The purpose of contraints is not to curtail or abolish freedom but to preserve and enlarge it. Where there is no contraints, violence and anarchy will prevail jeoperdising thd cultivation of liberty. So contraints are essantial components of freedom.
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.

Yes, an applied constraint can typically be deleted, but the method depends on the context, such as the software or system being used. In databases, for instance, you can drop a constraint using SQL commands. In programming or modeling environments, you may need to modify the settings or use specific functions to remove it. Always ensure that removing a constraint does not violate any integrity rules or lead to unwanted data issues.

A constraint is something which constrains, which inhibits freedom in some way. Constraints can be physical, like a straitjacket, or legal, such as laws and regulations which restrict behaviour, or social, such as rules and customs of conduct.
