How are the tables in the XI structured?

Question

Hi,
I am trying to create a report contaning a list of idoc interfaces that we have in the XI. For this I need to know which tables the information about receiver determination, receiver agreements etc. is saved at.
I have found some tables which seem helpful for this, but there is a more fundamential question bothering me first: Is all the metadata actually saved in tables like TRD_RELATION and SSRVSERVICE or is it just cache?
If it's only cache information (and not all the data is there at all times), then is there a place where I can get that data from?
If it isn't cache and all the data I need can be found in the XI tables, then I have a few questions regarding them.
I have read the blog <a href="/people/sravya.talanki2/blog/2005/12/02/sxicache--ripped-off:///people/sravya.talanki2/blog/2005/12/02/sxicache--ripped-off
and it helped me understand a bit which useful tables there are, but I still don't know about the relationships between them. For example, the values in the object_id field in table SSRSERVICE are not the same as in any of the other tables I have checked. Also, I don't understand exactly what the role of table TRD_EXTRACTOR is. It looks like a table of all the objects in the system, but how do I know what type [for ex. service, party, BPM] each object is?
Thanks in advance for any replies.

Hi Udi,
the access parameters to the java tables are stored in the exchange profile.
In your integration builder navigate to --> link administration -> chose tab REPOSITORY --> Adminsiatration and properties --> Exchange profile.
ABAP and JAVA stack communicate via http. But I am sure there are some function modules in the ABAP stack to retrieve the table informations you need.
(See e.g transaction SXI_CACHE; there are some informations from JAVA stack)
<b>If you found some, let me know!</b>
Send me a mail (in my business card there is my adress): I will give you further information.
