The information systems lifecycle

• Information system

The resources that enable the collection, management, control, and dissemination of data/information throughout an organization.

An information system not only collects, manages, and controls data used and generated by an organization but enables the transformation of the data into information.

The essential component at the heart of an information system is the database that supports it.

• Design (including database design)
• Prototyping
• Implementation
• Testing
• Conversion
• Operational maintenance
