The software is distributed in source code form, and developers can +compile and link the source code into a single library for inclusion +directly in their applications. + +Developers may choose to store data in any of several different storage +structures to satisfy the requirements of a particular application. In +database terminology, these storage structures and the code that operates on +them are called access methods. The library includes support for the +following access methods: + + * B+tree: Stores keys in sorted order, using either a programmer-supplied + ordering function or a default function that does lexicographical + ordering of keys. Applications may perform equality or range searches. + * Hashing: Stores records in a hash table for fast searches based on + strict equality. Extended Linear Hashing modifies the hash function + used by the table as new records are inserted, in order to keep buckets + underfull in the steady state. + * Fixed and Variable-Length Records: Stores fixed- or variable-length + records in sequential order. Record numbers may be immutable or + mutable, i.e., permitting new records to be inserted between existing + records or requiring that new records be added only at the end of the + database. -- cgit v1.2.3
