Detailed explanation-1: -Structured data is a standardized format for providing information about a page and classifying the page content; for example, on a recipe page, what are the ingredients, the cooking time and temperature, the calories, and so on.
Detailed explanation-2: -Common examples of structured data are Excel files or SQL databases. Each of these have structured rows and columns that can be sorted. Structured data depends on the existence of a data model – a model of how data can be stored, processed and accessed.
Detailed explanation-3: -You can store structured data in relational databases and manage it using structured query language (SQL). SQL lets you define a data model called a schema under which you determine preset rules-such as fields, formats, and values-for your data.
