The architecture of open source applications-Berkeley DB
1. it is vital for any complex software package's testing and maintenance that the software must be designed and built as a cooperating set of modules with well-defined API boundaries. the boundaries can (and shocould !) Shift as needs dictate, but they always need to be there. the existence of those boundaries prevents the software from becoming an unmaintainable pile of spaghetti. butler Lamps

BSDDB module is used to operate the BDB module, BDB is the famous Berkeley DB, its performance is very good, MySQL's storage back-end engine support BDB way. Here is a brief introduction to some of the ways in which BSDDB is used.
Unlike a general relational database, BDB stores only a pair of data that consists of key and value, which, like a Python dictionary, cannot directly represent multiple fields, a
Berkeley dB, produced by sleepycat software, is a database system that is widely used in specific data management applications and supports more than 0.2 billion of users worldwide. many world-renowned vendors, such as Amazon, AOL, British Telecom, Cisco Systems, EMC, Ericsson, Google, Hitachi, HP, Motorola, RSA Security, Sun Microsystems, both tibco and VERITAS rely on bdb to provide fast, elastic, reliable, and cost-effective data management for man

As an embedded database system with a long history, Berkeley dB is mainly used in Unix/Linux operating systems. Its design philosophy is simple, compact, reliable, and high-performance.
In Java, the performance of Berkeley dB 4.1.6 is three times higher than 4.0. It supports multi-thread management and advanced memory node compression.

Berkeley DB The implementation method of using Secondkey to sort data is the main content of this article, we use the NoSQL database BDB when doing the project, and take this opportunity to study its usage. Its official examples and documents are richer and more easily learned. In the development process, there is a requirement to traverse the data according to the insertion time, which is more easily realized by the second primary key (Secondkey).Her
