MYSQL MySQL is a fast, easy-to-use RDBMS being used for

many small and big businesses. MySQL is developed, marketed, and supported by MySQL AB, which is a Swedish company. MySQL is becoming so popular because of many good reasons:

MySQL is released under an open-source license. So you have nothing to pay to use it.

MySQL is a very powerful program in its own right. It handles a large subset of the functionality of the most expensive and powerful database packages.

MySQL uses a standard form of the well-known SQL data language.

MySQL works on many operating systems and with many languages including PHP, PERL, C, C++, JAVA, etc.

MY SQL CONTINUED…MySQL works very quickly and works well even with large

data sets.MySQL is very friendly to PHP, the most appreciated

language for web development.MySQL supports large databases, up to 50 million rows or

more in a table. The default file size limit for a table is 4GB, but you can increase this (if your operating system can handle it) to a theoretical limit of 8 million terabytes (TB).

MySQL is customizable. The open-source GPL license allows programmers to modify the MySQL software to fit their own specific environments.

301 REDIRECTIONThe HTTP response status code 301 Moved Permanently is

used for permanent URL redirection, meaning current links or records using the URL that the response is received for should be updated. The new URL should be provided in the Location field included with the response. The 301 redirect is considered a best practice for upgrading users from HTTP to HTTPS. RFC 2616 states that:

If a client has link-editing capabilities, it should update all references to the Request URL.

The response is cacheable.Unless the request method was HEAD, the entity should

contain a small hypertext note with a hyperlink to the new URL(s).

If the 301 status code is received in response to a request of any type other than GET or HEAD, the client must ask the user before redirecting.
