## Glossary

Certain acronyms, abbreviations, and technical terms are used throughout this document and are defined in the table below.

Term | Description
--- | ---
Application Server | Computer in a distributed PME system that is running all of the PME applications and services. See “Distributed System” for more details.
Database Server | A computer in a distributed PME system that is running the SQL database server software and the PME databases. See “Distributed System” for more details.
DB | Database (e.g., ION_Data).
DC | Data Center
Device | A meter or a point of data collection.
Distributed System | A PME installation where parts of the system are installed on different computers. Several combinations are possible, but the most common is the separation of the PME applications and the Database server onto different computers. For example, a simple distributed install would have all the PME relevant programs and services installed on one computer and SQL Server with the PME databases installed on a second computer. In this case, the computer running the applications is called the Application Server, and the computer running SQL Server is called the Database Server. A distributed system can also have Web client computers that run Web browsers to view the PME Web applications such as Dashboards, Tables, Alarm Viewer, and Reports inside the Web framework.
Download able Devices | Standard Edition (SE) – Full support including logs etc; may be released as an installer but will become native in the subsequent release of PME. Limited Edition (LE) – Only real-time and PC based logging; created and supported by Schneider Electric; will never become native. Custom Edition (CE) – Only real-time and PC based logging; created by Schneider Electric or 3rd party. CEs are used on an as-is basis; they were previously referred to as L2 or Jenny Type device drivers. SE and LE drivers are available in the download area and can be released as dPacks. CE drivers are available on the Marketplace as-is.
ENM | Event Notification Module
HC | Healthcare
IIS | Internet Information Services
OS | Operating System
PME | Power Monitoring Expert
SSDT | SQL Server Data Tools
SSMS | SQL Server Management Studio
Standalone Server | A single computer running all parts of a PME system. See “Standalone System” for more details.
Standalone System | A PME installation where all parts of the system are installed on the same computer, i.e., all applications and services, the SQL database server, and the databases are on a single computer. This single computer is then referred to as Standalone Server. A standalone system can also have Web client computers which are running Web browsers to view the PME Web applications like Dashboard, Tables, Alarm Viewer, and Reports inside the Web framework. Configuration Manager supports standalone systems.
VM | Virtual Machine (as compared to a physical computer).
Web Client | A computer in a PME system that runs a Web browser to view the Web applications like Dashboard, Tables, Alarm Viewer, and Reports inside the Web framework. Both standalone and distributed PME systems can have Web clients.
