Hi!
I am a PhD student, researching on using databases to implement network
control infrastructure. For this purpose, I wanted to use conditional tables
<http://users.encs.concordia.ca/~grahne/papers/conditional.pdf> in
databases, which allow representing unknown values in a DB with conditions
over tuples. However, I could not find any DBMS that supports them. Are
there any postgres extensions/features that implement conditional tables? I
wanted to confirm by asking here in case I missed something in my search.
Thanks in advance!
Best,
Mubashir
