BAM API's for Custom Dash board?

Hi group,

BACKGROUND:-   I am working on a project where we are prviding frame work 
for the Biztalk Developers for streamlining the Development process. We
have 
our Custom Dash board to monitor the activities of various Interfaces
running 
in the organization. This dash board is using the BAM Infrastructure. we
are 
using BAM API's in our tracking components.Now we are upgrading our whole 
biztalk infrastructure to BTS2006. 

PROBLEM:- we were using our own SQL queries (Leveraging some views in BAM 
infrastructure)to retrieve the data from the BAM Tables into our Custom 
Dashboard.
But now we are facing lot of performance issues in our dash board which we

found difficult to solve as we dont have flexibility in using BAM Tables.

HELP NEEDED:- Now i want to know are there any API's exist in BTS2006 for 
retrieving the Data from BAM Tables into our custom dash board(Please note
i 
am not talking about BAM tracking API's) or are there any best practices
to 
retrieve the data from the BAM Tables into Custom Dashboard. 

with advance thanks
