3) Assume we have a file of 16.450.000 records. Each record is of size 250 bytes, 15 of which for the field key..Blocks are of size 2048 bytes. A block pointer is of size 5 bytes. We use a B-tree organization where both blocks of the main and index file are filled to the minimum. - Compute: total number of blocks for the main file total number of block for the index file max number of block accesses to find a record in the main file
