példányazonosítás

Példányazonosítás is a Hungarian term that translates to "instance identification" or "object identification" in English. It refers to the process of uniquely identifying a specific item or instance within a larger collection or system. This concept is fundamental in various fields, including database management, information retrieval, and scientific research.

In database systems, példányazonosítás is often achieved through primary keys. A primary key is a unique identifier for each record in a table, ensuring that each instance of data can be distinguished from others. This prevents duplication and allows for efficient data manipulation and querying.

In the context of information retrieval and digital libraries, példányazonosítás is crucial for managing and locating specific digital objects. This could involve assigning unique identifiers to documents, images, or other digital assets. These identifiers allow users and systems to reliably access and refer to particular instances of information, even if multiple versions or copies exist.

In scientific research, particularly in fields like biology and archaeology, példányazonosítás is essential for tracking and cataloging physical specimens. Each individual organism, fossil, or artifact may be assigned a unique identifier, allowing researchers to meticulously record its provenance, characteristics, and associated data. This systematic approach ensures the integrity and reproducibility of scientific findings. The core principle of példányazonosítás is the establishment of a clear and unambiguous link between an identifier and the specific entity it represents, facilitating organization, retrieval, and analysis.
