Berkeley DB

Database Management System

Berkeley DB (BDB) is an embedded database software library for key/value data, historically significant in open-source software. It is a C-based embedded database designed for storing key/value pairs, supporting multiple data entries per key, and includes features like transactions, multiversion concurrency control, and write-ahead logging. Though not relational in structure, it functions across diverse platforms including Unix-like systems, Windows, and real-time operating systems.

FAQs

How does an application use Berkeley DB?

It links directly into the application as a library and runs in the same address space.

Berkeley DB is an embedded database library, so it links directly into the application and runs in the same address space. No inter-process communication is needed for database operations. It offers a function-call API for several programming languages, including C, C++, Java, Perl, Tcl, Python and PHP, and low-level services such as locking and transaction logging are handled inside the library.
