What is a difference between structured data and semi-structured data?

  1. Structured data has a fixed schema and semi-structured data has a flexible schema.
  2. Only Structured data supports entities.
  3. Structured data has a flexible schema and semi-structured data has a fixed schema.
  4. Only Structured data supports attributes.

Answer(s): A

Explanation:

Structured data
In structured data, sometimes called relational data, all data has the same fields or properties. All the data has the same organization and shape, or schema. The shared schema allows this type of data to be easily searched by using query languages like Structured Query Language (SQL). This capability makes this data style perfect for applications like CRM systems, reservations, and inventory management.

Structured data often is stored in database tables with rows and columns. In the table, a key column indicates how one row in a table relates to data in another row of another table.
Semi-structured data is less organized than structured data. Semi-structured data isn't stored in a relational format because the fields don't fit neatly into tables, rows, and columns. Semi-structured data contains tags that make the organization and hierarchy of the data apparent. One example is key/value pairs. Semi-structured data is also referred to as non-relational or not only SQL (NoSQL) data.
