Distribution Management System
SGD uses an object-oriented technology and integrated architecture having an interface
with customer information system.
Version Management
CERJ´S SGD uses Smallworld´s Version Management tools to coordinate updates to
database by multiple users in each district. Activities such as design and planning that
depend on it often require several different scenarios to be handled at the same time. A
specific application groups together the changes an individual user makes to the
database during a given activity, however long it takes. No other user is affected by
these changes until the activity is completed and they are automatically reconciled to the
authoritative master database. The result is that each user has access to its own private
version, without risk of data integrity. Two users can work safely with the same area of
the database.
Data Maintenance
Once data capture has been finished the greater challenge is the database maintenance.
CERJ has developed a Data Maintenance Plan basically composed by:
-
Definition of procedures to guarantee the database update
-
Periodic audits in the district offices to verify the procedures accomplishment
-
Implementation of data quality indices
Electric Network and Cartographic Information Module
CERJ´s SGD provides a customized database maintenance environment for users
throughout the organization while maintaining information in a common database
accessible to all employees through location queries.
This environment provides functions, via an user-friendly and point-and-click interface,
to edit and query objects for both cartographic and electric network information.
Object Editors
Through tools editor, called Object Editor, users are able to edit both the geometry and
text attributes of an object. Figures 2 and 3 show examples of TRANSFORMERS and
STREETS editions.
