First, you need to expand the domain architecture before installing SCCM to ensure that there will be no problems during the installation process. This is the prerequisite for SCCM installation. The method to expand the domain architecture is very simple, but you need to manually perform the operation as follows:
NOTE: If there are multiple DC servers, you must start them. Otherwise, the domain

Everyone must look at the MVC source code,
I want to be able to string the MVC execution process in my head.
The main body design has been finished, source code collation, work relatively busy, forgive me,
As we were eager to drive out a prototype, we decided to move the mobile end to the back, so we only considered expansion without planning for the moment.
Although it has been extended, this must be taken into account when building the system architecture. Otherwise, subsequent modifications will cause you a headache.
, and consumers of services. Such a clear division helps isolate the problem and allows each component to be extended independently of other components. This type of service-oriented system design is very similar to the object-oriented design of program design.In our example, all the requests for uploading and retrieving images are processed on the same server. However, splitting these two functions into tw
development and production. In the face of this development trend, what we want is a brand new, open, and highly scalable architecture system, here I name it a plug-in Architecture (maybe different from the plug-in Architecture in other populations ).

In this paper, we illustrate the method of CI framework extending system core class. Share to everyone for your reference, specific as follows:
First of all, your system extension class is placed under the Application/core, the system core class is Ci_controller, so you can not start with ci_, you need to open application/config/config.php modify:
This article mainly introduced the CI Framework extension system core class method, combined with the example form to analyze the CI framework to implement the expansion system core class steps and related operation skills, the need for friends can refer to the following

Linux systems generally have 4 main parts:cores, shells, file systems, and Applications .

First, what is the C/S structure.
The C/S (Client/Server) structure is a well-known client and server structure. It is a software system architecture. It can take full advantage of the advantages of both ends of the hardware environment, and assign tasks to the client and server, thus reducing the communication overhead of the system. Currently, most Application
