adattár

Adattár is a Hungarian term referring to a repository or store of data. It denotes a centralized collection of data drawn from diverse sources within an organization, designed for storage, preservation, search, retrieval, and analysis. An adattár may operate at various scales, from a departmental data store to an organization-wide data repository.

Etymology: The word comes from adat (data) and tár (store, collection). In information technology usage, adattár is often used interchangeably with terms such as adatbázis (database) or adatraktár (data warehouse). However, distinctions exist: an adattár describes a data repository generally, whereas an adatbázis emphasizes structured, transactional storage and querying, and an adatraktár emphasizes analytics and historical data integration.

Applications and contents: An adattár typically integrates data from multiple sources, accompanied by metadata and data governance rules. It supports data quality management, access control, versioning, and retention policies. Users access the data for reporting, analysis, research, or decision-making. In libraries and archives, adattár may refer to digital collections and preserved records; in business contexts, it serves as a data hub for BI and analytics.

Structure and management: An effective adattár uses metadata schemas, standardized data formats, and interoperable interfaces (for example APIs or query tools). It relies on data governance frameworks to ensure privacy, security, and compliance with legal requirements. Long-term preservation may involve archival strategies and format migration.
