IBM has taken a new approach to database technology.
One of the most amazing features of dashDB is how it uses compression to get results in lighting speed. dashDB uses advanced processing which doesn't require the entire dataset to fit in memory.
Prefetching of data: Has the ability to anticipate and "prefetch" data just before it's needed and to automatically adapt to keep necessary data in, or close, to the CPU.
No Decompression Required: dashDB preserves the order of data and performs a broad range of operations including joins and predicate evaluations on compressed data, without the need for decompression, drastically speeding the processing of data.
Data Skipping: dashDB's BLU acceleration automatically determines which data would not qualify for analysis within a particular query, enabling large chunks of data to be skipped.
I believe that many organizations need to look at how they are servicing their customers. dashDB doesn't necessarily replace your existing infrastructure. However, as an add-on, you can now expand your overall operations and performance goals.
