Recursions
-Ancestry checks (hierarchical and cyclic)
-Broken trees and orphans, Self-referential objects
-The difficulties faced with sub-typing recursions and intersecting recursions
-Recursive cardinality - 1:1, 1:M, M:M
-Use of both Static and Dynamic groups with recursion.

Dimension of Time
- Differentiating between different types of time-based rules
- Attributes and relationships over time
- Units of time and recursions of time
- Time overlap v Time underlap, Concurrent v Discreet, Disjointed v Continuous.
- Determining the appropriate granularity - Point or Period

Modeling rules on relationships and associations
- Associative entities – circular relationships, shared parentage, and other issues
- Alternatives for modeling constraints across relationships
- Advanced normal forms – how to quickly recognize potential 4NF and 5NF issues

Working with higher-level models
- Contextual, conceptual, logical models – what they are, who they're for, when we need them
- Definitions for each type of model, and common sources of confusion
- Avoiding the "deep dive into detail" – a three-phase method for data modeling
