postheadericon Oracle Database Under Threat in SAP Shops?

A number of reporters visiting the Mastering SAP event in Sydney, Australia, wrote that there is a buzz among SAP customers who run their systems on Oracle databases to think about changing their database strategies in the future.

When asked about which database they would likely be migrating to in the future in an informal survey, the majority answered surprisingly: Microsoft SQL Server.

Here’s a quote from BusinessInsider.com that explains why this is actually not so surprising:

It’s attractive because it offers technology similar to SAP HANA (features known as columnar and in-memory storage) and its prices start at $11,000 per terabyte. It can run on comparatively lower-cost hardware such as new servers by Dell, too. Microsoft and SAP have been partners for years.

So why not chose SAP’s new HANA database then? ZDNet says the following about this:

When it came around to a discussion on HANA, there was much debate about whether customers will put their OLTP systems on this as yet to be available database. The question in my mind is whether there is any real advantage in moving to HANA which today, can provide huge speed improvements in analytic style scenarios. The answer is a heavily qualified ‘maybe.’ HANA’s columnar store thrives on complex aggregation queries but is slow when trying to replicate what amount to row store calculations where an Oracle performs very well.

postheadericon Erosion in Interest to Develop for Android due to Growing Fragmentation

The Register published the following news on their website a few days ago:

A new study conducted by IDC and mobile-developer platform and services company Appcelerator has determined that as Google’s open source Android operating system becomes more and more fragmented, fewer and fewer developers are putting it on their “must-code-for” list.

When this subject comes up, I always point to these statistics, published by Tweetdeck in October 2010:

If the Android ecosystem was that fragmented already 18 months ago, consider how fragmented it is nowadays now that we have Android 3.0 (Honeycomb) and 4.0 (Ice Cream Sandwich) added to the equation.

Oh, and don’t forget about tablet support that was added to Android 3.0, which makes the number of screen sizes and types of hardware even more diverse than it was 18 months ago.
