I like this word re-imagination from Mary Meeker’s Internet Trends presentation. We are seeing so many aspects of our life being transformed by the internet. Take for example, ordering a cab to go somewhere. Either we phone for a yellow cab here in California or if you are in New York city, then you stand and wave for an incoming yellow cab to stop. The new game-changer is Uber. All you do is touch your smartphone screen for UberX or Black car and you get an instant message about the car coming in less than 5 minutes time with the driver and car info. It is cheaper and you pay by card (pre-registered in your Uber account). This is re-imagining the transport sector. Uber, a San Francisco company is worth about $17B and is operating in 70 cities around the world. Quite a disruptive force! The following list shows several new alternatives using the internet technolog... (more)

MongoDB World in NY City this week

I attended the MongoDB World in NY city earlier this week on June 24th. and 25th. There were 2000 attendees for this first-time event. I met many people who flew in from all over the world. It was quite a phenomenon for a six-year old company. The momentum of MongoDB  is truly amazing. For those who do not know MongoDB, it’s a new generation open source NoSQL database for building highly interactive modern applications. Enterprises have built “systems of record” over last 3 decades using traditional RDBMS such as DB2, Oracle, MySQL and SQL Server. These systems are like the inte... (more)

NewSQL – What is It?

There has been a lot of discussion on NoSQL databases over the past couple of years. These databases do not use the Structured Query Language (SQL), the standard data manipulation language for relational databases such as Oracle, DB2, MySQL, Sybase, and SQL Server. The data model is closer to object-oriented data and hence fits well for documents or geospatial data. Being schema-less, they accommodate well for flexible data structures, unlike their relational brethren. Examples of NoSQL databases are MongoDB (most popular), CouchDB, and Cassandra. Programming is easier and rigid ... (more)

The Future of Data Management According to Doug Cutting (Father of Hadoop)

I joined 600 people last night at a session sponsored by Hive to listen to Doug Cutting, the creator of Hadoop. Currently he is the chief architect at Cloudera and a director at Apache  Software Foundation. The hall at NetApp facility was overflowing with an eager audience. Doug spoke about the future of data management. He narrated a brief history of Hadoop, how it was founded and how far it has come. As everyone knows, the pedigree of Hadoop came from Google’s GFS (Google File System, now HDFS) and Map-Reduce programming. Here are the key predictions he made: Hadoop has grow... (more)

Real Time Big Data or Data in Motion

Most of the discussions on Big Data begins and ends with Hadoop. It is the commercial version of HPC (High Performance Computing), whose underlying technologies have been around for years: clustering, parallel processing, and distributed file system. In today’s parlance you can read Hadoop clusters on commodity hardware, map-reduce algorithm, and HDFS in that order. There is no doubt that Hadoop has taken off in a big way, but it does not address one big emerging area called real time query and analysis on data that is moving all the time. Data can be categorized into three bucke... (more)
