duplikaadid

Duplikaadid is the Estonian term for duplicates or copies. The singular form duplikaat is a loanword derived from German Duplikat, meaning a copy or replica. In everyday and technical language, duplikaadid are used to refer to items that reproduce an original object, document, or data, either exactly or closely.

In information technology and data management, duplikaadid describe multiple records that contain the same or very similar information. Duplicate detection aims to identify and remove or consolidate duplicates to improve data quality and save storage space. Methods include exact matching on key fields, hashing or fingerprinting, and fuzzy or near-duplicate matching to catch close similarities. Deduplication can occur within a single database or across multiple data sets, and it often balances accuracy with processing cost.

In offices, archives, and administration, duplikaadid commonly refer to copies of documents such as invoices, certificates, or forms. Regulations may specify when copies are acceptable and when originals must be preserved, with procedures for verifying authenticity and preventing misuse of duplicates.

In other contexts, duplikaadid can also denote physical replicas, such as prints or models, or biological clones that are genetically identical. The concept generally emphasizes an alternative that is not the original but closely resembles or matches it.
