Abstract


Nowadays,with the market economy highly developed,the demands of the market are ever changing with a great speed,and the competition is becoming more and more intense.Therefore,to heighten the market-response speed and enhance the market-response quality is becoming the objective of more and more enterprises.The remarkable development of high-tech has triggered the adjustment of the world economy’ s structure and the competition in world market will become fiercer and fiercer.What is involved in this thesis is a new model of industrialization.In this model,science and technology play a more important role,economic returns are high,consumption of resources is low,environmental pollution is efficiently checked and the advantages of human resources receive fully utilization.In accordance with the needs of the iron and steel industry’ s integrated management model and the cooperation of supply link between different regions,this enterprise is utilizing, standardizing,rearranging and optimizing the available recourses of the construction of a information-oriented industry and carrying out the overall planning of the blueprint,way of action and timetable of construction of a information-oriented iron and steel industry(including internet infrastructure and information security),and in that process modern information techniques,especially mature managing information technology with the enterprise’ scharacteristics.As a result,the enterprise can adapt itself to its developmental strategy and developmental tendencies in the future and initiate an interaction with the construction of a high quality iron and steel base as well as with the integration and entry into the stock market of the iron and steel industry.The appearance of data warehouse technology enables to build the intelligent information system possibly.This paper is focusing on the research of DW technology and the practical application of the DW life-cycle theory.The process of building the data warehouse based on production management of a steel enterprise is described in detail,with emphasis at the multi-dimension modeling technology.This paper involves lots of DW technology,especially it emphasizes on the data modeling.The main topics of this paper can be summed up as following: Introduction of the paper’ s research background,aim and its structure. Detailed introduction of DW technology,especially data modeling,ETL and OLAP, etc.Basing on the summary of DW theory,the paper expatiates a process of building a DW system about production management of one Steel enterprise.After project,according to the customer’ s need and existing data source,we model, design and realize the whole flow of ETL.At last,the paper shows the design of the whole system and function.Then we use the OLAP technology to show multi-dimension data analysis case of the DW system.At the end of the paper,we analyze the effect of using the product and logistics data warehouse and prospect the future of data warehouse.
