-Title: XX software requirements analysis requirements: teaching management or self-referenced vision, with a simple descr iption of the scope of the software as small as possible methods: structured or object-oriented: 1. Structured approach: DFD: starting from the top, refinement to the software " features"　until the DD: only asked to describe the data structure processing instructions: Choose one only requires the method to choose 2. object-oriented approach: Choose a use case diagram use case diagram to describe a class diagram of class method does not require detailed against the use cases, write the sequence diagram
