1.	Explain How Dangling Tuples May Arise. Explain Problems That They May Cause?
Answer» Dangling tuples can ARISE when one tuple is inserted into a decomposed relation but no corresponding tuple is inserted into the other relations in the decomposition. They can CAUSE incorrect values to be returned by QUERIES which form the join of a decomposed relation since the dangling tuple might not be included. dangling tuples can be AVOIDED by the specification of referential integrity constraints. Dangling tuples can arise when one tuple is inserted into a decomposed relation but no corresponding tuple is inserted into the other relations in the decomposition. They can cause incorrect values to be returned by queries which form the join of a decomposed relation since the dangling tuple might not be included. dangling tuples can be avoided by the specification of referential integrity constraints.
