Dependency Tool
Chaomei Lo, Sutanay Choudhury, Brian Ermold, Todd
Halter, Matt Macduff
Objective
This web-based interface tool is used to
retrieve the information on ARM data
streams and present it in a tree diagram.
Current Status

• User can specify a data stream based on a site
  and a facility name and
• retrieve the following information
• Track all datastreams that are used to create
  this datastream.
• Track all datastreams that use this datastream
  as input.
• Track what type of process created this
  datastream (VAP, INGEST,
• Collection, etc.)
• Track which process (process name) created this
  datastream.

Implementation
CLIENT SIDE DESIGN Adobe flex 2, a rich internet
application (RIA) framework is used to create an
expressive, high performance web browser based
interface. SERVER SIDE DESIGN Java Servlet
technology with Apache Tomcat Servlet container.
DATA SOURCE Retrieved from ARCF DSDB database,
the combination of XML and JSON technologies are
used to serialize the data across the network.
GRAPH LAYOUT Implemented Sugiyamas graph layout
algorithm in Java.
Proposed Future Extensions

• Be integrated with DOD, BODS, DSView and other
  ARM information systems.
• Track if an input datastream is required or
  recommended.
• Track if a datastream is active/inactive, exists,
  and the reason.
• Track which fields in a datastream were used to
  create the next datastream.
• Track which datastreams provide a particular
  field.
• Track priority of multiple input datastreams used
  for the same type of information.
• Track which VAPs not to run when a datastream is
  down.
