Consider the two internal organizations for
heap files (using lists of pages and a directory
of pages) discussed in the text.
1. Describe them briefly and explain the
trade-offs. Which organization would you
choose if records are variable in length?
2. Can you suggest a single page format to
implement both internal file organizations?
Consider a file of 16384 records. Each record is 32 bytes long and its key field is of size 6 bytes. The file is ordered on a non-key field, and the file organization is unspanned. The file is stored in a file system with block size 1024 bytes, and the size of a block pointer is 10 bytes. If the secondary index is built on the key field of the file, and a multilevel index scheme is used to store the secondary index, the number of first-level and second-level blocks in the multilevel index are respectively
Compute total no of blocks}
Consider a file of 8192 records. Each record is 16 bytes long and its key field
Is of size 6 bytes. The file is ordered on a key field, and the file organization
is unspanned. The file is stored in a file system with block size 512 bytes, and
the size of a block pointer is 10 bytes. If the primary index is built on the key
field of the file, and a multilevel index scheme is used to store the primary index,
number of first-level and second level blocks in the multilovel index are
