To enforce referential integrity, the database can return an error instead of doing the requested action or do the requested action and do the related changes to the related tables
Thus the answer is either a or b.
Explanation:
When the given data base in a table is valid and if it is consistent then it is called as referential integrity and it also refers to the consistency within the relationship. This type of database is much important because it will keep us introducing to the errors in the databases and it also checks if the reference from one table is equal to the other table.
The main function is to prevent the users from entering the wrong and inconsistent data. So in referential integrity the database will return the error instead of doing the required action or it can do the related changes to the related tables.
Several ways for sure,
Hope this helps you! Have a great day. :)
Answer:
Heritable traits that enhance survival will become progressively more common in succeeding generations.
Explanation:
Charles Darwin's theory of evolution developed many ideas; among them we find the "Adaptation", which describes just what the exercise explains: the "inescapable conclusion" that individuals in a population will have unequal reproductive success, so that those whose traits best enable them to survive will leave more offspring. In other words, among a species, the individuals who have the best heritable traits will be able to have more offspring, and, therefore, those traits will be more and more common in the following generations.
