Database Question. Don't want to use localhost or hosting, anyother option?

Hi, i have just started learning database. But what i m learning is executing queries through localhost, or any hosting. for that my client has to install wamp/xamp etc.

Is there anyway else, like having a database in the same folder. and with only one .exe file it stores data in it etc.??

I'm not sure I understand what you want. You want a database that's not being hosted by your local client machine and also not being hosted by a network machine? Such a system exists since a database has to be somewhere, either on your machine or elsewhere.

.exe files shouldn't be used to store application/database data. They are used to store data and instructions for how the application should work, but the user data should be found elsewhere.

If you want data to be shared across instances, you're best bet is having a centralized database and/or application server. If you do not need to share between instances, look at using an embedded database, Apache Derby being the first that comes to mind.
