Link modules, linksets, and linkset pairings
Link modules store information about standard Rational DOORS links.
Within each link module, the information is subdivided into linksets.
Each linkset contains information about the links from one particular
module to another. External links are not stored in link modules.
Automatic link discovery
When you configure Rational DOORS to use OSLC to integrate
with a remote server, and Rational DOORS uses link discovery to determine
whether there are links to the remote server, you can determine whether
link discovery is performed automatically or decided by individual
users.
Links and traceability
Links give you traceability, so you can check that what
you are building satisfies your user requirements. Links also allow
you to manage change. You can quickly find out what impact a change
has on your project.
Tracking changes to Rational DOORS data
Use history records and links to track changes to data,
and manage the impact that changes have to other items in the database.
Baselines
A baseline is a read-only version of a module. It captures a moment in time and preserves it until you delete the module.
Baseline set definitions and baseline sets
A baseline set definition is a list of the modules that you want to treat as a unit for project planning and project management purposes. The definition can include modules from any project or folder in the database. From the definition, you can create a baseline set for each phase of the project. A baseline set gives a snapshot of the data in the modules and the links that existed between them when the baseline set was closed.
Electronic signatures
Electronic signatures are used with module baselines to provide a secure way of reviewing and signing information at various stages of the development process. A history of the users who have reviewed and signed the document, including timestamps and detailed information about access rights is stored with the baseline. Users cannot change any part of their signature after it has been submitted.
The change proposal system
Managing changes to requirements is a major challenge for any organization. As your projects proceed, it is inevitable that you will need to change requirements. Any changes, however, are bound to affect other requirements; a single change to one requirement can cause a cascade of potential changes to requirements throughout your system. Use the change proposal system (CPS) to manage changes to the requirements in your system.
