DStream makes simple things simple
- The perfect fit for the 90% of projects that just need simple aggregation
- No cubes, no MDX - everything is done (easily) in code
- Dimensions don't need to be defined up front, just add them to the data as you need them
Aggregate over any time frame
Exceptional Read Performance, Great Write
- Easily define your own custom calendar to aggregate over
- Built in "standard" calendar aggregations
- All hierachy levels can be aggregated by whatever time frame you want
Exceptional Read Performance, Great Write
- DStream precalculates all aggregates, so read performance is exceptional
- DStream Remote uses a brutally efficient binary format to get your data to you as quickly as possible. It excels in low bandwidth scenarios
- A simple stream can handle thousands of data points a second
- A sophisticated hierachy handles hundreds of points a second - whereas conventional OLAP can take minutes / hours just to process
Documentation
Does DStream Support MDX?
No. We have a like/hate relationship with MDX - we like it because it is really clever - and we hate it for the same reason. We think it falls at the first hurdle of keeping simple things simple. Others of course would disagree - but DStream is the
product of our need to get things done, today - and just as importantly make them maintainable and understandable in the future.
Why use DStream instead of conventional OLAP?
First of all, it is not an exclusive choice. DStream complements conventional OLAP extremely well - you can use DStream for real time updates to your core metrics, as well as handling the data storage.
But if you need a system that keeps all data up to date in a matter of milliseconds, conventional OLAP is just not an option.

- Samples
- Programmers reference
Why use DStream instead of conventional OLAP?
Fantastic Read Performance
- DStream precalculates all aggregates, so read performance is exceptional
- Scale up your own database as required - no special knowledge needed
- DStream Remote uses a brutally efficient binary format to get your data to you as quickly as possible. It excels in low bandwidth scenarios
Great Write Performance
- A simple stream can handle thousands of data points a second
- A sophisticated hierachy handles hundreds of points a second - whereas conventional OLAP can take minutes / hours just to process
- Data is available the moment it is written, and all levels of the hierachy can be listened to
DStream stores data in standard databases
Don't learn about a different datastore (like a cube)
- It's easy to manage
- The familiarity of using your own database outweighs any other concerns for many projects
- We use a really simple datamodel.
- Databases supported include SQL Server 2005 / 2008, MySql 5, Oracle 9/10, Postgres 8, SQLite 3 (need another? let us know and we will see what we can do)
- We don't use a proprietary datastore that requires additional knowledge to use
- Takes about 2 minutes to learn
DStream solves all of your data warehousing problems
- DStream lets you use real time data for precalculated aggregates
- DStream is a great basis for your business intelligence solution
- DStream complements web 2.0 with a high performance solution
- build business intelligence dashboards really really easily
- DStream lets you work in any .net language, including c# and vb.net
