Metadata

Metadata is commonly described as “data about data”, which is used to describe, structure, and provide context for other information. In IT, system development, and integration, metadata plays a crucial role in enabling understanding, governance, and automated data handling across systems.

Metadata contains information that describes the characteristics of data, such as structure, format, origin, meaning, relationships, and lifecycle. This includes technical metadata like data types and schemas, as well as business metadata covering semantics, ownership, and usage rules.

• Technical metadata: formats, schemas, tables, field types

• Business metadata: definitions, concepts, ownership, rules

• Operational metadata: logs, versioning, timestamps

• Security metadata: classification, access levels, policies

The concept of metadata has long existed in library science and information management, but gained increased importance with the rise of databases, data warehousing, business intelligence, and cloud-based systems.

Within Microsoft platforms, metadata is used to describe data across databases, integration flows, reporting solutions, and information models. Metadata supports automation, traceability, and consistent data governance.

Metadata is a fundamental enabler for structured, understandable, and governable information management in modern IT landscapes.
