What is Airline Reservation System?

An “airline reservation” is a legal contract in which an airline agrees to provide a passenger with a seat on a specific flight from one airport to another for a set fee. From the moment of the first reservation until flight completion, the contemporary airline reservation system is a comprehensive suite of products that support a variety of airline management activities and serve client needs.

How to create an Entity-Relationship (ER) Diagram

Time needed: 5 minutes.

Steps in building the ER diagram for the airline reservation 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:
    Field – 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.

  • Step 2: Finalize the entities included

    Start designing your ER Diagram by finalizing the entities that must be included in your airline reservation 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.

  • 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.

  • 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.

Conclusion

ER (entity-relationship) diagram is only one of the diagrams used to design and develop the Airline Reservation System. Each of the diagrams you design and create will help you in presenting your ideas and impart your abilities.

Creating the ER diagram will help you perceive the back end of the software which will hold all the data that’ll enter and exit the system. To learn more about the ER Diagrams and more, check out the related and recommended articles below.
