| − | ==Project description==
| |
| − | <span style="background:#E6E6FA ">'''In this project, we have created a GUI Java (Swing) Application for a Zoo Management System:'''</span>
| |
| − | * You can try the application by downloading the Java Jar file from this link: http://perso.sinfronteras.ws/images/0/00/SMSimulator.jar
| |
| − | * You can also see or download the Java Project from our Github repository at: https://github.com/adeloaleman/JavaDesktopApp-ZooManagementSystem
| |
| − | * If you just want to take a look to the Application GUI, [[Zoo Management System#A look at the GUI|here]] we show some images that try to describe the most important features of the application.

| − | <span style="background:#E6E6FA ">'''Our Management System allows users (Zoo Administrators) to manage Animals and Zoo Keepers. Some of the functionalities that have been added to the system are:'''</span>
| |
| − | * Search for Animals:
| |
| − | :: Refine by: Type, Specie, Name, etc.
| |
| − | * Search for Keepers
| |
| − | * Add new animals to the database
| |
| − | * Add new keepers
| |
| − | * Update animals
| |
| − | :: Manage aspects such as Medications, Vaccines, Offsprings, etc
| |
| − | * Update keepers

| |
| − | * '''Design Patters:'''
| |
| − | :* We have implemented a [[Object Orientation with Design Patterns#Model-View-Controller MVC|Model-View-Controller MVC]]
| |
| − | :* To facilitate communication between GUI components we have implemented a [[Object Orientation with Design Patterns#Mediator Pattern|Mediator Pattern]]
| |
| − | * [[Java GUI Programming|GUI Java Swing]]
| |
| − | * [[Object-Oriented Concepts and Constructs#Inheritance|Inheritance]], [[Object-Oriented Concepts and Constructs#Polymorphism|Polymorphism]], [[Object-Oriented Concepts and Constructs#Upcasting - Downcasting|Upcasting - Downcasting]]: These were the most important concepts we have learned and implemented in this project. Because animals are broken down into different types (see example below) we had implemented a class-based inheritance model where <Animal> is the super class. We often had to use Downcasting in order to get access to specific behaviors of a subclass into the Animal hierarchy.
| |
| − | * [[Object-Oriented Concepts and Constructs#Abstraction|Abstraction]]
| |
| − | * [[Object-Oriented Concepts and Constructs#Encapsulation|Encapsulation]]
| |
| − | * [[Object-Oriented Concepts and Constructs#Serialization|Serialization]]: We have implemented data persistence through a file using serialization.

| − | The Zoo has a number of Animals. These Animals are broken down into types: Mammal, Reptile, Avian, Aquatic, Insect. For example:
| |
| − | * Mammal:
| |
| − | :* Avian
| |
| − | ::* Bat
| |
| − | :::* date of birth, date of arrival, fight, gender, ofspring, medication, vaccine, exhibit number

| − | '''Each Animal has a Zoo keeper that looks afer it:'''
| |
| − | *Zoo keepers are only allowed to care for animals if they are qualified to do so.
| |
| − | *A zoo keeper can look afer a max of 3 Animal types for a max of 10 animals.
| |
| − | | |
| − | | |
| − | | |
| − | '''Your system must be run on test data before the Zoo will accept it.
| |
| − | | |
| − | | |
| − | | |
| − | '''You are required to have a data set of at least 100 animals and 40 zoo keepers.'''
