Which one of the following statements is NOT correct about the B+ tree...
Non-Leaf Nodes Have Pointers to Data Records:
One of the statements that is NOT correct about the B+ tree data structure used for creating an index of a relational database table is that non-leaf nodes have pointers to data records. Below is an explanation of why this statement is incorrect:
Key Points:
- In a B+ tree, non-leaf nodes contain pointers to other nodes, not to actual data records.
- The purpose of non-leaf nodes in a B+ tree is to guide the search for a specific key value to the appropriate leaf node.
- Leaf nodes, on the other hand, contain key values along with pointers to the actual data records in the database table.
- By keeping data records only in the leaf nodes, B+ trees ensure that all data retrieval operations involve searching through a relatively small number of nodes, improving the overall efficiency of the index structure.
Therefore, the correct statement should be that non-leaf nodes in a B+ tree have pointers to other nodes, not to actual data records.
