Database Managements:
Computer database is a structured[citation needed] collection of records or data that is stored in a computer system so that a computer program or person using a query language can consult it to answer queries. The records retrieved in answer to queries are information that can be used to make decisions. The computer program used to manage and query a database is known as a database management system (DBMS). The properties and design of database systems are included in the study of information science.
A typical query could be to answer questions such as, "How many hamburgers with two or more beef patties were sold in the month of March in New Jersey?". To answer such a question, the database would have to store information about hamburgers sold, including number of patties, sales date, and the region. The term "database" originated within the computing discipline. Although its meaning has been broadened by popular use, even to include non-electronic databases, this article is about computer databases. Database-like collections of information existed well before the Industrial Revolution in the form of ledgers, sales receipts and other business-related collections of data.
