HP Medical Archive
CMS—Content Management System
While the LDR manages the payload content on the grid, the Content
Management System (CMS) provides the logic. The CMS is a distrib-
uted database that maintains a map of all HP Medical Archive system
content and its associated metadata (such as media type and DICOM-
specific information).
System content is managed by the CMS according to business rules.
The CMS tracks content and manages data duplication to maximize
system and data availability. With multiple distributed CMS nodes,
you are protected against system failures and have constant access to
grid data.
The CMS also manages access to the grid’s data. When a content
request is made, the CMS works with the ADC to determine which is
the most optimal node from which to deliver that content. This ensures
that data is delivered in a timely and optimized manner. Once an LDR
receives approval from the CMS, it releases the content.
An SQL database is used to support queries on the payload metadata.
The CMS maintains this database and responds to queries.
CMS Attributes
The CMS supports a subset of the standard set of service attributes for
state, status, and node information. It excludes the service status
section attributes entirely.
