My. SQL for Absolute Beginners.Tutorial by Matt Doyle Level Beginner Published on 2.August 2. 01. 1Categories Never used My.SQL before Start here This tutorial walks you through the very basics of My.SQL and SQL databases.Learn how to install My.SQL, how to issue commands, and how to create and use databases.A database is an essential part of most websites and blogs, but setting up and using a database can be a daunting task for the beginner web developer.In this tutorial youll learn in simple terms how to install, set up, and use a My.SQL database on your computer.This will give you a good grounding in My.SQL that youll find useful when you start developing database driven websites using PHP, Ruby, or your language of choice.Youll explore the following areas in this tutorial The concept of a database, and why databases are useful.The advantages of using My.SQL to manage your databases.How to install My.SQL on your computer.Using the My. SQL Monitor program to send commands to your My.SQL server. How to create a database and table.SQL Structured Query Language, and what its used for.Adding records to a table, and retrieving records from a table.Ready to start exploring My.SQL Lets go What is a database A database is a structured collection of data.Here are some typical examples of databases An online store database that stores products, customer details and orders.A database for a web forum that stores members, forums, topics and posts.Who should read this manual This manual is targeted for the person responsible for evaluating, installing and maintaing MantisBT in a company.A database for a blog system, such as Word.Press, that stores users, blog posts, categories, tags, and comments.The software that manages databases is known as a database management system, or DBMS.My. SQL is an example of a DBMS.Rather confusingly, DBMSs are often called databases too.Strictly speaking though, the database is the data itself, while the DBMS is the software that works with the database.There are many different ways to organize data in a database, known as database models.One of the most popular is the relational model, which is what My.SQL uses along with Postgre.SQL, Oracle, Microsoft SQL Server, and other common systems.Consequently, My.SQL is known as a relational database management system, or RDBMS.The following diagram shows how a database, the DBMS, and your websites code interact with each other.A database left is a collection of related data, managed by a DBMS such as My.SQL centre. Web scripts right communicate with the DBMS in order to insert, update, delete and retrieve data in the database.Why use a database If you havent used a database for your website before, you may have stored data in text files such as comma separated value CSV files.Heres an example of a CSV file.Address,first.

While this technique is fine for simple data structures and small amounts of data, you quickly run into problems as your site grows.Searching and updating a very large text file is slow and prone to corruption.Whats more, things start to get messy when you want to link records together, such as linking a customer record to the orders that the customer has made, and then linking each order record to the products that are in the order.Relational databases are designed to take care of all these problems.Here are some reasons to use a database instead of text files Theyre fast.Databases use indexes, or keys, to find records of data extremely quickly.For example, once you add a key to an email.Address field for member records in a database, you can retrieve a member record based on the members email address almost instantly, no matter how many millions of members you may have in your database.Theyre reliable. A DBMS ensures that the data in the database is read and written reliably, without corrupting the data.Many DBMSs allow you to use techniques like locking and transactions to ensure that records are inserted and updated in a predictable way.They let you link records together.Relational databases let you store different types of data in groups known as tables.You can then link data together across tables.For example, you can create a customers table and an orders table, then link a customer record to all the order records associated with the customer.The ability to link records across tables lets you create complex databases with lots of different types of related data.Installing Phpmyadmin On Solaris 10 Download' title='Installing Phpmyadmin On Solaris 10 Download' />Why use My.SQL You now know why databases are useful, and how they can help you build complex websites and web apps.But why use My. SQL in particular There are many great DBMSs out there, including My.SQL, Postgre. SQL, SQLite, Oracle, and SQL Server, and all of them can be used for most web development purposes.That said, My. SQL does have a few advantages for web developers compared to some other systems Its open source, which means its free for anyone to use and modify.Its widely available.My. SQL can be installed on many different platforms, and it usually comes standard with most web hosting setups.Its easy to use. Setting up and working with My.SQL databases is relatively straightforward.It works well with PHP.As of version 5. 3, PHP has a native My.SQL driver that is tightly coupled with the PHP engine, making it a good choice for PHP coders.Each DBMS has its own strengths and weaknesses.For example, Postgre.SQL is also open source, is very stable, and has a great community behind it.SQLite is extremely fast and self contained and is also free, while Oracle and SQL Server have a lot of enterprise level features that make it a good choice for large organizations.Installing My. SQLAs I mentioned above, most web hosting accounts come with My.SQL pre installed.However, if youre developing websites using My.SQL, you also want to have the My.SQL server running on your own computer, so that you can create and test your databases and code without needing to upload files to your live server all the time.There are two main components to My.SQL The My. SQL database server, mysqld.This is the My. SQL DBMS that does the actual work of managing your databases.It runs all the time in the background, accepting connections from client programs, web scripts and so on.Various client and utility programs.These include mysql, the command line My.SQL Monitor client that youll use later in the tutorial to issue commands to the server.Youll also find programs like mysqladmin for administering My.SQL databases, and mysqldump for exporting and backing up databases.In addition, many My.SQL installs include documentation, header files for developers, and the My.SQL test suite. There are many ways to install the My.SQL server and associated programs.Here are three ways you can do it Using an official My.SQL installation package.There are prebuilt packages available for many different operating systems, including Windows, Mac OS X and Linux.The basic procedure is to download the package file, extract it, and run the installer.See the documentation for the exact steps.Using a Linux package manager.Many Linux distros come with a package manager for example, Ubuntu includes the Ubuntu Software Centre that makes it easy to install My.SQL, along with PHP, Apache and other web development software.See your distros documentation for details.Installing an entire LAMPWAMPMAMP package.This is arguably the easiest way to install a complete My.SQL based development setup on your computer.These packages contain all you need to start building database driven sites, including the Apache web server, My.SQL, and PHPPerl, hence the acronym AMP.The L, W and M stand for Linux, Windows and Mac OS X respectively.Since everythings installed in one go, youll find that Apache, My.SQL and PHPPerl all play nicely together, with little or no further configuration required.If you want to get up and running as quickly and easily as possible, Id personally recommend downloading and installing XAMPP.This LAMPWAMPMAMP package is available for Linux, Windows, Mac OS X and Solaris, and automatically installs and sets up Apache, My.SQL, PHP and Perl on your computer.Whats more, its easy to uninstall everything later if you want to.To install XAMPP Visit the XAMPP homepage and click the link for your operating system Linux, Windows, Mac OS X or Solaris.Follow the steps on the page to download, install, start, and test the XAMPP system on your computer.Other popular packages similar to XAMPP include Wamp.
