MySQL is an open source, relational database management system (RDBMS) based on structured query language (SQL). MySQL is available on all major operating systems, including Windows, Linux and Solaris. It is free to use for individuals and non-production environments under the GNU General Public License; however, if used commercially, a commercial licence is required.
MySQL, like other relational databases, stores data in tables, columns and rows. Each entry is defined by a unique identifier. Its raison d'être has always been the performance and reliability of the database. MySQL was designed and optimized for the web development arena; it is arguably the most common database used in web server deployments. MySQL works very well with Apache and PHP and is often the go to database for LAMP stack deployments. SQLOS also handles lower-level functions to avoid conflicting updates.

The Microsoft .NET Framework is a software component that can be added to or is included with the Microsoft Windows operating system. It provides a large body of pre-coded solutions to common program requirements, and manages the execution of programs written specifically for the framework. The .NET Framework is a key Microsoft offering, and is intended to be used by most new applications created for the Windows platform.
Programs written for the .NET Framework execute in a software environment that manages the program's runtime requirements. This runtime environment, which is also a part of the .NET Framework, is known as the Common Language Runtime (CLR). The CLR provides the appearance of an application virtual machine, so that programmers need not consider the capabilities of the specific CPU that will execute the program.
