insert, delete, update data in database

hi. i'm trying to create a c# application which would insert, update and delete data from a database. could anyone pls point me to the right direction in which i should take? thanks in advance.

You are talking about a Compact Framework application that leverages SQL Mobile for on-device data persistence. To get started with these technologies, start here: http://msdn.microsoft.com/mobility/gettingstarted/default.aspx

You can also download the IBuySpyStore sample application from GotDotNet, which is a complete example of a CF2 application working with SQL Mobile.
