portable application recommended for offline use

hi,
we're looking into designing a portable application that contains tables and graphs and pulls data from a database. this application must be portable where we can manually connect to db and update data and graphs then share the application with users. the application must be portable and shared by email and can be used offline.

once option is using flash with action script to connect to our sql server and update data but not sure how easy to create charts or reports since it's not a reporting tool !!!

an access in another one. any recommendations are appreciated.

thanks

Which database (Access? SQL Server? MySQL?) Where will it reside? Can the application be installed on the computer or does it have to run with no installation?

it will be connected to sql server, store the data in some kind of dataset then redistribut to employees with no installation needed.

thank you
