Business Intelligence
It is common knowledge that in today's business environment, organizations must continually strive to achieve a competitive advantage. Likewise, they are reliant on large amounts of data to make their business decisions.From the e-Activity, explain the key way(s) in which your selected organization / agency uses business intelligence in order to gain a competitive advantage. Next, speculate on the technological limitations regarding data, software, and hardware that you believe might challenge your chosen organization / agency in the future. Provide a rationale for your response

METARs are reports assembled with a particular format that is easy to decode with computer systems using regular expressions
METARs are reports assembled with a
particular format that is easy to decode with computer systems using regular
expressions.
These reports typically come in two
forms: North American METARs and International METARs. Create a series of regular expressions that
decode each token of information using the North American METAR form.Please see files and Example.#!/bin/bash
printf
"Report type: "
egrep -o
'METAR|SPECI' metar.txt
printf
"Station: "
egrep -o
'\sK[A-Z]{3}\s' metar.txt
day_of_month=$((
$(cat metar.txt | cut -c12-13) ))
metar_time=$((
$(cat metar.txt | cut -c14-17) ))
printf "Day
of the month: %d\n" $day_of_month
printf
"Time: %d Zulu\n"
$metar_time

1) read string,
but if using math expansion, cut only digits
2) egrep
(extended grep) with -o option returns only matched string (watch spaces with
cut)
3) Add if/else
logic to print correct message or no message if missing, or with optional

4) Add
"Cloud cover" all categories
5) Add check and

Research Paper: Business Process Redesign
If you have been involved with a company doing a redesign of business processes, discuss what went right during the redesign and what went wrong from your perspective. Additionally, provide a discussion on what could have been done better to minimize the risk of failure. If you have not yet been involved with a business process redesign, research a company that has recently completed one and discuss what went wrong, what went right, and how the company could have done a better job minimizing the risk of failure.
