"The Rights and Wrongs of the NoSQL Phenomenon" with Dr. C. Mohan

Please join Oracle and Big Data Solutions Integrator Lilien Systems for an insightful session with Dr. C. Mohan (IBM Fellow and Former IBM India Chief Scientist). Dr. C. Mohan has been an IBM researcher for 32 years in the information management area, impacting numerous IBM and non-IBM products, the research community and standards, especially with his invention of the ARIES family of locking and recovery algorithms, and the Presumed Abort commit protocol. This IBM, ACM and IEEE Fellow has also served as the IBM India Chief Scientist. In addition to receiving the ACM SIGMOD Innovation Award, the VLDB 10 Year Best Paper Award and numerous IBM awards, he has been elected to the US and Indian National Academies of Engineering, and has been named an IBM Master Inventor. This distinguished alumnus of IIT Madras received his PhD at the University of Texas at Austin. He is an inventor of 40 patents. He serves on the advisory board of IEEE Spectrum and on the IBM Software Group Architecture Board’s Council. More information can be found in his home page at

On our upcoming talk, Dr. C. Mohan will describe some of the recent developments in the database management area, in particular the NoSQL phenomenon and the hoopla associated with it. Based on his more than three decades of database systems work in the research and product arenas, Dr. Mohan will outline what are many of the pitfalls to avoid since there is currently a mad rush to develop and adopt a plethora of NoSQL systems in a segment of the IT population, including the research community. In rushing to develop these systems to overcome some of the shortcomings of the relational systems, many good principles of the latter, which go beyond the relational model and the SQL language, have been left by the wayside. Now many of the features that were initially discarded as unnecessary in the NoSQL systems are being brought in, but unfortunately in ad hoc ways. Hopefully, the lessons learnt over three decades with relational and other systems would not go to waste and we wouldn’t let history repeat itself with respect to simple minded approaches leading to enormous pain later on for developers as well as users of the NoSQL systems! More elaboration of this talk's points could be found in the paper at 

Caveat: What Dr. C. Mohan expresses in this talk are his personal opinions and they do not necessarily reflect the opinions of his employer.
