Big Data has become a reality that cannot be ignored. In one of my previous posts, I explained the reason for the adjective big that sits before data to create big data. I mentioned that big is not just refereeing to volume, but also to variety and velocity of growth. Big data not only is big in size, but is fast in getting bigger and it covers a variety of data sources that exceed the boundary of the existing relational systems such as CRM and ERP.
I thought may be a post to give some examples of unstructured big data may interest many readers, so below I have bullet pointed some and I may update this post in future when I come across more examples.
- Detailed machine generated data, such as equipment logs, RFID tags
- Sensor generated data such as in manufacturing, metering, condition monitors
- Web related data, such as visitors, hits, keywords, times, etc
- Social Media data such as twitter, facebook comments, feedbacks, etc
- books, journals and text base documents
- Scanned records
- Audio files
- Video files
- GIS and map related data files
- Body of email messages
- Web page contents such as static pages or blogs and wikis
- Image data such as spatial and auto cad images
