Description: Although there has been a lot of AVL tree libraries available now, nearly all of them are meant to work in the random access memory(RAM). Some of them do provide some mechanism for dumping the whole tree into a file and loading it back to the memory in order to make data in that tree persistent. It serves well when there s just small amount of data. When the tree is somewhat bigger, the dumping/loading process could take a lengthy time and makes your mission-critical program less efficient. How about an AVL tree that can directly use the disk for data storage ? If there s something like that, we won t need to read through the whole tree in order to pick up just a little bit imformation(a node), but read only the sectors that are neccssary for locating a certain node and the sectors in which that node lies. This is my initial motivation for writing a storage-media independent AVL Tree. However, as you step forth, you would find that it not only works fine with disks but also fine with memorys, too.-Although there has been a lot of AVL tree libraries available now, nearly all of them are meant to work in the random access memory(RAM).

Description: This project attempts to implement a Database using B+Tree. The project has developed a DATABASE SYSTEM with lesser memory consumption. Its API includes simple SQL Statements and the output is displayed on the screen. Certain applications for which several features of existing databases like concurrency control, transaction management, security features are not enabled. B+Trees can be used as an index for factor access to the data. Help facility is provided to know the syntax of SQL Statements.

Description: 红黑树是一种自平衡二叉查找树,是在计算机科学中用到的一种数据结构,典型的用途是实现关联数组。-AVL trees are actually easier to implement than RB trees because there are fewer cases. And AVL trees require O(1) rotations on an insertion, whereas red-black trees require O(lg n).
In practice, the speed of AVL trees versus red-black trees will depend on the data that you re inserting. If your data is well distributed, so that an unbalanced binary tree would generally be acceptable (i.e. roughly in random order), but you want to handle bad cases anyway, then red-black trees will be faster because they do less unnecessary rebalancing of already acceptable data.On the other hand, if a pathological insertion order (e.g. increasing order of key) is common, then AVL trees will be faster, because the stricter balancing rule will reduce the tree s height.
Splay trees might be even faster than either RB or AVL trees,depending on your data access distribution. And if you can use a hash instead of a tree, then that ll be fastest of all.
