Designing and developing routines required for communication with central server of German Golf Association (DGV) from Golf Software of different vendors. This project included development of client side routines for managing incoming/outgoing data (validating, pre/post data processing, error handling and so on). Server side scripts were designed for processing clients' requests (authorization, preparing data, uploading/download data from/to clients). The data is being transferred between client and server in a packed form (ZIP packing) allowing to improve performance and reduce traffic.
