Data Custodian

A data custodian is a person or organization responsible for managing and protecting data. They ensure that data is secure and accessible and that it is not altered, destroyed, or used without authorization.

Some of the responsibilities of a data custodian include:

Data security: Managing the security controls and technology around data confidentiality, integrity, and availability

Data access control: Controlling access rights to data

Data governance: Implementing data policies and rules

Data quality management: Ensuring data quality is maintained

Data maintenance: Maintaining the technical environment where data is stored

Data audits: Ensuring changes to data content and controls can be audited

Data recovery: Providing and administering backup and recovery systems

Data custodians are data modelers or ETL (Extract, Transform, Load) developers. They are often responsible for resolving data storage, processing, and usage issues.
