V4REV on Revolution 2.7?

[Joël Guillod]

The next 3 months I will finally have time to spend in order to  
seriously study and test Valentina for Revolution. I need a multiuser/ 
multiplatform DBMS and I will decide between Valentina, Postgresql  
and MySQL at the end of this study.

Yet I have some problem going throught the Valentina Tutorial. The  
Valentina_Init() seem to work correctly but VDatabase_Open() or  
VDatabase_Create() returns errors. I suspect that this is related to  
the recent Revolution 2.7 release where the installation of the  
development environment has changed (i.e. folders hierarchy with  
plugins and utility). Or maybe the tutorial is not accurate (I just  
found that the script in the pdf tutorial is not quite the same than  
the script in the provided stacks).

So I would be pleased if experienced users can help me in answering  
my questions:
- How to properly install the Valentina plugin/external under Rev 2.7  
IDE? And also under a standalone?
- How do you compare using the standard Revolution database library  
to using the proprietary Valentina API?
- Is one of the method better from the other? In which case (I  
suspect that the proprietary allow for more functionality)?
- Are there any Transcript or stack libraries, or any material which  
could help me in seriously mastering Valentina 2 for Rev?
- Is the "Valentina Developer Network Platform Edition 4 years  
maintenance" a good choice if I intend to distribute an end-user  
application with access to DBMS by 1 to 10 users (rarely much more  
less than 5 users)?
- I will appreciate comments on the good and not so good experiences  
with V4REV 2?
- I found obvious errors in the documentation  
V4REV_Reference_2_en.pdf (for instance on pages 77-79 the handlers  
are prefixed VDatabase_ where VTable_ seem to be expected according  
to context and to page 58). Also handlers like CreateUShortField are  
mentioned but not explained. Then, is there an errata or corrected  
documentation?

Warm thanks for any reply.
