Hi,
What I mean is that a same database (or just some tables) is "cut" into parts, and each of those parts are located in
differentplaces.
For instance, a table TestTable(id int8 not null, first varchar(10), second varchar(15), primary key(id)) exists on
siteA and on site B.
Rows are inserted into site A table; different rows are inserted into site B table.
When a query is done on that table from one of those sites (like "select * from TestTable;"), the result is the list of
allrows from TestTable of site A together with all rows from TestTable of site B, as if it was a single local table.
Another example is that a table TestTable exists on site A, a table OtherTable exists on site B, and relationship
existsbetween those tables via, let's say, foreign key. Local queries using both tables should be possible.
This explanation may not be very clear, please tell me if that is the case.
