In order to achieve consistency in the data models, we need to have a naming convention for the ER diagrams. The following is the one used in this book. You can choose the one that you see fit. The goal here is to be consistent:

• Entity names must be singular and non-collective. For example, User and Team but not Users, Teams, nor User Table. One exception is Card List, which is actually the name in the requirement.
• Entity names must be in title case. For example, Board Member rather than Board member, nor board member.
• Relationship names must be in infinitive form. For example, create rather than creates and be created by rather than is created by.
• Attribute names must be in title case.
