Question
Which of the following best defines the principle of encapsulation in object-oriented databases?Storing objects in a flat file systemThe integration of data with methods that operate on that dataThe use of foreign keys to link tablesNormalization of objects into tables
Solution
The principle of encapsulation in object-oriented databases is best defined as "The integration of data with methods that operate on that data".
Here's a step-by-step explanation:
-
Encapsulation is a fundamental concept in object-oriented programming. It refers to the bundling of data, and the methods that operate on this data, into a single unit known as an object.
-
In the context of object-oriented databases, encapsulation ensures that the object's data can only be accessed and modified through the methods of its class. This means that the data is hidden from the outside world and can only be manipulated in ways that are defined by the object itself.
-
This is different from storing objects in a flat file system, using foreign keys to link tables, or normalizing objects into tables. These are techniques used in other types of databases, but they do not involve the integration of data with methods, which is the key aspect of encapsulation.
-
Therefore, the best definition of the principle of encapsulation in object-oriented databases is "The integration of data with methods that operate on that data".
