What This Document Is
This is Milestone Four, Part One, a lab assignment for CIS321: Structured Analysis and Design at DeVry University. It focuses on initial data modeling tasks – defining entities and illustrating relationships between them – as part of a larger system design project. It was prepared for Professor David Apaw’s course.
Why This Document Matters
This milestone is intended for students enrolled in CIS321. It’s completed during Week 4 of the course and serves as a critical step in developing a comprehensive understanding of database design principles. Successful completion demonstrates an ability to translate business requirements into a logical data model.
Common Limitations or Challenges
This document represents an *early* stage in the design process. It focuses on identifying core entities and their relationships, but does not include database implementation details, user interface design, or process modeling.
What This Document Provides
The document includes an Entity Definition Matrix outlining key entities like Employee, Contribution, Site, and Department, along with brief descriptions of their attributes. It also presents a Logical Entity Relationship Diagram (ERD) visually representing the relationships between these entities – for example, an employee can have multiple emergency contacts or work at multiple sites. This preview *does not* include the full ERD details, nor does it contain any further analysis or refinement of the data model.
