List the capitaUzed nouns in all your Business Statements. 2. Write a definition for each. 3. Go back over your collection of business rules, pull out any other nouns that might represent entities, and list them. 4. Beside each one, if it doesn't look like an entity, explain why it isn't an entity. 5. If you find a new entity, write one or more appropriate Business Statements for it. 6. Save the lists, definitions, and explanations in your project folder. Congratulations! You now have a basic entity roster, you have clarified your thinking about the problem, and you have a record of that thinking: something that you will find useful to refer to later on, as you revise the data model.
