Data Management

← Back to Domain-Specific Abstractions by Domain

3 domain-specific abstractions whose origin domain is Data Management.

• Bitemporal modeling — Record each fact along both valid time—when it holds in the modeled world—and transaction or system time—when the database records it—so corrections preserve what was believed earlier while enabling as-of knowledge and as-of reality queries.
• Data architect — A data-management role responsible for designing and governing the organization-wide structures, standards, flows, models, and platforms through which data is created, integrated, stored, secured, and used.
• Data cleansing — The governed detection, diagnosis and correction, standardization, quarantine or removal of data defects so records satisfy declared quality rules while preserving provenance and uncertainty.
