An entity relationship diagram (ERD) is a visual illustration of the entities, types of relationships, and key attributes of a construction company. It helps to gain an understanding of how the different parts of the company work together and how they may be connected to external stakeholders. An ERD shows the main entities, which are then broken down into sub-entities representing smaller parts of the system in more detail. The various relationships between these entities are represented using arrows that denote “belongs to” or “contains” type relationships. This information can then be used in creating software or other applications that need to access data from within the company. Use EdrawMax to create and download an ERD for the construction of a classroom for your project plans.
