Relationships Between Tables

POCO DataSet does not enforce relationships between tables internally. Instead, it allows applications to define foreign keys, logical links, and other relationships based on their specific needs without rigid constraints.

Types of Relationships

• Foreign key relationships
• Logical links (non-key references)
• Natural keys
• Lookup relationships

Why Relationships Are External

Thisapproach maintains POCO DataSet’s lightweight philosophy. Applications can implement relationship behavior as needed—whether in service layers, UI components, or rule engines.
