   The instructor begins by underlining the title 'Package Diagram' and the phrase 'class diagrams' in the first bullet point to highlight the relationship. He writes the word 'separate' and 'class' on the right side of the screen to emphasize the distinction. He then focuses on the diagram, writing 'Holding' over the 'Accounting' package and 'Hd' over the 'HR' package. In the center, he writes 'organization of packages' to explain the core function. He draws arrows and checks to illustrate the flow and dependencies between the Accounting, HR, and Invoice packages, specifically noting the dashed lines indicating dependencies. The diagram shows 'Accounting' containing 'Add accounts' and 'Remove accounts', while 'HR' contains 'Get employee details' and 'Adjust accounting'.

The lecture segment defines Package Diagrams as a specialized view within class diagrams used for organizing system components. The instructor uses a visual example with Accounting, HR, and Invoice packages to demonstrate how dependencies are managed. By annotating the slide with terms like 'organization of packages,' he reinforces the concept that these diagrams group related elements to reduce coupling. The handwritten notes clarify the specific interactions and structural organization intended by the diagram, showing how different modules like Accounting and HR interact through defined dependencies.
