Duplikátum

Duplikátum is a Latin term meaning "duplicate" or "copy." It is often used in legal and archival contexts to refer to a copy of an original document or item. The term emphasizes that the duplicate possesses the same validity and legal standing as the original, particularly when it is certified as such. For instance, a certified duplicate of a birth certificate serves the same purpose as the original for official identification.

In data management and computer science, a duplicate refers to an identical or near-identical record or piece of information that exists in multiple locations within a system or across different systems. Identifying and managing duplicates is crucial for maintaining data integrity, preventing redundancy, and optimizing storage and processing efficiency. Duplicate data can arise from various sources, including data entry errors, system integrations, or incomplete data deletion processes. Various algorithms and techniques are employed to detect and resolve duplicates, ranging from simple exact matching to more complex fuzzy matching methods that account for minor variations in the data. The presence of duplicates can lead to inconsistencies, inaccurate reporting, and increased operational costs if not properly addressed.
