cannot differentiate between 32-bit and 64-bit servers in network applications. SecurityWINSERV03 will be the first major operating system to be released by Microsoft's "Trustworthy Computing" code review in early 2002. WINSERV03 includes a VPN security administrator, a new ieee802.1x wireless security standard, and a TCP/IP architecture based DNS, DHCP, NAT, IPv6. WINSERV03 will disable IIS6.0 and more than 20 other services by default, and reduce the privileges of some services such as Networ

PHP Object-oriented design principle--single responsibility principle I. Background principle of single duty (responsibility principle)There are many classes in a project, if the class does not distinguish between responsibilities, then it will appear to be very messy, the same maintenance also time-consuming; a single responsibility for a class consists of two meanings: avoiding the same responsibilities dispersed into different classes, and different responsibilities in the same class; Ii.

Recently, a new feature named AppLocker in Windows 7 is popular among anti-virus enthusiasts. If you are a security expert, you will know what the program is allowed to do. It is very dangerous. You will also know what functions the program should have and what functions it should not have. What you want to get is a set, never-disturbing solution. Applocker is quite practical for security experts. Figure 2 Applocker settings window Don't know what AppLocker i

When using the object-oriented idea for system design, our predecessors summarized seven principles: 1. Single Responsibility Principle (SRP) The core idea of a single responsibility principle is that every object in the system should have only one independent responsibility, and all objects focus on the fulfillment of their own responsibilities. It is short for SRP and short for simple responsibility princ

Single Responsibility Principle (SRP)-single Responsibility Principle The core idea of a single responsibility principle is:One class only does one thing and completes it well. There is only one reason for its change.. The single responsibility principle can be seen as the extens

role to provide a wide range of interfaces, that is, custom services, personalized services. is simply to provide the behavior that the client needs, and the behavior that the client does not need is hidden.The client should be provided with as small a separate interface as possible, rather than providing a large total interface.This is also a limitation of communication between software entities. But it limits the width of the communication, which means the communication should be as narrow as

Ood design principles Overview: Robert tcecilmartin,Bertrandmeyer,Barbaraliskov11 object-oriented design principles are put forward, which are regarded as the good bible by Object-Oriented designers. They can see their original text below: Http://c2.com/cgi/wiki?

1. If a class has too many responsibilities, these responsibilities are coupled. Changes in one role may weaken or suppress this class's ability to fulfill other responsibilities. This coupling will put the fragile (fragile) design upside down, and when changes occur, the design will suffer unexpected damages. P88 2. In SRP, we define the responsibility as a reson for change ). P89 3. The changed axis is meaningful only when the change actually oc

When learning and using OO design, we should understand that the emergence of OO enables software engineers to describe software systems in a way closer to the real world. However, software, after all, is built on an abstract level. how close it is to the truth cannot replace the truth or be replaced by the truth. The five principles of OO design are not isolated from each other. There is a certain correlation between them. One can be the strengthening or foundation of another principle. Violati

Term S. o. l. i. d. from Robert C. the first letter of the names of the five design principles collected in Agile principles, patterns, and practices in C # by Martin (Uncle Bob. 1.

Single Responsibility Principle (SRP. Definition: There shoshould never be more than one reason for a class to change. There should be only one reason for the change. Sometimes, developers may have some problems when designing interfaces. For example, user attributes and user behaviors are declared in an interface. This causes the Business Objects and business logic to be put together. As a result, this interface has two responsibilities and the inte

1. What does the title mean? 1.1 What is unit test? Unit testing aims to ensure the quality of code;1.2 What is decoupling? Decoupling aims to facilitate unit testing. Of course, another purpose is to keep the programScalability. Idea tools: To achieve decoupling of unit test and code (or oo code with good design) at the same time, the idea of dependency injection is an essential tool. The reason is thought. From the design point of view, this really requires ideological transcendence; It is

fields of the model and also adds some extra stuff, look at the color label and married check box.Here is a simple chart, the field on the left of the model, and the field to the right of the UI. The middle is a description of the logic of the mapping and transformation.You can see the first 2 fields we don't have any conversion logic, they only have the mapping logic. The other 2 field mappings and transformations have logic.The logic of transformations and mappings is usually in the backgroun
