DB examples corrupted? and other questions

[David Vaughan]

Apropos these discussions about databases, I downloaded Tuviah's 
DBExamples to have a look at Valentina but attempting to open either of 
the two examples provided produced the error "unable to open - stack 
corrupted" (more or less).

Are these examples known to be working? I have Rev 2.0.1

Is anyone planning to write a wrapper for SQLite to be used with Rev. 
Clearly, I am not but would be interested in using it.

Of the various DB options for OS X, it appears from a quick scan that:
- mySQL is free, fast and not overly friendly to manage
- PostGRE is free, not as fast but more complete an implementation than 
mySQL
- Valentina is damned expensive for one user on one machine with no 
intention to sell, but very fast (and Tuviah advocates it for 
single-user databases)
- SDB is free, rev-speed and a unique DB language (yes, I know there is 
nothing attractive about SQL anyway)
- ...and of course I could just do it in Rev as my DB size, while not 
very small, does not push limits (<10,000 records, <10MB).

My need is for speed followed by simplicity of use. The design looks 
like three principal tables in the DB and considerable use of live 
searching (e.g. for each keydown) to link data.

Any experiences or commentary welcome.
