local storage provides at least 5MB of data storage across all major web browsers, which is a heck of a lot more than the 4KB (maximum size) that you can store in a cookie. This makes local storage particularly useful if you want to cache some application data in the browser for later usage.

Is it better to store files in database or filesystem?

Advantage of the File System over Data base Management System is: When handling small data sets with arbitrary, probably unrelated data, file is more efficient than database. For simple operations, read, write, file operations are faster and simple.

Can you use LocalStorage as a database?

At its core, a browser's Local Storage is similar to a database: it allows us to store, retrieve, remove, and manipulate data, all directly within the browser — no database required. But when it comes down to it, it's really just a big key-value store (much like the PHP arrays with discussed in Lesson 3).

Should I use db to store file?

Performance can be better than doing it in db. To justify this, If you store large files in db then it may slow down the performance because a simple query to retrieve the list of files or filename will also load the file data if you used Select * in your query.
