I need three steps of the same project:
1 - TCP data server, in Java or C, to receive data from external access, with large access capacity (like as 200 same time each port)
2 - database (SQL) to save the data received by server
3 - PHP interface to show the data to user. The data is GPS coordenate, so need to show in google maps. The PHP interface need to have options to register each product that will send GPS data, show current and historic position, and select the products that want to show (filters).
