Implement the dictionary ADT of Section 4.4 for a large file stored on disk by means of the B+-tree of Section 10.5. Assume that disk blocks are 1024 bytes, and thus both leaf nodes and internal nodes are also 1024 bytes. Records should store a 4-byte (int) key value and a 60-byte data field. Internal nodes should store key value/pointer pairs where the "pointer" is actually the block number on disk for the child node. Both internal nodes and leaf nodes will need room to store various information such as a count of the records stored on that node, and a pointer to the next node on that level Thus, leaf nodes will store 15 records, and internal nodes will have room to store about 120 to 125 children depending on how you implement them. Use a buffer pool (Section 8.3) to manage access to the nodes stored on disk.
