Which type of data is characterized by regular and predictable formats?

Unstructured data
Structured data
Semi-structured data
Raw data

The correct answer is: Structured data

Structured data is characterized by regular and predictable formats, which makes it easy to enter, store, query, and analyze. This type of data is typically organized in a defined manner, often within databases or spreadsheets, using rows and columns. For example, structured data can include information such as names, dates, addresses, and numeric values, all fitting into specific fields. The regularity and predictability of structured data allow for efficient data operations, including data retrieval and manipulation through SQL queries or data processing tools. This structured nature enhances consistency, accuracy, and the ability to perform analytical tasks quickly. In contrast, unstructured data lacks a predefined format, making it more challenging to process and analyze. Semi-structured data has some organizational properties but does not conform to the strict structure of relational databases, while raw data is unprocessed, which may include a mix of structured and unstructured elements. Thus, structured data is the ideal choice when discussing formats that are regular and predictable.
