6 Read the following case study thoroughly and answer the following questions:

Laxmi bank is one of the largest private sector banks of India. It has an extensive network of

more than 200 branches. It offers banking services to retail as well as corporate clients. The

bank faced a challenge in integrating multi-pronged database management system into a

centralized system. The IT department of the bank also realized that the computing capabilities

of its PCs and servers were not proportionately distributed among all its branches. Each branch

had its database management system stored in a traditional way on the disk. The total cost of

operating and maintaining the current IT infrastructure was very high and the fundamental

shortcomings added to the costs. Moreover, there were also recurrent problems due to the

malfunctioning of the currently operational database management system. Therefore, the

bank’s top management decided to fix the problem and operationalise a robust database

management system. The bank hired an external database technology consulting firm called

AKPY Info systems Limited.

AKPY divided the entire IT infrastructure of the bank around two verticals. The retail banking

vertical and the corporate banking vertical. All the individual database servers from the

individual branches were removed. The entire database system was made virtual such that the

managers and the staff can access only the required information (related to retail banking or

corporate banking) from the respective centralised data centers. There were only two such

centralised data centers (one for retail banking and another for corporate banking) that were

managed centrally. Staff and managers could access the information through their PCs and

laptops. Centralised database management system complemented the security system by

bringing in authentication through a unified ID management server. Managers and officers of

the bank were able to process half a million transactions per month in real time after the new

implementation. There were significant savings in the cost and also in the consumption of

power. Now there were no problems with regard to imbalances in the load across various

network servers. Due to centralised data management, top management could keep an eye on

the functioning of various branches. Hence the cases of fraud and cheating reduced

considerably. The bank managers could also process the loan applications in reduced time

since the customer’s previous records could be accessed at the click of the button and approval

from the higher authorities could be obtained in real time. Moreover the new system also

brought in many applications that helped local managers in the decision making process.

a. List the uses of centralized data management

b. What steps Laxmi bank need to take if it were to change its centralised database

system to a distributed database system in future?

A a. Listing the uses from the from the case

study

b. Explaining about data fragmentation,

replication and allocation techniques

c. Is it possible to replicate the centralised

database management model of the bank

in a manufacturing concern? Give reasons.

3 Empirical software solutions is a small manufacture based company who have a single product

in the public access and security domain. The information system which they possess gives

details pertaining to the presence of individuals at specific locations and also checks and issues

security badges.

The software of the system is connected to specially designed hardware peripherals along with

a well-defined LAN network connection. The system handles several aspects ranging from

computing from database manipulation, peripheral hardware ti image handling. This company

uses both software as well as hardware, and incorporates latest technologies, like networking

and device drivers.

Due to the pressure from customers and the competition, they were in need of a structured

software process. There was no standardized development process. Most of their work was

based on customer requests. Every time a new request from customer came in, more additions

were made to the product. A new version of the software was installed at the customer’s site

when requested by the customer. All the queries related to technical support, modifications

made to the system were handled by the development team. There was no specific design

methodology followed and each developer used his own method of working. Apart from the

user manual, there was no other documentation found held.

Challenges:

Introduction of reuse framework and method into the company

Gain support from the top management for the reuse program, as introduction of reuse

program can affect all parts of the software production process.

Suggestions were made to set up the reuse program along with the associated cost and risk

involved in setting up the reuse program.
