Показать описание
An Entity Relationship Diagram (ERD) is a data model describing how entities (or concepts or things) relate to one another. When created by business analysts, ERDs can be used to understand the business domain, clarify business terminology, and connect business concepts to database structures.

You'll discover:

*What is an ERD (Entity Relationship Diagram) and how they can be useful models for business analysts.
*The 3 key elements of an ERD (with visual examples).
*How to build a simple sample entity relationship diagram by starting with a business glossary, or looking for nouns in your use cases, business process models, or other requirements documents.
*Why I don't often start right in Visio, or any visual modeling tool, but use pencil and paper first.
*How to engage business subject matter experts in collaboratively building an ERD, and how to introduce them to what might seem like an overly technical modeling technique.
*How ERDs can sometimes work magic for your team's understanding and quickly resolve tricky data-design issues

I really love your descriptions. They make a lot more sense than the book I'm reading for the Database class I'm taking.

Thank you for this info!! Can we reverse engineer and build a logical data model from a physical data model?
