2.4. System database structure
Based on the characteristics of logistics platform operation, the data requirements of its information system must meet the following points:
Consistency of basic data: Some data that must be shared within the company’s logistics network, such as warehouses, vehicles, customers, cargo codes, and employee names, must be consistent. After inputting a service outlet, all other outlets can share this information.
Database security guarantee.
Data query efficiency: In order to ensure the efficiency of the entire company’s internal work, the data query must be obtained within a specified time range.
Multi-database compatibility (for example, Oracle, SQL Server, DB2): Due to the large number of outlets throughout the company, in order to reduce costs, the system must be compatible with different databases. For example, low-performance and low-cost databases are used in some outlets; while in important data centers, high-performance and high-cost databases are used.
2.4.1. Database structure
Based on the current status of the logistics platform, the system database is planned to adopt a centralized database combined with temporary data files from various locations.
The feature of this solution is to ensure real-time synchronization of data in the entire system and unified management of data. But this kind of scheme requires the communication network to have better communication speed, security and stability, in order to guarantee the safe and stable operation of the system and fast processing data. In the event of network problems, key services can still be carried out through temporary data files.
2.4.2. Multi-database compatibility
In order to solve the problem that the logistics information system is compatible with different databases, it is planned to adopt different database plug-ins for different databases. When implementing, you can make the whole system compatible with different databases by configuring the target plug-in at different outlets according to the needs of users.
2.4.3. Data backup and recovery
A good backup strategy is a prerequisite for the normal operation of the logistics platform. For data backup, in addition to dual-system hot backup, the logistics platform can also use a combination of logical backup and physical backup to ensure the maximum possible mean time between failures and minimum recovery time. All backup data is stored on tape And the remote database server. All backups are implemented by writing automatic backup script files or programs through a pre-customized strategy.
Logical backup: Incremental backup of the data of each database at one o’clock in the morning every day (only the business data that occurred that day is backed up). A full backup is made every Saturday morning, and the monthly full backup is used as historical data archive.
Physical backup: There are two types of physical backup (database closed and not closed), namely cold backup and hot backup. Do a full database backup once a month (all tablespace backups), and do a full backup once a week for data with a large business volume. Do one level of incremental backup once a week, including the generated redo log files. Do a secondary incremental backup once a day, and back up the redo logs generated on that day every day.
Disaster recovery strategy: In order to prevent database damage caused by accidents such as earthquakes and fires, all backup data should be stored away from the production database. If necessary, consider establishing a corresponding remote STANDBY database for each database.
2.5. System operating environment
Considering the openness of the system, the system platform is based on the software and hardware environment of the open system, and has a wide range of computer hardware platform support.

2.7. System Security Policy
2.7.1. Three levels of security policy
The security of the network chooses the network version of the firewall, network scanner, system scanner, real-time intrusion monitoring, and Internet antivirus.
The security of the server selects the firewall of the server version, the database scanner, the virus protection of the file server, and the virus protection of the mail server.
Security management selects comprehensive enterprise user management.
2.7.2. Common security strategies
Access Control (Access Control): Measures to restrict unauthorized users from accessing the company’s network and information resources. The access must be applicable to all current services and applications. For example, through Internet services, including Web browsers, e-mail, FTP, Telnet, RPC and UDP, etc. The focus here is on the access control of the server database.
Authentication: In order to provide corporate network resources for local users and various remote users, mobile users, and telecommunications users, in order to protect network and information security, effective authority control and identity recognition must be adopted for accessing connected users. To ensure system security.
User Authentication (User Authentication): Authentication based on the access rights of each user, just like the program of the user LOGIN.
Client Authentication: An authentication method based on the IP address of the client host. The system administrator can decide how to authorize each user, which server resources and applications are allowed to be accessed, and when. How many sessions are allowed to be established, etc.
Session Authentication: Realize client-to-server session authentication through session proxy software.
Encryption: Built-in dedicated encryption and key management methods; fixed key encryption and authentication methods; key management for IP encryption.
Router Security Management: Through a centralized management master, you can configure and manage access control lists on multiple routers. When changing the configuration, you only need to change it in the central management master control, and the system will automatically generate an access control list and distribute the ACL to related routers throughout the enterprise.
Network Address Translation: It mainly prevents the internal IP address of the corporate network from being disclosed. Translate the IP address of the internal network into an IP address that can be used outside, and satisfy that the IP address of the enterprise network can be used and managed on the Internet.
Content Security: Provides data monitoring functions to high-level service protocols to protect users’ network systems and information resources from macro viruses, malicious Java ActiveX applications and Web files containing unnecessary content, and provide the best Improved Internet access.
Connection Control: Server Load Balancing
Record management (Auditing): It can provide a record of users’ activities in the network.
Enterprise-wide Security Management: By providing a centralized security management mechanism, as long as one workstation is used, the network configuration can be controlled in real time while ensuring network security.

Each company’s internal local area network system.
The design idea is as follows: build a data center at the headquarters of the logistics platform company, run the logistics information system, and concentrate all business system data in the data center of the headquarters.
All companies and outlets access the data center through ADSL dedicated lines to perform business system operations. Build Internet dedicated line access at the headquarters to provide Internet “logistics business” services.
2.10.2. System platform technology
Gigabit Network Technology
For the backbone of the data center network, it is recommended to use mature Gigabit Ethernet, high-performance full switching, to meet the needs of large-load network operation.
Gigabit Ethernet is a continuation of FastEthernet. It retains Ethernet frame format, flow control and link layer management, and is fully compatible with Ethernet and Fast Ethernet. With the continuous expansion of the market and the expansion of its own business, the flow of information will continue to increase. The business is carried out in real time, requiring rapid and accurate information transmission. At the same time, the system is divided into levels. The higher the level, the faster the real-time response speed is required. . Therefore, this system recommends that the switch backbone adopt Gigabit Ethernet technology to meet the requirements of large amount of information and rapid response, while also considering the need for system expansion in the future several years.
safety technology
The security of the system is ensured by a variety of Internet security technologies. Related security technologies include firewalls, routers, CA certification, ISL encryption, VPN, etc.
2.10.3. Data Center Network System
The data center network is composed of four parts: the functional server group, the network part, the convergence router part and the Internet connection part.
The functional server group is mainly configured according to the needs of the application system, including logistics information system servers, e-commerce back-end servers, etc.
The network is mainly used as a platform for data transmission, and is the only way for the interaction between lower-level nodes and the database. According to the performance and reliability requirements of the data center, it is recommended to configure redundancy for the core network equipment to ensure that the system can still be uninterrupted even if the core network equipment fails for some reason.
The data center is connected to various companies and distribution centers through routers.
The Internet connection is a link that provides services such as information release, e-mail, and e-commerce to the outside world, and needs to be protected by a firewall.
Key business system-logistics information system server It is recommended to use two IBM PC servers to build a dual-computer hot backup form to build a high-availability and reliable storage system.
2.10.4. Internet security access system
The Internet access part is the link between the logistics platform company’s external information release, e-commerce services and internal access to the Internet, including Mail (external mail service)/DNS, e-commerce websites, firewalls, and routers.
Using DMZ to connect to external mail, DNS and e-commerce website servers, etc., on the one hand, these servers can be protected to a certain extent; on the other hand, even if these servers are broken by hackers, they cannot use these servers as attackers to attack other sites on the Internet. The specific implementation of the tool is to use a firewall to restrict the connection established from the DMZ to the Internet or internal network.
Internet information servers such as Mail, DNS, and e-commerce websites that access part of the Internet are public areas that can be accessed by the intranet and the Internet, and the intranet cannot be accessed by the Internet because it is isolated and protected by a firewall. Intranet can transparently pass through the protective layer to access the Internet. The logical structure diagram of the access part is shown in the figure below.
2.10.5. Headquarters, companies, and distribution centers interconnection system
System interconnection also refers to the connection between each company, each distribution center, and each network point and data center.
The characteristics of the logistics information system determine that it must be connected 24 hours a day.
The interconnection system will be constructed using ADSL dedicated lines, and each network point will be accessed through ADSL dedicated lines. Meet the system interconnection requirements of logistics information systems.
2.10.6. The internal local area network system of each regional logistics center and distribution center
It is recommended to build their own local area networks in each company and distribution center to realize network information office.
2.11. System platform equipment selection design
The equipment selection design is mainly aimed at the related equipment required by the logistics information system: the configuration of the data center logistics information system host, storage backup system and related subsystems.
The host system is mainly configured according to the needs of the application system and provides services for the application system.

2.12.4. Application system security
The security of the application system will be guaranteed by means of logs, authority management, database authority and operating system authority.
Log
By establishing a log in the application system, it is possible to record which modules and access time each operator who uses the system has accessed. This function has a supervisory effect on the operators of the application system, thereby restraining illegal operations to a certain extent.
authority management
Authority management is a system-level security system to ensure that only authorized users can use authorized functions. Authority management usually adopts: user name + password management, the password storage should be binary encrypted, and the user should control the change.
Rights management includes user definition, role definition and user group definition. User definitions describe user information and set passwords; role definitions describe user permissions; user groups define user classifications.
Permission definition can set the use of system functions and operations on data, such as read, write or query permissions.
Database permissions
The database management system also restricts the access role of the database. The usual permissions include roles such as DB owner, DBA, and ordinary user. Each role has different read and write permissions to the database.
Operating system permissions
The operating system also restricts the role permissions of the application system.
According to the business development of the logistics platform, this project is based on the principle of high starting point and accurate positioning. It needs to be completed on the basis of overall planning and design.
At present, the company intends to provide platform rental services for food logistics and clothing industry.
