Body
The main key is to make sure your game logic is not affected by your threading model. As such, most game servers look something like this: <pre><code>main() { gGlobalReadOnlyStuff = LoadReadOnlyStuff(); SpawnThreads(numCores); // could be another limiting resource... WaitForThreadsToBeReadyToGo(); while(1) { WaitForNetworkInput(networkInput); switch(networkInput.msg) { case ADMIN_THING: // start/stop websever, dump logs, whatever... DoAdminThing(networkInput.params); break; case SPAWN_GAME: // replace 'game' with 'zone' or 'instance' as needed idThread = ChooseBestThread(); // round robin, random, etc PostStartGameMessageToThread(idThread, networkInput.msg); break; // ... } } } void ThreadUpdate() { threadLocalStuff = LoadThreadLocalStuff(); SignalThreadIsReadyToGo(); while(1) { lock(myThreadsMessageQueue); // copy messages to keep lock short localMessageQueue = threadsMessageQueue; unlock(myThreadsMessageQueue); foreach(message in localMessageQueue) { switch(message.msg) { case SPAWN_GAME: threadLocalStuff.games.MakeNewGame(message.params)); break; case ADMIN_THING__LET_EVERYONE_KNOW_ABOUT_SERVER_RESET: ...; break; // etc... } } foreach(game in threadLocalStuff.games) { game.Update(); // game will handle its own network communication } } </code></pre> The two hard things then are 'coming up with a partition (game, zone, instance, whatever) appropriate for you game' and 'transitioning things (players, fireballs, epic lootz) across those boundaries' One typical answer is "serialize it through a database", but you could use sockets/messages/files/whatever. But yeah, where and how to make these partitions and minimizing what can go across the boundaries is intimately tied to your game design. (And yes, depending on your setup, there are possibly a few 'shared' systems (logging, memory) that may need a multithreading treatment(or even better, just have one logger/heap per thread))

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.
