How to treat several identical database as one.
Posted in 1996
Our Informix-4GL based system will soon be used at several sites in
the same organisation i.e. several machines each with a copy of the
application and a database. We want to run a PC-based reporting tool
that can report across all the databases.
Our first idea was to create a new database with views of the form
create view job as
select * from server1@machine1:job
union
select * from server2@machine2:job
union
select * from server3@machine3:job
i.e. create a 'pseudo-table' which appears as all the data from all
the job tables on the three servers.
Unfortunately views do not support unions. Any ideas????
We don't want to replicate the data just make all the similar tables
appear as one table so the PC-base reporting tool (GQL) can be used
by 'normal' users? i.e. non-techines.
