Chapter 1152 The Assistance of Artifact
It was not a good day to talk, so Zhou Zhi changed the topic and asked little Lei Ge about the origin of this car.
In the end, this matter was mainly due to Guan Ma.
Guan Dabin was formerly the deputy general manager of Heheng. He established a large supermarket in Shudu. In addition to airborne top leaders, financial management, and information system managers, he also provided local supply organization, human resources management, and logistics and warehousing coordination. , in fact, it depends on him.
Heheng Group and Jinli Group began to operate chain supermarkets at Zhou Zhi's suggestion, so after training, Guan Dabin was picked up again and given important tasks.
Li Lehai and Jiang Wu took a word each from Heheng Supermarket and Red Star Chain and established a joint subsidiary called "Hengxing Supermarket United Group". They also exchanged equity and packaged Heheng Supermarket and Red Star Chain into a joint venture. A large supermarket complex.
This architecture itself is also very consistent with the star system. Large supermarkets like Heheng Supermarket are stars, and the medium-sized small supermarkets of Red Star Group are planets and satellites.
However, under the control of the supermarket information system, this galaxy can operate smoothly and orderly. The productivity and competitiveness improvements brought by information technology to the industry are extremely obvious, so this knowledge was purchased by Clover Company. The supermarket management system that has been revamped and upgraded has also been shamelessly renamed by Zhou Zhi - a well-known local name - "Star Supermarket Management System Version 1.0".
The word "super business" has also changed its nature here, becoming the abbreviation of "super business", and has also become a stellar system. The entire super business includes finance, customers, business, warehousing, logistics, and human resources. There are multiple system sub-modules such as intelligence analysis, statistics, and auditing. Each sub-module can operate independently, and has a unified interface to share information with other modules, building an "information flow network" that can fully support the operation of modern enterprises.
Because the system is not connected to the Internet yet, it is quite awkward to operate. The information processing of the system has to be carried out by employees of the information technology department to carry computers to various supermarkets to copy the data, and then centralized batch processing, and then by They carry computers and go to various supermarkets to distribute updated data.
However, Zhou Zhi insisted that the system be designed in this way. At the same time, in terms of architectural model, he abandoned the pure CS model that is quite popular today, and resolutely adopted the BS and CS mixed model to build the system, and required the system to be as de-CS as possible.
The so-called BS and CS architecture are actually two common software architecture design patterns.
BS architecture, Browser/ServerArchitecture, is based on communication between the browser and the server. The logic and data of the application are stored on the server, while the client only uses the browser to request data and interact through the network. operate.
The CS architecture, that is, Client/Server Architecture, is based on communication between the client and the server, storing the logic and data of the application on the server, while the client uses the terminal device to run part of the program Code to process data and interact with each other.
In fact, both architectures have their own pros and cons. Which one is better or worse mainly depends on the application environment.
The benefits of BS mode are self-evident. All programs and data are concentrated on the S side, which can achieve unified maintenance and unified management. The data synchronization is single and superior. The client does not need to upgrade or purchase special equipment. It only needs a computer with The browser's computer can handle the transaction.
The disadvantage is that the speed of the network and server is high. A large amount of data needs to be obtained from the server in real time through the browser and real-time feedback is required. The amount of information exchange data is huge, which often causes network and system failures. Blockage, or even total system paralysis.
The benefit of the CS mode is the other way around, because part of the business is processed locally, and only information that needs to be communicated with each other will be uploaded to the S-side, or downloaded from the S-side, and it can also undertake a considerable part of the local operations. work, with much smaller requirements on the network and central server.
The problem is that each C-side needs to install a set of C-side service programs, and the computer performance required by each C-side is much higher than the terminal performance in BS mode. The biggest problem is not the cost, but the unity with the system, the uniqueness of the data, and the complexity of management.
Once the system needs to be upgraded, all C-sides must be upgraded simultaneously, which is a huge workload.
In addition, data, programs, and servers are all distributed, which can easily lead to inconsistent versions of the C-side and S-side systems, differences in data between the two places, etc. The system is small and the data is simple, which is easy to handle. If the system If the amount of data and data is very large, it will easily cause huge troubles to the information management work, and even cause the system and data to be non-backupable and unrecoverable due to program version differences and data differences at time nodes, which is quite serious. fatal.
To give a simple example, in BS mode, data backup is very simple, because the data is only on the S side. You only need to select a time period and back up the current data to complete the risk prevention work.
But when switching to CS mode, data backup is troublesome. A backup mechanism needs to be equipped for both the S side and the C side, and the backup time point must be set uniformly, so that the backed up system can be used by the entire system. The system is restored to that point in time.
However, the system backup equipment also needs to consider the cost, so it is usually only performed on the S side. Due to the inherent limitations of the CS system, when the S side is backing up, the C side continues to operate, so this part of the new Data will never be able to enter the backup data on the S side.
There will always be data differences between the S end and each C end, and these differences can never be backed up.
When doing data recovery, you will find that no matter which point in time the backup is restored, some data on each C-side will be missing, and the system will no longer be able to restore all C-sides and S-sides. The end is completely consistent with a historical state at a point in time, which results in partial non-traceability of the system.
In many scenes, such non-traceability is not serious. However, for some scenes, non-traceability can easily cause management traps, giving people an excellent opportunity to commit crimes freely and completely destroy the evidence of the crime.
For finance and financial work, data cannot be trusted or traced, which will be fatal.
However, in today's system design work, due to network limitations, the development of BS mode has been completely restricted. Therefore, everyone mainly adopts CS mode to design systems, and because today's systems are relatively "small", So CS mode is very easy to use.
However, the trap is hidden in the word "smooth". When development continues, countless technology companies will find that they must tear down their entire systems and rebuild them. By that time, they will even find that the system has become so large that once it is rebuilt, The design cost will be too high for enterprises to bear.
If a ship is in danger of turning around, it is better to allow its design to develop and be sustainable from the time it is a small boat. This is a profound lesson Zhou Zhi learned from the fate of the Chinese character library in another life.
In short, with the help of this set of "artifacts", enterprise management has become relatively easy, so the enterprise's focus has shifted even more to Guan Dabin, and promotion and reuse are all part of the problem.
Now that there is a talkative husband in Shudu Supermarket, the opportunity to Guan Ma has come.
