Which of the following actions cause an indirect change to a database table requiring a table conversion? (Select two correct answers)

In the context of actions that lead to an indirect change in a database table necessitating a table conversion, the choice regarding shortening the length of a domain associated with a data element is appropriate. When a domain's length is reduced, it may impact the actual data stored within the database table, especially if existing entries exceed the new shorter length. This alteration in the data structure can lead to data truncation or loss, which is why a table conversion is required to manage these changes safely.

The choice concerning the deletion of a field from a structure included in the table definition also qualifies as a valid action necessitating a table conversion. Removing a field can fundamentally change the structure of the database table, and since the field is an integral part of the structure, its absence can affect how data retrieval, storage, and relationships with other tables operate. Such alterations usually require a conversion to maintain data integrity and ensure that the database behaves as expected.

While renaming a field or changing field labels might make adjustments in the code or the interface more intuitive or consistent, these actions do not necessitate the physical restructuring of the underlying database table. Renaming remains within the existing data structure, and changing labels is more about user interface representation without implications for the data model itself.
