At the end of this session you should be able to:
The various information systems & their evaluationInformation Infrastructure and Architecture
DESCRIBE

WEB BASED SYSTEM?
What is a…
IN OTHER WORDS…
YOU CAN HAVE A… SOFTWARE / APPLICATION / SERVICE
ON A SERVER…

maintenance)

controlling of the infrastructures and the organization’s portfolio of applications must be done with great skill

• Understand the differences and implementation for various Web Based Systems and Architecture
• Know the importance of Information Systems and how is it managed
