The remaining three chapters in this part address distinct aspects of parallel and distributed databases, with chapter 21 covering storage and indexing, chapter 22 covering query processing, and chapter 23 cov ering transaction management. We could choose to store students tuples in a heap file, with a clustered index on the sname field. alternatively, we could choose to store it with an index on the gpa field, or to create indexes on both fields, or to store it as a file sorted by gpa. We provide the solutions to the practice exercises of the seventh edition of database system concepts , by silberschatz, korth and sudarshan. these practice exercises are different from the exercises provided in the text. Sparse index: index entries only for some of the record in the data file. typically, one entry per block of the data file. primary index: determines the location of data file records, i.e. order of index entries same as order of data records. secondary index does not determine data location.
