data warehousing discussion

William Inmon introduced the phrase "data warehouse" in 1990. He defined it as a managed database in which the data is:
- subject-oriented
- integrated
- time-variant
- nonvolatile
This last characteristic of the DW defined by Inmon cannot always be applied;
the DW isn't completely read-only. In addition, Inmon says:
"The technology supporting backup and recovery, transaction and data integrity,
and the detection and remedy of deadlock is quite complex and unnecessary for
for data warehouse processing.".
Backup and recovery seem as an important issue in data warehousing for me.
I would like to open this discussion with persons that are working in the warehousing field or who are interrested in it, and to do so, please post your answers on this group.
Regards,
Nadia.
