Various methods for storing web data Offline

Is there a way to create a client-side database that can automatically sync with a server-side database whenever changes are made to the data?

I am in the process of developing a JavaScript program to manage student application forms. However, the internet connection may be unreliable since the user will be moving around campus with their tablet to collect form data.

Although I have considered using local storage, it lacks database features that I require for this project.

I am seeking technologies that support local database management and offer easy asynchronous syncing capabilities (similar to what Dropbox has done, but as a web application).

I hope my query is understandable. Thank you.

Answer №1

When considering what type of assistance you require, the answer may vary.

To explore further, visit where information on the Web SQL Database specification and IndexedDB is provided.

It is possible that Web SQL Database could be effective, especially in a controlled environment.

Answer №2

Here are various methods of storing data when available:

  • Standard HTTP Cookies
  • Local Shared Objects (Flash Cookies)
  • Silverlight Isolated Storage
  • Storing data in RGB values of automatically generated PNGs that are force-cached using the HTML5 Canvas tag to retrieve pixels (data) later
  • Storing data in HTTP ETags
  • Storing data in Web cache
  • Internet Explorer userData storage
  • HTML5 Session Storage
  • HTML5 Local Storage
  • HTML5 Global Storage
  • HTML5 Database Storage via SQLite

This information is inspired by the concept of evercookies. Some items have been excluded due to short lifespan and lack of space. It's important to avoid directly copying code, especially considering potential limitations with certain libraries like jQuery.
