patterns
2/5
The correct answer is (C) data mining. The reasons for why data
mining
is the correct answer and the other answers are incorrect are
described
as follows:
a. Sequential processing: Sequential processing is a term used
to
describe the processing that occurs in the order that it is
received. It
processes items in a collection of data according to some
specified
sequence of keys, in contrast to serial processing.
So, this occurs when data or instructions processed
sequentially, in the
same order as they are accessed. It doesnt search for
identifiablepatterns of data. That is why answer number a is
incorrect.
b. data warehousing: A data warehouse (DW) is a database used
for
reporting. The data is uploaded from the operational systems
for
reporting. The data may pass through an operational data store
for
additional operations before it is used in the DW for
reporting.
This definition of the data warehouse focuses on data storage.
The mainsource of the data is cleaned, transformed, catalogued and
made
available for use by managers and other business professionals
for data
mining, online analytical processing etc. The main purpose of
data
warehousing is storing data, not searching. So, this answer is
incorrect
too.

d. real-time processing: Data processing that appears to take
place, or
actually takes place, instantaneously upon data entry or receipt
of a
command. In a real time processing, there is a continual input,
process
and output of data. Data has to be processed in a small
stipulated time
period (real time), otherwise it will create problems for the
system. Forexample: assembly line robots and radar system, ATM
machine, online
chatting.
Real-time processing processes data instantly, it doesnt spend
much
time in finding identifiable data patterns. So this answer
should be
incorrect too.
c. data mining: Data Mining is the process of searching data
within the
data warehouse for identifiable patterns that can be used to
predict
future behavior. Data processing using sophisticated data
search
capabilities and statistical algorithms to discover patterns
and
correlations in large pre-existing databases; a way to discover
new
meaning in data.
Data mining is the process in which there is analysis of data
form
different angle and perspectives and summarizing the same data
into the

relevant information. This kind of information could be utilized
to increase
the revenue, cutting the costs or both.
So, data mining searches for identifiable patterns of data to
organize,
prepare and process them. According to the question- the process
of
searching identifiable patterns of data is called-, the correct
answer willbe (C) Data mining.
