The Importance of Database Design
... Cycles are another potential problem that can be created in a physical database schema. A cycle is a referential path that connects a table to itself. This can occur when multiple tables are related back to each other and it looks like a loop when diagrammed. DB2 forbids a table from being deletecon ...
