You probably heard the term Big Data<\/a> — it is one of the most hyped terms now. But what exactly is big data?<\/p>\n Big Data is very large, loosely structured data set that defies traditional storage<\/p>\n Human Generated Data<\/a> is emails, documents, photos and tweets. We are generating this data faster than ever. Just imagine the number of videos uploaded to You Tube and tweets swirling around. This data can be Big Data too.<\/p>\n Machine Generated Data is a new breed of data. This category consists of sensor data, and logs generated by ‘machines’ such as email logs, click stream logs, etc. Machine generated data is orders of magnitude larger than Human Generated Data.<\/p>\n Before ‘Hadoop<\/a>‘ was in the scene, the machine generated data was mostly ignored and not captured. It is because dealing with the volume was NOT possible, or NOT cost effective.<\/p>\n Original big data was the web data — as in the entire Internet! Remember Hadoop was built to index the web. These days Big data comes from multiple sources.<\/p>\nHuman Generated Data and Machine Generated Data<\/h4>\n
