SQL (Structured Query Language) began life as SEQL (Structured English Query Language) at IBM, following an article on the concept of relational databases by IBM researcher E.F. Codd. This was back in 1970. Reaction to his article began a great deal of research, culminating in IBM's SQL database language. SQL is still called Sequel by many in the field, even after the name was changed from SEQL to SQL, supposedly on legal grounds.

By the late 1970s, similar products were developed that became Oracle and Ingres. However, by the 90s, SQL products became so numerous that they were the unofficial standard for database management, at least for medium to large organizations. This was particularly true on UNIX platforms and mainframes. Recently, SQL seems to have attained official status as "the standard," although no commercial product really follows the actual ANSI standard for SQL.

What is SQL used for, outside of maintaining internal databases at a large business? The ordinary consumer could access an online catalog of clothing and accessories, browse online bookstores, or research airline flights to various cities. The customer could then place an order or make a reservation. Of course, only the larger companies can afford the investment or the monthly cost of such a resource. Smaller companies would do fine with MS Access, which can run on a shared web host using Windows 2000. If the host is Linux or UNIX, a database called MySQL will handle the data nicely.

SQL Server Training

SQL databases are usually accessed by an employee looking for information or verification of a transaction. Classroom instruction is sometimes provided by the employer, but too often, the employee flounders around, learning by OJT or from a coworker. However, administrators, database designers and system engineers require a much different level and type of training, through beginning to advanced, to be successful in their responsibilities. It helps if these individuals have at least a working knowledge of recent Windows Server and Professional editions.
