Storage Management for Files of Dynamic Records
... There are two difficulties in managing dynamic records on disk. The first is that they vary in length. The second is that each record can change in length over time. We propose a space management scheme in which records are stored in large, fixed-length blocks3 . In this scheme, records are numbered ...

B-tree
In computer science, a B-tree is a tree data structure that keeps data sorted and allows searches, sequential access, insertions, and deletions in logarithmic time. The B-tree is a generalization of a binary search tree in that a node can have more than two children (Comer 1979, p. 123). Unlike self-balancing binary search trees, the B-tree is optimized for systems that read and write large blocks of data. B-trees are a good example of a data structure for external memory. It is commonly used in databases and filesystems.
