SEMI-Structured Data

Data that does not are living in a traditional database, but carries tag or marker that make it in part organized. It sits between structured and unstructured data.

Examples:

• JSON and XML documents
• Log files from servers
• Emails with metadata
• Sensor output with predefined fields

Characteristics:

• Flexible shape
• Requires parsing equipment for evaluation
• Supports each established and unstructured queries

Use Cases:

• Web server log analysis for traffic styles
• IoT devices sending semi structured sensor readings
• APIs that provide statistics in JSON/XML formats
