  • No need of any dedicated servers to store database everything gets stored in the hard disk,
  • Very Portable due to file-based system,
  • Highly compatible with nearly all programming languages

Most Useful for: SQLiten is best suited for small-scale testing and development purposes which don’t require so many features.

4. MongoDB

In this Cloud era, MongoDB is a general-purpose, document-based, distributed database built for modern application and Used by millions of developers for the world’s most innovative products and services. MongoDB stores data in JSON-like documents which is much more expressive and powerful than the traditional row-column model.

It can be used for a wide variety of applications, from banking to websites with much-improved query optimizer and cutting edge features. There are dynamic columns in a table and the latest version supports JSON and GIS. 

  • Additional functionality than MySQL,
  • Provides best data processing facilities,
  • Cross-platformed supports numerous programming languages,
  • Provides the Galera cluster technology,
  • Quicker and more transparent security releases.
