C / S structural software (ie, client / server mode) is divided into two layers of client and server, and the client is not an operation.
The input, output equipment, but also has certain data processing and data storage capabilities, by putting the application software
The calculation and data is reasonably allocated on both ends of the client and server, which can effectively reduce network traffic and server operations.
the amount. Due to the limit of the number of servers and data traffic, this structure is suitable for a bureau in the number of users.
Domain use. Most ERP (finance) software products in China belong to such structures.
B / S (Browser / Server Mode) is an improvement in the C / S structure with the rise of Internet technology. At this
Under the structure, the business logic of the software application is completely implemented in the application server side, and the user performs completely in the web server.
Now, the client only needs a browser to perform business processing, which is a new software system constructor. This structure
More choice for today's application software. Shuanghui software series products belong to such a structure.
1. Data security comparison. Due to the data distribution characteristics of the C / S structure software, the fire, stolen robbing
, Earthquakes, viruses, hackers, etc. have become terrible data killers. In addition, for group-level off-site software applications, C / S
Structure software must install multiple servers around and synchronize data between multiple servers. In this way,
Data security on each data point affects the data security of the entire application. Therefore, for the group-level large application
It is unacceptable to the security of C / S structure software. For the software of the B / S structure, due to its data set
Store on the headquarters database server, the client does not save any business data and database connection information, or no need to do
What data is synchronized, so these security issues will naturally do not exist.
2, data consistency comparison. In the solution of C / S structure software, large groups operating in different places are employed.
Install the area-level server all over place, and then perform the data synchronization mode. These servers must be synchronized every day.
Headquarters can get the final data. Due to local network failures, individual databases cannot be synchronized, even
Come up, each server is not a data on one time, and the data will never be consistent and cannot be used for decision. For B / S
Software Software, its data is centrally stored, and each business document that occurs directly into the central government.
Database, there is no problem with data consistency.
3, data real-time comparison. In group-level applications, the C / S structure cannot see the current business in any time, anytime, anywhere.
The situation, it is all afterwards; and the B / S structure is different, it can see all the current business happening in real time.
It is convenient for quick decision-making, effectively avoiding corporate losses.
4, data traceability comparison. Since the data of the B / S structure is centrally stored, the head office can be traced directly.
The original business documents of the branches (branches, stores) at all levels, that is, the result of the result is traceable. Most C / S
The software of the structure is different, in order to reduce the amount of data traffic, only upload the intermediate report data, it is impossible to find each at the headquarters
Original documents of branches (branches, stores).
5, service response timely comparison. The business process of the company, the business model is not a constant, and the company is not
Broken development will inevitably adjust. Software suppliers are not perfect, so they have deployed
Software products are maintained, and the upgrade is normal. C / S structure software, due to its application, it is necessary to
Using nodes for program installation, so even very small program defects require a long redeployment time, heavy
In order to ensure the consistency of each program, you must suspend all business updates (ie "shock update"),
Its service response time is basically invisible. The software of the B / S structure is different, and its applications are concentrated on headquarters servers, and each application node does not have any programs, and all application updates will be updated, and they can do a fast service response.
.
6. Comparison of network application limits. The C / S structure software is only available for private users or broadband users (more than 1 megaby)
And our B / S structural software can be applied to any network structure (including 28.8K dial-entered network), especially suitable for wide
Places that cannot be reached (for example, some of the Shuanghui Group, you can use the software system only on the Internet).
Comparison of C / S, B / S Software Business Application
Management software is serviced for corporate services. Enterprise selection management software is not only technically considered, but also from commercial use.
Aspect, the following will compare the software of the two structures from the perspective of commercial use.
1. Comparison of investment costs. The B / S structure software generally only has initial one-time investment costs. For groups, favorable
The software project is controlled and avoided IT black holes, while the software of the C / S structure is different, with the expansion of the application, the investment meeting
Continuous.
2. Comparison of hardware investment protection. Both structures are also completely different in terms of the protection of existing hardware investments.
When the application range is expanded, the general solution of the C / S structure software is the purchase of more advanced central services.
The actor, the original server is not used, which is due to the two-layer structure of the C / S software, the server program of such software
It must be deployed on a computer; and the B / S structure (such as Shuanghui Software) is different, and as the server load increases,
In order to smoothly increase the number of servers, then load balance between individual servers. Effectively protected the original hardware
investment.
3. Comparison of fast expansion supports for enterprises. For enterprises in growth, rapid expansion is its significant feature. example
For example, Shuanghui Commercial Company has a new distribution center every year, and there is a new store opening every month. Application software fast
Deployment is the necessary guarantee for the rapid expansion of enterprises. For software for the C / S structure, the server must be installed at the same time.
And clients, construction machine rooms, recruit professional management, etc., so it is impossible to adapt to the characteristics of rapid expansion of enterprises. B / S
Structure software, just install it once, just set up accounts, training.
Secondly, with the expansion of software applications, the demand for system maintenance talents may become the restriction of rapid expansion of enterprises.
bottleneck. If the company opens a hundred, the need for computer professional talents will be one of the huge challenges facing the company.
Thinking of human costs, there is no need to recruit so many professionals and keep them.
Therefore, using C / S structure software will inevitably restrict the future development of enterprises. In addition, most C / S structures have a communication
If the ODBC is directly connected to the database, the security is poor, and the number of users is limited. Users who connect to the database
Will keep an ODBC connection, which will always occupy the resources of the central server, and the requirements for the central server are very high.
The user expansion is greatly limited. The B / S structure software is different, and all users are connected by a JDBC.
When the buffer pool is connected to the database, the user does not keep the connection to the database, and the number of users is basically unlimited.
From the above analysis, it can be seen that the large management software of the B / S structure has an advantage that the C / S structural software cannot match.
From the perspective of foreign development trends, this also verified this. At present, foreign large enterprise management software is already B /
Structure of Structure, or you are experiencing transition from C / S to B / S structures. Actively investing B / S knot from many domestic software vendors
The trend of Software, the large management software of the B / S structure is bound to occupy the main management software in the future.
