To identify data requirements, the project team starts a process of investigation. This process involves gathering and analyzing data from users, systems, and documentation to determine the current state and desired future state of the solution. Gathering data involves: Determining what information is needed to identify the data, functional requirements, and nonfunctional requirements. Identifying sources from which to obtain relevant and supporting information. Sources can include people, systems, and systems-support documents. Looking at source information from different perspectives to ensure that all the relevant information is gathered from a particular source. Gathering the information needed to determine requirements from the identified sources. Information can be gathered in several ways:. | Module 3 Using a Conceptual Design for Data Requirements Module 9 Data Storage Considerations Module 1 Course Overview Module 3 Using a Conceptual Design for Data Requirements 47 Overview Slide Objective To provide an overview of this module s topics and objectives.
