What Is a Database?by Jeffrey Ober
People have kept track of information and data in many ways. Sometimes it was by using an elaborate file system, a ledger, or even a box. As computers become more popular and less expensive, many people find it easier to store information on the computer. The most common way to store large amounts of information with a computer is by using a database.
All computer databases are made up of tables. These tables contain records and each record is made up of some number of fields.
There are thousands of different types and manufacturers of computer databases. A few common examples are Microsoft's Access, Oracle and mySql.
Some computer databases are completely free, while others cost tens of thousands of dollars.
The terminology and technology behind a database makes it hard for the inexperienced to use. However, with training, an experienced person can learn the technology and work with a database quickly and easily.
Databases are used around the world by nearly every business in the twenty-first century, including vast government databases that contain huge amounts of information about citizens.
