Entity–Relationship Model

Model or diagram describing interrelated things

An entity–relationship model (or ER model ) describes interrelated things of interest in a specific domain of knowledge. A basic ER model is composed of entity types (which classify the things of interest) and specifies relationships that can exist between entities (instances of those entity types).

In software engineering, an ER model is commonly formed to represent things a business needs to remember in order to perform business processes. Consequently, the ER model becomes an abstract data model, that defines a data or information structure which can be implemented in a database, typically a relational database.

Implementation of a Device Failure Query Model for the Virtual Power Plant Smart Operation and Maintenance Platform Based on Retrieval-Augmented Generation Technology
2025
By leveraging retrieval-augmented generation technology in human–computer interaction applications, a large language model was established based on local hardware to construct a root cause query model for equipment failures on virtual power plant intelligent operation and maintenance platforms. This enhances the efficiency of maintenance personnel in retrieving troubleshooting solutions from vast technical documentation. First, the virtual power plant architecture was established, clarifying the functions of each …
