Hello and welcome to Programming Video Tutorials. In this tutorial we will go through SQL, the Structured Query Language. SQL is the standard computer language for accessing and manipulating databases through database management systems such as MySQL and Oracle.
In addition to the standard SQL that this tutorial is about. Most database programs also provide their own language extensions. The database management system is a computer program that acts as a hub between the databases and the programs that are going to use them.
SQL is the language we use to communicate with a database system. Databases provide fast and efficient access to save and load data. The data is contained in tables and each table in turn contains rows and columns. The entry in the row is called a record and it contains a field for every column.
