System Analyzeing Sample Sample Sample Sample Site Gold Card Engineering Jiangsu Joint Office Eugene No. 242 Zhongshan South Road, Nanjing, Jiangsu Province No. 242, South Road, Zip Code: 210005 Tel: 4209423) On the establishment of an intranet of intranet, in recent years, the Internet Internet Internet Internet Internet is popular in society, and the advancement of Internet technology is widely concerned. Therefore, using the idea of Internet technology, it is applied to the enterprise LAN (LAN), and the intranet of an enterprise is set up in the Internet. On the Internet, it is now called annet. As a technical backbone of the information center in a unit, I am fortunate to complete the overall plan design independently, organize the construction of the intranet of the unit and undertake part of the software development. After the program is implemented, the original business application system is integrated, and the internal information distribution system and FTP file transfer system are established, and network interconnects are implemented with the subordinate units, realizing information sharing between each other, and utilizing VPN technology using Internet The network can access the Intranet of the company. Some methods and strategies in this project will be implemented as follows, I hope to be inspired by the Intranet network to form SMEs: Basic situation: 1. Application unit: A foreign transport group is transported in a port foreign trade Enterprise, is a business partnership, a branch of the group's distribution, undertakes the transportation agent of import and export goods, and transfers the document of import and export goods to the main cooperation logistics to customer service as the main business. 2, computer application: The current enterprise has a city network, NT 4.0 platform, and the core application software is a network multi-user system developed by the container transportation agency business system. There are other personnel, finance, statistical software, office software (Office). There are 4 special computer applications. The implementation of the intranet network of this unit is mainly based on the needs of information flow within the system. In the process of the implementation, we mainly carry out the following strategy selection: 1. Network construction plan: the unit originally a city network, 25 information points. But with the high requirements of information construction, it has not been able to meet the needs. There are 6 layers of office buildings in the unit, requiring human hand, while requesting with three grassroots units (fleets, foreign warehouses) and a container station. Leadership, middle-level cadres, etc. are required to have corresponding data and various queries. For this unit, the comprehensive wiring project was first carried out in the office building. Due to the small office building, the plan for concentrated lines was used, using a 5-class line, 100M bandwidth, 125 information points. The switch uses a 12-port 3CM 3C5092A 10 / 100M adaptive device, and the shared HUB uses several 3com 16-port HUB. The Cisco 3600 is used as a router. 4 wide-area network ports are connected to 4 remote base units and box stations, which use dial mode. The combination of frame relay FR is connected to Beijing Headquarters (because of funds, there is no application for the time being). Since the unit is mostly the PC, there is a huge Windows user group, so the network platform also uses Windows NT4.0. The infranetic protocol TCP / IP is used as a network protocol. In addition, the main interculve, the main work between the office building is used to make the main duct, the main work between the main work, and the main work is performed.
If there are several buildings such as campus network, the fiber can be used to do the main network (FDDI), and P & S wiring is implemented in each building. 2, the selection of software platform: The current popular intranet platform, A, Based on UNIX, B, Linux (OS) C based on Linux, based on Microsoft Platform Windows NT. Taking into account the characteristics of SMEs, there are more third-party software for choice, supporting the software vendors of Microsoft platforms and convenient users to operate, GUI interface and other factors, we have chosen Windows NT4.0 as a network operating system, with itself Equipped with IIS4.0 as a web platform, IE4.0 browsing the platform as a customer intranet online. Compared to large databases such as Sybase, Orcale, Informix, DB2, SQL Server is a small large database with NT platform and excellent cooperation. For small and medium-sized enterprises, it is natural to choose SQL Server6.0 as a database platform. In addition, it is also very popular with Linux platform technology. It is also fully competent from technical talks, just considering learning to be broken. And the user's acceptance ability is not used. 3. Because of our own technical strength, and in the face of the trade in the foreign industry. We intend to develop some web applications on intranet. Development platform with Visual Basic / Front Page / HTML Editor, Develop some interactive web applications, and collect data for the original application system. Need to master the corresponding interactive development technology and technology connected to the database, such as CGI (Public Gateway Interface), API (Application Programming Interface), ASP (Active Server Page), ODBC (Open Database Interconnection), RDO / ADO ActiveX Data Object Active Data Objects). In the above techniques, considering response speed and efficiency, I recommend developing ASP plus ADO technology. And this is the mainstream development technology of the current and future Internet / Intranet network. 4, interoperability and safety considerations of the internal network: due to the small and medium-sized enterprises, the number of concurrent users in the Internet generally will not exceed 15 people, we use a relatively low ISDN-wire way, special one PC Installing the proxy server software (Proxy), you can make a fast buffer with a high-demand dial, HTTP proxy, FTP proxy, telnet proxy, SMTP / POP mail agent, user management, etc. Of course, use DDN mode, the way to apply for legal IP addresses is also possible, but it is only due to the reasons for funding. Due to the interworking of internal and external networks, if there is no certain security mechanism, the company's internal data, machine, application system are attacked or unauthorized by viruses or hackers. Safety technology between inside and outside has a package filtering, firewall, security agent service, etc., because we have some security measures for the agent software software that have some security and internal data security measures, management systems, and backup mechanisms. Therefore, there is no more funds in this regard. On the internal LAN, we chose NET VRV (50 users) network version of anti-virus software, and the corresponding version is installed in the server side and the client, ensuring the security and reliability of the internal network. Currently, there are many companies that are network security, such as Wang Jiangmin's KV series, Rising Company, etc. can be selected. 5, the original integration of the system and intranet technology: Since the original application system is based on FoxPro, the database is the file type database, the selected web application development environment does not directly operate the FoxPro database. In this regard, we have additionally prepared a software to import the managers from the application to the leadership data into SQL Server from the application, and prepare a web interaction query system with SQL ServR.
