So I finally got my test plan accepted for a 1 month trial to the Oracle Public Cloud at https://cloud.oracle.com/ .
Some initial thoughts- this Java cloud seemed more suitable for web apps, than for data science ( but I have to spend much more time on this).
I really liked the help and documentation and tutorials, Oracle has invested a lot in it to make it friendly to enterprise users.
Hopefully the Oracle R Enterprise ORE guys can talk to the Oracle Cloud department and get some common use case projects going.
In the meantime, I did a roundup on all R -Java projects.
They include- (more…)
I really like the design, course structure and Hadley Wickham (in no particular order) as part of R Studio’ training suite which may be new, but is much better and open. Again I think Oracle’s training is awesome for online features , but some body needs to step up and create a credible R certification here. More power to R ;)
Check it out-
I really liked the course developed by 10 gen for MongoDB (there are two tracks for Developers and DBAs at https://education.10gen.com/)
The interface is very nice and is a step upwards from Coursera’s ( https://www.coursera.org/) pioneering work (and even http://www.codecademy.com/#!/exercises/0 )- each video has a small question, the videos are not cluttered, and the voice and transcription quality is impeccable. Lastly a certification for people who clear 65% acts as an academic incentive, they get a certificate.
yes it is free.
Oracle recently launched a series of nicely made R tutorials at https://apex.oracle.com/pls/apex/f?p=44785:24:0::NO::P24_CONTENT_ID,P24_PREV_PAGE:6528,1but I wish Oracle R had some certifications too!
If only more techie companies like SAS Institute (expensive SAS training), IBM (cluttered website), Revolution Analytics (expensive partners in Certification), Google (unpolished Python lectures)
put an effort with polished e-learning interfaces than be dependent on external partners…..or internal gurus…interfaces matter especially in education.
Happy Mongo DBing/ Oracle R!
- Free Online MongoDB Classes are now live (10gen.com)
- [Python Slide] Developing RESTful Web APIs with Python, Flask and MongoDB (clasense4.wordpress.com)
Some slides I liked on cloud computing infrastructure as offered by Amazon, IBM, Google , Windows and Oracle
Udacity is a smaller player but welcome competition to Coursera. I think companies that have on demand learning programs should consider donating a course to these online education players (like SAS Institute for SAS , Revolution Analytics for R, SAP, Oracle for in-memory analytics etc)
Coursera is doing a superb job with huge number of free courses from notable professors. 111 courses!
going being sponsored to a Government of India sponsored talk on Big Data Analytics at Bangalore on Friday the 13 th of July. If you are in Bangalore, India you may drop in for a dekko. Schedule and Abstracts (i am on page 7 out 9) .

13 July 2012 (9.30 – 11.00 & 11.30 – 1.00)
Big Data Big Analytics
The talk will showcase using open source technologies in statistical computing for big data, namely the R programming language and its use cases in big data analysis. It will review case studies using the Amazon Cloud, custom packages in R for Big Data, tools like Revolution Analytics RevoScaleR package, as well as the newly launched SAP Hana used with R. We will also review Oracle R Enterprise. In addition we will show some case studies using BigML.com (using Clojure) , and approaches using PiCloud. In addition it will showcase some of Google APIs for Big Data Analysis.
Lastly we will talk on social media analysis ,national security use cases (i.e. cyber war) and privacy hazards of big data analytics.
Here is a brief interview with Alvaro Tejada Galindo aka Blag who is a developer working with SAP Hana and R at SAP Labs, Montreal. SAP Hana is SAP’s latest offering in BI , it’s also a database and a computing environment , and using R and HANA together on the cloud can give major productivity gains in terms of both speed and analytical ability, as per preliminary use cases.
Ajay- What made the R language a fit for SAP HANA. Did you consider other languages? What is your view on Julia/Python/SPSS/SAS/Matlab languages
Blag- I think “R” is a must for SAP HANA. As the fastest database in the market, we needed a language that could help us shape the data in the best possible way. “R” filled that purpose very well. Right now, “R” is not the only language as “L” can be used as well (http://wiki.tcl.tk/17068) …not forgetting “SQLScript” which is our own version of SQL (http://goo.gl/x3bwh) . I have to admit that I tried Julia, but couldn’t manage to make it work. Regarding Python, it’s an interesting question as I’m going to blog about Python and SAP HANA soon. About Matlab, SPSS and SAS I haven’t used them, so I got nothing to say there.
Ajay- What is your view on some of the limitations of R that can be overcome with using it with SAP HANA.
Blag- I think mostly the ability of SAP HANA to work with big data. Again, SAP HANA and “R” can work very nicely together and achieve things that weren’t possible before.
Ajay- Have you considered other vendors of R including working with RStudio, Revolution Analytics, and even Oracle R Enterprise.
Blag- I’m not really part of the SAP HANA or the R groups inside SAP, so I can’t really comment on that. I can only say that I use RStudio every time I need to do something with R. Regarding Oracle…I don’t think so…but they can use any of our products whenever they want.
Ajay- Do you have a case study on an actual usage of R with SAP HANA that led to great results.
Blag- Right now the use of “R” and SAP HANA is very preliminary, I don’t think many people has start working on it…but as an example that it works, you can check this awesome blog entry from my friend Jitender Aswani “Big Data, R and HANA: Analyze 200 Million Data Points and Later Visualize Using Google Maps “ (http://allthingsr.blogspot.com/#!/2012/04/big-data-r-and-hana-analyze-200-million.html)
Ajay- Does your group in SAP plan to give to the R ecosystem by attending conferences like UseR 2012, sponsoring meets, or package development etc
Blag- My group is in charge of everything developers, so sure, we’re planning to get more in touch with R developers and their ecosystem. Not sure how we’re going to deal with it, but at least I’m going to get myself involved in the Montreal R Group.

SAP HANA is SAP AG’s implementation of in-memory database technology. There are four components within the software group:
- SAP HANA DB (or HANA DB) refers to the database technology itself,
- SAP HANA Studio refers to the suite of tools provided by SAP for modeling,
- SAP HANA Appliance refers to HANA DB as delivered on partner certified hardware (see below) as anappliance. It also includes the modeling tools from HANA Studio as well replication and data transformation tools to move data into HANA DB,
- SAP HANA Application Cloud refers to the cloud based infrastructure for delivery of applications (typically existing SAP applications rewritten to run on HANA).
R is integrated in HANA DB via TCP/IP. HANA uses SQL-SHM, a shared memory-based data exchange to incorporate R’s vertical data structure. HANA also introduces R scripts equivalent to native database operations like join or aggregation. HANA developers can write R scripts in SQL and the types are automatically converted in HANA. R scripts can be invoked with HANA tables as both input and output in the SQLScript. R environments need to be deployed to use R within SQLScript
