Embodiment
Below in conjunction with accompanying drawing the present invention is described, but does not limit the present invention.
The principle of the invention is shown in Fig. 1 a, Fig. 1 b and Fig. 1 c, and wherein n is a natural number.
As shown in Figure 1a, the first step is to set up parameterized template.Promptly keyword is classified by elder generation, establishes to be divided into classification 1, classification 2 ... classification n has only bottom classification ability modeling plate.Set up parameterized template according to classification then, parameterized template specifying information and entity relationship are entered in the database, parameterized template is corresponding in database to generate a dynamic table: 1 the corresponding dynamic table 1 that generates of parameter digital-to-analogue plate of promptly classifying, the corresponding dynamic table 2 that generates of the parameterized template of classification 2 ... the corresponding dynamic table n that generates of the parameterized template of classification n.
Shown in Fig. 1 b, second step was the typing product parameters.Be provided with product 1, product 2 ... product n, find the corresponding parameters template by this product place classification earlier, promptly find corresponding parameters template 1, find corresponding parameters template 2 by the classification of product 2 places by the classification of product 1 place ... find corresponding parameters template n by the classification of product n place.By this parameterized template product parameters information is entered in the corresponding dynamic table then, promptly the parameter of product 1 is entered in the dynamic table 1 by parameterized template 1, and the parameter of product 2 is entered in the dynamic table 2 ... the parameter of product n is entered among the dynamic table n.
Shown in Fig. 1 c, the 3rd step was to use this search engine.At first find the relevant parameters template according to the keyword that will inquire about, promptly find relevant parameters template 1, parameterized template 2 according to this keyword ... or parameterized template n, by this relevant parameters template querying condition being spliced into the relational database query statement again inquires about in the corresponding dynamic table, even find 1 inquiry in dynamic table 1 of parameterized template, if find 2 inquiries in dynamic table 2 of parameterized template ... if find parameterized template n then in dynamic table n, to inquire about.At last the result who inquires about in the dynamic table is returned.
By this principle, can be in relational database definition of data relationship entity figure, the i.e. storage means of dynamic table.This sterogram as shown in Figure 2, PK represents major key, FK1 represents first external key, FK2 represents second external key, FK3 represents the 3rd external key.Major key under the keyword classification table is the keyword classification major key.Major key under the parameterized template table is the parameterized template major key, and first external key under the parameterized template table is the keyword classification major key.Major key under parameter item unit's sorted table is parameter item unit's classification major key.Major key under the parameter item table is the parameter item major key, and first external key under the parameter item table is parameter item unit's classification major key.Major key under parameter item unit's table is parameter item unit's major key, and first external key under parameter item unit's table is parameter item unit's classification major key.Major key under the parametric classification table is the parametric classification major key.Major key under the parametric classification-parameter item table (corresponding relation between expression parametric classification and the parameter item) is parametric classification-parameter item major key, first external key under parametric classification-parameter item table is the parametric classification major key, and second external key under parametric classification and the parameter item mapping table is the parameter item major key.Major key under template-parametric classification-parameter item table (corresponding relation between expression parameterized template, parametric classification and the parameter item) is template-parametric classification-parameter item major key, first external key under template-parametric classification-parameter item table is the parameterized template major key, second external key under template-parametric classification-parameter item table is the parametric classification major key, and the 3rd external key under template-parametric classification-parameter item table is the parameter item major key.
Be the content that passenger vehicle illustrates dynamic table below with the keyword.
Being categorized as of its keyword classification table " automobile＞car load＞passenger vehicle ", the content of parameterized template table is the passenger vehicle parameterized template, the content of parameter item unit's sorted table is length and weight, the parameter item table record be (for example vehicle, length overall, the beam overalls, always high) such as data types, length of concrete each row of dynamic table, the content of parameter item unit's table is kilometer, millimeter and kilogram, and the content of parametric classification table is important technological parameters, engine parameter and chassis configuration.
The content of parametric classification-parameter item table is: important technological parameters comprises vehicle, length overall, beam overall, height overall; Engine parameter comprises engine model, engine mode and engine emission standard; The chassis configuration comprises chassis producer, chassietype, variator.
The content of template-parametric classification-parameter item table is: the passenger vehicle parameterized template comprises important technological parameters, engine parameter and chassis configuration; Important technological parameters comprises vehicle, length overall, beam overall, height overall; Engine parameter comprises engine model, engine mode and engine emission standard; The chassis configuration comprises chassis producer, chassietype, variator.
The consistency operation synoptic diagram of establishment parameterized template as shown in Figure 3 and Figure 4.Will create a passenger vehicle parameterized template now such as us, system's consistency operation is as follows:
As shown in Figure 3, on classification tree, select the passenger vehicle classification, click the establishment parametric classification of configuration template the inside, can import concrete information such as parametric classification title on the right.Set up parametric classifications such as important technological parameters among Fig. 3, point can be kept at the data of this parametric classification in the parametric classification table when preserving.
As shown in Figure 4, can in parametric classification, add concrete parameter item.Be example with the important technological parameters in the parametric classification among the figure, can the typing vehicle etc. parameter item.
Point adds a record and dynamically generates a table (dynamic table) according to parametric classification and the concrete information of parameter item in database in parameterized template when preserving this template, this table name adds certain rule name by systematic name, be used for being stored in the concrete attribute information of product that this parameterized template adds, such as: seating capacity, information such as length overall.
Corresponding each undermost classification just can define a corresponding parameters template according to this storage rule.Because different parameterized template parameters is different, when corresponding product parameters is with search so typing is for convenience classified a self-defined control has just been done in the input of querying condition under the different parameterized templates.During the typing product parameters, be to transmit product parameters between the dynamic table of corresponding parameters template and correspondence by this control.Find classification by keyword during search, find the major key of keyword classification table according to classification, between relevant parameters template and the corresponding dynamic table, this control dynamically shows the specifying information of the parameterized template under this classification according to the major key that imports into, import various querying conditions by this control then, and querying condition is spliced into the relational database query statement by this control, in dynamic table, inquire about.
This control can be used a variety of language compilation, is that example illustrates below with the C# language.Function and function parameter thereof are as follows in the control, and wherein function English name and function parameter are in the bracket of function Chinese back.
The function of private type:
Newly-increased classification display parameter information (private void Show (string strClassID));
According to classification, production code member display parameter information (private void Show (string strClassID, stringstrProduct ID));
Direct search parameter item display parameter information does not need classification, production code member (private void Show2 (stringstrClassID, string strParameterClassID));
Show search engine (private void ShowSearchEngine (string strClassID, stringstrEngineID));
Display parameter item (private void ShowItem (string strParameterItemiD));
According to a concrete reference record, generate the control (private void ShowParameter (DataRowdr, int type, string strClassName)) on the page;
Generate corresponding control (private void ShowParameterClass (stringstrParameterClassName, DataRow[] drParameterItem) according to parametric classification);
Show head (private void ShowHead ());
Show afterbody (private void ShowBottom ());
Create form (private void CreatTable ());
Tape unit classification adds record (private void InsertRow (string strParameterItemCode, stringstrControlName, string strInputType, string strParameterClass, stringstrParameterItemName, string strDataType, string strParameterClassName, stringstrParameterItemID));
Increase record (private void InsertRow (the string strParameterItemCode of tape unit classification, string strControlName, string strInputType, string strParameterClass, stringstrParameterItemName, string strDataType, string strParameterClassName, stringstrUniTypeID, string strParameterItemID));
Binding unit item (private void BindOption (DropDownList ddl, stringstrUnitTypeID, string strUnitId));
The function of protection type:
Set up child control (protected override void CreateChildControls ());
The function of publicly-owned type:
Show all information (public void ShowInfo ());
Remove control (public void Clear ());
Open modal window (public void OpenModelWin (System.Web.UI.Page jsPage, WebControltouchControl, string ClientEventName, string url, string urlParameter, int width, intheigh, string strArgs, Control GetValueControl));
Each function calls is closed and is in the control:
As shown in Figure 5, ShowInfo function call CreateChildControls function.CreateChildControls function call Show, Show2, ShowItem, four functions of CreateTable, ShowSearchEngine.Two functions of Show, Show2 all call ShowHead, ShowParameter, four functions of ShowParameterClass, ShowBottom.Three functions of ShowItem function call ShowHead, ShowParameter and ShowBottom.ShowSearchEngine function call ShowParameterClass function.Three functions of ShowParameter function call OpenModelWin, InsertRow and BindOption.
The principle of work of this control is:
Code in the control is judged the display mode (directly input, drop-down selection, individual event selection, multiselect) of child control by the parameter of importing into, then by the Controls collection object, automatically create relevant control, pattern and the layout of controlling each child control by Add method and the hand-written HTML SGML of Controls, (remove control, create form for public duplicated code repeatedly, binding unit item etc.) then carried out the function encapsulation, all called by this control biography ginseng on user management backstage and foreground searched page parameter search function.
At first, show that all information functions (ShowInfo) have guided the beginning of whole control, this function has encapsulated the function of protection and has set up child control (CreateChildControls).In the CreateChildControls function, create form (TABLE) by creating table function (CreateTable); Simultaneously, the CreateChildControls function is judged the status information (Type) of the reception and registration of invoking page, this function is selected the needs content displayed according to status information then: display parameter information (two Show function and Show2 that name is identical, parameter is different), display parameter item (ShowItem) or demonstration search engine (ShowSearchEngine); Last Show, Show2, ShowItem and ShowSearchEngine function have begun the orderly assembly unit of carrying out the control detail content:
1) during display parameter information, need to show head (ShowHead), control (ShowParameter) according on the concrete reference record generation page generates corresponding control (ShowParameterClass) according to parametric classification, shows afterbody (ShowBottom);
2) the display parameter item is just comparatively simpler, and the page of application only need show head, and the control according on the concrete reference record generation page shows afterbody;
When 3) showing search engine, content displayed is more special, and what need is to generate corresponding control according to parametric classification;
Just enter the concrete reference record of the most complicated most crucial basis then and generated control (ShowParameter) process on the page:
1, the parameter imported into of this function is record row (dr), control type (type), classification (strClassName), judges the display mode of child control as parameter by the row strInputType of dr:
1) when being D, the strInputType parameter then is direct input display mode (text box).
2) when being A, the strInputType parameter then is drop-down selection display mode (drop-down list).
3) when the strInputType parameter is C then for singly selecting display mode.
4) when being B, the strInputType parameter then is the multiselect display mode.
The value of other row of dr all is to obtain from database by storing process, defines by the main attribute of these row to whole control, finishes before Show function call ShowParameter function and be listed as the process of obtaining data.
2, under different display modes, pass through the judgement of same flow process again:
1) judge by the parametric t ype that imports into: if type is not 2, then the font Show Styles is a black, if type is 2, and then special processing font style.
2) through after the step 1), call the Controls.add method again, on the interface, add child control according to display mode.These child controls comprise text box (single file or multirow textbox), drop-down selective listing (DropDownList) or options (individual event or multinomial lable).
All call public function during the specific implementation of step 2 again, promptly (InsertRow), binding unit item (BindOption) are not write down in the increase that adds record or tape unit classification of tape unit classification, and step 2 provides heavily loaded public function to open modal window (OpenModelWin) simultaneously.
Characteristic according to this self-defined control, when the represented product of typing keyword classification, can deposit the product corresponding parameters in the corresponding dynamic table, when search on the foreground according to classifying and initial conditions different are spliced into different query statements and come product is inquired about.
