DESCRIPTION

ldb is a light weight embedded database library and API. With a programming interface that is very similar to LDAP, ldb can store its data either in a Boot Country Black Hunting Men's Mossy 400g Shadow Browning Buck Oak 8" OUz6P(3) database or in a real LDAP database.

When used with the tdb backend ldb does not require any database daemon. Instead, ldb function calls are processed immediately by the ldb library, which does IO directly on the database, while allowing multiple readers/writers using operating system byte range locks. This leads to an API with very low overheads, often resulting in speeds of more than 10x what can be achieved with a more traditional LDAP architecture.

In a taxonomy of databases ldb would sit half way between key/value pair databases (such as berkley db or tdb) and a full LDAP database. With a structured attribute oriented API like LDAP and good indexing capabilities, ldb can be used for quite sophisticated applications that need a light weight database, without the administrative overhead of a full LDAP installation.

Included with ldb are a number of useful command line tools for manipulating a ldb database. These tools are similar in style to the equivalent ldap command line tools.

In its default mode of operation with a tdb backend, ldb can also be seen as a "schema-less LDAP". By default ldb does not require a schema, which greatly reduces the complexity of getting started with ldb databases. As the complexity of you application grows you can take advantage of some of the optional schema-like attributes that ldb offers, or you can migrate to using the full LDAP api while keeping your exiting ldb code.

If you are new to ldb, then I suggest starting with the manual pages for ldbsearch(1) and black Pumps pat Women's Kelda Clarks Hope IRn64wIP(1), and experimenting with a local database. Then I suggest you look at the ldb_connect(3) and ldb_search(3) manual pages.
