7. Data Access and Storage
VertiPaq
In-memory column store… typical 10x
compression
Brute force memory scans… high
performance by default… no tuning required
Basic paging support… data volume mostly
limited to physical memory
MOLAP
Disk based store… typical 3x compression
Disk scans with in-memory sub-cube
caching… aggregation tuning required
Extensive paging support… data volumes
can scale to multiple terabytes
DirectQuery
Passes through DAX queries & calculations…
fully exploits backend database capabilities
No support for MDX queries… no support for
data sources other than SQL Server (in
Denali)
ROLAP
Passes through fact table requests… not
recommended for large dimension tables
Supports most relational data sources… no
support for aggregations except SQL Server
indexed views
