D: the gateway server end is packaged into the xml message with execution result with Web Service form and returns to the driving client, drive client with the format analysis of xml message that receives with Web Service after, extract the result.
Below in conjunction with Fig. 1, Fig. 2 the remote access method of the database that the embodiment of the invention provides is made concrete introduction.
As shown in Figure 1, in the remote access system of entire database, the embodiment of the invention has comprised application program, has driven client, gateway server end and database, it is understandable that, at the gateway server end.The gateway server end is that the J2EE Web of standard uses, and is responsible for and drives communicating by letter of client, and realization is to the operation and the inquiry of the remote access database of needs.System's installation requirements are following:
Operating system: Windows XP, Windows Vista, Windows 7, Windows 2003 Server, Windows 2008 Server or Linux (version after the kernel 2.2)
JDK?1.6
Database: Oracle 8i, 9i, 10g, 11g, SQL Server, MySQL 4 or MySQL 5
J2EE application server: Tomcat, JBoss, Glassfish or WebLogic.
Driving client is the JDBC driver of standard, under the JDK1.6 environment, can well move.Application program can be driven client call by the standard interface of JDBC, realizes the visit to remote data base through network.
As shown in Figure 2, at first execution in step 101: application program drives the driving of client through unified API Calls.API (Application Programming Interface; API) is some predefined functions; Purpose provide application program and developer based on certain software or hardware to visit the ability of one group of routine; And need not to visit source code, or understand the details of internal work mechanism.Application program described in this step is the application program that the third party develops; This application program can be in operating system drives the driving of client through unified API Calls; And then startup drives the operation of client; For the ease of operation, this application program can be designed as the visualized operation interface, and operating personnel in the interface, import request instruction through visual operation interface or the instruction of other associative operations gets final product.
