c-isam datablade server storage: how does it work

c-isam datablade server storage allows to store data in a database tables and access the data with c-isam calls by linking the programs containing the c-isam calls with a new libtisam.a library. How is this technically implemented: does the the data-blade module and the new library reformat the calls in SQL or are special database calls used internally by the product (below the sql layer) to emulate the c-isam calls? Question is to better understand the product mainly towards performance tuning issues. Bernard Dhooghe Sent via Deja.com http://www.deja.com/ Before you buy.
