MySQL site database: what it is, advantages over other DBMS

MySQL site database is a system for storing and processing information. A set of interconnected tables, for access to which the MySQL database management system (DBMS) is used. In essence, MySQL is a special open source program that is used on the SQL server. This program is not able to process a large amount of information, but it is ideal for small and large web resources.

Why do you need a database?

Imagine you are driving your site. If you have a small static project that contains only a few html pages, then you do not need to use a database (DB) at all. But these are rare cases when projects created by webmasters remain practically unfilled. As a rule, sites continue to be filled with content, they become more loaded. Such projects are already dynamic, and without a database they are very difficult to maintain.

Keeping gigabytes of information distributed over hundreds of files, you have to spend a lot of time issuing the necessary lines in the operation of the server. To avoid this, we need a database that is engaged in grouping and organizing information. The code for the database is much simpler than the code intended for the use of files. In this case, the request is processed much faster.

In the database, all data is represented by a table with comments, information about objects, etc. It should be noted that the database is constantly changing, complemented by new data, correcting the information that is already in it. And in order to avoid difficulties in the process of administering, adding and changing information, special database management systems were invented. We are talking about one of them in this article, since MySQL is in the highest demand in its field.

What are the benefits of MySQL?

One of the main advantages of MySQL, thanks to which the program is popular with many webmasters, is the high speed of information processing and the functionality of the DBMS. As we mentioned above, this system is open source software, and it is available to any user absolutely free of charge, which also tilts the scale in the direction of MySQL. Most modern hosting companies use MySQL.

The webmaster is able to improve the code and make its own changes to it, which makes the program flexible. MySQL is just one of many softwares that work with SQL.

SQL is a query language designed to organize the management of relational databases (with related data). It is multifunctional and with its help you can adjust, create and remove data from tables, request information from them, create tables themselves, etc.

On a note! In the Internet space, MySQL is also known as “muscle.” This name came up with her webmaster. For example, when they say the phrase “CMS on a muscle”, this means that the content management system of the site (engine) uses the MySQL DBMS.

How is information stored in relational databases?

How is information stored in relational databases?


To understand how relational databases contain various data, it is best to cite as an example a regular table with columns and rows containing names, as well as corresponding phone numbers, addresses, and other information. The relational database also has this type. Each column contains a specific name, and all the values ​​they contain are of the same type. Columns are strictly ordered, unlike rows, which may contain values ​​from different tables. Having made a query to the database, you will be given the result in the table.

All values ​​in the database are divided into two types:

  • Unique.
  • Non-unique.

The first type includes hosting agreements, bank card numbers, etc. Information that can be repeated, for example, name, date of birth, time, etc., is attributed to non-unique ones. The unique data is contained in the list called “unique index”.

Differences of MySQL from other DBMS

It differs from other MySQL programs in that it works without problems with the API interface. With the help of this software, the user easily gets access from the user program to the database management system, even if it is written in C, Perl and other programming languages.

For administering websites, the most commonly used combination is MySQL with PHP. A large number of engines (CMS) are written precisely on the basis of this “bundle”. One of these engines is known to any novice webmaster – a content management system for blogs and WordPress sites, which has gained immense popularity all over the world. In WordPress there is a huge number of functions on the basis of which interaction with MySQL is provided, for example, “mysql_connect”.

Conclusion

In addition to MySQL, today on the Internet you can find a huge number of other database management systems, such as PostgreSQL, mSQL, etc. All of them have a number of advantages and disadvantages, but it is the MySQL program that is the most versatile, convenient and flexible among all the others.
