Unstructured Data

Random data is actually everything else. Random data has an internal structure but is not organized by predefined data models or by schema. It can be text or non-text, and man-made or machine. It can also be stored within non-relationship data such as NoSQL.

General unplanned personal data includes:

Text files: Word processing, spreadsheets, presentations, email, logs.
Email: Email has some internal structure because of its metadata, and we sometimes call it a less structured one. However, its message field is not built and traditional analytics tools cannot process it.
Social Media: Data from Facebook, Twitter, LinkedIn.
Website: YouTube, Instagram, photo sharing sites.
Mobile data: Text messages, locations.
Communication: Chat, IM, phone recording, interactive software.
Media: MP3, digital photos, audio and video files.
Business applications: MS Office documents, production applications.
Typical randomly generated data includes:

Satellite imagery: Weather data, earth forms, military movements.
Scientific details: Oil and gas exploration, space exploration, seismic images, space data.
Digital rental: Viewing and video images.
Sensor data: Traffic, weather, oceanographic sensors.
