And discuss the key issues. In general, Datong thermal customers have a strong sense of responsibility and enthusiasm. All of us adhere to the idea of exposing problems and solving problems as soon as possible, actively promote the project progress, and prevent problems from being hidden until the project goes online. I also got a lot of user stories from customers, which are very valuable. On April 10, the second week of project implementation, the colleagues in charge of data migration began to be stationed. Datong Thermal's customer base data is about 600000, and the historical data of 7 years constitute a large amount of data since I started the project, so we attach great importance to data. One step of data migration is data analysis.

There has never been such a big fight on other projects, because the magnitude of data cannot be reached. This time, we have organized a special team to be responsible for the performance test and optimization of Datong Thermal. The test is divided into performance troubleshooting stage and stress test stage. Performance troubleshooting stage: test all the functions of the system according to the test cases, find out the functions that lead to the increase of system resources and slow response, record them, and optimize the performance problems exposed in this stage. Stress test phase: perform concurrent stress test on common functions. In this phase, we focus on several main performance indicators: response time, throughput, and system resource consumption. First, the common functions that need stress testing are determined and the test scripts are sorted out. Determine the test concurrency of 5,10,15,30,50 according to the actual use of the customer, and simulate 5010015030500 people using the system at the same time. Lock the functions with performance problems according to the concurrency test results, and determine how to allocate the resources of each virtual machine and how many Tomcat clusters to create. On site training At the beginning of August, Director Xu called me to the office to discuss the system training.

The implementation must be carried out in accordance with the customer needs and contract agreements in the early stage. The charging software has set a boundary for the implementation work, which helps our engineers and customers reach an agreement faster and build trust. Training arrangement: a large-scale centralized training for 1-2 days, providing documents, videos and examinations; Follow up targeted training and coaching. Data migration: the primary data migration is completed by the toll collector under the guidance of Excel provided by the toll collection software; Advanced data migration is led by charging software, and finally verified by heating enterprises; WeChat public account operation: Toll Ease software is responsible for business docking, such as query, payment, repair and suspension; The heating enterprise arranges special personnel to be responsible for the backstage operation, mainly including customer messages and news release. Data confidentiality: Toll Ease Software guarantees not to disclose Party A's data to three party organizations or individuals without Party A's authorization. Fault recovery: If the system cannot be used due to virus or other reasons, the system recovery shall be carried out, and the recovery data shall be subject to the new data available. Repair services do not include network environment processing, server operating system reinstallation, computer maintenance and other operations unrelated to business systems. The practice background of the group version of the heating charge management system is that "long hours must be combined, long hours must be separated", which is also very applicable in the heating industry. In the period of large-scale urbanization, it involves projects, funds, management, talents, etc.

Cooperate with important domestic group heating enterprises to form a national version of a non local group popular with large heating groups. In the future, heating enterprises will also become more pragmatic, more determined and cautious on the road of information construction, and they will spend more time to choose partners, products and services. I think this is just in line with the development concept of fee based software. Customers are not so rapidly expanding. They have time to choose software slowly. We have patience to build software slowly, which is win-win. Datong heat charging customer service informatization construction record of 6.45 million yuan should be a big target of domestic heat enterprise charging and customer service informatization software and hardware, and also a big project of charging software so far.

Jiangsu wisdom Natural gas charging system software Service, production and other system data are integrated for big data analysis. The system is connected with the group's customer service system, NC financial system, production system, engineering project system and other systems to achieve an integrated information platform for the group's business, customer service and production collaboration. The electronic channel can create a unified electronic channel entrance for the group, including WeChat public platform, WeChat life payment, Alipay, website payment, user APP, etc., and further enhance the brand image and popularity of the group through the unified entrance. Bank collection connects with the banks in the region where each subsidiary is located to realize bank collection. Each subsidiary can set the collection rules independently. The advantages of the scheme are that there are a few group heating enterprises and more than a dozen subsidiaries. The original investment in many sets of software and hardware systems only needs to focus on the construction of a platform, which greatly saves the early construction costs and later maintenance costs. The group control platform is equivalent to the centralized management of the data of the group and all subsidiaries.
