Question

Match the following :

$\begin{array}{clcl}  \text{(i)} & \text{OLAP} & \text{(a)} & \text{Regression} \\ \text{(ii)} & \text{OLTP} & \text{(b)} & \text{Data Warehouse} \\ \text{(iii)} & \text{Decision tree} & \text{(c)} & \text{RDBMS} \\ \text{(iv)} & \text{Neural Network} & \text{(d)} & \text{Classification} \\ \end{array}$

• A. $\text{(i)-(b), (ii)-(c), (iii)-(a), (iv)-(d) }$
• B. $\text{(i)-(b), (ii)-(c), (iii)-(d), (iv)-(a) }$
• C. $\text{(i)-(c), (ii)-(b), (iii)-(a), (iv)-(d) }$
• D. $\text{(i)-(b), (ii)-(c), (iii)-(d), (iv)-(a) }$

Answer 1

a) will be regression instead of registration

 sometimes used interchangeably, the terms data warehousing and online analytical processing (OLAP) apply to different components of systems often referred to as decision support systems or business intelligence systems.

Decision tree is used for classification of data in data mining and AI

 neural networks are used for the purpose of unsupervised learning,  regression or classification

OLTP   In OLTP database there is detailed and current data, and schema used to store transactional databases is the entity model (usually 3NF).

hence i-b , 2-c , 3-d ,4-a  Ans is B
