- In a B^ tree, data pointers are stored only at the leaf nodes of the tree. This means that the actual data values or records are stored only in the leaf nodes, while the internal nodes of the tree contain keys that are used for navigation and indexing purposes.
- The leaf nodes of a B^ tree are usually linked together to provide ordered access on the search field to the record. This means that the leaf nodes are arranged in a linked list fashion, allowing for efficient sequential access to the records based on the search key or field. This ordered access is beneficial for range queries and other operations that require accessing records in a specific order.
- Each internal node in a B^ tree has almost p tree pointers. The number of tree pointers in an internal node is typically one less than the number of keys stored in that node. This ensures that there is a pointer to each child subtree for efficient navigation and searching within the tree structure.
- Therefore, all of the above statements are true for a B^ tree. The B^ tree data structure is designed to provide efficient indexing and searching capabilities, especially for large datasets. By storing data pointers only at the leaf nodes, linking the leaf nodes for ordered access, and maintaining a specific number of pointers in each internal node, B^ trees can efficiently handle insertions, deletions, and searches in logarithmic time complexity.
