Embodiment
The present invention will be described below in conjunction with accompanying drawing.
As shown in Figure 1, the user oriented data base management system (DBMS) of the present invention comprises background data base 1, management platform 2 and client 3, is provided with ADO (ActiveX Data Obiect) interface 21, data management module 22, database application catalogue 23, configuration information module 24, querying condition administration module 25, query statement editor module 26 and intelligent integrate module 27 in the management platform 2.Wherein domestic consumer uses client 3 to conduct interviews by 2 pairs of background data bases 1 of management platform, selects querying condition in the drop-down menu of user by client 3 display interfaces, realizes the operation of inquiry and analysis data; Management platform 2 is provided for the display interface of data management, inquiry and analysis to client 3, has avoided domestic consumer need to edit the querying command of based on database grammer; The keeper can be to using domestic consumer's setup and use authority of client 3 on management platform 2, and the setting in the management platform 2 can't be revised by domestic consumer.ADO interface 21 is OO Universal Database access interfaces of Microsoft development data storehouse application program, characteristics with highly versatile, can make management platform 2 be connected to Access, dBase in the background data base 1, Oracle, SQL Server, the current common Database Systems such as Visual Foxpro, MySQL, can realize that also management platform 2 manages a plurality of different background data bases 1 simultaneously.
Data management module 22 is undertaken alternately by ADO interface 21 and background data base 1, so that the keeper can be preset at the database application in foreground and background databases 1 in platform database 1.Wherein database application is the stored items of data in background data base 1, and such as tables of data such as spun yarn output statistics table, spun yarn statistic of attribute tables, the function of database application depends on keeper's setting fully.According to the content of database application, can preset a plurality of database applications in the background data base 1, each database application also can connect a plurality of different background data bases 1 simultaneously.Database application catalogue 23 is used for managing the database application of above-mentioned database management module 22, adopt the mode of directory tree to show rating information and the hierarchical relationship thereof that disparate databases is used, and client 3 is set the authority that the access disparate databases is used catalogue; The keeper of management platform 2 can freely increase, deletes and manage different database applications, such as data typing module, data query and the functional modules such as data analysis, chart.
Be provided with independent configuration data for each background data base 1 in the configuration information module 24, be used for the relevant configuration information that the storage current database is used, according to the difference that arranges, can realize multiple different database management function in client 3.Client 3 is before opening a database application catalogue or database application, to from the configuration information module 24 of management platform 2, read the relevant configuration data first, dynamically generate afterwards user's query interface of client 3 in client 3, needed querying condition can be selected by the drop-down menu of user's query interface by domestic consumer.Configuration data adopts similar standard I ni file structure, configuration data comprises Database Connection Parameters 241, grouping variables set 242, conditional-variable collection 243, main query statement collection 244 and Query Result display parameter 245, and Query Result display parameter 245 can be divided into tables of data display parameter and chart display parameter.
Stored the link information of the background data base 1 of the correspondence that current database uses in the Database Connection Parameters 241, system can arrange simultaneously a plurality of different background data bases 1 and connect, and each independent database application optionally uses these connections.
Store a plurality of different conditional-variables in the conditional-variable collection 243, comprised conditional-variable name sequence and corresponding argument sequence group thereof.Conditional-variable comprises variable name and argument sequence, and each conditional-variable can arrange separately argument sequence wherein, and these parameters include: data type comprises character type, numeric type, logical type, date type etc.; Display label comprises information; Default value comprises the acquiescence displayed value; The drop-down list parameters comprises that the tabulation set pair answers displayed value tabulation, whether read-only arrange etc.; The control size; Display position etc.The keeper can freely define the querying condition setting that shows in client 3 drop-down menus in conditional-variable collection 243, the querying condition that shows in conditional-variable and the client 3 user's query interfaces is corresponding one by one, and system dynamically generates dissimilar controls according to the data type of querying condition.If character type data, what then querying condition was corresponding is a drop down list control, conditional-variable can be set to independently query statement, the list content that therefore can satisfy condition according to the as a result Dynamic Generation that other querying condition is selected, and can not show garbage.
Stored a plurality of different grouping variablees in the grouping variables set 242, comprised grouping variable name sequence and corresponding two parts of variate-value sequence set thereof, the variate-value sequence is made of a component group variate-value.The order of variate-value sequence set is pressed by system when inquiry, successively the grouping variate-value in each variate-value sequence is updated in the main query statement, and all grouping variable names are replaced to corresponding variate-value.Each component group variable name is carried out a subquery statement, and system carries out successively many group subquery statements and obtains final Query Result set, at last Query Result is integrated demonstration.Variate-value corresponding to grouping variable name is made of character string, can comprise query grammar, so dirigibility is strong, can remedy the query demand that the single query statement can't be finished.
Conditional-variable is with designated symbols “ ﹠amp; " start (with “ ﹠amp; Bian Liangming ﹠amp; " expression); represented that domestic consumer is selected or the parameter value corresponding to querying condition of input; when domestic consumer when client 3 has been selected a querying condition; system replaces the conditional-variable in the query grammar with parameter value corresponding to querying condition, be converted into the query statement that background data base 1 can directly be carried out.When domestic consumer need to gather the multiclass Query Result, will use the grouping variable, usually be applied to the different situation of condition of each inquiry, directly can't obtain desirable Query Result with conventional query statement.The grouping variable is with designated symbols "@" beginning (with "@variable name@" expression), being used for repeatedly, circulation obtains different Query Results, be equivalent to obtain respectively different subquery statements according to the different subitems of grouping variable, each subquery statement is carried out once independently inquiry and is obtained the subquery result, utilize intelligent integrate module 27 to be connected in the same Query Result each subquery result again, generate domestic consumer and hold intelligible Query Result.In actual use, the grouping variable is optional, only have the user of working as the multiclass Query Result need to be simultaneously displayed in the middle of the query results, and the querying condition of these statisticss, computing method are all different, can't use in the situation that single query statement finishes, just can use the grouping variable.
