I. Classification of requirements
Requirement analysis is an important process of building software system. Generally, the requirement type is divided into three types:
1, business requirements (business requirement) reflect the organization or customer requirements for the system, product high-level, they are described in the Project view and scope documentation.
2. The user requirements (username requirement) document describes the tasks that users must complete to use the product, as descr

This article mainly introduces the information about how AngularJS can asynchronously load instance code as needed. For more information about how AngularJS supports multi-view applications through routing, You can dynamically load the desired view based on routing, the AngularJS documentation provides a detailed introduction. There are also many tutorials on the Internet, so you don't need to introduce them!
As the number of views increases, the number of js files increases. AngularJS loads al

Starting with this joke story, many people may think that this kid is the best candidate for demand research. Looking back at many cases in software development, the failure rate of software development remains high,This value may be higher, especially in outsourcing development. When analyzing the cause of project failure, the requirement may be the key cause of failure, the requirement is unclear, and the custom
Over the past decade, the domestic software engineering progress has been obvious to all.
