Data quality
More than fifty rules look for contradictions and show them before the record leaves for the register or a document.
The rules check meaning rather than form: a sire younger than its offspring, an insemination earlier than the calving, offspring that do not agree with the birth type, a breed percentage outside the possible range. Errors of this kind are not caught by making a field mandatory — they arise between fields.
Findings are shown where they can be corrected, and before submission. A rejection from the state register arrives a week later and does not say which row is at fault; our check names the animal and the field.
| RU 4512 087 | Sire younger than progeny | pedigree |
| RU 4512 130 | Insemination before calving | events |
| RU 4511 902 | Calf count does not match the birth type | calving |
A finding does not block the work: the rule can be wrong in a rare case, and the decision stays with the person.
A finding names the animal and the field — otherwise it cannot be fixed. A rejection from the register arrives a week later and talks about the file.
Limits
- A rule can be wrong in a rare case — an animal really can be unusual. So a finding does not block the work; it asks for a human decision and stays visible.
