How do we put JSON data format in standard RDBMS? Hey, we also have XML format from other sources. Other system give us compressed data in gzip format. CHALLENGES ANALYTICS IS IN YOUR BLOOD ANALYTICS Do you realize that you do analytics everyday? I need to go to campus faster! Hmm.. Looking at the sky today, I think it’ll be rain. ANALYTICS Atomic Ideas LifeCycle Explore all the ideas! Analytics Analytics ANALYTICS TOOLS Life Cycle 1 RapidMiner provide built-in RDBMS connector, parser for common data format (csv, xml), data manipulation, and many machine learning algorithm. We can also create our own library. Latest version of RapidMiner can connect to Hadoop and do more complex analysis like text mining. Free version is available (community edition). 2 KNIME. Known as a powerful tools to do predictive analytics. Overall function is similar to RapidMiner. Latest version of KNIME can connect to Hadoop and do more complex analysis such as text mining.
