Introduction to SQL
SQL, also known as Structured Query Language, is a collection of data that resides in a file called a database. SQL is similar to other database languages, such as Oracle. For simplicity we’ll stick with SQL at this time.
SQL is a database language used to access and/or modify your database information.
A Few of the SQL commands we’ll cover in future articles are SELECT, DELETE, UPDATE, INSERT, WHERE, ORDER, plus more advanced topics such as JOIN, GROUP, and more.
