Entity-relationship (E-R) data modeling is a highly popular technique for creating a data model. It is a graphical representation of entities and their relationships to each other, which helps in describing the content of a database by defining what is to be stored in the database and the associations among them. UML is more commonly used in software development for designing software systems, and the data integrity model and object-relational model are specific types of data models that are not as widely used as the E-R model.
