mastertietolähde

Mastertietolähde is a term used in information management and data governance to refer to the definitive and authoritative source of truth for a specific piece of data within an organization. It is the designated system, database, or repository where the most accurate, up-to-date, and complete information resides. Identifying and maintaining master data sources is crucial for ensuring data consistency, reducing errors, and enabling reliable decision-making.

The concept of a master data source emphasizes that for any given data element, such as a customer name, product ID, or employee record, there should only be one primary location where it is managed and updated. Other systems or applications that require this data should then derive it from this master source, rather than maintaining their own separate, potentially conflicting versions. This approach helps to avoid data duplication and discrepancies that can arise when data is managed in silos.

Establishing a master data source typically involves defining clear ownership, governance processes, and data quality standards. It requires careful analysis of existing data systems to determine which one best serves as the authoritative source. The goal is to create a single, trusted view of key business entities, thereby improving operational efficiency and strategic insight.
