Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a data source invoking method, as shown in fig. 1, the method includes:
101. based on the standardized interface, input parameters are received.
Wherein the standardized interfaces can receive different data sources of the same type. For example, the Beijing market identification number data source, Shanghai market identification number data source, national male identification number data source and the like are different data sources of the same type.
102. And calling a target data source corresponding to the input parameter.
For the embodiment of the present invention, the corresponding target data source may be called through the type of the input parameter, or the corresponding target data source may be called through the key information carried in the input parameter, which is not limited in the embodiment of the present invention.
For calling the corresponding target data source through the key information carried in the input parameters, the following algorithm can be adopted for implementation:
suppose that the input parameters carry M pieces of key information, and the weight of each piece of key information is Wi(1≤i≤M)。WiThe key information can be scored by a user according to different types of the key information or determined according to an analytic hierarchy process. The matching degree of any data source and the ith key information is assumed to be UiThen U isiIs 0 or 1:
calculating corresponding of each data source
Find out
The data source corresponding to J is the target data source.
According to the method, the target data source with the maximum matching degree with the key information can be selected, and the target data source can be matched with the data source expected by the user to the maximum extent.
103. And calculating the input parameters according to the target data source to obtain an output result.
For example, when the input parameters are the name and the identification number, after the identification number data source of the province where the input parameter is located is called according to the identification number, the name information corresponding to the identification number is searched in the identification number data source of the province, so that whether the name in the input parameters is correct or not is judged, and a corresponding output result is obtained.
Compared with the prior art, different data sources can be called through a unified standardized data interface, and therefore the complexity of calling the data sources can be reduced.
Another embodiment of the present invention provides a data source calling method, as shown in fig. 2A, the method includes:
201. and establishing a corresponding relation between each piece of key information and each data source.
Wherein, different key information respectively corresponds to different data sources. For example, for the ID card number data source, when the first two digits of the key information are '11', the key information corresponds to the ID card number data source in Beijing City; when the first two digits of the key information are '61', the key information corresponds to the ID number data source of Shaanxi province.
202. And storing the corresponding relation between each piece of key information and each data source.
203. Based on the standardized interface, input parameters are received.
Wherein the standardized interfaces can receive different data sources of the same type. For example, the Beijing market identification number data source, Shanghai market identification number data source, national male identification number data source and the like are different data sources of the same type.
204. And extracting key information in the input parameters.
The key information is used for determining a data source corresponding to the key information. For example, for the identification number, the key information can be the first 2 bits of the identification number, so that the corresponding provincial identification number data source can be called; the key information can also be the 7 th to 10 th digits of the ID number, so that the province number data source of the birth year of the ID number can be called.
205. And calling the corresponding target data source according to the key information in the input parameters.
For the embodiment of the invention, when the target data source is not called, the standby data source is called. In the embodiment of the invention, the standby data source is called when the calling of the data source fails, so that the coverage range of the data source can be effectively improved, and the information of each data source is fully utilized.
For the embodiment of the invention, when the state of the called target data source is abnormal, the standby data source is called. In the embodiment of the invention, the standby data source is called when the target data source is in an abnormal state, so that the system stability can be effectively improved.
And calling the standby data source when the target data source is in an abnormal state, wherein the standby data source and the target data source have certain deviation and are not completely consistent. In order to ensure that the deviation between the finally called standby data source and the target data source is small, the following algorithm may be adopted to select a more suitable standby data source from all other optional standby data sources except the target data source for calling:
suppose there are M pieces of key information in the input parameters, and the weight of each piece of key information is Wi (i is more than or equal to 1 and less than or equal to M). Wi can be scored by the user according to different types of key information or determined according to an analytic hierarchy process. Calling corresponding relations between the key information and the optional standby data sources; according to the corresponding relation, the matching degree Ui of any optional standby data source and the ith key information is calculated by using the following function:
in the formula, xi,0The value of the ith key information is obtained; x is the number ofi,minThe value lower limit of the preset key information which belongs to the same type of information as the ith key information is set; x is the number ofi,maxThe value upper limit of the preset key information which belongs to the same type of information as the ith key information is set; x is the number ofiThe value of the key information which belongs to the same type of information as the ith key information in the key information corresponding to the optional standby data source currently being calculated is obtained.
In the function, for convenience of calculation, each piece of key information in the stored correspondence between each piece of key information and each data source is assigned in advance to obtain a value of each piece of key information in the correspondence. For example, all the key information in the corresponding relationship is classified according to the meanings expressed by the key information, and the meanings are classified into one class; assigning values to each key information in the same type according to an assignment rule, wherein the assignment rule can be that a basic meaning corresponding to the type is set according to the meaning of each key information in the same type; and assigning values to each piece of key information according to the similarity between the meaning of each piece of key information under the type and the basic meaning. The following examples illustrate: there are five key information "rock", "musical instrument", "food", "dress" in the corresponding relation, wherein, have the relation among the meanings "rock", "musical instrument", can classify the three key information into a kind, and presume a basic meaning for this kind is "music"; the meaning of the three key information in the type is different from the similarity between the basic meanings, wherein the similarity of the rock is greater than that of the instrument, so when the rock is assigned with 80, the instrument can be assigned with 50, and the specific assignment rule is what can be self-defined and is within the protection scope of the application.
Calculating for each alternative backup data source
Find out
The optional standby data source corresponding to J is the standby data source for final call.
E.g. as shown in FIG. 2B, xi,0＝5，xi,min＝1，xi,maxWhen x is 9, if xiWhen the value is 6, then Ui＝0.853553。
According to the method, the standby data source which is matched with the key information can be selected, and the standby data source which is matched with the data source expected by the user can be called as far as possible under the condition that the target data source cannot be obtained, so that the condition that the user cannot obtain any data source as a reference is avoided.
206. And calculating the input parameters according to the target data source to obtain an output result.
For example, when the input parameters are the name and the identification number, after the identification number data source of the province where the input parameter is located is called according to the identification number, the name information corresponding to the identification number is searched in the identification number data source of the province, so that whether the name in the input parameters is correct or not is judged, and a corresponding output result is obtained.
