What is Database?
A database is an organized collection of data, generally stored and accessed electronically from a computer system. Where databases are more complex they are often developed using formal design and modeling techniques
How Are Databases Used in the Real World?
Databases are obviously used in business applications and financial transactions; however, databases are not just used for business applications. Your grocery store, bank, video rental store and favorite clothing store all use databases to keep track of customer, inventory, employee and accounting information. Databases allow for data to be stored quickly and easily and are used in many aspects of your daily life.

The move from paper to computer databases was a huge leap in information management and storage. Databases are much more efficient than paper storage in that they take up less space, are easily accessed by multiple users at once and can be transferred long distances with virtually no delay. The use of databases allowed for the rise of corporate infrastructure, credit card processing, email and the Internet. Databases allow for data to be shared across the world instead of being housed in one location on a physical piece of paper.
