课程1
面向对象设计
4.7
507 个评分
This course takes Java beginners to the next level by covering object-oriented analysis and design. You will discover how to create modular, flexible, and reusable software, by applying object-oriented design principles and guidelines. And, you will be able to communicate these designs in a visual notation known as Unified Modelling Language (UML).
You will be challenged in the Capstone Project to apply your knowledge of object-oriented design by evolving and documenting the Java codebase for an Android application with corresponding UML documentation.
After completing this course, you will be able to:
• Apply the Class Responsibility Collaborator (CRC) technique to analyze and design the object-oriented model for a problem.
• Explain and apply object-oriented modeling principles and their purpose (e.g., abstraction, encapsulation, decomposition, generalization).
• Explain and apply different types of inheritance
• Explain the difference between association, aggregation, and composition dependencies.
• Express object-oriented models as Unified Modeling Language (UML) class diagrams.
• Translate between UML class diagrams and equivalent Java code.
• Apply design guidelines for modularity, separation of concerns, information hiding, and conceptual integrity to create a flexible, reusable, maintainable design.
• Explain the tradeoff between cohesion and coupling.

Design Patterns
4.6
311 个评分
This course extends object-oriented analysis and design by incorporating design patterns to create interactive applications. Through a survey of established design patterns, you will gain a foundation for more complex software applications. Finally, you will identify problematic software designs by referencing a catalog of code smells.
You will be challenged in the Capstone Project to redesign an existing Java-based Android application to implement a combination of design patterns. You will also critique a given Java codebase for code smells.
After completing this course, you will be able to:
• Demonstrate how to use design patterns to address user interface design issues.
• Identify the most suitable design pattern to address a given application design problem.
• Apply design principles (e.g., open-closed, dependency inversion, least knowledge).
• Critique code by identifying and refactoring anti-patterns.
• Apply the model-view-controller architectural pattern.

软件架构
4.4
154 个评分
The way that software components — subroutines, classes, functions, etc. — are arranged, and the interactions between them, is called architecture. In this course you will study the ways these architectures are represented, both in UML and other visual tools. We will introduce the most common architectures, their qualities, and tradeoffs. We will talk about how architectures are evaluated, what makes a good architecture, and an architecture can be improved. We'll also talk about how the architecture touches on the process of software development.
In the Capstone Project you will document a Java-based Android application with UML diagrams and analyze evaluate the application’s architecture using the Architecture Tradeoff Analysis Method (ATAM).
After completing this course, you will be able to:
• Compare and contrast the components, connections, protocols, topologies, constraints, tradeoffs, and variations of different types of architectural styles used in the design of applications and systems (e.g., main program and subroutine, object-oriented, interpreters, pipes and filters, database centric, event-based).
• Describe the properties of layered and n-tier architectures.
• Create UML ipackage, component, and deployment diagrams to express the architectural structure of a system.
• Explain the behaviour of a system using UML activity diagrams.
• Document a multi-application system with a layered architecture.

面向服务的体系结构
4.4
127 个评分
Based on an understanding of architectural styles, you will review architectures for web applications, then explore the basics of Service-Oriented Architecture (SOA) in two approaches: Web Services (WS*) and Representational State Transfer (REST) architecture.
In the Capstone Project you will connect a Java-based Android application with Elasticsearch, a web service with a REST application programmer interface (API).
After completing this course, you will be able to:
• Describe SOA (Service-Oriented Architecture) to structure web-based systems.
• Explain WS* services (i.e., SOAP over HTTP, WSDL, UDDI, BPEL).
• Apply REST architecture (i.e., JSON over HTTP, URI).
• Identify REST design principles.
• Create a system using REST interfaces.
• Apply microservice architecture.

退款政策是如何规定的？
我可以只注册一门课程吗？
可以！点击您感兴趣的课程卡开始注册即可。注册并完成课程后，您可以获得可共享的证书，或者您也可以旁听该课程免费查看课程资料。如果您订阅的课程是某专项课程的一部分，系统会自动为您订阅完整的专项课程。访问您的学生面板，跟踪您的进度。
有助学金吗？
我可以免费学习课程吗？
此课程是 100% 在线学习吗？是否需要现场参加课程？
此课程完全在线学习，无需到教室现场上课。您可以通过网络或移动设备随时随地访问课程视频、阅读材料和作业。
完成专项课程需要多长时间？
Each of the four courses in the Specialization are designed to be completed in 4 weeks; the entire Specialization can be completed in 16 weeks. On average there is one assignment per week for the first 8 weeks (occasionally a week without an assignment will be followed by a week with two assignments). The last 8 weeks average fewer than one assignment per week.
Depending on capacity to complete assignments, we expect learners to finish any of the courses in 3 – 5 weeks.
What background knowledge is necessary?
Familiarity with object-oriented programming structures is essential. Basic Java programming knowledge is expected. Assignments and quizzes will require coding in Java. The capstone application will require you to use Android Studio, an integrated development environment.
Do I need to take the courses in a specific order?
If you are intending to complete the entire specialization, it is highly recommended to take the courses in order as material presented in early courses will be referred to in later courses. If you are interested in specific courses, each course can be taken as a standalone course, provided that you are familiar with the content of previous courses.
完成专项课程后我会获得大学学分吗？
Software Design Architecture courses are not eligible for university credit.
What will I be able to do upon completing the Specialization?
You will be able to create better software applications and systems that are reusable, flexible, and maintainable, because your software will follow established design principles, patterns, and architectures. You will also be able to communicate to others your software designs and architectures through industry standard visual notations.
