Study Notes

Package Diagram

A package diagram describes the structural organization of software systems, showing dependencies between packages or modules.
It provides an overview of the entire system, helping developers understand the system's architecture and dependencies.
Relationships shown in a package diagram include containment, dependency, and inheritance.

Creating Hierarchies with Package Diagrams

A package diagram can create hierarchies in software systems by showing relationships between packages or modules.
Packages can be nested inside other packages, creating a hierarchical structure that reflects the organization of the system.
This helps improve clarity and organization, making it easier to manage and maintain the system.

Examples of Package Diagrams

Online Shopping Website

Packages: Web Shopping, Mobile Shopping, Phone Shopping, Mail Shopping, Merge > Payment Shopping Cart
Merge > Payment Shopping Cart depends on Web Shopping, Mobile Shopping, Phone Shopping, and Mail Shopping packages to access and merge shopping carts.
Customer and Inventory packages may have dependencies (import relationships) with other packages.

Hotel Management System

Packages: Hotel Management System, Front Desk Module, Reservation Module, Billing Module
Front Desk Module depends on Reservation Module to check room availability and manage room assignments.
Front Desk Module may also depend on Billing Module to handle billing-related tasks.
Reservation Module depends on Front Desk Module to provide information about room availability and handle room assignments.

University/Multinational Organization Department

Packages: University/Multinational Organization Department, Human Resource Module, Finance Module, Operations Module, Core Functions
Human Resource Module depends on Finance Module to access budget information and manage payroll activities.
Finance Module depends on Human Resource Module to gather information about staffing levels and employee salaries for budgeting and financial planning.
Operations Module depends on Human Resource Module to gather information about staffing needs and employee availability for scheduling operational tasks.
