I need to build the following:
I have five mobile phones in a country where there is a single monopoly telephone company. SMS services are currently available in the country in question.
I have a PC with a simple database. I want to connect one of the phones to this PC so it will act as a server to the four remaining phones(clients). From the four client phones, I want to send a simple query like a customer #, and get back about 5 lines of information from the server, like name and address of the customer queried.
Please guide me in building this simple client server application and implement it on the architecture and available communication platform described within the first paragraph.
