- which offer description has least and more times occurred
- which offer number has least and most occurrence
- which offer type has least and more occurrences
- which partpin has least and more occurrences
- which offerpin has least and most occurrences
- what is the highest and what is the lowest cost. Are they repeated? if so how many times and for
what offer types they repeated
- List down the top 10 offer descriptions
- List down the top 10 offer types
- Which offer description has highest price and which one is lowest price
- What is the difference between the highest price and lowest price
- How many offers are released in each year
- for the customer which Part pin you will suggest - At least suggest 3 categories
- For the customer which Offer pin you will not suggest - you should not suggest 3 categories
- for how many records its under loss
- For the combination top offer description and the top offer code how many Part pins are repeated
- Country code has how many Offer numbers
- For each year prepare a tab separated file as below
year maxopencost maxclosecost offernumber offercode country
Zone wide
- All the above mentioned should be repeated for the entire zone
- zone has how many country codes
Total
- All the above should be repeated for the entire zone
- Total how many country codes are there and each zone has how many country codes. Come out
with a CSV formatted file output
Ex: zone1,AM,300
zone1,AT,365
Different Zones
- from each zone which country has more machine types
- from each zone which country has highest price and give the complete details.
- In the zone what is the highest price and give the complete details

Project #3 : DWP CIS (Customer Information System)
Client : Public Sector, UK Government, Preston, UK
Environment : Core Java, J2ee, JSP, Struts, Web services, Altova XML Spy, WAS 6.0, RAD,
Apache ANT, Oracle SQL Developer, RTC 3.0
RDBMS : Oracle
Duration : 19 Months (Nov’ 11 – May’ 13)
Description : CIS is Customer Information system which holds all the personal details of
the UK Citizens. Along with the personal details that they are entitled for and registered are also
stored in CIS.CIS is primary for the personal and slave for the benefits and award details stored in the
database.
CIS was formed in 2004 by merging two systems (DCI and PDCS). DCI is Department Central Index
and PDCS is Personal Data Computer Store. These two were two different systems altogether and
they never used to communicate to each other.
Because of that whenever the change is happening in one system, the same was not getting
reflected in the other system. As part of Release 1, CIS database was built by having the information
to flow from DCI and PDCS to CIS.PDCS was COBOL based and all systems which were talking to PDCS
started to talk to CIS now through batch and online. Dialogues were replaced by SEF screens and
functions. This will mean that the mainframe dialogues will be replaced by browser based screens.
The CIS online Functions which will provide as replacement for DCI can be decomposed into number
of discrete function types like Primary access, Secondary access, Data link Requests and Inter Service
Access.
