=== Domain.xml Definition Node ===
>From my understanding, the definition section sets where all the data concerning
>different parts of Slide will be stored.
In the example all sub-stores (lock, content, etc...) are stored using
"org.apache.slide.store.txfile.TxXMLFileDescriptorsStore", which
essentially stores data in an XML formatted file.

==== Reference ====
{{{
<securitystore>
<reference store="nodestore"/>
</securitystore>
}}}
"The reference means that for the security store the same object is used as is, is
configured at the node store." To get a better understanding compare the default
nodestore definition (above) and the nodestore definition using JDBC. The default
nodestore stores all of its data in XML format text files while the nodestore below
stores the data in predefined tables.
==== Definition Using JDBC ====
Ofcourse, for ease of maintenance most people will probably want to use a database to
store most of the data related to Slide. In the example below,
most sub-stores (except content) are using the JDBC configured nodestore.
Note
If you want to try a JDBC nodestore you also have to create all the necessary tables
and views that Slide expects. You can use the scripts (configured for most major
database servers) found in jakarta-slide-2.1b2-tomcat-5.0.28/webapps/slide/db-schema/
(for 2.1b2).
