- Abstract
- Data warehouses materialize views in order to provide fast access to
information, but the correctness also should be maintained. The notion of selfmaintenance
can be a goal that defined as maintaining views by materializing
supplementary data. Incremental update mechanisms can now be prospective
way to the goal. A discussion with extensive literature is generated on several
issues with maintaining data warehouse views. There are issues related to the
data warehouse view maintenance: algebraic approaches, the concurrency
control problem, database rule related problems. Motivating example derived
from TPC-D database is suggested in terms of incremental base relation
method, auxiliary view method, and differential method respectively. After
quantitative dealings and qualitative measures are reviewed, it is concluded that
the differential method is superior to the others in that it is a true selfmaintenance
method and it does not burden the current base relations.
