solid design principles c#

refactoring techniques can find its existence, it is the simplest but most difficult to apply the principle of the need for designers to discover the different responsibilities of the class and separate it, The multiple responsibilities of the discovery class require designers to have strong analytical and design skills and related refactoring experience.example of a single responsibility principleExample descriptionA Java-based

satisfied first; Note: Often we do not adhere to the third paradigm in the design table, because the reasonable sink residual field will give us to reduce the join query; For example: The album table will be added to the image of the click Number field, in the album Picture table will also add the image of the click Number field; MySQL Database design

PHP design patterns-six principles. PHP design patterns-six principles code that follows the six principles is generally considered to be scalable and reusable: These six principles should be followed by any object-oriented langua

service invocation and assembly, while SDO defines and regulates the data in the service world, which has a clearly defined information model, independent of the data source and the specific data access technology, Makes it easier and more efficient for services to access data and exchange data between services.Many companies have supported SCA/SDO on the Java EE platform and have also provided C + + versions. IBM WebSphere Process Server 6 implement

depend upon details, details should depend upon abstractions.Another expression is:to program for the interface, do not program for implementation. The English definition is:Program to a interface, not an implementation.analysis of dependency reversal principleThe dependency reversal principle was Robert C. Martin's third engineering notebook in 1996 for the C + + Reporter column, which he later joined in

class must be self-compatible with its base class.◆ Dip: The dependency inversion principle depends on abstraction rather than implementation.◆ ISP, interface isolation principle, customers only need to pay attention to the interfaces they need. The other six items are about the package design principles. In this article, a package refers to a binary publishable file, such as A. jar file or DLL file, rat

creates a problem: The table is the Union primary key with the order number and the product number. In this table, the product name, unit, commodity price and other information is not related to the table's primary key, but only related to the product number. So this violates the design principle of the second paradigm. And if the Order Information table is split, the product information is separated into another table, the Order Item table is also s

directly with each other, then these two classes should not have direct interaction, and if one of the classes needs to invoke a method of another class, the call can be forwarded through a third party. The fundamental idea of this principle is to emphasize the loose coupling between classes, and the weaker the coupling between classes, the more beneficial the reuse, the more weakly coupled class is modified and does not affect the related classes. In the structure

This article explains the principles that programming should follow. I just want to give a rough translation, or take a closer look at the English language so that it will not be misled by others. The principles of good programming By Christopher Diggins Today's post is a lightly edited repost from my blog at the area, a web-site dedicated to users of AutodeskMedia and entertainment products.
