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
A sorted file has the following details: Number of records = 13,10,720;
record length = 200 bytes; size of the primary key field = 13 bytes; size
of block pointer = 7 bytes; block size = 2048 bytes. For this file, we
need to build a multi-level index on the primary key.
The number of blocks in the first level index file is
Insertion of a new record operation is the most efficient for which file organization?
a) ordered
b) unordered
c) hashed
