Why XML is unstructured data?

Is CSV a structured data?

Why is XML considered semi-structured?

XML is widely used to store and exchange semi-structured data. It allows its user to define tags and attributes to store the data in hierarchical form. Schema and Data are not tightly coupled in XML. Object Exchange Model (OEM) can be used to store and exchange semi-structured data.

Is HTML structured data?

HTML is semi-structured, because we can organize different kind of data in tags.

What are structured data types?

A structured type is a user-defined data type containing one or more named attributes, each of which has a data type. Attributes are properties that describe an instance of a type. A geometric shape, for example, might have attributes such as its list of Cartesian coordinates.

What are structured and unstructured data?

Models: Structured data has a predefined data model and is formatted to a set data structure before being placed in data storage (e.g., schema-on-write), whereas unstructured data is stored in its native format and not processed until it is used (e.g., schema-on-read).

Why PDF is unstructured data?

It is as accessible as data written on a piece of paper since some PDFs are designed to transfer information to us, humans, but not computers. Such PDFs can contain unstructured information that does not have a pre-defined data model or is not organized in a pre-defined manner.

How does Google use structured data?
