We all are looped on Internet,
thus the most widespread transport protocol is HTTP,
and the most general format for data is XML (XHTML).
When we made

create table a (
id num primary key,
data float
);
create table b (
id num primary key,
ref num references a(id),
data float
);
create table c (
id num primary key,
link num references b(id),
data float
);
insert into a values (1, 12.3);
insert into b values (10, 1, 23.4);
insert into b values (20, 1, 34.5);
insert into b values (30, 1, 45.6);
insert into c values (100,10,56.7);
insert into c values (101,10,67.8);
insert into c values (200,20,78.9);
insert into c values (201,20,89.1);
insert into c values (300,30,91.2);

we need simple request 'a.b.c' to get

<a id=1 data=12.3>
<b id=10 data=23.4>
<c id=100 data=56.7/>
<c id=101 data=67.8/>
</b>
<b id=20 data=34.5>
<c id=200 data=78.9/>
<c id=201 data=89.1/>
</b>
<b id=30 data=45.6>
<c id=200 data=91.2/>
</b>
</a>

Request 'a.b.c' allow to avoid php,etc,
that is very necessary for unskilled users!

User sends to remote database (HTTP will ask login):
c:/dir> xml2http.exe database.my.com username password a.xml
for example
c:/dir> dbf2xml.exe a.dbf | xml2http.exe database.my.com username password

User sends to local database (at transformation data between DBMS-s):
c:/dir> xml2http.exe 127.0.0.1 username password a.xml
for example
c:/dir> dbf2xml.exe a.dbf | xml2http.exe 127.0.0.1 username password

Database sends to local file (at transformation data between DBMS-s):
sql> copy a.b.c to filename.xml;
Database sends to remote database
(if fields username and password of table sys are equal null,
then database sends as 'anonymous'):
sql> update sys set
ral="database.remote.com",
username="tomson",
password="my_pwd";
sql> a.b.c ;
or
sql> update sys set
ran="101.102.103.104",
username="tomson",
password="my_pwd";
sql> a.b.c ;
or if you prefer to export per table
sql> update sys set ral="database.remote.com";
sql> create view av as select * from a where ...
sql> create view bv as select * from b where ...
sql> create view cv as select * from c where ...
sql> av ;
sql> bv ;
sql> cv ;
