We use FrontBase for an application that does mostly large, complex

- The database process crashes sometimes due to various queries
that it doesn't like
Usually this is a parser bug and they have always fixed them
quickly. But it is definitely not something you want to find on an
app in production.
- Left join performance is bad
- Legacy left join syntax can return incorrect results
- OR performance is bad
Yes, something odd is going on there.
- Multi-column indexes only allow a range of values for the last
column of the index - resulting in bad performance
I have not run into this one. Can you elaborate on this?
- Adding columns to large tables can take hours and makes the DB
unresponsive
So I would say that FrontBase is great for applications that do
simple, fast queries, but maybe not if your needs are more demanding.
