1. Right I have created a local database and remotes Databae, which implement the same interface for switching, and they both are stored at server site. Local database whose update() method don�t consider lock/unlock, whereas remote database needs. I am wondering if I need two copies of client programs (e.g. GUI's for local and remote modes): one copy at client for remote access to database and other copy at server for local access to database. When I run the local mode I will start the system at the server side. When I run the system in remote mode I will have to run at the client side. 2. I am using socket to do this assignment. There are only two tasks: search and book. I am wondering if one task (search) has finished, I need close socket. When another task starts (book), I open a socket and then close. Am I right? Thank you Chaohua
"they both are stored at server site" In local mode there is no server. So in local mode it does not start on the server. It always starts on client, and in local mode that is all there is no Sockets, no server. Mark
