Hi all, Although I am not 100% sure this is the right forum category, I have a question about the choice of database. I am currently running an online, webbased, multiplayer RPG, written in PHP and based on a mySQL database. Now, we want to rewrite this game, using a client-server model, writing the client in Java and the server in either Java or C++ (on a Linux server). Since this fits well with the game design, we want to apply rather strict object-oriented programming. Now the question is, what is a good database system to work with? Should we just stick to mySQL, or would it be wiser to switch to an OODBMS? And does anyone have any experience with a free OODBMS (since it is a free game, I cannot afford using a commercial DBMS), like Ozone or anything like that? And in the context of a game, and of a multiuser/multitasking environment, what works well? What kind of things should I keep in mind when making such a choice? I have substantial experience with SQL now, but only read a little bit about OODBMSs and have no experience with it yet. Any comments / ideas would be very welcome.
