- Share examples of a system context diagram
- Provide the definition of the behavioral model for software requirements
- Showcase an understanding of patterns used for requirements modeling in software engineering
- List challenges of gathering requirements for web applications
- Create a UML sequence diagram
1. What is a Data Flow Diagram?
In this lesson, you'll learn what a data flow diagram is, how it is different from a flow chart, and some common uses for data flow diagrams. You'll also find out how to create your own simple data flow diagram.
2. Control Flow Diagram in Software Engineering: Symbols & Example
When designing software, we need to understand how the control of the program flows. This lesson will explain the control flow diagram. We will discuss the symbols involved and provide an example.
3. Use Case Diagram, Document & Templates Overview
Use cases are commonly used in software and system design, and they come in many forms. Learn about the different tools used for documenting use cases, including UML diagrams, written documents, and templates to aid in using a consistent use case format.
4. System Context Diagram: Description & Examples
In this lesson, you will learn the three key elements of a system context diagram. In addition, this lesson will describe how you can use this powerful diagramming tool to help identify the scope of a system.
5. Behavioral Model for Software Requirements: Definition & Example
In this lesson, we'll take a look at the behavioral model in requirements gathering by defining it, evaluating use cases, identifying events, explaining state representations, and seeing an example of a state diagram. In the end, you should come away with a solid understanding of these concepts.
6. Requirements Modeling in Software Engineering: Classes, Functions & Behaviors
This lesson will explain the concepts of requirements modeling in the context of software engineering. Topics covered include the patterns used, as well as classes, functions and behaviors. We will also briefly touch upon an example state diagram using UML (Unified Modeling Language).
7. Requirements in Web Applications: Examples & Challenges
In the lesson you will learn about the importance of requirements gathering in building a web application. The lesson will also introduce some of the challenges faced during this process.
8. Practical Application for Software Engineering: UML Sequence Diagram
UML sequence diagrams, also called event diagrams, are useful to software developers who are experimenting with software behavior. They are especially helpful at predicting behavior in any given run-time scenario.
