It is also possible to configure SQL Server databases to use point in time
consistent reads. See READ_COMMITTED_SNAPSHOT in the documentation. This
feature reduces blocking, but the first release had a few performance issues.
One nice feature is you can include columns in an index that are not part of
the key so changes in the column value result in an update to the index row
rather than a delete insert as when the column is part of the key.

Hi all
Trying to decide between oracle and sql server for a query/warehousing
type database. Can anyone share their input or point to a paper for
the current versions. Thanks

Hi Orlando!
SQL Server enterprise edition comes with what Oracle calls "In-Memory
option" and partitioning, no further licensing required. SQL Server
doesn't have multi-versioning which makes things simpler for mostly
query database. On the flip side, readers block writers and vice versa,
which means that loading usually means downtime. SS has something called
"always on availability groups", which allows you to maintain shared
nothing "cluster" with several identical database copies, which can be
queried in parallel. SQL Server supports bitmap indexes and star
(snowflake) schema queries. SQL Server EE is significantly cheaper than
Oracle. I would advise going with SQL Server.
