Implementing Business Requirements in RDM: Choosing the Right Validation Mechanism
Β In large RDM implementations containing dozens of datasets and hundreds of business rules, choosing the appropriate Ataccama RDM capability improves consistency, reduces implementation effort, and makes solutions easier to maintain.Β Selecting the Right Validation MechanismΒ The first design decision is not how to write a validation, but which Ataccama RDM capability is best suited to implement the business requirement.Β Using Dataset ConfigurationΒ RequiredUse the Required property for mandatory attributes instead of validation expressions such as: column is not nullΒ GeneratedUse the Generated property for business key attributes that should remain unchanged after record creation.Β Β Using Custom Data Types (Domains)Β Reusable attribute constraints should be implemented as Project Data Types (Domains) rather than duplicating the same validation logic across multiple datasets.Β Β Typical examples include:Requirement Domain Example Configuration Data type Integer, Long, Float, B
