What are two examples of semi-structured file types?

1. .json, .html

2. .xml, .txt

3. .json, .xml

4. .csv, .dat

The correct answer is: .json, .xml

Semi-structured file types are those that do not conform to a rigid schema like structured data formats but still contain some organizational properties that make them easier to analyze compared to completely unstructured data. The combination of .json and .xml as examples of semi-structured file types is appropriate because both formats allow for hierarchical data representation while being flexible regarding the structure of data they contain. JSON (JavaScript Object Notation) is often used for data interchange in web applications. It represents data as key-value pairs and is human-readable. XML (eXtensible Markup Language) is another markup language that defines rules for encoding documents in a format that can be read by both humans and machines, allowing for nested data structures. In contrast, while .html files can sometimes contain semi-structured information, they are primarily designed for displaying content on the web, making them more focused on presentation rather than structured data storage. Text files, indicated by .txt formats, are generally considered unstructured because they contain raw text without any defining structure. Formats like .csv and .dat can represent structured data, as they define specific formatting rules for storing tabular data, which doesn't place them in the semi-structured category. The focus on .json and .xml effectively
