The main sources of Big Data are data generated by machines, people, and organisations.
- Machine generated data we refer to data generated from real time sensors in industrial machinery or vehicles that logs that track user behaviour online, environmental sensors or personal health trackers, and many other sense data resources.
- Human generated data, we refer to the vast amount of social media data, status updates, tweets, photos, and medias.
- Organisational generated data we refer to more traditional types of data, including transaction information in databases and structured data open stored in data warehouses.
- Real value often comes from combining these streams of big data sources with each other and analysing them to generate new insights.
Big data can be either structured, semi-structured, or unstructured
