The database tags interact with SQL databases or LDAP directories.
They can input/output information used in creating everything from
simple tables or forms, interactive graphical reports to complete web
applications.
The LDAP directory tag <ldap> interacts with
LDAP directories as well as LDAP accessible directories like Novell
NDS or Microsoft Active Directory.
The database tags are almost always combined with other RXML tags.
Together with for instance <vform>, the
<sqlquery> tag can be used to put data collected from
the form into a database.
<sqltable> together with <diagram> provides real-time diagrams and
with <tablify> nice looking tables can be
dynamically generated.
The <emit> plugins <emit sql> or <emit ldap> can also be used to search
and list information from a SQl database or LDAP directory.
Each database tag needs to know which database it should connect
to. This is specified by the host-attribute which usually
is a symbolic name for the database that the administrator has
configured in the SQL
Databases module. It is also possible to specify the database
host, user and password directly in the tags, but this is not
recommended.
