Databases drive nearly every Internet and Intranet Web site. Global IT’s Introduction to SQL and Database Design class teaches you how to master their power through a thorough grounding in SQL and sound database design fundamentals.

This course is designed for people with no relational database experience. The database that we use for the class is MySQL, an open source product that is gaining in popularity in the industry and SQL Server. However, the concepts are basic enough that they transfer easily to any standard database product that abides by the ANSI standards.

SQL (Structured Query Language) is used to retrieve, edit, remove and add data in relational databases. SQL programmers define and create relational database structures including tables, views etc.Good SQL skills are always in demand and are useful in a number of careers including database developers, report writers, business analysts, computer programmers, web developers, testers, data analysts, etc. Because an increasing number of companies are storing and analyzing an ever increasing amount of corporate data, the demand for SQL or database skills will continue to increase.

SQL has a shorter learning curve when compared to other skills like business analysis or computer programming or testing. Part of the reason is that SQL is a well-defined, standardized language that has been around for a number of years.
