Geek Sync | Become a Better Data Modeler. Part 5: Write Effective Entity Definitions

Presenter: Steve Hoberman

Data modelers need to write effective entity definitions because they play a vital role in ensuring that the data model is accurate and easy to understand for all stakeholders involved. Entity definitions describe the purpose and characteristics of each entity in the data model, providing essential context and information for users. Effective entity definitions are crucial for data modelers. They help ensure communication, maintain data integrity, provide documentation, reduce ambiguity, and facilitate collaboration among stakeholders.

Here are some reasons effective entity definitions are important for data modeling:

  • Communication: Well-written entity definitions help convey the meaning and purpose of each entity to stakeholders, including developers, analysts, and business users, ensuring everyone has a consistent understanding of the data model.
  • Data integrity: Effective entity definitions explain the attributes and relationships of each entity, helping maintain data integrity by ensuring that users interact with the data model as intended.
  • Documentation: Entity definitions serve as valuable documentation for the data model, making it easier for users to navigate, understand, and maintain the model.
  • Reduced ambiguity: By defining the purpose and characteristics of each entity, data modelers can minimize ambiguity and confusion, leading to fewer errors and misunderstandings.
  • Facilitate collaboration: Effective entity definitions enable better collaboration between different teams, such as data modelers, developers, and business users, by providing a common language and understanding of the data model.

Definitions are often not given the attention they need. Most definitions are vague and up for interpretation, leading to inconsistent interpretations of the data model. How do you write a clear, complete, and correct entity definition? Learn how in this Geek Sync. Steve reveals tips for writing effective definitions and for improving existing definitions, to ensure that the definitions support the precision of the data model. Expect an interactive and entertaining session!

Speaker: Steve Hoberman has trained more than 10,000 people in data modeling since 1992. Steve is known for his entertaining and interactive teaching style (watch out for flying candy!), and organizations around the globe have brought Steve in to teach his Data Modeling Master Class, which is recognized as the most comprehensive data modeling course in the industry. Steve is the author of nine books on data modeling, including the bestseller Data Modeling Made Simple. One of Steve’s frequent data modeling consulting assignments is to review data models using his Data Model Scorecard® technique. He is the founder of the Design Challenges group, Conference Chair of the Data Modeling Zone conferences, and recipient of the Data Administration Management Association (DAMA) International Professional Achievement Award.


There are several ways to become a better data modeler:

  • Gain hands-on experience: The best way to learn data modeling is to get hands-on experience by working on real-world projects. This will give you the opportunity to develop your skills, learn from your mistakes, and see how data modeling works in practice.
  • Take courses or attend workshops: Taking courses or attending workshops can provide structured learning and help you develop a solid foundation in data modeling principles and techniques. Look for courses that cover topics like database design, data modeling methodologies, and normalization.
  • Read books and articles: There are many books and articles available on data modeling that can help you deepen your knowledge and understanding. Look for books that cover specific topics of interest, such as database normalization, data modeling patterns, and database design best practices.
  • Seek mentorship: Finding a mentor who is an experienced data modeler can help you learn from their experience and get feedback on your work. They can help you identify areas for improvement, provide guidance, and offer advice on how to tackle complex problems.
  • Participate in online communities: Participating in online communities, such as forums and social media groups, can help you connect with other data modelers, ask questions, and share your own knowledge and experience.

Ultimately, the best way to become a better data modeler is to practice regularly, seek out feedback and guidance, and stay up-to-date with the latest trends and best practices in the field.
