Abstract 
 

Jewelry shops deal with different types of people every day. Even they are customers or dealers. 

A lot of calculations are made daily with different currencies (JOD, NIS, USD). That makes the manager 

aware of any loss. But being aware is not enough. 

Actually, even with bills and recording every process have been done some times losses appear. 

So shops like these need an organized system that takes control of all these processes. 

Almodeer almohasabi is a responsive desktop application that helps the managers of jewelry shops 

(specialized for golds) to organize their calculations in a customized manner. Through our application, 

users will not miss anything matter to their benefits. Everything will be stored in an organized database. 

The project provides a simple and easy user experience.

Chapter 1 Introduction 

1.1 Problem Description 
Nowadays, jewelry shops spreaded all over the world. Almost everyone have tried to deal with 

jewelries whether buying or selling them. That makes jewelry shops deal with too many people 

daily with different desires.  

Unfortunately, dealing with this number of people daily causes incorrect calculations. However, 

this problem can be solved by having a service that does all these calculations automatically and 

store all needed information in an organized database. This application helps the manager of the 

jewelry shop to save his time, avoiding loss, organizing all different bills, and moreover.  

Based on all of that, we came up with the idea of building a desktop application (Almodeer 

almohasabi) that solves this problem and facilitates on people dealing with money and gold stuffs. 

1.2 Objectives 
The main objective of our project is to build a user friendly, desktop-responsive application that 

serves as an organizer and helper at the same time. In which users are started using this application 

to help them with their work. 

1.3 Scope of work 
This application prompts only for jewelry shops (specialized for golds). Users just need to enter 

basic information in order to make this application works regarding on it. 

1.4 Glossary 

 

 

 

C# Simple, modern, general-purpose, object-
oriented programming language developed by 
Microsoft. 

Database Is an organized collection of data, generally 
stored and accessed electronically from a 
computer system. Where databases are 
more complex they are often developed 

using formal modeling techniques. 

Sqlserver 2014 Is a powerful and reliable free data 
management system that delivers a rich and 
reliable data store for lightweight Web Sites 
and desktop applications.

1.5 Importance 
With the variety in the types of jewelry, it would be hard for each of us to be acquaintance with 

all of these types. So and on the other hand, it would be more helpful for the owners of these shops 

to have a system that organizes all the work in sufficient database. As a result, the owner will have 

no loss and keep all his data stored in an organized way. 

1.6 Organization of the documentation 
The report is organized in six chapters. In chapter 1, we introduce our project briefly. In chapter 

2, we describe the constraints we faced before and during the development process, standard we 

followed and courses that helped us in the project. In chapter 3, we discuss the language and IDE 

that we used and the most helpful included features. In chapter 4, we describe our methodology 

and the development of all parts of our project. In chapter 5, we discuss the results we achieved. 

Finally the project Conclusion, recommendations and future work in chapter 6. 

Chapter 2 Overall Description 

2.1 Product perspective: 
An accounting program that deals with selling and buying operations according to rules 

pertaining to gold, in addition to storages and terms of use: 

 Products information: 

o  It includes all information about product properties. 

 Customers and supplier information: 

o It includes all information about customer and supplier. 

 Bills information: 

o It includes all information about sales and purchases bills. 

 Vouchers information: 

o It includes all information about receipt, journal and payment vouchers. 

 User information: 

o It includes about information about users (username, password, accounts and 

terms of use). 

2.2 Constraints: 

2.2.1 Time: 
Learning new programing language such as C# and how to deal with DevExpress 

components [1] to the user interface.  

2.2.2 Resources: 
Choosing the best and the right DevExpress components to create a friendly user 

interface. We chose DevExpress components because its features are suitable for our 

application and easy to learn. 



10 
 

2.3 Standards: 
 C# is the fundamental source code of our application, DevExpress components for the 

user interface and sqlserver 2014 for database. 

2.4 Earlier Coursework: 
 During our studies at the computer science department, we have taken some classes 

that helped us in the development of this project: 

 The Database course: this course was necessary to build the database, storage 

system and relations in our project. 

 The C++ courses: it was the main course that we utilized. It include basics of 

handling with C# language that we used in the development of the project. 

 

2.5 use cases: 
 The user will be able to do multi usings we will shown these uses in the following diagram. 

 

 

 
 

Figure 1-use cases 



11 
 

Chapter 3 Literature Review 
 There are several accounting program in local region that offer services for accounting and 

management. These programs are dealing with several sectors like Industrial, commercial, hospitals, 

etc. However, these applications do not focus on jewelry shops especially gold shops. 

 Therefore, our application focuses on jewelry shops (specialized for gold). Almodeer almohasabi 

is designed to be a handler for all accounting and calculation stuffs in these shops. Flexibility and friendly 

use are some of features that Almodeer almohasabi characterizes, where users can deal with it without 

high experience on computers. 

 

Chapter 4 Methodology 

4.1 Technical Choices 

4.1.1 C# programing language 
  What is c#? 

C# is a hybrid of C and C++, it is a Microsoft programming language developed to compete with 

Sun's Java language. C# is an object-oriented programming language used with XML-based Web 

services on the .NET platform and designed for improving productivity in the development of 

Web applications. [2] 

Why C#? 

C# has several features that make it a great choice as a source code for developing applications. 

These are some features that we benefit from mostly in our application: 

 C# is a simple, modern, object oriented language derived from C++ and Java. 

 The classes and data types are common to all of the .NET languages.  

 .NET includes a Common Execution engine and a rich class library. 

 In C#, Microsoft has taken care of C++ problems, such as Memory management, 

pointers etc.  

 It supports garbage collection, automatic memory management, and a lot. 

4.1.2 DevExpress components 
  What is DevExpress components? 

DevExpress is a custom third party provider of .NET controls. They customize the .NET controls 

by making it more attractive and more flexible than inbuilt .NET controls. 

 Why DevExpress? 



12 
 

The most important reasons are the flexibility and easy to use while developing applications. 

4.1.3 Sqlserver 2014 
 

  What is Sqlserver? 

Microsoft SQL Server is a relational database management system developed by Microsoft. 

As a database server, it is a software product with the primary function of storing and 

retrieving data as requested by other software applications—which may run either on the 

same computer or on another computer across a network (including the Internet). 

 Why Sqlserver? [3] 

There are many advantages helped us to choose the sqlserver : 

1. Lower Cost Of Ownership: there are express edition of sqlserver it’s 

free. 

2. Security Features Are Better: SQL Server uses Policy-Based 

Management to detect security policies that are non-compliant. 

This feature allows only authorized personnel access to the 

database. Security audits and events can be written automatically to 

log files. 

3. Installation Is Streamlined: It can be installed via a setup wizard and 

the prerequisite updates are detected and downloaded by the 

installer automatically. 

4.2 Experimental Methods 

4.2.1 Database 
When we built the database we tried to follow all basics we learned it in the database 

and advanced database courses we studied. In this section we will show the diagram of 

database exported using sqlserver and the technique we used to do queries (insert, 

update, select and delete).

Chapter 5 Results and Discussion 
 In order to prove the results of our project, we present the following test scenarios of the 

various activities on the application: 

 Checking the currencies, constant and screen price 

All jewelry shops work depends mainly on the currencies and its exchange rate. So we checks everything 

the user might forget or enter incorrect input.

Chapter 6 Conclusion and Recommendation 
 In this project, we built an application that aims at organizing various processes in one place, in 

order to make it easier for user to be acquaintance of all these processes. This will benefit the owners of 

jewelry shops to not be afraid of any loss. 

 From this project, we gained an experience in C#, which is considered a new programming 

language for us.  

 One of the most achieved works is being familiar of DevExpress component to obtain a friendly 

user desktop application. We also improve our search skills, since we faced several problem that needs 

to solve.
