Using Python language to write crawler, it is recommended to be familiar with the basic syntax of python, and then in-depth practice
if using Python to write crawler is to meet the needs of "grasping data", it is more convenient to use crawler software, and there is no need to spend time on parsing web pages, testing programs and processing anti collection
it is recommended to use octopus collector, a well-known free crawler software in the instry, with simple operation and powerful functions. Support intelligent anti collection, visual capture process, regular and XPath data extraction, API control and other functions, although the degree of freedom is not as good as python, but the cost is low, can help users put limited resources into more meaningful things

background of Kingdee K / 3 system
Kingdee K / 3 system, as a comprehensive enterprise management solution with financial and business integration, has its profound technical and business background<
first, the improvement of network environment
driven by Moore's law, computer technology has developed rapidly. The CPU has developed from 8088 to P4 today. The network system connecting the world has been built, the network bandwidth has doubled, the domestic Internet access has been upgraded to 56K / s, and the ADSL and cable modem under construction in various places have reached 2m / s, Taking this as an opportunity, enterprise informatization is deeply rooted in the hearts of the people; Enterprise information bears the brunt of the enterprise management network, which requires enterprise management software must adapt to the new network environment< Second, web technology is developing rapidly. Nowadays, the Internet is a global network with 13 million computers and 50 million users, and the number is increasing every day; Enterprises use various tools to publish, share and query information on the Internet as a guide for business decision-making; More avant-garde enterprises have implemented online trading system to rece intermediate costs, and customers can get the most preferential procts in time. It is generally recognized that the prominent feature of the application of web technology in the development of enterprises is that it can "make large enterprises smaller and small enterprises bigger", and minimize the distance between various departments, enterprises and enterprises, and between enterprises and customers. As an important information technology, web technology can arm an enterprise in all aspects of enterprise information management, So that enterprises can break the space restrictions, so that enterprises can freely exchange, manage and use information, develop e-commerce, and integrate internal and external< Third, enterprise groups need to strengthen internal control. The era of large-scale differentiation and reorganization of enterprise groups has come. This is not only the practical demand for enterprises to adapt to market competition, but also a strategic measure to meet the integration of the world economy. The internal control of an enterprise group is different from that of an ordinary enterprise. The subordinate enterprises have different space and different instries. For such a group, more strict internal control and management are needed, including accounting treatment control, monetary fund control, income circulation control, expense circulation control, proction circulation control, financial achievement control, etc, All these need to be managed quickly and effectively through remote tools to achieve the purpose of prior control, so as to further enhance the market competitiveness of enterprises. Just like capital, enterprise data information is also an important resource for enterprise groups. The security, authenticity and timeliness of group data directly affect the decision-making results of the group. Therefore, enterprise groups need centralized storage and management of financial data, regularly or indefinitely review the accounts of subordinate enterprises, summarize consolidated financial statements and analyze financial status, To prevent accounting fraud, the demand of remote data processing and data distributed storage fully reflects the application value of network financial system< Fourth, with the rise of mobile office, the cost of purchasing machine is decreasing rapidly. Most enterprises are equipped with PC on their desks and portable computers for mobile workers. In the busy society, a large number of mobile workers need to work outside the company: at home, in the airport, in the hotel. As an office software for financial personnel, enterprise management software also needs the ability of mobile office. The financial director hopes to check the company's account books anytime and anywhere, and adjust the company's accounts at home; Travel personnel from other places need to fill in the reimbursement voucher in time. When they return to the company, they can directly submit data online< E-commerce has swept the whole world with an irresistible trend, and has become the focus of the Internet and various media. Nowadays, e-commerce is brought into the scope of Intranet and Internet, which greatly expands the initial significance of e-commerce "Internet business activities". Intranet realizes paperless office, office automation (OA), and management information system (MIS / ERP), which makes the capital flow, logistics and information flow of enterprises continue to cycle. The success of American online bookstore Amazon shows that the Internet market is fully capable of supporting large and medium-sized enterprise activities. Intranet and Internet connection, internal information processing and external information processing consistent, is the current sense of e-commerce
the connotation of Kingdee K / 3 system
Kingdee K / 3 system follows Microsoft Windows DNA framework structure, is based on three-tier structure technology, and has graphical form interface (GUI) and browser interface (browser) at the same time, supports network database, and is a real network oriented enterprise management software. It has the following technical components:
"database technology + three-tier structure component technology + web technology + enterprise management technology"
Database Technology: enterprise management software should focus on the data storage system, which is used to store and manage enterprise data. Solve how to store data so as not to lose it; How to store is the most efficient, the fastest and unexpected data automatic recovery. Kingdee K / 3 system adopts large-scale network database management system, supports large-scale user access and massive data storage, and is a variety of large-scale databases, such as MS SQL Server 7.0/2000. Users can choose the appropriate large database according to their own needs
three tier structure technology: enterprise management software is a typical database application, and three tier structure is an advanced and mature database application structure. According to the principle of distributed computing, it divides the application into three levels: database side, middle layer and client side. The database side is the database server; The middle layer contains the computing components that encapsulate business rules; The client is user interface, which can be GUI, ActiveX component or browser
Web Technology: it is a general term for many technologies related to Internet, including security technology, web page technology, electronic transaction technology, etc. security technology is used to protect the data security of server, data security in the process of transmission, etc. Web technology refers to the preparation of web server program that can generate web pages. Users can view and operate financial data in real time through the browser. This technology is a client interface processing technology, which enables enterprise management software to be used on the Internet to meet the needs of remote users. Electronic transaction technology: the realization of electronic transaction, the related technology to ensure the accuracy and confidentiality of electronic transaction
enterprise management technology: including business rules of enterprise management software and means of data processing. Kingdee K / 3 system realizes the perfect enterprise management solution of "data information decision control" through the business and financial management of enterprise logistics, capital flow and information flow
Kingdee K/3 application framework
the advanced nature of software technology directly affects its life cycle. Kingdee K / 3 system is a large-scale database application system based on Microsoft Windows DNA framework and three-tier structure technology. Before the introction, let's take a look at the popular management software application framework in the market
the application frameworks of management software in the current market are diversified, including file server (F / s), two-tier client / server (2t C / s), three-tier client / server (3T C / s), browser / server (B / s), and n-tier structure (NT). The first three are from the perspective of database application, and the last two are defined from the perspective of web development technology, so the former and the latter two are not comparable
enterprise management software is database application first, so it is very important to have excellent database processing performance. The three types of applications are quite different in database processing
file server is the earliest database application structure. Data is stored in specific data files, such as DBF, paradox, access, etc. The biggest disadvantage of this structure is that there is no service program to maintain the data processing, the network performance is poor, the speed of processing network data is slow, when the amount of users or data is large to a certain extent, there will be the risk of data loss, and the data security is not easy to guarantee
two tier client / server is an application developed for large-scale database management system. It follows the data processing mode of the early host system. It makes full use of the inherent data processing ability of large-scale database, improves the speed of data processing, and ensures the security of data. In the structure, the application is divided into two layers: database server and client. In spite of this, the following problems can not be solved in the two-tier structure:
when the number of users increases, the performance of the database will decline. Because, when users connect to the database and begin to process data, a large database management system will establish a connection for each user, which is physically manifested as the occupation of memory. When the number of users increases, the available resources of the database itself will decrease accordingly, so the performance of the whole database will decline
it is difficult to solve the peak assignment problem of computational distribution. In the financial system, there are a lot of calculation processes. If the whole calculation process is put on the database server, it will increase the burden of the database server. If it is put on the client, there will be too much data transmitted on the network, and the processing capacity of the client is limited
its application program depends on a certain type of large database, and users need to change the program or even rewrite it when they change the database type. The portability of the application is not good enough
client programs are closely related to data. If the user needs to change, there will be a large number of programs that need to be modified. It is not easy to meet the needs of users
three tier client / server overcomes all the shortcomings of the above two kinds of database applications, and achieves real distributed network computing e to the adoption of component technology. The three-tier structure includes database server, middle tier server and client
