DATABASES
42
Databases
• CYME is a very powerful electrical engineering
analysis software for electrical networks
composed of numerous types of devices.
• To manage all of this data CYME uses complex
database schemes to manage and manipulate this
data
• The calculations used in the analyses of CYME
can be very precise and effective results can be
generated, but the quality of the results relies
mostly on the quality and precision of the
information describing each of its components.
43
Databases
The Network Models section
includes commands and lists
the available database
connections
These are the database connections
The Dynamic Data Push/Pull section
allows the CYME Software to use a
plugin to connect to one or multiple
external enterprise systems to
import/export data
The Profile / Billing section is
also available for users to
create connections to Profile
or Billing databases
independent of any Network
database connection*
The Repository section
will appear only if there
are existing connections
to repository databases.
The Results section
allows you to create a
database repository for
the results generated by
the analyses you will run.
*available when a valid license of the CYME Steady State Analysis with Load Profiles module is detected.
44

set up to limit the access rights on the
equipment and/or network database.
Advantages
Disadvantages

database administrator
Nothing has to be installed on the
client workstation
High memory usage: the user
have to set limits of memory that
can be used
Ideal for client/server network
architecture – i.e. multiple users
