Hello, FBTeam developers!
I have read the article "The Interbase On-Disk structure" by Ann W.Harrison
http://community.borland.com/article/0,1410,27151,00.html,.
Great and bright.
But I have some "theoretical" questions about building of "internal
database
image".

Here is the sequence as I can imagine this:

1) Read the header page, find the number of 1st pointer page and go there.
2) While reading the 1st poiter page, build the RDB$Pages.
3) After that, read from RDB$Pages -> proceed with RDB$Relations and so
on -
i.e. building the system tables.

I think that some "trick" here. The RDB$Pages creates the first, but if I
SELECT RDB$RELATION_NAME FROM RBD$RELATION, I can see it! And I can see
RDB$Relations itself!

I suppose, than IB engine builds RDB$Pages, it works with it as non-table
(maybe, as array or something else), and than RDB$RELATIONS created, IB
"legalizes" the RDB$Pages as table (and other RDB$?...) - it just write
down
the records into RDB$Relations. And may be something else. :)

So, is it right idea? I cannot find information about internal database
representation.
Can anybody help me and describe the process of creation of internal
database image? Or give me some urls or docs?
Sincerely,
