Database
A
database is an organized collection of data. The data is typically organized to
model aspects of reality in a way that supports processes requiring
information. For example, modelling the availability of rooms in hotels in a
way that supports finding a hotel with vacancies.
Database
management systems are computer software applications that interact with the
user, other applications, and the database itself to capture and analyze data.
A general-purpose DBMS is designed to allow the definition, creation, querying,
update, and administration of databases. Well-known DBMSs include MySQL,
PostgreSQL, Microsoft SQL Server, Oracle, Sybase and IBM DB2. A database is not
generally portableacross different DBMSs, but different DBMS can interoperate
by using standards such as SQL and ODBC or JDBC to allow a single application
to work with more than one DBMS. Database management systems are often
classified according to the database model that they support; the most popular
database systems since the 1980s have all supported the relational model as
represented by the SQL language. Sometimes a DBMS is loosely referred to as a
'database'.

on the course database system and web applications and career opportunities
Course
Database and Web Application is ICT courses offered at the College of
Vocational Kuala Selangor. This course is intended to provide guidance and
training, and opportunities for new generations to develop a database with more
effective and useful with current technology and the development of an online
system that is increasingly popular in the era of globalization. Database
software used primarily in work that involves a lot of data storage. It allows
the collection of information that is programmed to allow users to find
specific information whether in whole or in part only. It also involves keeping
a record of information that can be maintained more easily to access data more
quickly.
BENEFITS
·Web applications do not require any
complex "roll out" procedure to deploy in large organizations. A
compatible web browser is all that is needed;·Browser applications typically
require little or no disk space on the client;·They require no upgrade procedure
since all new features are implemented on the server and automatically
delivered to the users;·Web applications integrate easily
into other server-side web procedures, such as email and searching.·They also provide cross-platform
compatibility in most cases (i.e., Windows, Mac, Linux, etc.) because they
operate within a web browser window.·With the advent of HTML5, programmers can
create richly interactive environments natively within browsers. Included in
the list of new features are native audio, video and animations, as well as
improved error handling.
