SQL and You

If you have ever used the internet in any way you have interacted with SQL and probably don't know it. SQL is an amazing tool used in the backbone of the internet to access data. SQL is the communication line between data stored in a table and a user's screen where the data is wanted. Data such as your personal information on your facebook profile, your tastes as catalogued by Netflix, frequently searched terms from Google, or item types you've shown an interest in to Amazon. All of this information is stored neatly in tables in a server and SQL is the key to getting it where it needs to go.

SQL is a programming language that is a key part of website design. SQL commands can store information inputted by an individual, recall data from a table, and check various conditions in user and website variables to alter commands accordingly. SQL is highly versatile and can be incorporated directly into a websites backbone with html support. What this means is that the very code that describes the layout of a website can have pieces of SQL that handle movement of data from server to client.

SQL is heavily involved with targeted advertisements. Companies that have data on you such as facebook or google will store this information in a table. When web pages are loaded and advertisements are selected they are picked so that the advertisements have characteristics that have appealed to you in the past and have been documented in their databases.
