DB Dev. :: 
SQL (Structured Query Language) is a standardized language for defining and manipulating data in a relational database. In accordance with the relational model of data, the database is perceived as a set of tables, relationships are represented by values in tables, and data is retrieved by specifying a result table that can be derived from one or more base tables.
Queries take the form of a command language that lets you select, insert, update, find out the location of data, and so forth.
If you are going to use SQL in your applications, you will need to become very familiar with the TQuery, TADOQuery (and similar) components.
