main program body code of the main package requires a long Compilation Time, or the SCP and notice packages are provided in the form of a shared library or DLL, the preceding modifications are necessary. Otherwise, if the program size is small and the compilation time required by the main code of the program can be ignored, the modifications are not required. After all, the modified program structure adds an abstract layer, which increases complexity. Design principles and patterns

Software Engineering--object-oriented analysis of theory, method and practiceDuring the requirements acquisition phase, developers focus on understanding the user and their usage needs. In the demand analysis phase, developers focus on understanding what the system needs to build, at the core of which is to produce an accurate, complete, consistent, and verifiable system model called an analytic model.The

This chapter mainly discusses object-oriented analysis, from the concept of analysis, identification and analysis of the class, the definition of interactive behavior, the establishment of analysis of the class diagram and evaluation of the mode of analysis of several aspects of the narrative. The object-oriented analysis model consists of three independent models, functional model, analysis

Ten principles of Object Oriented Software development (turn two) When you define the parameters of a method, be sure to make them extensible. For example, the following line of code is not extensible: Public Function PlaceOrder (slastname As String, Sfirstname as String, saddress as String) To invoke this method you must pass these 3 parameters. But if you later decide you need a phone number on an or

/projects/structuremap/files/Ninject:http://ninject.org/downloadUsing the existing broad application framework above, spring.net originates from Java's Spring, is more complete and powerful, AUTOFAC and Ninject are more clear and friendly, personal recommendation use autofac+ other framework combination.4, interface Isolation principleRequirements: Use a dedicated small interface as much as possible, rather than the total interface, to avoid complex interfaces.5, the Richter replacement principl

Architecture of object-oriented software requirements Here, we need a specific way of thinking and a unique methodology. It is necessary to correctly understand and properly use the classical demand analysis theory.1. establish a system's overall framework as soon as possible in terms of ideological methods, and generally locate the positions of various specific targets in the system framework and their rol

Review:Inheritance: Is the relationship between classes and classes, and what is a relationship of whatThe purpose of inheritance is to solve code reuse problems and reduce code redundancyInheritance is to inherit the attributes of the parent class to the subclass.Derivation is a subclass that derives its own new propertyclassteacher:def __init__ (self,name,age,sex,salary,level): Self.name=name Self.age=Age Self.sex=Sex self.salary=Salary Self.level=Level def walk (self): print ('%s is walking'%
