私はこの小さな怪物 php スクリプトを自分用に作成しました。これは、簡略化された txt ファイルから SQL DDL を生成し、履歴テーブルとそのCREATE TRIGGERステートメントを生成できるようになりました。

ソースの例:
// ZZZ means "Create History Table + Triggers"
// you can try editing it live at the link above
!DROP
= ID id P AI
person ZZZ
ID
name _
N mother_id -> person
N father_id -> person
!FK mother_id, father_id -> family
family ZZZ
P female_id -> person
P male_id -> person
結果の SQL DDL:
