Hello,
I am an "old" DB-User in the real sense of the word (I am over 70!).
In the 90ies I got into DB2 as a systems engineer at IBM. Then, around
the turn of the millenium, I set up a database for the administration of a
50-piece wind band, using Lotus-Approach (DBase...). It was fine
but I wanted to go "Open Software" and - when stumbling onto
StarOffice/OpenOffice and Base - it was clear to me to go for that
"scene". Since then I have been using MySQL as external back-end
and must say I am more than happy with it. My DB consists of some
80 interconnected tables/views with record numbers up to around
40.000. This is handled perfectly fine by MySQL (maybe MariaDB in the
near future!).
Of course - as an "old" DB-guy I have no qualms about using the
command-line mysql client directly for doing things like defining
DBs, tables, views, foreign keys etc. Therefore, if there are any limitations
in the LO-front end, it is o.k. for me.
I do feel strongly though, that if we ever want LO to become a REALLY
important player (especially within the business world!), a stable, scalable
interface to REAL databases (with sometimes millions of DB-tuples) will
have to be implemented. Internal, integrated backends are o.k. for
playing around but NOT for mission-critical, large-scale operations.
Regards
Heinz

One advantage of Base is that it can connect to such a wide range of other
database programs.  It is kinda the default way of using Base.  MS Access
can be twisted into using an external database but it's not as easy to
set-up that way as Base.

Kexi and other front-ends can be used either alongside Base or on other
systems by other users to use the same external back-end as the Base users
connect to.  Again this "playing well with others" is a huge advantage that
Access doesn't have by default.


Sadly the marketing team, if and when they ever mention Base, focus on
using the internal back-end and never even mention the advantages that Base
has.  This could be one reason why we see so many people using the internal
back-end and comparing it negatively against Access.

Unfortunately the marketing team took such strong offence to my objections
to their attempts to market Base on it's weakest points instead of it's
strength that they banned me from posting to their mailing list at all.
Sometimes i am really not a "people person"!


I think if we do mention specific back-ends, especially if they are owned
by Oracle, then it is well worth pointing out other names.  It's not about
fanboyism, just about showing there are a wide range of choices - and that
people might well already have a database (or even spreadsheet) that can be
used without any export-import conversions.  It is VERY good to know that
use of internal back-end can be externalised fairly easily without having
to go through all the troubles Ian Whitfield went through.  On the other
hand his move away from Java-based back-ends probably gave additional
benefits!


I definitely appreciate Andreas' posts in this thread!  He has cleared-up
several mysteries by explaining the problems "under the bonnet".  It has
also been good to see experienced and knowledgeable people giving anecdotal
confirmation of Andreas' points.

In answer to Jay's question there was some attempt to move to using
"Firebird" rather than "HSqlDb" but i think that is still an "experimental
feature" and that we now effectively have a choice of 2 internal back-ends
neither of which work entirely as hoped for yet.  With Firebird it feels
like it is "on the way" though.
Regards from
Tom :)

Apparently another great database program to use as a back-end is
Postgresql.  Some of the Postgresql people worked with the LibreOffice
people to make a really good connector and then got that connector into
LibreOffice main trunk.

This is not a matter of partisanship, fanboyism nor objective evidence
of the better product. The important thing is that you are able to
connect to whatever you already have. The database of your online shop,
your business software, your accounting software, some dBase directory,
spreadsheets or csv files. The connectivity feature lets you use tabular
data without troublesome export/import.

If all you have is an embedded HSQLDB, you can convert this to HSQL 2
within minutes. Conversion into Postrgre/MySQL/whatever would require
careful editing of SQL scripts, testing and possibly adjustment of
queries, forms, reports.
