Ideas in this flowchart
- Foreign keys and references between records
- A foreign key stores an identifier
- The identifier belongs to another related record
- The foreign key represents a reference to a related record
- One record can point to another record
- The record can point to its parent
- The record can point to another associated entity
- These references allow software to use the relationships
- The software reconstructs structured information
- The result is structured information from related records
- These references also allow verification
- The software verifies the connections
- The connections are connections between records
- The verification determines whether the connections are valid
- Related records can be reconstructed and validated
