A multidimensional database (MDDB) is a type of database in which data can be viewed from multiple dimensions; commonly used with <u>MOLAP</u>.
A multidimensional database affords the ability to swiftly procedure statistics and generates solutions quickly. MDBs let users ask questions about corporations' operations and traits.
The multidimensional databases make use of MOLAP (multidimensional online analytical processing) to get admission to its statistics. They permit the users to fast get answers to their requests by means of generating and analyzing the records as a substitute quickly. The information in multidimensional databases is stored in a records dice format.
In a dimensional database, you have rows and columns, represented by means of X and Y. In a multidimensional database, you have got X, Y, Z, etc. depending on the number of dimensions in your statistics. Beneath is an instance of a 3-Dimensional statistics Array represented in a relational table and in 3-D.

Answer:
Energy cannot be changed from one form to another without a loss of usable energy
Explanation:
Second law of thermodynamics states that the total entropy or the randomness of the system remains constant over time. It also states that the net entropy will remain the same or it will increase.
Entropy of a system is given by heat absorbed divided by temperature. It is given by :
So, the correct option is (A) "Energy cannot be changed from one form to another without a loss of usable energy".
