In response to the choice of architecture for Beijing Electricity Material Management System, you should pay attention to the following problems:
N ???????? The user is wide. Beijing Electric Power Materials and its related users are dispersed in different locations, the basic information facilities are different.
N ???????? Different in the form of information. The company's departments, related units, structured data and unstructured data coexist, shared information, and information coexistence. Since Beijing Electric Power Material Company and its related unit structured data account for only part of corporate information and knowledge, the non-structured data is full of company's work. For company decision makers, it is often a memorandum, an email These "dead angles" have hidden very important information resources. From the current situation, there is a lack of effective means to effectively organize these structured, non-structured information, corporate and project groups.
n ???????? Suitable for the business flexible adjustment. In order to meet the changes in the market, Beijing Electric Power Materials requires time to adjust the business process and organizational process, how to make this more business, organizational adjustment quickly to the system, is Beijing Electric Power Material Company Material Business Important content of platform system construction.
We believe that the three-story architecture can effectively help Beijing Electric Power Materials Management System to achieve application needs, and can achieve high scalability with online fast and convenient expansion of online flights or increased users The goal of the construction of network procurement platform.
3.2 Technical route and application architecture selection
J2EE is an architecture using Java 2 platform to simplify the development, deployment, and management of business solutions. The basis of J2EE technology is the standard version of the core Java platform or Java 2 platform. J2EE not only consolidates many of the advantages in the standard version, but also provides EJB (Enterprise JavaBeans, Java Server Pages), and XML. The comprehensive support of technology is an architecture that enables enterprise developers to significantly shorten the market time.
The J2EE architecture provides an intermediate-level integrated framework to meet the needs of applications that do not require too much cost and require high availability, high reliability, and scalability. By providing a unified development platform, J2EE reduces the cost and complexity of developing multi-layer applications, while providing strong support for existing applications, fully supporting Enterprise JavaBeans, with good guidance support packaging and deployment applications, add directory support , Enhance the safety mechanism and improve performance. 3.3 Data Planning and Database Design
Enterprise information system construction focus is the overall data plan, in fact, combining corporate planning and business analysis, with the establishment of data models and functional models.
The database is the core and foundation of the information system. It organizes a large amount of data in the information system to organize a certain model, providing functions of data for storage, maintenance, search, so that the management information system can be convenient, timely, accurately from the database. Get the required information. Only a reasonable design of the information system's database can be developed to develop a perfect and efficient information system. Database design is an important part of information system development and construction. It belongs to a complex, huge information engineering category. Based on the overall analysis of the system, based on the needs of the system information system, the Data Stream and Data Description Dictionary is described as a concept description, the description and conversion of logical mode and data model.
3.3.1 Database Design Method
The entire database design is divided into four phases: demand analysis (analysis of data and operational processes for management information systems), concept design (information analysis and definition), logic design (design data model) and physical design (physical database design).
3.3.2 Combined design strategy of database and application system
Beijing Electric Power Management System Database Design is the information engineering theory combining database and application system, which combines structural (data) design and behavior (processing) design in the entire design process, which combines data and function analysis. Design method, this combination of design strategy is to synchronize data and processing, collect, analyze, abstraction, design, and implementation, etc., with each other, replenish each other, to improve each other, to improve two aspects .
3.3.3 Conceptual Design and Logical Structure Design
The main task of the concept is to describe the Data concept structure independent of the DBMS of the data logic structure and support the database. It is an analytical method using an entity-contact, and the content (DFD, DD). Abstraction, classification, aggregation, and summary, extract the entity, entity of the subsystem, identify the code of the entity, determine the contact between the entities and the entity, plot the basic ER diagram. Through the abstraction of the real world, the ER map tool is used to describe the entity and contact, and then the integration of the view is performed on the local view, eliminate collision and redundancy (except for individual necessary redundancy), formation The basic ER diagram of the subsystem is a conceptual description of the common characteristics in the real world.
The task of logical structural design is to convert the conceptual structure into a process that meets the data model supported by the selected DBMS. Since the database management operating system selected by Beijing Guodian Business Network is an Oracle's relational DBMS product, the management subsystem logical structure design is the relational data supported by the concept structure (basic ER figure) model to Oracle? DBMS. model.
3.3.4 Share Data
The database is the core of the management information system. We designed the database as much as possible approach the information source and the use point, and it is close to use. Reduce unnecessary circulation processes to ensure smooth information channels. We divide the data into shared data and private data. Private data refers to data dedicated to subsystems, only subsystems, and manages and maintained by subsystems. Sharing data refers to data for global sharing for data for each subsystem. By analyzing the data of each subsystem, we extract critical data in each subsystem, and store them in public databases for integrated queries and other subsystems. Shared databases mainly include products, manufacturers database, various commercial exchange databases (such as a price list, order), etc. For shared data extracted from each subsystem, the shared data is sent to the public service library in different ways (including programming write interface, promotion, view, etc.). Shared data provided by each subsystem, maintained by subsystem, and each subsystem maintains its own share data according to the operator's permissions, and sending the shared data to the server in time. Ensure the correctness of the data, increase the security and consistency of data. 3.3.5 Target
Establish and plan the business framework of the entire material system, including business models, business process models, and data models, and refer to the existing system to make basic system models, based on the established model, the construction framework and norm of future systems are extracted, and the business is determined. Process and data store the division of labor and distribution of different systems, and distribute data interfaces between global systems, as well as system future programming and interface technology implementation, providing a variety of system-transformed strategies and implementation steps, thereby constitute Complete data resource integration scheme.
A unified plan is made for issues affecting data sharing between data specifications, data formats, coding rules, and business descriptions between individual systems. It is technically addressing a variety of operating system platforms, database platforms, and technology platforms to achieve data sharing. And business integration specific solutions for guiding the improvement and development of various systems in the future, as well as the construction of system platforms, fundamentally solving data sharing and integration requirements between different systems.
3.4 Power Material Code Specification
Product unified code coding specification refers to the organic overall organic overall, unified assignment, unified management, unified maintenance required for products and its related information, and is integrated with the organic overall, and Its related information is uniquely identified throughout its life cycle. Among them, it is the key to formulating a product unified code.
This project hopes: through the analysis, research and summary of the unified code of the relevant products, combined with the application of the actual and application needs of Beijing Power Company, formulate the company's unified standard, guide and regulate the company's electricity product code, to achieve the product Information sharing, reducing cost, and improving efficiency laying the technical foundation.

4. System security plan system
4.1 Security Scheme Design Principles
* The principle of demand, risk, cost balance
* Comprehensive, integrity principle
* Principle of availability
* Step-by-step implementation principle
Based on the above idea, the network information security system should follow the following design principles:
4.1.1 Missing the level of grading management requirements of the Internet
??? According to the Internet network size, many users are characterized, the INTERNET / INTRANET information security implementation of grading management solutions will implement security management.
Central network, mainly realizing internal and external network isolation; access control of internal and external network users; internal network monitoring.
Terminal / Personal User-Level, implement access control of internal network; security protection for database and terminal information resources.
4.1.2 Principles of demand, risk, cost balance
For any network, absolutely safe is difficult to achieve, nor necessarily necessary. A network of actual research (including tasks, performance, structure, reliability, maintenance, etc.), and analyzes the threats of the network and the risk of qualitative and quantitative risks, and then develop specifications and measures. Determine the security policy of this system. 4.1.3 Principle of Comprehensive, Integrity
Application system engineering views, methods, analysis of network security and specific measures. Safety measures mainly include: administrative legal means, various management systems (personnel review, workflow, maintenance system, etc.) and professional measures (identification technology, access control, password, low radiation, fault tolerance, anti-virus, high security Product, etc.). A good security measures are often a suitable application result for a variety of methods. A computer network, including individuals, devices, software, data, etc. The status and influencing effects of these links in the network, and only see the overall angle of the system, and analyze can be effective, feasible. That is, computer network security should follow the principle of overall safety, and a reasonable network security architecture is established according to the prescribed security strategy.
4.1.4 Principle of availability
Safety measures need people to complete, if the measures are too complicated, too high to people, it itself reduces safety, such as key management has similar problems. Second, the use of measures cannot affect the normal operation of the system, such as a cryptographic algorithm that greatly reduces the operating speed.
4.1.5 Implementation principles: grading management, step-by-step implementation
Due to the network system and its application extension, with the expansion of the network, network vulnerability will continue to increase. It is unrealistic to solve cybersecurity issues in one another. At the same time, due to the implementation of information security measures, it is considerable expense. Therefore, the basic demand for network systems and information security can be saved in step-by-step implementation, and cost expenses can also be saved.
4.2 System of security system design
The computer network is a hierarchical topology, so the security protection of the network also needs to adopt a hierarchical topology. That is, a complete network information security solution should overwrite all levels of the network and combined with security management.
The security level of the network is divided into: link security, network security, information security
The security level and safety measures taken at the corresponding level are shown in the table below.
information security
Data transmission security (dynamic security)
data encryption
Data Integrity Differentiation
Defare reputation (digital certificate, digital signature, timestamp)
Security management
Data storage security (static security)
Database security
Terminal security
Leviness of information
Information content audit
User authentication security
Identify
Authorization (CA certification)
cyber security
Gateway anti-virus (firewall)

(Anti-virus software, intrusion monitoring)
Access and access control
Safety policy for operating systems, databases
Monitoring and log auditing
Link security
Communication encryption
???????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????
As can be seen from the above table, the system's security system includes 8 aspects of content, namely monitoring and log auditing, access control, communication encryption, digital signature, gateway anti-virus, network security detection, risk prevention, operating system and database security Strategy.
4.3 Data Backup and Recovery
????? The necessary one is essential in the security construction of network system is the regular backup and historical preservation of data. There are two mainly two-to-date backup purposes: First, the business data of the production system can be restored to the production of data locally due to system or human error operation, and can be restored in the production of data locally. Another purpose is to occur in a regional disaster (Earthquake, fire, machine is destroyed, etc.), data and disaster recovery of the entire system can be achieved in a local or different site in time.
?????? The ideal backup system should be all-round, multi-level. First, use hardware backup to prevent hardware failure; secondly, you should use a professional backup software system to back up important data; at the same time, a special backup policy is to be developed. Thus, even if the data is logical damage due to software failure or human malignone, the network storage backup system and hardware fault tolerance are used. This combination forms a multi-level protection for the system, not only can effectively prevent physical damage, but also thoroughly prevent logic damage. ?
