Summary
Not every database needs to scale to higher magnitudes of capacity, but when a project does grow into the terabytes, SQL Server 2012 provides some advanced technologies to tackle the growth. However, even these advanced technologies are no substitute for smart database design.
Following are key points on partitioning:
- Partitioned views use a union to merge data from several user-created base tables. Each partition table must include the partition key and a constraint.
- The Query Processor can carefully choose the minimum number of underlying tables when selecting through a partitioned view but not when updating.
- Partitioned tables are a completely different technology than partitioned views and use a partition function, schema, and clustered index to partition a single table.
The next chapter wraps up this part covering optimization with features that are available in the Enterprise Edition of SQL Server 2012.
