The Research And Realization Of The Web-Database Development Module Based On Middleware

Base on the research of WEB Data-Base Middle-wares, the author chooses JDBC as the research object. The author points out some problems that exists in the course of JDBC development of WEB database, and puts forward the suggestion of improving.First The author puts forward using the mode of MVC to reconstruct the whole framework of the WEB database development package, encapsulate the Course of the joining the network data base, in order to meet the requirement of OOP and improve the shortcoming. In addition, because ResultSet type uses tediously, the author proposes two kinds of substituting types: String[][] type and Data type which is inherited from Hashtable type.Through careful analysis and design, authors realize two kinds of improvement described above, and realize the WEB database development package which is based on the MVC Mode. The programmer can use this package to develop the procedure easily. The programmer can get String[][] type and Data type from ResultSet type directly, so can save the complicated operation of ResultSet.Finally, authors finished a simple WEB-procedure, and use it to examine the function of the WEB database development package. Through complete analysis and design, this WEB-procedure has been basically finished the test of different performance of the WEB database development package. The result proves that, various performance of the WEB database development package are finer, the response to the various operation can be very good.
