   RIDKeyPair | Structure to store a key-rid pair. It is used to pass the pair to functions that add to or make changes to the leaf node pages of the tree. Is templated for the key member |
| PageKeyPair | Structure to store a key page pair which is used to pass the key and page to functions that make any modifications to the non leaf pages of the tree |
| IndexMetaInfo | The meta page, which holds metadata for Index file, is always first page of the btree index file and is cast to the following structure to store or retrieve information from it.

Root page starts as page 2 but since a split can occur at the root the root page may get moved up and get a new page no |

| LeafNodeDouble | Structure for all leaf nodes when the key is of DOUBLE type |
| LeafNodeString | Structure for all leaf nodes when the key is of STRING type |
