A limiting factor in design is any constraint that restricts the choices or options available to a designer. This could include budget limitations, time constraints, client preferences, technical restrictions, or environmental considerations. Designers must work within these limitations to create practical and effective solutions.
To alter foreign keys in Oracle, you can use the ALTER TABLE statement. To modify an existing foreign key constraint, you typically need to drop the existing constraint first using ALTER TABLE table_name DROP CONSTRAINT constraint_name, then add a new foreign key constraint with the desired modifications using ALTER TABLE table_name ADD CONSTRAINT constraint_name FOREIGN KEY (column_name) REFERENCES other_table (other_column). If you only need to disable or enable the constraint without altering it, you can use ALTER TABLE table_name DISABLE CONSTRAINT constraint_name or ENABLE CONSTRAINT.
