Fig. 3 shows the concrete schematic flow diagram of data query method according to embodiments of the present invention.
As shown in figure 3, data query method according to embodiments of the present invention specifically includes：
Step 302, carries out interaction relation (default inquiry relation) setting.Set in statement form and center each data field
Between interaction relation, interaction relation is saved in data section model as object, and interaction relation comprises main data area to from data
Certain field in the sensing in area, main data area to from data field certain field sensing, by the word of two data fields
Section relation sets up interaction relation.Interaction relation if there are multiple fields, then between these relations can by and and/or patrol
Collect pre- operator to connect.If also the 3rd data field needs to arrange interaction relation, then can appoint in the first two data field
Meaning selects a data field as main data area the 3rd conduct from data field, carries out the setting of interaction relation.Multiple data fields
Just constitute the chain of a linkage rule；
Step 304, after user is provided with linkage rule in reporting tableau format model, (i.e. preset query condition can be with
Data mode is present in data field, and such as data field A is directed to the querying condition of data field B, can be in the form of a data
It is present in the A of data field), then user is choosing when linkage as main data area in a certain data field it is necessary to parsing linkage is advised
Then and produce linkage condition.First have to read the object of the setting of linkage rule from main data area during parsing linkage rule,
Find out from this rule objects again from data field (target data area), pass through major key from data field object or other are uniquely marked
Note or pointer obtain, and finally select corresponding field in linkage rule from a data of the selected main data area of user
Concrete data is spliced into the condition part in required query statement from data field again；
Step 306, the linkage being spliced in step 304 condition is assembled into querying condition object, as parameter transmission
To back-end data area executor, data field executor is responsible for for all conditions being assembled into complete query statement and looks into from data base
Ask data；
Step 308, Query Result is assembled into the data set of data field, and the data field being supplied in form represents；
Step 310, after completing the linkage of two data intervals, if that mentions in above-mentioned steps goes back from data field
If linkage rule, then it is regular to continue this linkage of parsing, and repeatedly step 304 to step 308.The process reference of parsing
Step 304, simply this operation of a data selected by user is completed by system default, and acquiescence selects the first data as linkage
Condition.Certainly acquiescence linkage rule can designate whether to come into force with statement form setting, if come into force, the step for carry out such as
So linkage process that really do not come into force leaves it at that；
Step 312, after all data field execution having direct or indirect linkage rule relation with main data area are completed,
All data sets are flushed on interface by report model, are finally presented to user.The algorithm of report form showing is according to form product
Exhibiting method is consistent.
Fig. 4 shows the schematic diagram of multistage linking according to embodiments of the present invention.
As shown in figure 4, data field A data area B is Liang Ge cohersive and integrated data area, data field C is a detailed data area, number
It is a chart data area according to area D.Based on this linkage rule relation, briefly to introduce down the majority according to the embodiment of the present application
According to area's linkage.
Four data fields of upper in figure are realized multistage linking in same form, needs several steps as follows：
Setting linkage rule, first using cohersive and integrated data area A as main data area, then the linkage of setting on A data field
Rule comprises tri- regions of A, B, D.The rule (i.e. main data area A is directed to the preset query condition from data field B) of A to B is permissible
The field 1 being set in A is equal with the field 1 in B, and the value of the field 2 in B is greater than 100, and this is exactly the connection of A to B
Dynamic rule.Field 1 in the regular A of linkage of A to D is equal with the field 1 in D and A in field 3 and D in field 3 phase
Deng, this be A to D linkage rule.Next the linkage rule of setting B to C, B to C only need to be arranged in field 1 and C in B
Field 1 is equal.
When user-selected number is according to certain data in area A, system can read rule (i.e. from the rule setting of data field A
The preset query condition that data field A is directed to its next stage data field is stored in the A of data field), then rule is carried out at packet
Reason, is related as one group with data field B, related to data field D for another group, then analyze in order.Thus draw B respectively
With the querying condition of D, the condition of B is the first character segment value that first character section in B is equal to the selected data in A of user, B
Second field be more than 100.The condition of D is the first character section of the first character section in D and the selected data in A of user
Equal, the 3rd field of the 3rd field data selected in A with user in D is equal.
After all linkage conditions of above-mentioned steps are all parsed, start according to respective condition pass through region executor from
Execution inquiry peek in data base.During this or make a judgement, judge whether to support silent after the completion of this site polling
Recognize linkage, if otherwise terminate to link in this region, if it is need to obtain the linkage rule setting in this region, judge this region
Whether there is linkage rule, so continue second step if there is linkage rule.Obviously in this example, D region has not had
Linkage rule setting, then D region also just finishes, but but there is linkage setting in B region, then and B region will repeat second
Individual step, when linkage is to C region, also without linkage setting, then C region also finishes in C region.
After above-mentioned linkage inquiry and acquiescence linkage terminate, then whole linkage process is also just only remaining to be presented, and represents
Thing is consistent with report model, so not just being repeated here.
After user finishes once linkage, can also continue to link.It is main data area that such as user selects B region now,
Therefrom have selected a data, then it can be seen that there is the only C of interaction relation with B, at this moment only need to C according to second step
The data in region out and represents from data base querying, and linkage also just finishes.
Technical scheme is described in detail above in association with accompanying drawing it is contemplated that in correlation technique, multistage linking cannot
Realize multistage acquiescence linkage it is impossible to realize linkage branch, a form corresponds to a data field, links from number from main data area
