Additional OODB Case Studies

Object-Oriented Databases (OODBs) provide a way to store data in a format that is consistent with object-oriented programming principles. This lesson explores several case studies that demonstrate the practical applications of OODBs in various domains.

Overview

An e-commerce platform requires a robust database system to handle complex product information, customer data, and transactions.

Implementation

class Product {
    String id;
    String name;
    double price;
    String description;
}

class Customer {
    String id;
    String name;
    List cart;
}

class Order {
    String id;
    Customer customer;
    List products;
    double totalPrice;
}

In this case, using an OODB allows for seamless relationships between classes and supports complex queries.

Overview

A healthcare management system manages patient records, appointments, and billing information.

Implementation

class Patient {
    String id;
    String name;
    List appointments;
}

class Appointment {
    String id;
    Date date;
    String doctorId;
    Patient patient;
}

class Billing {
    String id;
    Patient patient;
    double amount;
    boolean paid;
}

Here, the OODB's ability to handle complex data structures helps maintain relationships between patients and their appointments.

Overview

An educational institution uses an OODB to manage student records, courses, and faculty information.

Implementation

class Student {
    String id;
    String name;
    List enrolledCourses;
}

class Course {
    String id;
    String title;
    List enrolledStudents;
}

class Faculty {
    String id;
    String name;
    List coursesTaught;
}

This case study illustrates how OODBs simplify the management of interconnected data entities.

• Design your object schema according to real-world entities.
• Utilize inheritance to minimize redundancy.
• Implement relationships wisely to avoid complex queries.
• Consider performance implications when designing your data model.
