Hi All, recently I had been struggling to get a free/opensource version of MySQL database for development perspective that can be readily available on public domain. After spending 10-15 mins on search, I found this wonderful website ( https://www.db4free.net/ ) that is made for developers to avail a free MySQL database and that in public domain. Below is the brief introduction of this website and how we can quickly get a MySQL DB instance- db4free.net provides a testing service for the latest - sometimes even development - version of the MySQL Database Server. You can easily create an account for free and test your applications.  db4free.net's MySQL server will be updated very soon after a new version is released, usually on the same day or very soon after. This cannot be used for production.  If you need a MySQL database for production use, please do not use db4free.net!  #Step1: SignUp Process Kindly refer to link https://www.db4free.net/...
