Detailed explanation-1: -Structured data is highly specific and is stored in a predefined format, where unstructured data is a conglomeration of many varied types of data that are stored in their native formats. This means that structured data takes advantage of schema-on-write and unstructured data employs schema-on-read.
Detailed explanation-2: -Structured data is when data is in a standardized format, has a well-defined structure, complies to a data model, follows a persistent order, and is easily accessed by humans and programs. This data type is generally stored in a database.
Detailed explanation-3: -Structured data is typically stored in tabular form and managed in a relational database (RDBMS). Fields contain data of a predefined format. Some fields might have a strict format, such as phone numbers or addresses, while other fields can have variable-length text strings, such as names or descriptions.
Detailed explanation-4: -So, structured data is the type of data that is well-organized and accurately formatted. This data exists in a format of relational databases (RDBMSs), meaning the information is stored in tables with rows and columns that are connected.
Detailed explanation-5: -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.
