Database entegration or data storage

We are working on a multiplayer game that has a database on the server side. All the weapons (Weapon class type) are stored in the database in server. But in the client side how can I show the player all the weapons. Do I need to create a script that has a weapon list that stores all the weapons? Or should I create a database on the client side too (I don't want to do this)? I came up with a solution like storing all the weapons in a XML file and write a script to read from that file but on the other hand I don't know if the clients can reach the files in the "Resources" folder and change them. (It's not a big problem for security on the server side but I don't want them to change the file). Are there any other solutions??

Thanks..
