Data & Information: Understanding of how data, information and knowledge can be Information systems involves and functions by managing data, information and knowledge in any organization by mainly the modelling, storing and processing them. Different models and techniques are used in information systems to process, store, and organize and effective use of data, information and knowledge in organization.

This function is done by IS by designing the decision making path by creating and using the information needed to make that particular decision. Strategic Development: The link between Information system and the strategic development can be identifying by role of IS in identifying the needs and paths of strategic development and its importance in assessing the consequences. Designing the IS: Information System is designed in accordance to their deliverables, techniques and by counting the circumstances unique for each function or organization.

Use of technology in information system, has developed the tools, technologies and methodologies and have given it the new horizons by making it better.
