【正文】 the datalevel, simultaneously requested the processing result will issue thebrowser. It by the Web table list, XML the Web service and the moduleservice is posed. Web table only the application procedurecore is at, it is presents the data and the information foundation tothe customer, also is the information and the data foundation whichthe response and the processing customer and the demonstration Webtable only alternately produces. The data level is provides the digital data service through operation data for business logic level, like the stored datumoperating result, returns to the data retrieval result and so on. visit database principle Is connected with the database, has provided thefollowing 3 ways: Is connected through ODBC。 Direct and SQL Server is connected. 3 ways as a result of theapplication level difference, cause the efficiency from lowly toarrive high, independence from Gao Daodi. Regarding connected databasedata processing, also some 2 ways, namely one kind is isolates theisomerism through DataSet the data pool, another kind is by flows theway to read from the data pool takes (the DataReader way). The traditional application procedure is through first establishes thedatabase the connection, maintains the connection in the procedureentire movement process the way to design. has adopted theseparation connection way construction of data. When browser to Webserver request homepage, the server processes this request, andrequested the homepage transmission for the browser, then theconnection is separated, sends out the next request until thebrowser. The another innovation was has introduced the data set(Dataset). A data set is in the memory provides the data relationschart the high speed buffer. The data set knows nothing about to thedata pool, they may or through call in the data by the procedure fromthe data warehouse to produce, the packing. No matter the data fromwhere gain, the data set all is operated through the use similarprocedure template, and it uses the same latent data buffer. 2 systems functional designs systems function structures This news management system management system may operatingsystem platform move in Windows in 2,000 Server, the Web server isIIS, the database server is Microsoft SQL Server2020, Microsoft VisualStudio which the development kit uses NET and DreamWeaver.
