Explain your role as a system analyst in context of the system you
designed in first assignment. Explain how did you use the OO approach
in designing the system and clarify the benefits of using the relevant
UML diagrams in your design. Remember to address the advantages
and disadvantage of OO paradigm and give examples as appropriate
and cite your work properly. (500 words)Ans : System Analyast comes up with responsibilities like implementing
system, designing and analysis of the system so that it can meet the need of
organization. System Analyst aim to play a key role in having operational
management of information system(Fortino
et al. 2015). The overall role of
system analyst aim to change with time. System analyst aims to huge number
of changes for providing value to the organization. In the first assignment,
QAHE university has come up new liabrary system for their staff and student.
The university wants to built a digital management system which will allow its
members to use the whole thing in easy and efficient way. In this system,
admin can easily keep a track of records of different stocks in the liabrary. In
this system, it has beocme possible to search and new kind of items in stock.
There is a psossibility of recording items that have been lost and their
replacement. All the user can serach for the required items but they need to
login to system before reserve item (Dou
et al. 2015). The system has been
designed in such a way that student can reserve 3 items and borrow around 5
items while the staff can reserve upto 5 items and can borrow upto 10 items.
In OO apprach, the major focus is all about collecting both strcuture
and behviour of the system into small modules. It is mainly done so that they
can easily combine both process and data. The main notion of this approach is
all about enhancing qulaity and overall productivity of the system (Fan
et al.
2016). This is mainly done in system design and analysis which makes it very
much usable in nature. In the analysis stage, OO is taken into picture for filling
up gap in between the issues and possible solution. This is mainly performed in
certain situation where system focus on continuous design, maintennace and
its overall adaption. It is generally done for identfiying different objects in the
whole problem domain (Valente
et al. 2017). This is mainly used for classifying
both data and behaviour. OO model can bring huge number of benefits like
 It focus on certain number of chnages in system that are avaialble at
low cost.
 It emphasizes on complete reuse of available components.
 It helps in simplifying the issues of integration of components that is
needed for configuring system.
 It merely help in proper design of the given system.
There are large number of benefits of using UML diagram in the design like
Widely-Used and Flexible : UML is a well –known platform that is used in
software design. It is knonw to be as a well known standard that is used among
developers.
Software architecture needs to be communicted efficiently : Software
architecture can be stated like a blueprint of the system. This can be stated as
a framework on which the overall efficiency of the given system depends (Dou
et al. 2015). This framework is effective in nature if and only if it communicate
efficiently. This is the place where unified modeling Language (UML) comes
into picture.
There are various benefits of OO approach like
