Berkeley DB is a database library, in which the library is linked into the address space of the
|
|
|
|
|
|
application using it. One or more applications link the Berkeley DB library
|
|
|
|
|
|
directly into their address spaces. There may be many threads of control in this model because
|
|
|
|
|
|
Berkeley DB supports locking for both multiple processes and for multiple threads within a
|
|
|
|
|
|
process. This model provides significantly faster access to the database functionality, but
|
|
|
|
|
|
implies trust among all threads of control sharing the database environment because they will
|
|
|
|
|
|
have the ability to read, write and potentially corrupt each other's data.
