Hi, Mehmet,

Thanks for your interest in FastBit software; sorry that your message 
seemed to have got lost in my inbox.

You are right that FastBit is meant for read-only data.  However, it 
is possible to append and even delete records.  In the documentation 
of ibis::part class, you can find a number of functions related to 
this functionality.

ibis::part::append for adding data to an existing partition 
(alternatively you can use ibis::tablex interface)

ibis::part::deactivate for marking certain rows as not active (i.e., 
not eligible to participate in query answering)

ibis::part::purgeInactive for reorganizing data and removing inactive 
rows.

If you intent to add and delete a small number of rows at a time, 
FastBit is probably not the most appropriate tool for you.

Good luck.

John
