What is SQL, who uses it, and why do I need to know about it? This article provides answers to these questions.

SQL is an abbreviation for Structured Query Language. It is a computer language that allows communication with a database. The American National Standards Institute (ANSI), a national not for profit organization, assists manufactures in setting up standards that allow US products to be used worldwide. SQL is defined, by the ANSI, as a standard language for relational database management systems. This is important for commerce and scientific purposes. In other words, this allows a person to manage, adapt, and use a database. There are some commercially available programs that use SQL.

SQL is used by primarily by database programmers, website and windows developers, and people who set-up e commerce applications. In SQL, a table is set up, and the program allows information to be taken from the database, and put into the table. A table is identified by name, and is made up of columns and rows. Columns are horizontal, and contain the descriptive information. Rows are vertical, and contain data. This example is greatly simplified. The basic content of a SQL class defines SQL, explains table basics, how to select the data for the table, putting the data in, and how to modify (change, add or delete) information.

There are many ways in which you may pursue SQL training. Instructor led courses are widely available. There are also SQL courses online. You may buy a book to learn SQL, or DVDs also. Many training courses are available online. All these have advantages and disadvantages. Instructor led classes allow communication with a teacher, and hands on teaching. On the other hand, they are very expensive, and somewhat time consuming-usually last from three to five days. Online instruction is cheaper, but can still cost hundreds of dollars. A DVD program is less expensive than either or those two choices, but it is not interactive. The least expensive way to learn SQL is to buy a book. Be sure to choose one with good reviews.

I am not a programmer or a website designer, why do I need to understand it? SQL has a huge field of applications, and you will need to know at least enough to answer questions intelligently. Many retailers have websites where you can shop, and one trend predicted is that even small businesses will be doing so also. Working with a designer, you will need to be able to define the categories and assist in the data management of the site. Paying someone to maintain this for you is very expensive. Whether you use the database to acquire information, or to input new data, a basic understanding will be helpful. Schools use databases to manage student information. Businesses use it to keep track of inventory. Online stores use it to populate shopping carts. Police officers search for information to help them solve crimes in national databases.

In summary, SQL training is a very useful thing now, and for the future.
