AN INTEGRATED MOBILE WEB SOLUTION FOR GAYA HIDUP SEHAT (GHS) TABLOID:
THE IMPLEMENTATION OF WEB SERVICES
Shierly Wiryadi (0700675715)
Abstract
At present, Gaya Hidup Sehat (GHS) tabloid only owns a website that can only be accessed from the computer that is connected to the Internet. The user cannot have anywhere and anytime access to the system. As the solution to this problem, we propose mobile application supported by web services solution as the intermediary application between the mobile and the database.
The web services will be invoked only when it is required; only when the user invokes a process in the mobile application. In developing our application, we implement the Rapid Application Methodology as it the most appropriate with our situation which has limited time and possible to have some changes of scope during the creation of the application. The technique involved in developing this system contains several steps. First, we analyze what services are required by the mobile application, followed by identifying the functionality or operations of each the services, and what they provides. Then, we develop the application using ASP.NET and supported with MySQL server to manage database.
In conclusion, an integrated mobile web solution is a better approach for the GHS current system and it is also expected that the GHS system will be more enhanced and widely used in the future.

PREFACE
We would like to gratitude all parties who have helped us so that we can finish this thesis on time and within scope. This thesis creates an integrated mobile web solution for the Gaya Hidup Sehat (GHS) tabloid. Furthermore, this thesis is created as a mandatory in order to be able to graduate from Bina Nusantara University and to gain Sarjana Komputer degree majoring in Computer Science.
The objective of the thesis is to apply what we have learned during our study in Bina Nusantara University. We also would like to thank to several persons who have, directly or indirectly, help us to finish this thesis:
1. Mr Tri Asih Budiono, MIT, our supervisor, who gives us with the idea about how to finish this thesis in a good way and give feedback and opinion regarding our thesis. 2. Mr Raymondus Kosala, Phd, our co-supervisor, who also helps us in solving the problems we face within development period and giving useful ideas.
3. Mr. Puri, the IT manager of GHS, who allows us to create this thesis within GHS and always gives opinion and requirements within development phase.
4. Friends, who helped us directly or indirectly throughout this thesis
In conclusion, we hope that our thesis could be an example of development in information technology as the implementation of what we have studied in this campus.
