Which statement is false?
  • a)
    The leaf nodes of the B+ tree are usually linked together to provide ordered access on the search field to the records.
  • b)
    Most implementations of dynamic multilevel index use a variation of the B tree data structure called as B+ tree.
  • c)
    For a B+ tree constructed on a key, the pointers in internal nodes are tree pointers to blocks that are tree nodes.
  • d)
    In B+ tree, data pointer's are stored in the leaf nodes of the tree and the structure of leaf nodes is same as that of the internal nodes.
Correct answer is option 'D'. Can you explain this answer?

B Tree Structure

B tree is a balanced tree data structure that is used for efficient indexing of large data sets. It is commonly used in database systems and file systems. Here are some statements regarding the B tree structure:

a) The leaf nodes of the B tree are usually linked together to provide ordered access on the search field to the records.
This statement is true. The leaf nodes in a B tree are usually linked together to provide ordered access to the records based on the search field. This allows for efficient range queries and sequential access.

b) Most implementations of dynamic multilevel index use a variation of the B tree data structure called as B tree.
This statement is also true. The B tree data structure is commonly used in dynamic multilevel indexing due to its ability to efficiently handle large data sets and its balanced nature.

c) For a B tree constructed on a key, the pointers in internal nodes are tree pointers to blocks that are tree nodes.
This statement is true. In a B tree constructed on a key, the pointers in internal nodes are tree pointers to blocks that are themselves tree nodes. This allows for efficient traversal of the B tree during searches.

d) In B tree, data pointers are stored in the leaf nodes of the tree and the structure of leaf nodes is same as that of the internal nodes.
This statement is false. In a B tree, data pointers are stored in the leaf nodes of the tree, but the structure of the leaf nodes is different from that of the internal nodes. The internal nodes contain pointers to other nodes in the B tree, while the leaf nodes contain actual data pointers to the records in the data set.
