Which of the following is the marriage of object-oriented and relational technologies combining the attributes of
both?

A.
object-relational database

B.
object-oriented database

C.
object-linking database

D.
object-management database

Explanation:
An object-relational database is described as is the marriage of object-oriented and relational technologies
combining the attributes of both.
An object-relational database (ORD) or object-relational database management system (ORDBMS) is a
relational database with a software front end that is written in an object-oriented programming language. A
relational database just holds data in static two-dimensional tables. When the data are accessed, some type of
processing needs to be carried out on it—otherwise, there is really no reason to obtain the data. If we have a
front end that provides the procedures (methods) that can be carried out on the data, then each and every
application that accesses this database does not need to have the necessary procedures. This means that
each and every application does not need to contain the procedures necessary to gain what it really wants from
this database.
Incorrect Answers:
B: An object-oriented database is a database designed to handle a variety of data types (images, audio,
documents, video). This is not what is described in the question.
C: An object-linking database is not a valid database type.
D: An object-management database is not a valid database type.
