MVP For 14 Years!

Got awarded for Microsoft Most Valuable Professional (MVP) – Data Platform again. This will make my 14th consecutive year to be recognized by Microsoft for my expertise and contributions to the community! Apparently, it became difficult (or not cost effective) to count years, so the ring is for 2017-2018 but the tower doesn’t lie.

What’s ROI for BI?

I often ask prospects if they’ve done any estimates of the value that the envisioned BI solution would bring to them. The Microsoft Solution Framework actually recommends partners do this during the planning phase. Alas, the answer is almost always negative. Then I ask what criteria would be used to evaluate if my price (I […]

Running ETL on AlwaysOn Primary Replica

Power BI vs. Qlik

After Tableau and SiSense, Keeping ’em Honest continues with Qlik. Now, after they sold the company and took a hit in the latest Gartner’s quadrant, I didn’t expect much of a completion from Qlik but every now and then I run into a customer considering Qlik and willing to share Qlik’s feedback on how Qlik […]

Scaling out SSIS in SQL Server 2017

SQL Server 2017 introduces the ability to scale out SSIS. The primary scenario is to enable customers to scale out their SSIS execution at the package level. Imagine a retail business that has about 300 packages to run at the end of the day to push transactional data/finance data from multiple stores to the centralized […]

Understanding Writeback Target Allocation

I’m working on architecting a financial planning solution powered by Analysis Services Multidimensional. One thing that might not be obvious is how Multidimensional selects the target of writeback allocation. In this case, planning will be done at Customer and Product level. With the default equal allocation when writing at the customer level, it might appear […]
