| wiscdb::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. Contains the relation name for which the index is created, the byte offset of the key value on which the index is made, the type of the key and the page no of the root page. 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 |

| wiscdb::PageFile | |
| wiscdb::PageHeader | Header metadata in a page |
| wiscdb::PageIterator | Iterator for iterating over the records in a page |
| wiscdb::PageKeyPair< T > | 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 |
| wiscdb::PageNotPinnedException | An exception that is thrown when a page which is expected to be pinned in the buffer pool is found to be not pinned |
| wiscdb::PagePinnedException | An exception that is thrown when a page which is not expected to be pinned in the buffer pool is found to be pinned |
| wiscdb::PageSlot | Slot metadata that tracks where a record is in the data space |
| wiscdb::RawFile | |
| wiscdb::RecordId | Identifier for a record in a page |
| wiscdb::RIDKeyPair< T > | 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 |
| wiscdb::ScanNotInitializedException | An exception that is thrown when a file operation is requested for a filename that doesn't exist |
