Data Model for Turtle Conservancy   

An Access Database is available.

We might also design a Data Mart which is very useful for providing data for Reports and Business Intelligence.

We would be glad to have your comments.

If you are new to Data Models, this page of my new Tutorial will help you understand the Data Model.

The Turtle Conservancy organises a number of different kinds of Events :-
1) The Turtle Ball in New York City.
2) Conserve species in their natural habitat, including land acquisition.
3) Maintain captive breeding programs to help restore natural populations.
4) Monitor and help to prevent trade that threatens species..
5) Outreach and spreading global awareness.

Comments in LinkedIn
When I posted a question on LinkedIn to ask for comments on whether my approach reflected Best Practice in Data Modelling, I received a comment from Jeff Albro at Boston University (Thanks, Jeff) recommending I check out this article from Ralph Kimball on 'Declaring the Grain'

After I read it, I realise that I always start with a Dimensional Model or Data Mart with Facts at different levels to reflect different levels of summarisation - ie different levels of granularity.

Subsequently I can create separate Data Marts, each with its own granularity.
Here is an example showing Federated Data Marts
As a result, I decided, in this instance, to call my Facts 'Factoids' !!! I would welome any comments at
