A relationship describes an association among entities. You can change physical model without affecting internal model. row on Table B. It does not store or enforce relationship among entities. Physical independence is a condition in which the physical model can be changed without affecting the internal model. Rows are tuples, and columns are attributes. Each relation (table) is conceptually represented as two-dimensional structure of intersecting rows and columns. What is physical independence? Policy makers Ans: A relational database is a single facts repository that provides each structural and information The entity relationship model is easier to examine structures graphically than to describe them in text, database designers prefer to use a graphical tool in which entities and their relationships are pictured.
