Data vs. Information

Data is raw facts or figures without context.
Information is processed, organized, and interpreted data, having meaning and being actionable.
Data lacks inherent meaning, information provides understanding and supports decision making.
Data is objective and quantifiable, information can be subjective and qualitative.

Structured vs. Unstructured Data

Structured Data: Presented in a tabular format, organized in rows and columns, with clearly defined attributes for each data element.
Examples: Data from a spreadsheet, database, or a simple table of employee information is structured. Columns of age, name, and department are pre-defined.
Unstructured Data: Data is presented in a less organized manner, lacking a fixed format or structure. Data is free-form text, making organization more challenging.
Examples: A paragraph or a conversation transcript, emails, or social media posts is unstructured.
Semi-structured Data: Data includes some organization structure, such as tags or codes, rather than completely rigid structures.
Examples: XML (Extensible Markup Language) or JSON (JavaScript Object Notation) formatted data.
