Summary

Databases provide us with a structured and organized manner in which to store data. One of the most popular types of database models is the relational database. Relational databases use tables as a way of representing relationships between entities. SQL is the language used to communicate with relational databases. Although you do not need to be a SQL expert to develop ColdFusion applications, you do need a basic understanding of the SQL language.

Our discussion of SQL should get you started; but if you are not familiar or comfortable with SQL, we strongly recommend that you invest in any one of the excellent texts on the market that cover the topic in detail. Keep in mind that most DBMSs have added proprietary extensions to the basic SQL, so it is strongly suggested you purchase a text that focuses on the database system with which you are working.
