What is the function of a ModelGen operator? A It identifies fundamental conflicts and devises rules for resolving them. B It takes a model in one meta-model and translates it into another meta-model. (C) It transforms the data from one data model to another and applies a schema mapping. D It transforms data from the model and schema in which it is stored into the target message format.

Complex real-world applications call for large volumes of data. Therefore, it is necessary to build a great database to store data safely and coherently. The ER data model aids in the process of database design. It helps outline the structure of an organization’s database by understanding the real-world interactions of objects related to the data. For example, if a school is tasked to store student information, then analyzing the correlation between the students, subjects, and teachers would help identify how the data needs to be stored.
