Scott, Joe, et al:
I believe Rob Cozens does something of the sought [partially load
a db stack] with Serendipity, but the question is whether it's
really worth while given it's all there already with a "real"
database.
I've followed this thread this far wondering "should I bother to
mention SDB, considering the underwhelming response it has received
from the RunRun community?"
Scott & Andre might offer some insight in this regard, as both have
at least looked at SDB. I've had eConversations with others who
said they would look at SDB; but no followup questions,
suggestions, or complaints. So I don't know if folks found it
unsuitable or incomprehensible (Paul L., Our issues were different:
you wanted SDB to work like EpsiTalk, which it could not do due to
the issue Scott noted above--the entire database stack _is_ loaded
in RAM & must be updated when one record changes.)
If a "real" database must by definition only partially load to RAM,
then SDB is not a "real" db. OTOH, SDB supports multiuser client/
server access with both automatic & programatic record locking and
multiple record search & retrieval via binary searches of indexed
records in a Revolution db stack. But compared to a "real"
database, once the db stack is opened, 0 disk accesses are required
to retrieve any record. And note that in a client/server setup,
only the server app sees the entire db stack, while the client
front end stacks deal with data on a record-by-record basis. Also
since SDB is 100% native Transcript, it is 100% cross platform
compatible and requires no externals. I'll cut my promo short and
note SDB is open source and free of royalty charges.
For some time Andre Garzia graciously provided download access to
Serendipity Library (which includes SDB) at wecode.org. Andre and
I have had some discussions about reinstating the download site
once I was ready to release SDB II (which supports binary data in
addition to text); but lacking any expression of interest from the
RunRev community and faced with emerging issues (CA Marine Life
Protection Act implementation, wave energy generation, and marine
aquaculture) in my other area of focus, SDB II testing isn't high
on my list.
As always, the source code, utilities, and example db stacks are
available, and I'd certainly have more interest in working on it if
someone else found it useful.
