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.
According to <span>Richard Dawkins, culture is a population of memes which are just "copy me" programs.
Just as genes reproducing themselves, memes are actions, behaviors, units of culture that are replicated through language or observation.
This way of describing culture has some important ramifications:
first, culture is not a way of thinking that a certain population share, but in opposition is something we have in common with people with our same culture;
second, where an individual experiment some degree of conflict between the cultural norms and its belief, this conflict is not caused by an external force but instead is a conflict that is taking place in their heads;
third, if you view culture as a similarity between people, like brown hair, it is much easier to remember that perspective matters;
lastly, this way of viewing culture gives us a measurable way of thinking about how culture is spread among different individuals.

<span>Rachel and matt are in their first year of middle school. statistically, one would expect their academic achievement to "decline".
Student performance is identified with inspiration to learn. As inspiration for the most part decays amid lower secondary education, one may anticipate that execution will decrease too during this period. However, it has been misty whether this example exists. In the present examination, we inspected student performance amid the early years of secondary education from a formative point of view.
