Database management system
• A database management system (DBMS) is a computer

(they take up little space).
Why to use database?
• It is very quick and easy to find information.

WHERE cus_phone='9911%';
Why use database?
• Data can be sorted easily, for example into ‘cus_fname' order.
Why to use database?
• It is easy to add new data and to edit or delete old data.
• Data can be imported into other applications .
• More than one person can access the same database at the same time -multi-
access.
• Security may be better than in paper files.
How to use database
• When a database holds details about people, it's likely to include their
first name, surname and their date of birth. In addition to this,
specialist information is stored depending on the database's intended use.
• The police have details of all known criminals in a database, crimes
they've comitted.
• Schools use a database to store details about their pupils, how many
days they've been off school sick.
How to use database
• A hospital will store details of all its patients in a database, eg a history
of their health issues.
• The Government uses a database to store records of people's income

Database security
• Database security deals with all various aspects of protecting the
database content, its owners, and its users. It ranges from protection
from intentional unauthorized database uses to unintentional database
accesses by unauthorized entities (e.g., a person or a computer
program).
Conclusion
• А database is an organized collection of data. Databases can store
information about people, products, orders, or anything else.
• Some of the more popular database software applications include
desktop solutions like Microsoft Access and FileMaker Pro and server
solutions like MySQL, Microsoft SQL Server and Oracle.
• Databases can store very large numbers of records efficiently
