16th Chapter My first impression is that in the IT industry, innovative thinking is very important. Now the social development is so rapid, it is difficult to innovate, some people have innovative ideas, but there is no corresponding technology, some people have superb technology, but there is no innovative understanding of the technology. When we are sometimes at the moment, we have to grasp the record and practice with our own hands, so that there is a possibility of success, and innovation is sometimes very simple, perhaps not the need for excellent professional knowledge, it is not necessarily the field of their own good, sometimes just a simple idea in the brain may be the key to success. Innovation sometimes depends on not your efforts, and your team to communicate with each other to make up, so that it is possible to make innovative ideas more plump, and success is closer, and your team does not need to be top experts, as long as we work together can also come up with a very successful innovative ideas.
Eighth Chapter

I understand that

1. Determine the overall needs of the system: functional requirements, performance requirements, reliability and availability requirements, error handling requirements

, interface requirements, constraint requirements, reverse requirements, possible future requirements (extensibility), and so on.

2. Analysis of the system data requirements: Since our software system is generally a series of data or information processing, so in the process of software development, the system is involved in the process of data analysis is also very important. Usually we analyze the data by modeling it, that is, the e-r graph.

3. Export the logical model of the system: in the requirement analysis, we can derive the logical model of the system through a series of models, so as to make it easier for us to have a more intuitive understanding of the system. The models commonly involved are: functional models, data models, behavioral models, algorithmic logic models, and so on.

4. Revision of the System development plan: At the end of the feasibility analysis phase we developed a development plan that, after conducting the requirements analysis, we can revise the unreasonable parts of the development plan according to the results of our analysis.

The main task of demand analysis. Demand analysis has 4 major tasks:

1. Determine the overall needs of the system: functional requirements, performance requirements, reliability and availability requirements, error handling requirements
