1. Object-role Modeling Fundamentals: A Practical Guide to Data Modeling with ORM
Author: Terry Halpin Date Accessed: June 19, 2020

This ebook talks about what object-role modeling (ORM) is in depth and how to model it
for business domains. ORM is a fact-based approach. Every object has a role it plays. The methods discussed throughout help business owners understand this structure. This book also includes
the 7 steps for the ORM Conceptual Schema Procedure, which is used to design fairly small
schemas to suitably manage a single unit, as well as examples.
2. Temporal Capabilities in Support of Conceptual Process Modeling using Object-Role

Temporal modeling is provided to different conceptual modeling languages, including
Object-role Modeling. Since ORM doesn’t address Facts temporal properties, this paper provides
an ORM overlay methodology to lay the foundation for conceptual modeling structures. It includes steps for these capabilities supporting conceptual process modeling using ORM. This
document is loaded with different examples to further explain every aspect of this approach.
3. Object-Role Modeling: an Overview Author: Terry Halpin Date Accessed: June 22nd, 2020
http://www.orm.net/pdf/ORMwhitePaper.pdf
This paper talks about ORM in detail, the pros and cons about it. The seven steps for
CSDP are included with plenty of examples involved and explained. Towards the end of the paper, Halpin talks about conceptual queries. He mentions how ORM is ideal for information
querying and talks about it a bit. This is a perfect example of ORM being used in the real world
for a query tool called “ActiveQuery”.
4. Modeling Business Rules using Fact-Orientation and Object-Orientation
Author: Dr. Terry Halpin Date Accessed: June 22nd, 2020
http://www.orm.net/pdf/drma99.zip
This powerpoint provides straight to the point facts about ORM. It compares ORM to UML and
typical ER. Each of their constraints are listed. A schema for each is included. Details of each are
provided, which will help with making comparisons in my paper. Examples of the different characteristics are also provided for deeper understanding.
5. Static and Dynamic Aspects of Application Domains: An Inductively Defined Modeling
Technique That Allows Decomposition Authors: Theo P. van Der Weide, Fiona P. Tulinayo and
Patric van Bommel Date Accessed: June 22nd, 2020
This paper introduces another way of ORM: an inductive definition. This allows for the integration of different methods. It’s not meant to create a completely new method. Background information and history of ORM is discussed in the second section. Conceptual language and constraints are also mentioned. In depth explanations are made with examples for each step of the
way.
