Abstract

Dental Clinic XYZ is a clinic that gives service for prevention and/or treatment (surgical or

  nonsurgical) of disease in oral cavity. The clinic is located in Kuningan. For dental equipments, this Clinic is using latest technology. But some of the business processes in this Clinic are still using paper base and manual input, like scheduling and appointment, transaction and patients’ data. Besides that, the parking area in that clinic only gives 4 parking spaces for cars. Those conditions make the clinic can’t give its best services to the patients.

  

This thesis writing is aimed to analyze the current system in Dental Clinic XYZ, and overcome

all problems found in the current system. Furthermore, proposed new application to help the

clinic in developing computerized system for patient database in order to simplify their business

process, and minimize human errors.

  

The proposed system is designed based on the analysis of the current system. It is aimed to put

all patient data in a database and integrate business processes into single application. The

information system that are covered include Patient database, Transaction Management, and

User Account Management.

  

The proposed system is expected to help the doctors, nurses, and administrator of Dental Clinic

  

XYZ in order to increase the effectiveness, efficiency, and customer satisfaction through

automation of business process.

  Keywords: Information System,, Database System, Transaction Management.
