Puolijäsennetyt

Puolijäsennellyt is a Finnish term that translates to "semi-structured" in English. It is commonly used in the context of data and information organization to describe data that does not conform to the rigid, predefined structure of relational databases but still possesses some organizational properties. Unlike unstructured data, which has no inherent organization, semi-structured data contains tags or markers to separate semantic elements and enforce hierarchies.

Examples of semi-structured data include Extensible Markup Language (XML) and JavaScript Object Notation (JSON) files. These formats allow for flexibility in how data is arranged while still providing a framework for parsers and applications to understand the relationships between different pieces of information. This makes them well-suited for situations where the data schema might evolve or where data from various sources needs to be integrated.

The ability to represent complex relationships and hierarchical structures makes semi-structured data valuable in many applications, such as web services, configuration files, and data exchange formats. It bridges the gap between highly structured relational databases and completely unstructured text or media, offering a balance of organization and adaptability.
