Article Description: discussion on IPhone Web App navigation design. I'm currently working on the iphone web App. Because the product form is novel, the technical environment is immature, the company gives the more relaxed research and development time. In the one-month interactive design phase, each link has been discussed several times, I learned a lot from it. The

Recently, some students asked me how to better build the entire system by obtaining a software requirement, based on my experience, I will briefly introduce how I designed a software system. Of course, this is just a simple idea of mine. It may be much more complicated when it comes to a large software project. To design an object-oriented

Introduction For the embedded software component platform, its support platform is first an embedded real-time multi-task operating system, and secondly provides development tools and an integrated environment for the design of the entire software component. In the design process of the supporting platform, the whole embedded real-time multi-task operating
