Data Custodianship

What is Data Custodianship?

Data Custodianship refers to the role or practice of managing data assets within an organization. It involves ensuring data accuracy, preserving data integrity, facilitating secure and authorized access, maintaining data privacy, and complying with relevant regulations.

Functionality and Features

Data custodians are responsible for various tasks including:

Benefits and Use Cases

Data Custodianship offers numerous advantages:

  • Resource-intensive: requires skilled professionals and robust systems
  • Implementation Complexity: managing disparate data sources can be complex
  • Regulatory Compliance: keeping up with evolving data regulations can be challenging

Integration with Data Lakehouse

Data Custodianship plays a crucial role in a data lakehouse environment. The custodial practices ensure secure, reliable, and efficient data flow throughout the data lifecycle. This optimizes data analytics, paving the way for enhanced decision-making.
