• The data life cycle consists of the acquisition and the usage parts

Usage ActivitiesData Acquisition

Data Acquisition and Usage Activities(Select View Show, click to step through PPT)

• The acquisition part processes the sensory data by firmly linked procedures

The focus is on data usage activities

• The usage activities are more iterative, dynamic procedures • The collected and cleaned data are stored in the repository

Data Repository

• The usage cycle transform data into knowledge for decision making
