1. Software Requirements Modeling: Guiding Principles
Guiding principles for software modeling help ensure software engineering is a thoughtful process. In this lesson, you'll learn more about the eight important principles that guide the process of software development.
2. What is Software Prototyping? - Definition, Models & Tools
This lesson introduce you to the world of software prototyping, including its advantages and disadvantages. You will learn the four-step process and two basic models used in software prototyping before testing your knowledge with a quiz.
3. Requirements Engineering: Overview & Elements
In this lesson, we'll define Requirements Engineering, collaboration, use cases, the elements of the requirements model, and negotiation and validation. At the end, you should have a good understanding of this important engineering concept.
4. Scenario-Based Requirements Modeling: Definition & Application
Scenario-based modeling is defined and explained within the greater context of requirements modeling for software engineering. Use case and activity diagrams are also explained using examples.
5. UML Models: Design & Examples
The Unified Modeling Language (UML) is widely used in software engineering, in the requirements modeling phase. The following lesson will help you learn about UML models and their design. We will also explore some examples along the way.
6. Data Modeling in Software Engineering: Objects, Attributes & Relationships
This lesson will explain data modeling within the context of requirements modeling for software engineering. Data objects, attributes, and relationships will also be explained through a use case example.
7. Class-Based Data Modeling: Definition & Application
Class-based modeling is reviewed in the context of requirements modeling for software engineering. Components such as identifying analysis classes, specifying attributes, and defining operations are discussed through an example use case.
8. Practical Application for Software Engineering: UML Case Diagram
UML case diagrams are perfect for documenting the way in which various user types will interact with an application. It integrates and maps workflow processes to IT systems.
