什么是SDLC？

SDLC stands forSoftware Development Life Cycle。When building software, there are certain phases that should be followed. Every software development organization follows SDLC for the software project. There are various phases in SDLC. A basic understanding of the problem is identified in the planning stage. Discovering the risks associated with the project, technical difficulties, resources, development efforts are also identified in this phase.

In requirement phase, the first activity is to gather and analysis requirements. Gaining customer inputs, meeting the senior managers and get details about sales, and marketing happens in requirement gathering. The gathered requirements should be documented properly. This document is known as theSoftware Requirement Specification (SRS)。它包含在项目生命周期期间设计和开发的产品要求。

The software design is derived from the SRS. More than one design approach for the product architecture is proposed and documented in aDesign Document Specification (DDS)。在此阶段，设计了所有架构模块，具有外部模块等的数据流表示。

在实施中，该项目是使用合适的编程语言实施的。各种编程工具，例如compilers, interpreters, code editors,IDEs, anddebuggerscan be used to write and test the programs. The programming language can be chosen according to the application. The unit testing for the developed module is done in this phase.

Testing is the process of verifying and validating that a software program works as expected. It is used to find out whether the final project has come to the expected requirements. Testing involves the integration testing, system testing etc. Integration testing is to perform testing between two modules. The system testing is the complete project testing.

Finally, the product is released to the market. Depending on the customer feedback, new features can be added to the product. The maintenance and required services are provided to the existing customers. Those are the major phases of SDLC.

What is Agile Methodology?

During the software development process, a software development life cycle model should be followed. These models are known asSoftware Development Process Model。Each process follows a certain number of steps unique to its type to successfully complete the software project. Some examples of SDLC models are waterfall model, iterative model, spiral model, v model, prototype model, Rapid Application Development, etc.

敏捷方法也是SDLC模型。它是迭代和增量过程模型的组合。该模型有助于适应需求的更改。在此模型中，该项目分为几个模块。假设该项目分为三个模块，为A，B和C。First模块A会通过计划，需求收集和分析，设计，实施和测试。完成后，B模块开始。它也经过同一阶段，例如模块A。当B完成时，模块C启动。在迭代结束时，可以向客户提供一个工作模块。

There are many advantages of Agile. In the traditional瀑布模型，一旦定义了要求，就无法更改它们。但是在敏捷中，可以更改要求。开发人员与客户之间也有更多的合作。它改善了团队合作，并使项目易于管理。总体而言，敏捷是一种流行的SDLC模型，因为其灵活性和适应性。它可能不适合复杂的项目。其他缺点是，客户可以始终更改要求，并且有必要让敏捷的领导者指导该项目。

What is the Relationship Between SDLC and Agile Methodology?

• Agile methodology is a SDLC model.

SDLC和敏捷方法有什么区别？

SDLC vs敏捷Methodology
SDLC is the process of dividing software development work into distinct phases to improve the design, product management, and project management.	敏捷方法论一种软件开发方法，其中需求和解决方案通过自我组织和跨功能团队及其最终用户的协作努力而发展。
Usage
SDLC用于组织管理软件开发工作。	敏捷用于提高灵活性并适应项目的需求更改。

概括–SDLC vs敏捷Methodology

This article discussed the difference between SDLC and Agile. The difference between SDLC and Agile Methodology is that SDLC is the process of dividing software development work into distinct phase to design and develop a high-quality software while Agile Methodology is a SDLC model.
