secondary key field

1.Define the following terms: indexing field, primary key field, clustering field, secondary key field, block anchor, dense index, and non-dense (sparse) index.

2.What are the differences among primary, secondary, and clustering indexes? How do these differences affect the ways in which these indexes are implemented? Which of the indexes are dense, and which are not?

3.Why can we have at most one primary or clustering index on a file, but several secondary indexes?
