Re: alternatives to Firebird: sqlite [was: Firebird doesn't support MSVC 2015]

I understand, but the situation with Firebird seems less than ideal, at least in terms of Windows 
builds at any rate. 

Are the tests really that much slower? Obviously we are relying on having a Java installation to 
test out Base. 

Can we isolate those things that we can test on sqlite to sqlite, and any other things to HSQLDB2 
or H2? If/when sqlite or some other more appropriate embedded database comes along, then we can 
consider switching. 

Oh, and I’m not sure if this brings much to the table, but I wonder if we can simulate joins. After 
all, to get a right join you just swap tables, and you can actually simulate a full outer join with 
just a combination of other joins.
