{"Image DocumentName": "B-Tree Index Files (Cont.)", "Image ImageDescription": "Advantages of B-Tree indices: May use less tree nodes than a corresponding B+-Tree. Sometimes possible to find search-key value before reaching leaf node. Disadvantages of B-Tree indices: Only small fraction of all search-key values are found early. Non-leaf nodes are larger, so fan-out is reduced. Thus B-Trees typically have greater depth than corresponding B+-Tree. Insertion and deletion more complicated than in B+-Trees. Implementation is harder than B+-Trees. Typically, advantages of B-Trees do not out weigh disadvantages.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
