Answer:

Rating a favorite movie on a digital streaming site, (Option A is correct)

Explanation:

Rating a favorite movie on a digital streaming site might contribute to recommendations you see online such as on videos streaming site. After viewing the movie, you rate the movie to like or dislike, or rate on five stars. Your this rating might contribute to recommendation for others. If a movie has a very low rating, it means that this movie is not recommended for you than the movie which has the highest rating by people. For example, most probably you like to watch the movie on streaming site that has the highest numbers of likes and views

Other actions might not contribute toward recommendation:

Searching an item using the search engine might not contribute toward the recommendation you see online. Because when you search in a search engine, you may not rate the item you are searching for in it.

Furthermore, purchasing a new t shire from an online retailer may not contribute toward recommendation because you purchased the t-shirt and may not rate it.

All of the above option is only acceptable, when all options allow you to rate online or recommend online. Therefore, only first option allow you to rate your favorite movie on a digital streaming site that might contribute towards recommendation you see online.

Vera_Pavlovna [14]

Answer:

True. A goal programming problem

Explanation:

Goal programming is an optimisation technique to solve problems with multiplicity of objectives, which are generally in commensurable and they often conflict each other in a decision making horizon.In a certain programming environment, optimisation of a set of objectives is involved there in the decision situation. Here, instead of optimising them directly, achievement of the assigned target values called aspiration levels of them is considered. In goal programming method, the unwanted deviations (under and / or over) from the aspired levels are minimised in the goal achievement function (objective function) to reach a satisfactory solution in a crisp decision environment

What is a foreign key and how does it provide referential integrity?

Step2247 [10]

Answer:

By definition a foreign key of table A is a primary key of another table B, thereby establishing a link between them.

To provide referential integrity you can use these referential actions:

Cascade: If rows in table B are deleted, the matching foreign key columns in table A are deleted.

Set Null: If rows in table B are deleted, the matching foreign key columns in table A are set to null.

Set Default: If rows in table B are deleted, the matching foreign key columns in table A are set with the default value of the column.

Restrict: A value in table B cannot be deleted or updated while as it is referred to by a foreign key in table A.
