C. Mohan, IBM Research - Almaden - CS Distinguished Lecture Series

C. Mohan IBM Fellow, IBM Almaden Research Center May 1, 2015 "Big Data: Hype and Reality" Abstract - Big Data has become a hot topic in the last few years in both industry and the research community. For the most part, these developments were initially triggered by the requirements of Web 2.0 companies. Both technical and non-technical issues have continued to fuel the rapid pace of developments in the Big Data space. Open source and non-traditional software entities have played key roles in the latter. As it always happens with any emerging technology, there is a fair amount of hype that accompanies the work being done in the name of Big Data. The set of clear-cut distinctions that were made initially between Big Data systems and traditional database management systems are being blurred as the needs of the broader set of (“real world”) users and developers have come into sharper focus in the last couple of years. In this talk, I will survey the developments in Big Data and try to distill reality from the hype! “Modern Database Systems: Modernized Classic Systems, NewSQL and NoSQL” Abstract - The last many years have seen the emergence of a new class of database systems which I am calling Modern Database Systems (MDS). They are classified broadly as NoSQL and NewSQL systems. Apart from the development of such systems, traditional DBMS vendors have also extended their decades old systems like DB2, Informix, Oracle and SQL Server with major architectural enhancements that address modern requirements and take advantage of hardware (processor, memory and storage) advances. This talk will do a broad brush analysis of MDS. It is targeted at a broad set of database systems and applications people. It is intended to let the audience better appreciate what is really behind the covers of many of these systems, going beyond the hype associated with these open source, commercial and research systems. The capabilities and limitations of such systems will be addressed.
