principle of mandatory constraints, so that a module only solves the problem that a single module should solve, so as to avoid different problems together to solve the problem caused by beard eyebrows, but also avoid inappropriate dependencies and template references.Centralized configuration principle: in the tiny framework we have done a lot of work on the configuration, one is the COC method, if not, then the system default value; One is the centr

to blame yourself.
If you make a mistake, you don't have to say it to others, because people who know it don't have to say it to you. People who use it don't understand it.
It is a kind of beauty and crazy to achieve the ultimate in a simple task.It is a kind of courage and gas to solve a small detail problem.Sometimes, the paranoid character is not a defect, but an attitude, including people, and actions.In this world, girls cannot be caught, and they are not humiliated. What they face is that
development by many people. The system core developers with tens of millions of users on the portal website will not exceed 5-8. What's more, when many people develop, they should be responsible for one person as much as possible. On the contrary, many open-source frameworks have taken too much consideration of the multi-person collaborative development scenarios that do not conform to the actual situation in China, the framework is too loose and too streamlined. When two people develop project

Seasar is a popular JSP software development framework. Currently, seasar2 is an open-source framework very similar to Spring framework.The development model of seasar framework originated in Japan and is very popular in Japan.Seasar framework was first published in August, and was used as an application server relying on the Web Container jetty and database HSQLDB. Later, in March, it was transformed into a lightwei
adaptive projects. the framework and strategy only provide a general route to solve our first step. each project is different. any new problems should be adjusted and communicated in a timely manner.
Effect
Both consultants and customers have a good understanding of the project process and have more practical expectations.
Through the discussion of the framework and strategy, we will have a deeper understanding of the problem itself.
But avoid the tendency to hold a hammer in your hand to s

Advantage: (1) they have names.
(2) You do not have to create an object each time you call it.
(3) Any child type objects of the original return type can be returned.
(4) The Code becomes concise when you create a parameter instantiated object.
Deficiency: (1) category: If there is no public or protected object, it cannot be divided into categories.
(2) There is no difference with static methods.

Consultants can list the services they can provide, including various trainings, lectures, and workshop, so that the team can choose from them. no need to emphasize that the team must change after learning, so these services are like a kind of welfare, and the team can even participate without listening. in these training or lectures, the consultant should
