Databases - SQL

Overview

Structured Query Language (SQL) is used for database programming. Databases are used to store information, and SQL has been important for the development of online databases including blogs and online photo galleries. SQL was developed in the 1970s in response to growing needs to store information electronically. SQL can be used to insert, update, delete, or manipulate data. Large organizations make use of SQL to store and analyze their database records.

SQL was developed by IBM. In contrast to previous database programming languages, SQL allows the end user to analyze their own data. Large organizations could use their SQL database to create customized applications and reports. Query functions allow users to sort and organize their data by selecting exactly what they need.

The costs associated by SQL vary by an organization's needs. A company might choose to develop their own SQL database, or they may choose to hire a consultant. You might need to pay for a customized database, or you may need to pay a programmer on a consistent basis. If you do not need a customized database, you may choose to purchase database software that was developed using SQL.
