Adding on-line data to sqlLite question

Hello All My Friend,

I am developing an extension which has database and work with SqlLite.

I want to know whether it is possible to insert data online to this
extension.

Maybe it would be better to explain it in this way:

I have a database with some default data on database,I publish this
extension,many people are using it.

after some days I find some new information I want to add it to
database.can I add data on-line,so that

users can use the new data on database.Is it possible and how?

And would you please tell me how can I use sqlLite?would you please
introduce any reference?

Please guide me

Thanks
