start this talk by introducing the taxonomy of design patterns at a high level, how to read a UML diagram (as a quick refresher), a refresher on inheritance vs composition, and then spend the rest of the learning more design patterns 87Unified Modeling Language (UML) A compact way to represent software systems 88What is the Unified Modeling Language (UML)? 89 ● A general-purpose modeling language for software architect for larger systems ○ i.e. Drawing a diagram and planning before diving into code is wise!Sample UML for a Class Diagram (1/4) ● Example of a class diagram ○ Class name ○ member variables (data)

UML diagramsSome real funny diagramsWidely used proprietary tools Visio Enterprise Architect No longer com/jgraph/drawio-desktopText to diagram converters • PlantUML • open source tool that converts simple textual descriptions to UML diagrams • Not only UML diagrams - Earth diagram, UI wireframes and more Integration to doxygen doc / markdown doc http://plantuml.com/guideThree simple lines generate this diagram…. Isn’t it awesome?Have a break! • Use PlantUML to create Sudoku. • The sudoku is randomly

programmatically the meaning of descriptive text of a particular software artifact, or even an UML Diagram. Therefore, it can serve as an signature of an software artifact. • The resulting binaries are

structures, including: • Base Types, Custom Types, Different Containers, Nested Types. • The diagram shows how these base types and containers can be combined to form complex data structures. Fanchen sent directly. • Deserialization without decoding: Data is accessed and modified directly. • The diagram shows that our method removes the need for encoding and decoding steps, simplifying the serialization include: • Serialization & deserialization • Read & write • In-place/non-in-place write • The diagram illustrates that, just like a road without bottlenecks allows for smooth traffic flow, we need
