Scenario

Asia Pacific Tourism Association– APTA (http://apta.asia/)would like organize a series of conferences focusing on research topics in the area of travel and tourism. As a part of their operation, they need to organize annual conferences for researchers and industry practitioners to meet and present their work in 2018. You are appointed as an analyst programmer to develop a system to support the conference organization of APTA.

Your task is to investigate the operation of APTA and identify potential events or conferences through the provided link or any other resources available online. You will design and develop a conference management system for APTA that allows conference organizers to manage the events and registrations. The system should store conference/event details, organizers details for each conference, attendee details and their event registration. 

Model Design Requirements

You are going to design a model to store data for your application with the following specification:

? You have freedom to design your own data architecture and properties for the classes, however it should reflect your understanding about complex entity relationships, including one-to-one, one-to-many, many-to-many, and inheritance.

? The application should store information for every class and relationship. Inheritance should be used to model classes with similar properties. For example, human being class may have common properties such as ID, Name, Contact details (email, phone, address, etc...). Besides, each unique class should also have its own properties. You should provide justification in your report, on the proposed classes, properties and their relationships stating why they are necessary.

? Appropriate data annotations and input validations should be provided in all model classes. You should customize your own error messages and NOT use the default error messages provided by the template. 

An example model is provided in Sample Document.pdf file (VU collaborate), to help you better understand how the application should be implemented. However, you must NOT use the provided model, as it is not suitable specifically for the case in this assignment
