DB Access Methods Sleepycat Software's family of database management products, Berkeley DB, allows developers to choose the most efficient on-disk representation for their data. The different on-disk layouts, or access methods , provide different search and update performance.
Developers can pick the one that best supports their application.
All Berkeley DB access methods are available in all Berkeley DB database management products. Whether you build a standalone database application using Berkeley DB Data Store or a high-performance shared database server using Berkeley DB Transactional Data Store , you can choose from the same set of access methods. Programmers can use any data type that they like, including programming language structures, for either the key or the value part of a record. Berkeley DB uses the operating system's underlying file system for storage. This limit applies to all the Berkeley DB access methods.
