I've written a credit card applicatoin that's accustomed to manage tasks. Much like tasks management in MS Outlook. I must store data of those tasks in certain kind of database, but have no clue where must i start.

This database need to be baked into my application and really should be saved in single file. I believed about something such as Outlooks PST file.

Any guidance appreciated.

Unsure what the application is designed in however i would take a look at SQLite (http://www.sqlite.org/).
