Last Updated : 11 Mar, 2024 Improve Improve Like Article Like Save Share Report Answer: Convert weak entity to strong by adding a primary key and ensure independence through normalization and composite keys. Follow these steps to convert weak entity into strong entity: Identification of Weak Entity: Recognize entities in the database model that lack a unique identifier and are dependent on another entity for identification. Primary Key Definition: Assign a unique primary key to the weak entity, incorporating attributes that, when combined with a discriminator, ensure its distinct identification. Establishing a Strong Relationship: Forge a robust relationship between the weak entity and an identifying entity, ensuring that the weak entity’s identity is solidified by the identifying entity. Ensuring Total Participation: Guarantee that every instance of the weak entity participates entirely in the identifying relationship, establishing a clear association with the identifying entity. Attribute Normalization: Normalize attributes to eliminate redundancies, streamlining the structure and optimizing data integrity. Consideration of Composite Key: Contemplate the use of a composite key for the strong entity, combining the primary key of the weak entity with additional attributes for comprehensive identification. Independence Verification: Verify, the transformed strong entity can exist independently of the identifying entity, ensuring autonomy within the database structure.
