101. acquiring a query request containing business mode data, wherein the business mode data at least comprises map structure information description and detail information description.
Specifically, a service mode is selected through a click command and/or a voice command on a map information query interface, and a query request containing service mode data is triggered according to a selection result. The user carries out triggering query request operation meeting the requirements on a map information query interface of a map information query system through a specific operation instruction, the query request operation comprises service mode data preset and defined by the system interface, and in order to meet the multi-aspect requirements of the user on query data, the service mode data at least comprises map structure information description and detailed information description. The graph structure information description can be composed of one or more of nodes, node attributes, relationships between the nodes and relationship attributes, and the detailed information description can be composed of one or more of the nodes, the node attributes, the relationships and the relationship attributes. It should be noted that the map structure information description and the detail information description may be set differently according to actual situations, and may include any possible service mode design data in the prior art, and the embodiment of the present invention is not particularly limited thereto.
In other cases, according to the needs of the user, the service mode data may further include other data besides the two service mode data, such as deepened processing data for comparison, screening and optimization based on the detail information description, and the user may freely select different service mode data query options of the data to be queried when querying, for example, the user may query the graph structure information data retrieved from the system graph database by selecting the service mode query option only including the graph structure information description, or query the detail information data retrieved from the system relational database by selecting the service mode query option only including the detail information description, or query the user may query the retrieved graph structure information data and the detail information data by selecting the service mode query option both including the graph structure information description and the detail information description, and various query requirements of the user are met.
Illustratively, assuming that a user, as a business person, wants to query the physical store clerk whether to charge a premium, a circular graph structure is designed: clerk A places an order for account B, account B transfers to account C, and account C belongs to clerk A. Fig. 3 is an example of a search input interface (especially, the above-mentioned case can be expressed), and as shown in fig. 3, a service person can input in a map structure information description box:
the method comprises the steps of establishing a node, a salesman A, establishing a list, establishing a node, an account B, establishing a transfer, establishing a node, an account C, establishing a binding relationship, establishing a node, a salesman A and the like. Here, the dashed line "-" indicates a connection; describing element types before colons, namely nodes or relations, and describing specific node types or relation types after colons; A. b, C are reference numbers for elements, like reference numbers referring to like elements.
For business personnel with certain technical background, the description grammar of the map structure information can be completely consistent with the retrieval language supported by the map data; for example, when using Neo4j graph databases, the graph structure can be described using: (clerk a) - [ billing ] - (account) - [ transfer ] - (account) - [ bind ] - (clerk a), where the representation nodes in () represent relationships.
The business personnel can be prompted about the existing node, relationship, attribute name of the system through a list or an input association mode.
The detail information description defines detail data which the business person wants to further acquire, such as the fact that the business person wants to see all the transfer record details given by the customer to the store clerk. The business person may enter the relationship "transfer" in the detailed information description box. Similarly, the service person may also input the node "account B" in the detail information description box, in order to know the detail information of the customer account, such as registration time, member level, and the like, which are not included in the map.
In addition, the traffic pattern may be described in json or html format, for example, the json message of the traffic pattern in the example is as follows:
102. and analyzing the map structure information description in the service mode data by utilizing predefined analysis logic to generate a first retrieval code corresponding to the map structure information description.
Specifically, predefined parsing logic is packaged by adopting a retrieval code template, the retrieval code template comprises codes conforming to the grammar of a corresponding graph database query language, and graph spectrum structure information description is injected into the retrieval code template to generate a first retrieval code with comprehensible graph data.
Illustratively, assuming the system takes neo4j graph data, the retrieval code template may be:
match p＝()-[]-()-[]-()
return p
wherein, the () injects node type, [ ] injects relation type, () and [ ] quantity according to the actual node and relation quantity automatically, match, return are the key words of neo4j database inquiry language. After the atlas structure description information sent by the user interaction module is injected into the template, the following first retrieval code of the atlas database can be obtained:
match p ═ (a: clerk) - [ billing ] - (B: account) - [ transfer ] - (C: account) - [ binding ] - (a)
return p
If the description grammar of the map structure information is completely consistent with the retrieval language supported by the map data, the related processing is not needed after the description of the map structure information is analyzed.
103. And calling a map structure information data query result corresponding to the first retrieval code.
Specifically, the graph database executes the first retrieval code to obtain a corresponding graph structure information data query result.
Illustratively, the information query result contains instance data conforming to the business model, and may be composed of fragment data such as several "(nodes) - [ relationships ] - (nodes)", for example, a json format message of a transfer fragment is:
wherein start represents the start node of the segment, relationship represents the relationship, and end represents the end node of the segment; identity is the only mark of the node and the relation, and start and end in relation explain the direction of the relation; properties represents a node or a relationship property; type indicates a node or relationship type.
104. And analyzing data instance information required by detail information description in the service mode data according to the map structure information data query result, and generating a second retrieval code corresponding to the detail information description according to the detail information description and the data instance information.
Specifically, according to the map structure information data query result, data instance information required by detail information description in the business mode data is analyzed, and a second retrieval code is generated according to a corresponding relational data table structure and the data instance information described by the detail information.
Illustratively, the first step, parsing the data instance information: and when the detailed information in the description of the analysis map structure information is 'transfer', analyzing data instance information corresponding to the 'transfer' type from the map information query result. For example, in the transfer segment data in the above 103 step example, the data instance information refers to account numbers of two accounts corresponding to the transfer relationship, that is, 123456 and 654321.
And secondly, generating a retrieval code supported by the relational data: and the system generates a second retrieval code according to the corresponding relational data table structure and the data instance information described by the detail information. For example, if the table corresponding to the transfer is data, the transfer _ table, the transfer account field is pay _ access _ id, and the payee account is rec _ access _ id, the generated query sql statement is:
Select*from data.transfer_table
Where pay_acct_id＝654321and rec_acct_id＝123456
105. and calling a detail information description data query result corresponding to the second retrieval code.
Specifically, the relational database executes the second retrieval code to obtain the corresponding detailed information description data query result.
Illustratively, the tabular form example of the detailed information description data query results relating to transfers is as follows:
in summary, in the graph information retrieval method provided in the embodiment of the present invention, the service mode data at least including the graph structure information description and the detail information description in the user query request is analyzed to generate the first retrieval code corresponding to the graph structure information description and the second retrieval code corresponding to the detail information description, and the graph structure information description data and the detail information description data corresponding to the first retrieval code and the second retrieval code are called through the first retrieval code and the second retrieval code, so that the comprehensive query of the graph structure information description data and the detail information description data is realized, the graph information is automatically improved and supplemented through the optimization of the graph information retrieval process, and the service understandability and the information saturation of the retrieval result are improved.

Example 3
Fig. 6 is a schematic view of a specific service flow of the map information retrieval method provided in embodiment 3 of the present invention, and as shown in fig. 6, a specific service operation flow of the map information retrieval method provided in the embodiment of the present invention includes:
1. the service personnel designs the service mode (data) to be inquired at the user interaction module, and the service mode at least comprises the map structure information description and the detailed information description.
Illustratively, assuming that business personnel want to query physical store clerks whether to charge a premium, a circular graph structure is designed: clerk A places an order for account B, account B transfers to account C, and account C belongs to clerk A. Referring again to FIG. 3, the business person may enter in the atlas structure information description box:
the method comprises the steps of establishing a node, a salesman A, establishing a list, establishing a node, an account B, establishing a transfer, establishing a node, an account C, establishing a binding relationship, establishing a node, a salesman A and the like. Here, the dashed line "-" indicates a connection; describing element types before colons, namely nodes or relations, and describing specific node types or relation types after colons; A. b, C are reference numbers for elements, like reference numbers referring to like elements.
For business personnel with certain technical background, the description grammar of the map structure information can be completely consistent with the retrieval language supported by the map data; for example, when using Neo4j graph databases, the graph structure can be described using: (clerk a) - [ billing ] - (account) - [ transfer ] - (account) - [ bind ] - (clerk a), where the representation nodes in () represent relationships.
The business personnel can be prompted about the existing node, relationship, attribute name of the system through a list or an input association mode.
The detail information description defines detail data which the business person wants to further acquire, such as the fact that the business person wants to see all the transfer record details given by the customer to the store clerk. The business person may enter the relationship "transfer" in the detailed information description box. Similarly, the service person may also input the node "account B" in the detail information description box, in order to know the detail information of the customer account, such as registration time, member level, and the like, which are not included in the map.
2. And the user interaction module sends the service mode data to the analysis module.
The traffic pattern may be described in json or html format, such as the json message for the traffic pattern in the example as follows:
3. the analysis module receives the service mode from the user interaction module, and the analysis module analyzes the graph structure information description of the service mode into a graph database retrieval code (namely, a first retrieval code) which can be understood by graph data.
And after receiving the service mode data, the analysis module adopts predefined analysis logic to describe and analyze the map structure information into a retrieval code which can be executed by a map database.
The predefined parsing logic may be encapsulated with a search code template that contains codes that conform to the syntax of a corresponding graph database query language, and the graph data comprehensible search codes may be generated by injecting the graph structure information description into the search code template.
Assuming that the system uses neo4j graph data, the retrieval code template may be:
match p＝()-[]-()-[]-()
return p
wherein, the () injects node type, [ ] injects relation type, () and [ ] quantity according to the actual node and relation quantity automatically, match, return are the key words of neo4j database inquiry language. After the atlas structure description information sent by the user interaction module is injected into the template, the following first retrieval code of the atlas database can be obtained:
match p ═ (a: clerk) - [ billing ] - (B: account) - [ transfer ] - (C: account) - [ binding ] - (a)
return p
If the description grammar of the map structure information is completely consistent with the retrieval language supported by the map data, the related processing is not needed after the description of the map structure information is analyzed;
4. the analysis module calls a query interface of the graph database to send a first retrieval code.
5. The graph database executes the first retrieval code to obtain a graph information (i.e., graph structure information) query result.
The information query result contains example data conforming to the business mode, and can be composed of a plurality of segment data such as (nodes) - [ relations ] - (nodes) ", for example, a json format message of a transfer segment is:
wherein start represents the start node of the segment, relationship represents the relationship, and end represents the end node of the segment; identity is the only mark of the node and the relation, and start and end in relation explain the direction of the relation; properties represents a node or a relationship property; type indicates a node or relationship type.
6. The graph database sends a graph information query result to the analysis module.
7. The analysis module receives a map information query result returned by the map data, and analyzes data instance information required for further querying detail information from the map information query result according to the detail information description; and the analysis module generates a second retrieval code supported by the relational database based on the detailed information description and the data embodiment information, and calls a second retrieval code of a query interface of the relational data.
Specifically, 7-1, parsing data instance information: and (4) analyzing the detailed information in the step (2) as 'transfer', and analyzing data instance information corresponding to the 'transfer' type from the map structure information query result. For example, in the clip data in step 5, the data instance information refers to account numbers of two accounts corresponding to the transfer relationship, namely 123456 and 654321.
7-2, generating a search code supported by the relational data: and the system generates a second retrieval code according to the corresponding relational data table structure and the data instance information described by the detail information. For example, if the table corresponding to the transfer is data, the transfer _ table, the transfer account field is pay _ access _ id, and the payee account is rec _ access _ id, the generated query sql statement is:
