Databases

What is it?
A database is a collection of logically organized electronic information.

How Does It Work?

In its most rudimentary form a database is defined by something called a table or by multiple tables. A table looks a lot like a spreadsheet. Unlike a spreadsheet a table has strictly defined columns which define the type of data they can hold.

Data can be added to a table, using an insert.
Data can be retrieved from the tables, using a select.
Existing data can be modified, using an update.
Data can be removed, using a delete.

In a real world implementation, a database for a online retailer might have a table for customers and another table for products they sell. Various server technologies can add, read, change, and delete database information.
