What is Face Recognition Attendance System?
Facial recognition is software that thoroughly maps a person’s facial attributes and stores them in the database to be used as a reference whenever they need the recognition. To validate an individual’s identification, the software compares a live capture or digital image to a piece of saved facial information using deep learning techniques.
The entire atmosphere is automated with a facial recognition attendance system. You will not only collect attendance but also automatically record the student’s entry and exit times. It also provides efficient security of records for schools because it can properly identify the student who left the designated classroom and when.
What is ER Diagram?
The Face Recognition Attendance ER Diagram is referred to as the software database design. This ER Diagram is the graphical depiction of relationships between all the entities involved in the system. Its major components are Entities, Attributes, and Relationships.
The ER Diagram is used to build and troubleshoot the System’s relational database. It works best with DFD (Data Flow Diagram), which is responsible for data movement.
Importance of ER Diagram
The importance of ER diagram for face recognition attendance system is to help in modeling its data storage or database. It is the basis of the project’s database foundation for construction. This entity-relationship diagram (ERD) also aids in defining the data types to be stored such as their attributes and characteristics.
In addition to that, the ER Diagram also describes how an entity interacts with other entities. All other real-world projects are presented with ER Diagrams (database designs).

How to create ER Diagram for Face Recognition Attendance System with Cardinality Ratio
Time needed: 5 minutes
Steps in building the ER Diagram for Face Recognition Attendance System with Cardinality Ratio.
- Step 1: Familiarize the ER Diagram (Entity Relationship Diagram) Symbols and Cardinality
Entity Relationship Diagram – shows the structure of data types in a project. It uses symbols to clarify its parts and relationships. Their symbols and applications must be familiarized before you build the ER Diagram.
ER Diagram Symbols:
• Fields: Fields are the parts of a table that define the entity’s characteristics. In the database that the ERD models, attributes are commonly thought of as rows.
• Keys is a technique to categorize data qualities. It is used to organize ER diagrams and assist users in modeling their databases to ensure that they are efficient. This is also used to connect different tables in a database.
– Primary Key: identifies a single entity instance which means a unique attribute or set of attributes.
– Foreign Key: is produced when data attributes have one too many relationships with other entities.
ER Diagram Cardinalities:
The styling of a line and its termination demonstrates cardinality and ordinality.
The greatest number of times an instance of one thing can be related to instances of another entity is referred to as cardinality.
While Ordinality refers to the fewest number of times a single entity instance can be linked to another. - Step 2: Finalize the entities included
Start designing your ER Diagram by finalizing the entities that must be included in your blood bank management system. This entity is represented by a rectangle, and you’ll want to leave plenty of room for them in future phases so you may add them to your design.
An entity set is a group of similar entities with shared properties. A table or a table’s attribute is an entity in a database management system. As a result, by depicting relationships between tables and their characteristics, an ER diagram displays the whole logical structure of a database. - Step 3: Add the attributes of each entity
After finalizing the entities, think about the qualities you’ll need to characterize each entity. The details of the various entities outlined in a conceptual ER diagram are supplied as attributes. Characteristics of an entity, a many-to-many relationship, or a one-to-one relationship are all examples of attributes. Multivalued attributes can be assigned to several values.
The entity’s attributes were represented by ovals and can be seen in the tables of the blood bank management system er diagram. These attributes can be a primary key or a foreign key in the database design of the project. Yoy ER diagram design could also be converted to the database of the system by declaring your right entities and their attributes. - Step 4: Describe the relationships (cardinality) between entities and attributes
To plot relationships between the ERD you will need the entities, their attributes, and relationships. You will base the data structure from the evaluated information to have the exact Entity Relationship Diagram.
A relationship is an association that describes how two entities interact. At the connector’s endpoints, the cardinality is indicated by a crow’s foot. One-to-one, one-to-many, and many-to-many are the three most common cardinal relationships. It’s the maximum number of times an instance of one entity can be linked to instances of another entity.
Conclusion:
You need to know the diagrams used to design and develop the Face Recognition Attendance System. That is to help you create a fully-functional system with the use of ER Diagram. Creating it will help you perceive the back end of the software. This will hold all the data that’ll enter and exit the system.
