    <p>I'm thinking about writing a game which is based around a server, and several client programs connect to it. The game (very) basically consists of a list of items which a user can 'accept', which would remove it from the list on all connected computers (this needs to update very quickly).</p> <p>I'm thinking about using a Java applet for the client since I would like this to be portable and run from a browser (mostly in Windows), as well as updating fast, and either a C++ or Java server running on Linux (currently just a home server, but possibly to go on a VPS).</p> <p>A previous 'incarnation' of this game ran in a browser, and used PHP+mySQL for the backend, but this swamped the server quite a bit when several people connected (that was with about 8 people, this would eventually need to handle a lot more).<br> The users would probably all be in the same physical location (with the same public IP address), and the system would get several requests per second, all of which would require sending the list back to the clients.</p> <p>Some computers may have firewall restrictions on them, so would you recommend using HTTP traffic, a custom port, or perhaps through SSH or some existing protocol?</p> <p>Could anyone suggest some tips (threading, multiple requests of one item?), tools, databases (mySQL?), or APIs which would help me get started on this project? I would prefer C++ for the backend as it would be faster, but using Java would allow me to reuse code.</p> <p>Thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
