1. Six elements of national information system: eagle (application) and chicken (technology), left benevolence (talent) and right corner (specification).
Leading application (leading application of information technology)
Core resources (information resources are the core tasks)
Basic network (information network is the foundation and necessary means)
Target industries (information technology and industries are the purpose of information construction)
Successful talents (information talents are the foundation of success)
Safeguard norms (information policies, regulations and standards are fundamental guarantees)
2.2 characteristics. ERP: Primary Imitation -one (Unified) Process (Business Process Oriented) Module (Modular Configurable) Imitation (Open)
3. The characteristics of data warehouse: the ancestral home is variable-the ancestral home (subject-oriented) is variable (integrated) (non-volatile) (changing with time).
4. The main contents of information system service management in China:
The second unit and the second personnel are system integration and supervision (computer information system integration qualification, information system engineering supervision unit qualification, information system project manager qualification, information system engineering supervision personnel qualification).
5. Four controls, three controls and one coordination: qualitative change of input, safety and trust, plus communication and coordination (input cost, schedule, quality, change, safety, information and contract).
6. Life cycle of information system: Bloom Cloud disappears and is divided into testing (project establishment, development, operation, extinction, planning, analysis, design, implementation and acceptance).
7 Software maintenance: just fish balls (error correction, adaptation, prevention and improvement)
8.UML diagram:
Static picture: the troops are tired into dogs!
Static-troops (pairs) are (complex) packaged into dogs (structures) (deployment diagram, object diagram, composite structure diagram, package diagram, class diagram, structure diagram).
Dynamic diagram: create traffic along the pile and use it flexibly (imagine turning the pile upside down in the car test)
Dynamic traffic planning and flexible use along the pile (product diagram, sequence diagram, interactive overview diagram, communication diagram, sequence diagram, state diagram, activity diagram and use case diagram)
9. Relationship between use cases: including habits (including expansion, association and generalization).
10. The relationship between classes: the cock's comb gathers a lump of shit (inheritance, association, aggregation, combination, dependence and realization).
1 1. Steps of object-oriented analysis: (hair color example, build use case analysis, build customs clearance function) Discover role participants, find use cases, build use case models, conduct domain analysis, build object-relationship models, build object-behavior models, and build object-function models.
12. Common frame memory:
Low performance of pipeline black box and object-oriented modularity
Event-driven thinking, graphic hierarchy, mode of thinking, seven layers.
The knowledge model responds faster than the blackboard C/S model.
B/S mode is easy to maintain.
13.J2EE runtime environment: components are codes, containers are environments, and services are interfaces.
14. computer network IEEE802
802.3 (Ethernet Protocol) 8024 (Token Bus Network) 8025 (Token Ring Network)
802.6 (people)-4 in total, 5 in the ring and 6 in the city.
15. Project features: temporary, unique and gradual.
16. Characteristics of project objectives: excellent multi-level (priority, multi-objective, hierarchical)
17. The core content of the project proposal: the necessary market scheme conditions (the necessity of the project, the market forecast of the project, the market forecast of the product scheme and service, and the necessary conditions for the project construction).
18. content of feasibility study: speculative talent group and warning wind (investment, technology, finance, organization, economy, society and risk)
19. Detailed feasibility study methods: inferior products, investment and evaluation to increase benefits (economic evaluation method, market prediction method, investment estimation method, incremental net benefit method).
20. Description of project scope: Lunar New Year holiday (project and scope objectives, product scope description, project deliverables, project boundaries, product acceptance criteria, project constraints, project assumptions).
