3. IN A NUTSHELL, WHAT DO I GET
PAID FOR?
Analyze the data generated from National Fire
Incident Reporting System from the past 15
years.
Firing queries in Sequential Query Language
Generating easy-to-read graphs from derived
results
Sitting in front of a computer for hours
4. Asking the big question:
WHAT IS NFIRS?
The National Fire Incident Reporting System
is an information system initiated and
supported by the U.S. Fire Administration.
They developed NFIRS as means of
assessing the nature and scope of the fire
problem in the U.S.
5. NFIRS in numbers
Year started
Fire departments
participating
Number of well
years documented
Number of modules
for each year
Number of incidents
per year

9. FUN FACTS ABOUT DATA SIZE
Harry Potter
Number of words per book:
The Philosopher's Stone - 76,944
The Chamber of Secrets - 85,141
The Prisoner of Azkaban - 107,253
The Goblet of Fire - 190,637
The Order of the Phoenix - 257,045
The Half-Blood Prince - 168,923
The Deathly Hallows - Approximately
198,227
Each of these books range from 2
MB to 3 MB
NFRIS
Basic Incident Table 2 Million records
Fire Incident Table 600,000 records
Incident address Table 2 Million
The above mentioned files are of 150
MB- 300 MB each.
For the years 2000- 2014 total size:
1.60 GB * 15 years = 24 GB
5 Million * 15 years = 75 Million
records
All the above calculations are based on approximate values

12. DATA CLEANSING
The process made sure we had the right set of
data at our disposal with minimum variance
and abnormalities.
It was mostly performed on known set of
variables. For instance there are 50 states,
although the in the data there 58 states
abbreviated as 0, 5, 8 or any random number
for that matter. These are the anomalies which
need to be filtered out.
13. FIRING QUERIES:
In layman’s term:
Number of fire incidents which took place in the
United States for the past 15 years where the
Automatic Extinguishing System failed.
14. SELECT COUNT(DISTINCT INC_NO) AS NUMBER_OF_INCIDENTS, STATE FROM(
SELECT INC_NO, to_date(to_char(INC_DATE,'09099999'),'MM/DD/YYYY') as
IncidentDate, STATE, FDID, AES_OPER
FROM FIREINCIDENT2010
WHERE
STRUC_TYPE='1'
AND BLDG_ABOVE >'0'
AND STRUC_STAT= '2'
AND AES_PRES ='1' OR AES_PRES ='2' --Present AND Partial System Present
GROUP BY INC_NO, to_date(to_char(INC_DATE,'09099999'),'MM/DD/YYYY'),
state, FDID,AES_OPER
ORDER BY to_date(to_char(INC_DATE,'09099999'),'MM/DD/YYYY') ASC
)
WHERE
AES_OPER ='2' OR- -AES Partially worked
AES_OPER ='4' OR—AES failed
AES_OPER ='0' OR
AES_OPER ='U'
group by STATE
ORDER BY STATE;
