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
