The OLTP system can not afford the demand of decision support due to the drastic commerce competition, so the appearance of OLAP technology is importanct. The key technical of OLAP, the classical resolvent of data warehouse and the methods of data preprocessing are studied. A frame of parallel data extraction interface for commercial OLAP is proposed. Data preprocessing technology (data cleaning, data integration and transform, data reduction) connected with the frame is practically studied and applied. The eficiency and the practicality of the frame are illustrated by practical application.  相似文献

According to the urgent need for motorcycle parts enterprise to improve the ability of information exchange and business collaboration between the production process and other links such as the marketing, design, production planning, outsourcing, purchasing and delivering, an integration framework of the intergraded workshop production management system for motorcycle parts enterprise is presented. It can be integrated with the designing and production planning management systems upwards, the workshop equipments and workers downwards, and the subcontract production and supply chain management systems outwards. Then, some key technologies are studied, such as the realization scheme of system integration based on Service Oriented Architecture (SOA), the data integration and sharing mechanism of heterogeneous information system based on eXtensible Markup Language (XML), and the real-time interaction technology of workshop information based on the multi-functional interactive information terminals, etc. Finally, the system is developed and successfully applied in a motorcycle parts enterprise, and good results are obtained.  相似文献

By analyzing the process of enterprise information engineering construction and intra relationship among information system requirement, business process modeling, application system constructing and project management, one of 4 meta model composed of requirement engineering, process engineering, application system engineering and support engineering is proposed for enterprise information engineering. The developments and applications of the business processes and its application systems are integrated into the same development space and application space. Basing on this, a prototype system composed of requirement modeling environment, business process modeling environment, application system modeling environment, and support engineering environment has been designed and built, which is used for supporting enterprise information engineering constructing. It is valued for the enterprise information engineering construction in our country.  相似文献

The article analyzes the basic constitutes of enterprise salary in our country by applying the theories of HR. As the characteristics and functions of the basic constitutes are different from each other, the article mainly discusses the obvious salary, then gives the related expression and the chart between salary and its elements. Aiming at the main problems which are average, short-term and single in enterprise salary at present, the author probes that enterprise salary will be market, long-term and diverse under the knowledge economy by applying the salary frame, the theories of stock options and employees' needs.  相似文献

Along with the widely using of mobile telephone, the SMS (Short Message Service) has achieved more and more approbation of consumers. Besides the point-point application of SMS among mobile phones, a new application of SMS between information system and mobile phones is developed quickly now, and it is a new way to achieve information conveniently and duly for users. In this paper, we design a software based on SMS to solve some problems which exists in the communication among employees. We also give out the system's functions, key technology and application in the enterprises. This system has some important value in theory and application for building a digital enterprise.  相似文献

Analysis and forecast for market have become important methods of making decision in most enterprises. It is the base of analysis and forecast to effectively store and make full use of the data in the distribution. Technology of data warehouse and OLAP provides the strong function of storing and integrating data, and mathematics methods provides a series of statistics and analysis tools. Combine IT and mathematics methods in the field of analysis and forecast for the data of distribution to put forward a design and implementation plan of application system in supporting decision based on data warehouse. The design exhibits the processes how to build data warehouse and multi-dimensional data, recommends the methods of analyzing and forecasting, and shows a good integration of advanced information technology and decision science.  相似文献

Rice improvement is based to an increasing extent on ever-sharper genetic analysis to the detriment of classical breeding, which is disappearing. Analytical genetics are very promising, but they cannot replace integrated and finalized breeding. Little attention has been paid to improving participatory rice breeding methods for subsequent integration into sustainable cropping systems. Special methodological initiatives are required to ensure the success of this breeding-agronomy integration. This integration of inexpensive breeding methods has increased the biodiversity of rice: low temperature and drought tolerant upland rice varieties for mountain areas, and polyvalent varieties, which have the ability to grow in both rainfed or irrigated conditions, they are perfectly adapted to improved cropping systems and to beneficiaries’ needs and preferences. These preliminary results on this integration demonstrate that the present approach is relevant.  相似文献

针对安徽省设施番茄生产中肥料施用量大、施肥方法不科学等问题,以安徽省芜湖县设施番茄为研究对象,探讨水肥一体化措施下减量施肥对番茄产量、产值、品质、养分吸收和氮肥利用效率的影响,以期为区域设施番茄合理水肥管理提供理论和技术支持。研究结果表明:与菜农习惯水肥管理相比,水肥一体氮肥减量20%-40%或氮磷钾肥各减量20%都能够提高番茄产量、产值和利润;影响番茄品质因子较多,在本试验施肥量下,水肥一体减量施肥番茄可溶性总糖、可溶性固形物含量下降,Vc含量增高,适当减少肥料用量有利于番茄红素含量的提高,减肥幅度过大,番茄红素含量下降;水肥一体减量施肥能提高氮肥当季利用率。综合番茄产量、品质和氮肥利用效率,在本试验条件下, N 240kg/hm2、P2O5 144 kg/hm2、K2O 240 kg/hm2 是较为合适的用量。笔者认为,尽管优化施肥、水肥一体化减量施肥能提高氮肥利用效率,但设施番茄的氮肥利用率仍较低,氮肥利用率的提高仍有一定的潜力。  相似文献

Performance-based seismic design involves how to confirm inelastic displacement demand of structures under earthquake in concise and reasonable way. Two shortages need to improve in analyzing the elastic-plastic seismic responses of structures if the traditional capacity methods are employed. The shortages are the uncertainty of equivalent high damp of elastic-plastic structures and the limitation of the higher order vibration mode effect being not taken into account. To solve these problems, the authors propose the concept and analyzing process of improved capacity spectrum method based on modal pushover analysis and the elastic seismic responses spectrum modified by strength reduction coefficient and ductile coefficient. The example of analyzing the performance of frame structure is shown which may be a simple and effective method used in engineering. This method has application potential in Performance-based seismic design.  相似文献
