Preface
This work for an android application for the requirements of Software Engineering course project
in Computer Engineering department at The Islamic University of Gaza. This work provides the
scope and context of the project to be undertaken. It details the intended user group and the value
that the system will have to them. It also provides a schedule for the completion of the project,
including a list of all the deliverables required.
1. Introduction
a. Purpose
This document contains the complete design description of the android application “Money
manager”. This includes the architectural features of the system down through details of what
operations each code module will perform and the database layout. It also shows how the use
cases detailed in the SRS will be implemented in the system using this design.
The primary audiences of this document are the software developers.
b. Scope of project
This software system will be an android application “Money manager”, where the objective from
it is to design a sophisticated system which will help in planning, monitoring, and controlling the
finances of your own, project or organization. This system will be help the users to plan budget
more efficiently . Rather than getting to keep track of everything throughout the month, the
Money manager lets you create custom categories in which you can simply subtract from as you
spend. Just add your expenses to different categories and this app will tell you when you are
running low on cash. Money manager helps plan and monitor your budget to determine wasteful
expenses, Quickly adapts to changing your financial situation and achieving your financial goals.
One can use this Planning process to prioritize your spending and focus your money on things
that are most important to you.

sub-categories such as gas and electricity), food, entertainment, and so on , and other expenses,
such as those outside the home, you have the option not only to enter and classify Them in a
variety of ways.
Money manager is a handy mobile tool for managing finance. This application is suitable for

solution for managing your finances. you can organize cash flow, expenses and bank accounts in
one place. Easy to understand graphs and graphs let you visualize how you spend your money
from month to month.

c. Glossary:
Architectural
design
is concerned with understanding how a software system should
be organized and designing the overall structure of that system.
confirmation
the action of confirming something or the state of being confirmed.
attributes
a quality or feature regarded as a characteristic or inherent part of
someone or something.
Collaborate
work jointly on an activity, especially to produce or create
something
Emphasis
special importance, value, or prominence given to something.
Use cases
a model of UML diagram that shows the interaction between a
system and its environment

 1.5. Overview of Document :
 Chapter 2 is a Deployment Diagram that shows the physical nodes on which the system
resides. This allows a clear explanation of where each design entity will reside. No design
unit may straddle two nodes but must have components on each, which collaborate to
accomplish the service.
 Chapter 3 is the Architectural Design. This is the heart of the document. It specifies the
design entities that collaborate to perform the functionality of the system. Each of these
entities has an Abstract Specification and an Interface that expresses the services that it
provides to the rest of the system. In turn each design entity is expanded into a set of
lower-level design units that collaborate to perform its services.
 Chapter 4 is the basic Data Structure Design, which for this project is a relational
database. While it is separated out here for emphasis, it is really the lowest level of the
Architectural Design.
 Chapter 5 is on User Interface Design and discusses the methodology chosen, why it was
chosen and why it is expected to be effective.
 Chapter 6 describes the structure of the Help System.
 Chapter 7 exhibits the Use Case Realizations. The implementation of each use case
identified in the SRS is shown using the services provided by the design objects.
 Since there are no real time considerations, that chapter has been removed from this
document.

2.0. Deployment Diagram
Usually, you release your application through an application marketplace,
such as Google Play. However, you can also release applications by sending
them directly to users or by letting users download them from your own
website.
The publishing process is typically performed after you finish testing your
application in a debug environment. Also, as a best practice, your
application should meet all of your release criteria for functionality,
performance, and stability before you begin the publishing process

0.5 User Interface Design :
In the (Money Manager) App When the user opens the program for the
first time an interface will appear to enter the user name and password
and then show him the main interface of the application.
when he presses the plus button he can add the value of the total
balance that he wants to enter.
When he presses the minus button, he selects the specific category and
enters the amount of expenses.
When you click on the category icon, a list of the actual categories will
appears.
User can modify the amount of expenses or delete the category entirely.
also in this list we have an option that allow the user to add a new
category with selected icon the user can choose it and enter the earn
value of this category.
When he add a new category it will appear in the main screen .
Every category appear at the main screen with its percentage (the
expenses from the total earn of it).
in the main screen we have a circle , inside this circle the total spend
will write .
The pressing on the three vertical dotes will show the setting list, in that
list the user can requests a report of all the details (total balance ,total
expenses, all categories and its spends ) .
Also in the setting list the user can select the mode of the period that
needed to spend the money on it ,the period mode can be a month or a
semester.
Another option here is the help option it allow the user to ask for help
or more details.

6.0 Help System Design
 There is only a minimal Help System for this project.
 The setting will have a Help choice that will contain the following
information:
1.An overview of the applications functionalities extracted from
the SRS.
2.A list of error messages and details on why they were generated.
3.The Help System will contain instructions on how the user can
bypass the user interface and access the database directly and
how to use this app.
