The capstone project aims to integrate knowledge and skills learned in the course, implement and enhance competencies emphasized in the fundamental subjects, apply and design skills acquired in the course, accomplish a comprehensive written report in the context of the capstone project for undergraduate studies and future IT professionals. Additionally, entities are also described further using attributes. Example of a recursive relationship in ER diagrams Cardinality and Ordinality These two further defines relationships between entities by placing the relationship in the context of numbers. These are called composite attributes. An Entity Relationship Diagram ERD is a visual representation of different data using conventions that describe how these data are related to each other. Terms that are simple and familiar always beats vague, technical-sounding words.
An entity should appear only once in a particular diagram.

The following example uses UML to show cardinality.
The capstone project aims to integrate knowledge and skills learned in the course, implement and enhance competencies emphasized in the fundamental subjects, apply and design skills acquired in the course, accomplish a comprehensive written report in the context of the capstone project for undergraduate studies and future IT professionals. The capstone project includes project proposal, feasibility studies, intellectual property teamwork, budget, schedule, management, professional communications, planning, design, implementation, deployment and testing.
Basic ER Diagram template Click to use as template. If an attribute can have more than one value it is called an multivalued attribute.
In naming entities, remember to use singular nouns. In particular, ER diagrams are frequently used during the design stage of a development process in order to identify different system elements and their relationships with each other.
