Information Resource Planning, Abbreviation IRP
1. Information resource planning refers to the comprehensive planning of the collection, processing, transmission and use of enterprises and institutions or government departments. Its core is to use the advanced information engineering and data management theory and method of Western countries, through overall data planning, the basis of data management and resource management, to promote integrated application development.
2. In terms of practice, information resource planning is engineering technology, including demand analysis, system modeling, support tool, etc. The process of performing IRP is the company's business process, find information requirements, establish corporate information standards and information system models; use these standards and models to measure existing information systems and various applications, in line with inheritance and integration, Reconstruction optimization, purchase or re-development is not met.
3. To truly realize the flow, sharing, and application of the company's internal and external information, the most basic, most important issue that needs to face - through the overall data planning, rich information, rich information, and updated a timely shared database.
4. Information resource planning can be mainly summarized as "establish two models and sets of standards". "Two models" refers to the functional model and data model of the information system, "a set of standards" refers to the basic standards of information resource management.
5. The significance of doing a good job in the planning of information resource is: (1) Helping genre and standardizes expressing user needs, implementing "application leading". (2) Integrate information resources to eliminate "information island" to achieve application system integration.
(3) Guide the selection of application software such as SCM, ERP, CRM, and ensure successful implementation.
6. The basic core of the Information Resource Planning (IRP) is Information Resource Management (IRM). The goal of information resource management is to increase management efficiency by enhancing the ability of information in information on information, internal and external information, that is, pursuing "3E" - Efficient, Effective and Economical.
7. The so-called information resource management base standard refers to the quality of the information system, and is also the most basic standard for information resource development and utilization. According to the previous theory and our research, summarize the basic standards for information resource management: data element standards, information classification coding standards, user view standards, concept database standards, and logical database standards.
8. Data Elements is the smallest non-divided information unit, which is a general name of a type of data. Information classification and coding is a field of standardization, has developed into a discipline, has its own research object, research content and research methods. User View is a collection of data elements that reflects the end user's views on the data entity.
9. Concept database standards and logical database criteria refer to Subject Database. The concept database is a summary of the data required by the business, and the logical database is the data structure for analyzing designers.
10. The theme database is not a documentary report, but a data organization for business topic.
11. The information resource planning is to conduct business analysis, to re-recognize the enterprise in order to systematically, essentially, generally, and generally grasp the functional structure of the enterprise. This is what people often say "business card". According to the methodology of information engineering, we use the three-layer structure such as "Functional Area-Business Process-Business Activities" to comb, this is the business model.
12. Function Area is an abstraction in some major business activities in the enterprise, rather than moving in the existing institution. Each functional domain contains several business processes (Process). Each business process contains a number of business activities, which are basic and unreplified business units. 13. The process and activity of the computer interaction will be processed by the computer, and the "Subsystem-Function Module-Programmm Module" is organized, which is the system function model (Function Model).
