With a +programming interface that is very similar to LDAP, ldb can store its +data either in a tdb(3) database or in a real LDAP database. + </para> + + <para> +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. + </para> + + <para> +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. + </para> + + <para> +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. + </para> + + <para> +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. + </para> + + <para> +If you are new to ldb, then I suggest starting with the manual pages +for ldbsearch(1) and ldbedit(1), and experimenting with a local +database. Then I suggest you look at the ldb_connect(3) and +ldb_search(3) manual pages. + </para> +</refsect1> + +<refsect1> + <title>TOOLS</title> + + <itemizedlist> + <listitem><para> + <application>ldbsearch(1)</application> + - command line ldb search utility + </para></listitem> + + <listitem><para> + <application>ldbedit(1)</application> + - edit all or part of a ldb database using your favourite editor + </para></listitem> + + <listitem><para> + <application>ldbadd(1)</application> + - add records to a ldb database using LDIF formatted input + </para></listitem> + + <listitem><para> + <application>ldbdel(1)</application> + - delete records from a ldb database + </para></listitem> + + <listitem><para> + <application>ldbmodify(1)</application> + - modify records in a ldb database using LDIF formatted input + </para></listitem> + </itemizedlist> +</refsect1> + +<refsect1> + <title>FUNCTIONS</title> + + <itemizedlist> + <listitem><para> + <function>ldb_connect(3)</function> + - connect to a ldb backend + </para></listitem> + + <listitem><para> + <function>ldb_search(3)</function> + - perform a database search + </para></listitem> + + <listitem><para> + <function>ldb_add(3)</function> + - add a record to the database + </para></listitem> + + <listitem><para> + <function>ldb_delete(3)</function> + - delete a record from the database + </para></listitem> + + <listitem><para> + <function>ldb_modify(3)</function> + - modify a record in the database + </para></listitem> + + <listitem><para> + <function>ldb_errstring(3)</function> + - retrieve extended error information from the last operation + </para></listitem> + + <listitem><para> + <function>ldb_ldif_write(3)</function> + - write a LDIF formatted message + </para></listitem> + + <listitem><para> + <function>ldb_ldif_write_file(3)</function> + - write a LDIF formatted message to a file + </para></listitem> + + <listitem><para> + <function>ldb_ldif_read(3)</function> + - read a LDIF formatted message + </para></listitem> + + <listitem><para> + <function>ldb_ldif_read_free(3)</function> + - free the result of a ldb_ldif_read() + </para></listitem> + + <listitem><para> + <function>ldb_ldif_read_file(3)</function> + - read a LDIF message from a file + </para></listitem> + + <listitem><para> + <function>ldb_ldif_read_string(3)</function> + - read a LDIF message from a string + </para></listitem> + + <listitem><para> + <function>ldb_msg_find_element(3)</function> + - find an element in a ldb_message + </para></listitem> + + <listitem><para> + <function>ldb_val_equal_exact(3)</function> + - compare two ldb_val structures + </para></listitem> + + <listitem><para> + <function>ldb_msg_find_val(3)</function> + - find an element by value + </para></listitem> + + <listitem><para> + <function>ldb_msg_add_empty(3)</function> + - add an empty message element to a ldb_message + </para></listitem> + + + <listitem><para> + <function>ldb_msg_add(3)</function> + - add a non-empty message element to a ldb_message + </para></listitem> + + + <listitem><para> + <function>ldb_msg_element_compare(3)</function> + - compare two ldb_message_element structures + </para></listitem> + + + <listitem><para> + <function>ldb_msg_find_int(3)</function> + - return an integer value from a ldb_message + </para></listitem> + + + <listitem><para> + <function>ldb_msg_find_uint(3)</function> + - return an unsigned integer value from a ldb_message + </para></listitem> + + + <listitem><para> + <function>ldb_msg_find_double(3)</function> + - return a double value from a ldb_message + </para></listitem> + + + <listitem><para> + <function>ldb_msg_find_string(3)</function> + - return a string value from a ldb_message + </para></listitem> + + + <listitem><para> + <function>ldb_set_alloc(3)</function> + - set the memory allocation function to be used by ldb + </para></listitem> + + + <listitem><para> + <function>ldb_set_debug(3)</function> + - set a debug handler to be used by ldb + </para></listitem> + + + <listitem><para> + <function>ldb_set_debug_stderr(3)</function> + - set a debug handler for stderr output + </para></listitem> + </itemizedlist> +</refsect1> + +<refsect1> + <title>Author</title> + + <para> + ldb was written by + <ulink url="http://samba.org/~tridge/">Andrew Tridgell</ulink>. + </para> + + <para> +If you wish to report a problem or make a suggestion then please see +the <ulink url="http://ldb.samba.org/"/> web site for +current contact and maintainer information. + </para> + + <para> +ldb is released under the GNU Lesser General Public License version 2 +or later.
