Dear developers,
As the subject said I have a stupid question, what is the advantages
of compile in a database support like:
--8<---------------cut here---------------start------------->8---
Databases:
Compiling in support for Berkeley database.
--8<---------------cut here---------------end--------------->8---
Can I use this in elisp scripts inside XEmacs, If so, how to use it?
Yes. As far as elisp is concerned it's basically just an external
(ie, on-disk) hashtable. Since you have access to the BDB/dbm
functionality, you can tune it for the mind of access that's most
common.
The PostgreSQL support is much more powerful.
Is there any documents/info pages describe this kind of usage?
Not really. I believe that VM supports keeping information about the
summaries in a dbm or Berkeley db database.
