Understanding DDE, DDW, and EDW: Key Data Exchange Protocols in SCADA Systems

Dynamic Data Exchange (DDE)

DDE is a data and message exchange protocol that allows applications to communicate data and messages.

DDE in SCADA can provide real-time data interchange and integration by facilitating communication between multiple software components or systems.

DDE (Dynamic Data Exchange) is an outdated communication protocol used in SCADA to send data between applications. It enables applications to communicate information and commands.

Data Distribution within a Wide Area Network (DDW)

In a SCADA system, this word often refers to data delivery over a wide area network.

It includes techniques and technology for efficiently transmitting and managing data across geographically scattered locations, while also ensuring accurate and timely data dissemination.

Enterprise Data Warehouse (EDW)

An Enterprise Data Warehouse in the context of SCADA could act as a centralized repository for preserving historical data acquired from numerous SCADA systems throughout a company’s operations.

By combining data from several SCADA sources into a single complete database, it provides a structure for analysis, reporting, & decision-making. This centralized storage improves data accessibility while also allowing for long-term trend monitoring and performance evaluation.

An EDW may be used in the SCADA context to combine and analyze SCADA data with data from other across the organization data sources to provide thorough insights and decision-making.

Each of these components is important in improving the functionality, efficiency, & reliability of SCADA systems by properly handling data interchange, dissemination, and storage across multiple levels of the infrastructure.
