dental hospital appointment system for software engineering course

1. INTRODUCTION

The purpose of this document to give a general information about the project

and emphasizes the important parts that interacts with the main system.

This report will be read by the manager of the dental hospital and board of

management. This report will provide managers to see the interaction between dentists

and the patients as well as the information they will share. Project will help the dental

hospital to reach their potential patients.

While preparing the Project, firstly, the requirements were considered and

design of the Project was completed. In the design part, all the operations were shown

step by step. After the completion of the design, the code of the Project was written

and implementation part was carried out.

2. CORPORATE OVERVIEW

This system provides patients to see the information and the schedule of the

dentists in order to choose their own dentist for any operation. Also, in the system,

both patients and the dentists can see the former operations, that had been done to the

patients, on the reports which are prepared by the dentists.

3. SYSTEM REQUEST

Project Sponsor: Mehmet Sapmaz, Manager of the Dental Hospital

Business Need: This project has been initiated to reach new patients via Internet, to

increase the potential of preferability and to provide an effective way to monitor the existing

patients.

Business Requirements: Using the web, patients should be able to register to the

system, list dentists and reach their schedules, select their own dentists, update or delete their

own appointments. They should be able to search a specific dentist or time to get an

appointment. if they choose a dentist that is very busy, the system reserves its rights to assign

the patient to another dentist. Dentists should be able to upload their schedules, update or

delete appointments. They should also be able to list and reach all information of their own

patients. Finally, admin(s) should be able to add dentists with their information, update or

1

delete them. The admin(s) should be able to list all dentists and patients and reach their

information.

System will assign patients automatically one by one to the dentists if they do not

choose a specific dentist. Therefore, equal distribution of the patients will be provided by the

system.

The functionality that the system will have is as follows:

- Capture patients information.

- Keep the dental processes made to patients.

- Produce dental control reports to patients.

- Show the available times of dentists.

- Provide information about dentists.

- Search for a dentist by a patient.

- An appointment is possible to be gotten both manually or automatically.

Business Value: We expect that Hospidental will increase the average number of

patients that come to the hospital in a year. In this way, annual earning will increase about

%20 per year. We also expect via the online appointment system, patient complaints will

decrease because more than %40 of the all patients reproach from hardship of getting an

appointment at any time they want.

Conservative estimates of tangible value to the hospital include:

- $240,000 (%20 of $1,200,000) from new customers.

- $400,000 (%20 of $2,000,000) from existing customers.

Special Issues or Constraints:

- In the future, the appointments may want to be gotten only online.

- The system should be completed before the end of May 2012.
