Final answer:
To convert a recursive relationship to a relational table, one can use a table with a foreign key that references its own primary key, thereby establishing a chain of relationships. For example, a 'Person' table with ID, Name, and Parent_ID can be used to trace a matriarchal lineage by linking each daughter to her mother through the Parent_ID.
Step-by-step explanation:
To convert a recursive relationship to a relational table in a database, you need to account for the data structure where a record is related to another record of the same type, such as a hierarchical relationship between mothers and daughters. One way to handle this is through the use of a foreign key that references the primary key of the same table.
For instance, imagine a table 'Person' with columns ID, Name, and Parent_ID. Each person is a record with a unique ID. In the case of mothers and daughters, if we are depicting a strictly matriarchal lineage, every daughter (who is a mother as well) would have her own ID, but the Parent_ID field would reference the ID of her mother. This forms a chain of recursive relationships, where you can follow the Parent_ID field to trace the lineage back through generations.
An example entry for a daughter with a mother would be something like:
- ID: 2
- Name: Jane Doe
- Parent_ID: 1 (assuming ID 1 is Jane's mother)
By establishing these links within the table, we construct a family tree that can be queried to explore relationships. Recursive relationships are common in scenarios where hierarchy or lineage is important, such as organizational structures or family trees.
