Forestry General Report Form Production System Research And Realization Based On Middleware Technology

With the rapidly develop of computer and information technology and information-based system is widely used, The report form has already became one of the information processing and mutual main method and means in systems such as the office automation and the management information system, the expert system, DSS ,etc.. This subject is based on report form of forestry trade, regarding report form of forestry trade as the breakthrough point will carry on deep analysis and study to the technology of the common report form, have formed the solution of the common report generation system and implementation method finally.The thesis has analyzed to the current situation of the domestic and international report form tool, have pointed out systematic existing problem and deficiency of the report form now at first. Then to the relevant knowledge of the report form, the key technology that the report form tool involves, a technology, XML technology, dynamic SQL technology, database technology, etc. have been analyzed and introduced such as the middle. What we adopted are mostly present major technology and new technology here, making the system more strongly can have the better one the elasticity and expanding. Played the foundation well for the realization of solution of the report form and system too in introduction to the technology at the same time. Finally, how this text has recommended using the technology and report form technology to combine together and make the system be realized synthetically.The processing of the report form has accounted for more than 20 in the common management information system according to statistics, in DSS;unexpectedly the statistical report form is more than 50. At the same time report form part of the one system often again, most apt part that change, increase systematic development and maintenance cost that will be big too. Report form application of system remove from, draw a large amount of report form need convoluted but also easy work by mistake, have improve systematic development efficiency greatly, has reduced the systematic development cost, the more important thing is the report form data with specialized trends, will offer the ocular digital basis for that the policymaker has striven for valuable time, have made the decision with correct science for the policymaker and provided safeguard.The most major characteristic of this tool is that it gives data query rules to users, query freely according to one's own demand by users, according to needing to carry on the design of design of the report form of one's own, will inquire about the design fixed definitely in the function and report form design after breaking through the traditional system. Thus causes the database system dynamic report form the tendency possibly to realize into. Having satisfied users flexible and changeable to the report form, freedom is controlled, real-time and accuratedemand cost that the great too reducing system's running and maintenance cost.The subject uses many kinds of technology to use synthetically promptly, involve and cross the research of theories multi-disciplinarily again, there is certain academic value. The application of this tool can also greatly reducing system's running and maintenance cost. There is good application and practice value.
