Description

The goal of this task is to establish the Update Tracker mechanism in DOMS. The update tracker will provide the following functionality to DOMS 1. Request Entry Pids changed since a given date.

Design

The Update tracker will consist of a number of components.

1. A database, called DB.
2. A JMS client
3. The update tracker service.

The database will have two tables.

1. Entry Pid - Date changed - View Name: Associates each entry pid/view name combo with a changed date
2. Object Pid - Entry Pid - View Name: Associates each pid in DOMS with a entry pid/view name combo.

There are two main flows in the service

1. Update:
   1. JMS client will be notified upon change to an object
   2. The object pid is looked up to a set of entry pid/ view name combos.
   3. Each of these combos is looked up, and the corresponding entry has date changed updated.
   4. If the change was in RELS-EXT:
      1. For each view for the entry object
      2. Request the view from ECM
      3. Update the pid-entry-view table
2. Lookup
   1. Lookup in the first table
