= Purpose =
The purpose of the [[mhttpd]] ODB page is to allow the user to browse, search and edit the ODB of an experiment.  
This gives a graphical alternative to using the ODB editor [[odbedit]].
 
= Access the ODB page =
The ODB Page is accessed from the [[Status Page]] (or any of the other Pages) by clicking on the menu-button
<span style="color: #444444; background-color: #CCCCCC; font-style:italic; font-size: 90; padding:0.25em;
padding-left: 0.5em;padding-right: 0.5em;border:1px solid #808080;border-radius: 5px;margin-bottom:1px;">ODB</span>.
The top level ODB trees will be visible as links ([[#Example ODB Page|Figure 1]]).

= Browse the ODB =
By clicking on the links on the ODB page (e.g. [[#Example ODB Page|Figure 1]]), the user can browse the various subtrees. By clicking on the "+" link adjacent to the "Value" heading ([[#Figure 2|Figure 2]]) , the type and size of the keys are shown. This is equivalent to the [[odbedit]] commands "ls" and "ls -l".
