Data Custodian

Data Custodians oversee the safe transport and storage of data. While content is important to them, their focus is on the underlying infrastructure and activities required to keep the data intact and available to users. They collaborate with the Data Stewards to implement data transformations, resolve data issues, and collaborate on system changes.

A data custodian ensures:

  • Access to the data is authorized and controlled
  • Data stewards are identified for each data set
  • Technical processes sustain data integrity
  • Processes exist for data quality issue resolution in partnership with Data Stewards
  • Technical controls safeguard data
  • Data added to data sets are consistent with the common data model
  • Versions of Master Data are maintained along with the history of changes
  • Change management practices are applied in maintenance of the database
  • Data content and changes can be audited
