Enterprise Data Dictionary and Data Syntax Rules

Maintain an enterprise data dictionary that incorporates the organisation’s data syntax rules. This dictionary should enable the sharing of data elements amongst applications and systems, promote a common understanding of data amongst IT and business users, and prevent incompatible data elements from being created.

  • Ineffective application controls

Hide Control Practices  help

  1. Ensure that a data dictionary exists that is used to control and co-ordinate definitions and usage of reliable and relevant data consistent with the enterprise information model.
  2. Establish and maintain data syntax guidelines that are valid throughout the organisation.
  3. Verify the effectiveness of the enterprise data dictionary by identifying reductions in data redundancy and data incompatibility throughout the organisation.
  4. Ensure that the business and IT agree upon data syntax rules, data validation rules and business rules.
  5. Ensure that metadata in a data dictionary are sufficiently detailed to communicate syntax in an integrated manner across applications.
  6. Implement data dictionary management software to manage and maintain the organisation’s data dictionary and data syntax rules.
  7. Implement a data quality programme to increase data integrity, standardisation, consistency, one-time data entry and storage, and to reduce flaws.

Can anyone provide guidance or reference to best practice regarding publishing of data dictionaries (e.g on a common network drive, intranet site open to public etc)  and security levels required? Thanks
