The How To Of Mysql Databases

MySQL is an open source database, that allows you to build multithreaded columns and tables within the your own database.

Databases are used everywhere and everyday. They allow us to organize and store information needed on whatever basis it is needed for. As technology has evolved databases have grown immensely, and so has the cost. The open source environment has created a solution to the high cost and constantly outdated software that has grown out of control. MySQL is one of the most used open source databases in the world.

In 1996 TeX, a consulting firm in Sweden developed MySQL. The reason for creating this new database was they needed a relational database that could handle a large amount of data and not cost a lot, as well as being fast and flexible. Not finding this anywhere they decided it was time to figure out an alternative; therefore, creating their database from the general idea of mSQL. These days, MySQL is the largest growing relational database out on the market. This open source database can outperform almost all the leading databases in every area. MySQL appears to be growing in the public eye, but before 1999 Linux and Open Source movement were not very well known to the world. MySQL mainly runs on UNIX-based environments, yet there are types for almost every platform out there. Since there has been such a huge growth in Linux, MySQL has become very popular among the Information Technology world. The hard part about this is there is not a lot of documentation available, and if there is it takes a while to find and understand.

MySQL does more then act as a database, but it does manage databases. Through MySQL you can control who uses the databases and how they are manipulated. The general public sees databases like Microsoft Access when they think of databases, but that is not a management system. MySQL allows users to connect to a specific database on the server and issue requests. There are other databases like Access, that you would think are similar to this but there is no interface that controls the connection or answers request. The uses for MySQL are so many; they can range from help desk systems all the way to Web site applications. If you know MySQL you can find away to help yourself in almost any situation, the most practical is in a large system that interacts with another to accomplish a common goal.



There are many benefits of MySQL being used in an Enterprise environment. One major plus is more than one person can be accessing business information at a time. This is critical in huge companies that have a large database that is the functionality of the company. Not only can a large group of people access the information but also there can be several connections at one time. Also the flexibility of MySQL makes it wonderful at the enterprise level. This is a very easy and a very flexible system to use. This system can run on virtually on any platform. MySQL also comes with a source code. Inside the system any deep changes that need to be made can be made easily by the user. If there are missing features inside you can add them yourself. Next MySQL is used at the enterprise level because of its security. When information is confidential you do not want to have to wonder if anyone else could be accessing the information. The security found here is unparallel. The access to the MySQL database can all be controlled by a remote machine that can completely control what a user can view. The system can be locked down even more through the operating system. There are not a lot of other databases that can even compare in the security area of MySQL.

Inside MySQL is mainly a relational database. This kind of a database is made up of columns and tables that can relate to one another. The key value of these relationships is based on the value in the column. This idea was developed by E.F. Codd in the 1970s. He proposed that databases should consist of data that is stored in columns and tables that can relate to each other. His thinking was original compared to the general ideas at the time. His ideas revolutionized the way the databases were created and used. Most of the database today are relational, made this way to accomplish their tasks. MySQL is no different, it truly conforms to the relational database model. This also adds to the ease of using MySQL.

Within MySQL there are many features that make this database management system out perform others. The stability of MySQL has proven itself over the last ten years. One of the first features of the database is that it is multithreaded allowing multiple connections at the same time without slowing down the system. A second feature of MySQL is that there is an online help system. All of the commands are given at a command prompt. To view the help you simply type -help or -?, and this will display a group of information about commands. Third MySQL meets the ANSI SQL92 regulations. ANSI SQL92 was a set of standards that was agreed upon by the American National Standards Institute, and followed very carefully by TeX. Forth you can use MySQL with many different application-programming interfaces. These range from Perl to C/C++ to Java. Fifth the feature that makes MySQL so very popular is it is so very cheap. To have an unlicensed version of it, the cost is nothing. Yet is you wish to license your copy it will run you about $200 currently. Once you use this system you will realize what a barging this is.

To actually to MySQL going you need to first download it. Simply go to the MySQL website http://www.mysql.com and go to the download section. There are always constant modifications and enhancements, the newest versions are called Alpha versions. Once you have downloaded and installed MySQL onto your web server you will want to change the password. Changing the password is always important for your own security, in a web environment. Then you can start to work with your actual databases.

Some helpful command lines are listed below with an explanation of what they are:

mysqladmin ping

-This allows you to see if the mysql daemon is running

USE mysql;

-Typing this allows you to use the mysql database

SHOW TABLES FROM mysql;

-This allows you to see the schema of the database

SHOW COLUMNS FROM user;

-This allows you to see a detailed list of columns of your database

These are some of the basic command that would be used in the very begging of working with MySQL. Delving more into MySQL allows you to build more specifics on your database. MySQL will allow you to make any web based database, by simply working with the given information you create.
