Database Administrators

Database Administrators use database software to store and manage information. They will often set up database systems and are responsible for making sure those systems operate efficiently (usually referred to as database performance tuning). They also make sure that the data they store is backed up regularly, stored effectively, and that the data is secure from unauthorized access. Ensuring the data is available, by maximizing database up time, is also an important function of the database administrator.

Database Administrator Career Path

Database administrators often promote to a senior database administrator and then into a strategic management role within the company, such as a MIS Manager and eventually even on to a Chief Technology Officer role. Some DBAs specialize in a certain area, such as database security, and become experts in that particular area.

Database Definition

A database is a set of data that has a regular structure and that is organized in such a way that a computer can easily find the desired information

Data is a collection of distinct pieces of information, particularly information that has been formatted (i.e., organized) in some specific way for use in analysis or making decisions. 

A database can generally be looked at as being a collection of records, each of which contains one or more fields (i.e., pieces of data) about some entity (i.e., object), such as a person, organization, city, product, work of art, recipe, chemical, or sequence of DNA. For example, the fields for a database that is about people who work for a specific company might include the name, employee identification number, address, telephone number, date employment started, position and salary for each worker.
