Detailed Description
In order to make those skilled in the art better understand the technical solutions in this document, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all of the embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step based on the embodiments in this description shall fall within the scope of protection of this document.
The idea of the embodiment of the specification is that a data exploration model is trained based on the incidence relation of the field characteristics of the fields in the target end data table and the source end data table, so that when the fields in the target end data table corresponding to the source end data table are explored, the source fields corresponding to the fields can be directly explored by the trained data exploration model according to the field characteristics of the fields to be explored, exploration in a layer-by-layer tracing mode on the target data table based on the blood relationship is avoided, the time consumption is short, and the efficiency is remarkably improved; the automatic exploration of the target-side data table is realized based on a data exploration model, manual intervention is not needed for analysis, and a large amount of labor can be saved; and moreover, the data table of the target end is probed through the data probing model, so that the probing mode is more objective. Based on this, this specification embodiment provides a data exploration method and device. The following is a detailed description.
First, to facilitate understanding of the methods provided by the embodiments of the present specification, the following will describe a data surface hierarchy of a source data table to a target data table. As shown in fig. 1, the service result table in the service domain is processed on the basis of the source-side data table in the data mart layer, and finally, a service result table of the target side is generated. Wherein, several rounds of processing are carried out on the source data table, and then several intermediate data tables are generated. That is, for the source-end data table in the data mart layer, the target-end service result table is finally obtained through at least one middle-layer data table. By adopting the method provided by the embodiment of the specification, the fields in the source end data table in the data mart layer corresponding to the fields in the service data table can be directly detected without detecting the middle layer data table layer by layer.
A specific application scenario of the method provided in the embodiment of this specification may be, in the field of data supervision, probing a source data table of data to be supervised. Or, the method can also be applied to the field of data compliance, and probe of target-end data is carried out during data compliance audit.
It should be noted that the data exploration method provided in the embodiment of the present specification may be applied to a terminal device with computing capability, such as a computer, a tablet computer, and the like; or, the method can also be applied to a service platform which needs to perform data exploration, such as a data supervision platform.
Fig. 2 is a first flowchart of a data probing method provided in an embodiment of the present disclosure, and as shown in fig. 2, the method at least includes the following steps:
Optionally, in a specific embodiment, the data table may be subjected to type division in advance according to a certain dimension, that is, all data table types corresponding to the data table are determined. For example, in one particular dimension of division, the data table types may include order tables, product tables, user information tables, and the like. Of course, the data table type may also be determined according to other dimensions, which are only exemplary and not limiting to the embodiments of the present specification.
Therefore, in the implementation of step 202, the data table type to which the target data table belongs may be determined from a plurality of data table types obtained by dividing in advance. Specifically, the set classification rule may be a field semantic matching manner.
In the embodiment of the present specification, the data table type to which the target data table belongs is determined, so that the target data table can be probed from the source data table which belongs to the same type as the target data table, that is, the range for performing data probing is reduced, thereby reducing the workload of subsequent probing and further improving the data probing efficiency.
Optionally, in a specific embodiment, a certain field, some fields, or all fields in the target data table may be probed based on actual requirements. For example, in the technical field of data supervision, if a target data table to be supervised includes five fields, namely field 1, field 2, field 3, field 4 and field 5, and currently, field 3 in the target data table needs to be supervised, in this application scenario, a source field corresponding to probe field 3 needs to be supervised.
Specifically, the target field characteristics may be semantic characteristics of a field, content characteristics of content corresponding to the field, statistical characteristics of content corresponding to the field, and the like. The specific content of the above target field features may be determined based on specific fields, which is not limited by the embodiments of the present specification.
And step 206, based on the target field characteristics and the pre-trained data exploration model, exploring the source field corresponding to the target field from the source data table belonging to the same type as the data table to be targeted.
The data exploration model is obtained by training based on the incidence relation between the field characteristics of the target end field and the field characteristics of the corresponding source end field.
Specifically, the above association relationship may be understood as that the field characteristics are equal, or there is some operation relationship, such as summation or multiple relationship. In fact, it can be understood that the data exploration model is mainly generated based on the process of converting the source field into the target field or the conversion condition. For example, in an embodiment, the value of the field corresponding to the source field is divided by a set value to obtain the value of the field corresponding to the destination field, and in this case, the data exploration model is such that the value obtained by multiplying the destination field by a set multiple and the value of the field corresponding to the source field satisfy an equal relationship.
According to the data exploration method provided by the embodiment of the specification, the data exploration model is trained based on the incidence relation of the field characteristics of the fields in the target end data table and the source end data table, so that when the fields in the target end data table are explored in the fields corresponding to the source end data table, the trained data exploration model can be adopted to directly explore the source fields corresponding to the fields according to the field characteristics of the fields to be explored, exploration in a layer-by-layer source tracing mode on the target data table based on the blood-related relation is avoided, the time consumption is short, and the efficiency is remarkably improved; the automatic exploration of the target-side data table is realized based on a data exploration model, manual intervention is not needed for analysis, and a large amount of labor can be saved; and moreover, the data table of the target end is probed through the data probing model, so that the probing mode is more objective.
In order to facilitate understanding of the methods provided by the embodiments of the present disclosure, the following detailed description will discuss specific implementation processes of the above steps.
Optionally, in this embodiment of the present specification, because the source field corresponding to the target field needs to be determined from the source data table belonging to the same type as the target data table, all the source data tables need to be classified in advance, so as to obtain the source data table set corresponding to each data table type. For example, if the data table types include data table type a, data table type B, and data table type C, in a specific implementation, the source data table needs to be divided into a source data table set corresponding to the data table type a, a source data set corresponding to the data table type B, and a source data table set corresponding to the data table type C.
Therefore, before the step 202 is executed, that is, before determining the type of the data table to which the target data to be probed belongs according to the set classification rule, the method provided in the embodiment of the present specification further includes:
and classifying the source data tables according to set classification rules to obtain a source data table set corresponding to each data table type.
In the embodiment of the present specification, the source data table is divided into a plurality of sets according to the data table type corresponding to the source data table in advance, so that when performing data exploration on the target data table, only the source data set having the same data table type as the data table to which the target data table belongs needs to be explored, and therefore, the workload of data exploration can be reduced, the data exploration period can be further shortened, and the data exploration efficiency can be improved.
For example, in a specific embodiment, if the data table type corresponding to the target data table is the data table type B, it is only necessary to perform the probing of the target field in the target data table in the source data table type set corresponding to the data table type B, so that the probing in the source data table sets corresponding to other data table types is omitted.
In the embodiment of the present specification, the type of the data table to which the target data table belongs is determined, and is the same as the classification rule adopted for classifying the source data table. Therefore, in the embodiments of the present specification, a specific implementation process of one of the above is described as an example, and details of another specific implementation process are not described again.
Optionally, in a specific embodiment, the type of the data table to which the target data table to be probed belongs is determined according to a set classification rule, which may specifically be implemented through the following processes:
matching the field names of all fields in the target data table with type keywords corresponding to all data table types; and determining the data table type of the target data table according to the matching result.
Optionally, in a specific embodiment, the type key corresponding to each data table type may be set based on a field generally included in the data table type. For example, for the transaction table, it is usually necessary to include related field information such as an order number, a transaction amount, a transaction time, and a transaction account number, and therefore, a type keyword corresponding to the transaction table may be set based on the related field information, for example, the set type keyword may include an order number, an amount, a time, an account number, a transaction, and the like. Of course, the description is only exemplary and should not be construed as limiting the embodiments of the present disclosure.
In this embodiment of the present specification, the field names of the fields in the target data table are matched with the type keywords corresponding to the types of the data table, where the number of the keywords that are the same as the field names in the target data table or similar to the semantics in the type keywords corresponding to the types of the data table may be matched, and then the data table type with the largest number of the keywords is determined as the data table type to which the target data table belongs.
For ease of understanding, the following description will be given by way of example.
For example, in one embodiment, it is assumed that there are three data table types, denoted as data table type a, data table type B, and data table type C;
the type key words corresponding to the data table type A comprise: keyword 1, keyword 2, and keyword 3;
the type key words corresponding to the data table type B comprise: keywords 11, 12, 13, and 14;
the type key corresponding to the data table type C comprises the following types: keywords 111, 112, 113, and 114;
the field names of the fields contained in the target data table are respectively as follows: field 1, field 2, and field 3;
matching the field 1, the field 2 and the field 3 with type keywords corresponding to the data table type A, the data table type B and the data table type C respectively; if the matching result indicates that the number of fields matched with the data table type A (the field names are the same as the type keywords or similar in semantics) in each field corresponding to the target data table is 1, the number of fields matched with the data table type B in each field corresponding to the target data table is 3, and the number of fields matched with the data table type C in each field corresponding to the target data table is 0. Therefore, according to the matching result, the number of the fields matched with the type key word corresponding to the data table type B in the fields corresponding to the target data table is the largest, that is, the matching degree between the fields corresponding to the target data table and the type key word corresponding to the data table type B is the highest. Therefore, the data table type to which the target data table belongs can be determined to be the data table type B.
Optionally, in a specific embodiment, the data exploration model includes exploration rules corresponding to each field type, where the exploration rules are used to describe matching rules that are satisfied by field features of fields having an association relationship;
correspondingly, in the step 206, the method for searching the source field corresponding to the target field from the source data table belonging to the same type as the target data table based on the target field characteristics and the pre-trained data search model specifically includes the following steps 2062, 2064 and 2066, as shown in fig. 3.
The field type may include a numeric field, a string field, an enumeratable field, or a status field. Correspondingly, the data exploration model includes exploration rules corresponding to numeric fields, exploration rules corresponding to string fields, exploration rules corresponding to enumerable fields, and exploration rules corresponding to state fields.
In order to facilitate understanding of the methods provided by the embodiments of the present specification, the following will exemplarily describe the probing rules corresponding to the above-mentioned field types. Of course, the description is only exemplary for the convenience of understanding, and does not limit the probing rules mentioned in the embodiments of the present specification.
For example, in one embodiment, for a string-type field, the field value corresponding to the field is a string, and therefore, for the field of the type, the set probing rule may be that the field value corresponding to the target field is equal to (or the same as) the field value corresponding to the source field; for a numerical field, such as a transaction amount, a transaction number, etc., a field value corresponding to the field is a specific numerical value, and for the field of the type, unit conversion (the unit conversion may involve a multiple-multiplication-division operation), an addition-subtraction operation, a statistical operation, etc. may be performed on a source field in a process of obtaining a target field from the source field, and therefore, for the field of the type, a set probing rule may be set such that the target field and the source field satisfy a set multiple relation, or a sum or a difference is a set numerical value, etc.; for a field of a type of state, a field value corresponding to the field is generally a state value, and in general, the field value corresponding to the field may be a corresponding state value only when triggered by a certain trigger condition.
For example, the target field is a transaction state, and the transaction state is a success state when the transaction time and the transaction amount meet set conditions; therefore, the set probing rule can enable the transaction time and the transaction amount corresponding to the same transaction state in the target field and the source field to meet the same set conditions.
Of course, the above description is only exemplary to list several possible probing rules, and does not limit the embodiments of the present specification.
Accordingly, in step 2064, the target field characteristic is matched with the field characteristic corresponding to each source field of the same field type in the source data table of the same type, and whether the field characteristics are the same or not may be compared, or whether some operation (such as addition or subtraction) is performed on the field characteristics to determine whether the operation result satisfies a certain condition or not. The specific matching process may be decided based on the field type.
Optionally, in a specific embodiment, in the step 204, determining a target field characteristic corresponding to a target field that needs to be probed in the target data table specifically includes:
determining the field type of the target field; and determining the target field characteristics corresponding to the target field based on the field characteristic determination rule corresponding to the field type.
The field types comprise a numerical value type field, a character string type field, an enumeratable type field or a state type field.
Of course, in the embodiment of the present specification, the field type is only divided according to one dimension, and in a specific implementation, the field type may also be divided according to other dimensions, which is only exemplary and does not limit the embodiment of the present specification. In addition, it should be noted that the embodiments in this specification merely list several possible field types, the listed field types do not represent all field types, the field types may also include others, and no one of the embodiments in this specification is further listed.
Optionally, in a specific embodiment, determining the target field characteristic corresponding to the target field based on the field characteristic determination rule corresponding to the field type may include any one of the following determination manners:
determining each field value corresponding to the target field as a target field characteristic;
determining the trigger condition corresponding to each field value corresponding to the target field as the target field characteristic;
and taking the appointed operation result of each field value corresponding to the target field as the target field characteristic.
For example, in one embodiment, for a field of a string type, a field value corresponding to the field may be determined as a field characteristic corresponding to the field; for a state type field, determining a trigger condition corresponding to a field value corresponding to the field as a field characteristic corresponding to the field; for a numerical field, a specified operation result (such as a summation operation, a multiple operation, etc.) of a field value corresponding to the field may be determined as a field characteristic corresponding to the field; for example, for a field of an enumerable type, the field value corresponding to the field may be determined as the field characteristic corresponding to the field.
Of course, specific determination manners of field characteristics corresponding to each type of field are only exemplified here, and do not constitute a limitation on the embodiments of the present specification.
In addition, in this embodiment of the present specification, the trigger condition corresponding to the field value may be a field value corresponding to one or more other fields in the target data table.
Optionally, in a specific implementation, the method provided in the embodiments of the present specification may be applied to the technical field of supervision or the technical field of compliance.
For example, if the method provided in the embodiments of the present specification is applied to the technical field of compliance, the business result table may be selected from data fields of users, merchants, institutions, finance, products, and the like, the financial behavior may be derived from change of subject information, fund information, transaction information, and the like, and the environment where the financial behavior is located may specifically be a source, a geographic location, or a behavior context, and the like. Of course, the description is only exemplary and should not be construed as limiting the embodiments of the present disclosure.
The data exploration method provided by the embodiment of the specification at least has the following beneficial effects: the data exploration model is trained on the basis of the incidence relation of the field characteristics of the fields in the target end data table and the source end data table, so that when the fields in the target end data table are explored in the fields corresponding to the source end data table, the source fields corresponding to the fields can be directly explored by the trained data exploration model according to the field characteristics of the fields to be explored, exploration of the target data table in a layer-by-layer tracing mode based on the blood-related relation is avoided, time consumption is short, and efficiency is remarkably improved; the automatic exploration of the target-side data table is realized based on a data exploration model, manual intervention is not needed for analysis, and a large amount of labor can be saved; moreover, the data table of the target end is probed through a data probing model, so that the probing mode is more objective; when data exploration is carried out, the data table type of the target data table is determined, so that the target data table can be explored from the source data table which belongs to the same type as the target data table, namely, the data exploration range is narrowed, the workload of subsequent exploration can be reduced, and the data exploration efficiency is improved.
On the basis of the same idea, corresponding to the method provided by the embodiment of the present specification, the embodiment of the present specification further provides a data exploration apparatus for executing the method provided by the embodiment of the present specification.

The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
