  • The use of ER diagrams or Entity-Relationship diagrams ensures easy data interpretation through diagrams and assists in the organizing of data structures conclusively during the creation of databases as well as in the transmission of data to different stakeholders.

    However, when control becomes operant, it can become less manageable in large systems because they require significant coordination, and thus might lead to oversimplification or misinterpretation of cause and effect. Furthermore, it also can consume a lot of time and effort, as well as improper creation and maintenance might need professional help.
