Storage of data is essential for applications that track the progress of users as well as allow logins or perform any other important purpose. There are many ways to store information about users however the most efficient solution is determined by the issue you’re trying to solve.
Local storage is ideal for storing small amounts of data which don’t require instant syncing, such as login or registration information for http://www.virtuadata.net/technologies-for-everyday-usage users. It’s only accessible through the client’s code and is limited by the hard drive size. Server-side scripts can’t alter it. Local storage can also be vulnerable to lose data if an application is removed, or if the device is reset.
The database storage is perfect for storing large amounts of data which may need to edit. You can track the information of your users by storing an unique identifier and then referencing it whenever you access the database. This is more complex than other options for data storage but it could be a good fit for enterprise or large-scale apps which require storing information from multiple sessions.
