[0042] To make the objectives, technical solutions and advantages of the application clearer, the following will describe the technical solutions of the application in detail with reference to the embodiments of the application and the corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the application, but not all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the application.

[0043] The following will describe the technical solutions provided by the embodiments of the application in detail with reference to the accompanying drawings.

[0044] There are many mature platforms for report management on the market, but there are relatively few platforms for mutual fusion and model creation of various reports to realize multi-dimensional perspective analysis, especially a simple configuration based on historical multi-version reports existing in the specific enterprise informatization construction process to complete the integration of data, model and presentation of the data circulation platform is rare on the market, which is a relatively blank field.

[0045] The existing report platform can realize data aggregation, analysis and report for a specific business. However, in the process of enterprise informatization construction development, different versions of report products will be inevitably introduced. At this time, it is difficult to integrate and analyze the data of different versions of reports in different business fields, such as industry and finance integration.

[0046] The analysis reasons are as follows. Firstly, such demand is a relatively small demand, mainly used in enterprises with wide business scope and multiple business types, and similar enterprises will inevitably introduce different versions of reports in the process of informatization construction. The mainstream report manufacturers invest less in the compatibility of other versions of reports. Secondly, the storage format and storage relationship of each report platform are different, which need to be uniformly managed. After all the reports are integrated, they cannot be recognized by anyone, and the report data of different report platforms need to be parsed and formed into unified recognized index data according to the standard. Thirdly, the enterprise data has certain confidentiality and sensitivity, and has speciality according to the management mode of the enterprise. The mainstream report products on the market cannot accurately meet the needs of enterprises.

[0047] Based on this, as shown in Figure 1 The embodiment of the present application provides a heterogeneous report integration method, which comprises the following steps:

[0048] S101: Determine an opened report standard interface, wherein the report standard interface comprises a table sample interface, a formula interface and a data interface.

[0049] Specifically, for the table sample interface, a report table sample analysis method is formulated, and the report table sample analysis method comprises, in sequence, a string, a JSONOBJECT, a JSONARRAY, a List <map>;

[0050] Based on the report template parsing method, obtain the attributes corresponding to the template interface. The attributes corresponding to the template interface include: report data storage table name (tableName), report data set, validation information set, cover code, and cover code reporting data, so that the report data can be stored into the corresponding data table according to tableName.

[0051] For the formula interface, we will develop standard formulas and formula symbols for report analysis to facilitate unified processing of different analysis formulas across different reporting platforms through the publicized standard and formula symbols.

[0052] The content is as follows:

[0053] {

[0054] "report":[

[0055] {

[0056] "formula":[],

[0057] "reportCat":{

[0058] "appcode":"",

[0059] "code":"001",

[0060] "haschildren":false,

[0061] "id":"57ffe6e4-0339-4a25-8246-5ec1031ceb90",

[0062] "name":"Default Group",

[0063] "name_cht":"Default group",

[0064] "name_en":"",

[0065] "name_es":"",

[0066] "name_pt":"",

[0067] "parentid":"CBLSZCY

[0068] },

[0069] "reportFormat":{"cells":[{body}]}

[0070] For the data interface, a report data docking standard is formulated through a json string, and the table data docking standard includes: passing an interface ID, a source ID, a destination ID and issued data, and the data body includes: a task number, a task period, a current level code and business data, so as to define a fixed format to complete the standard interface of the report data.

[0071] According to different business needs, the access requirements of the report are different, and there are different access requirements such as report data, report data + report form, report data + report form + report formula.

[0072] Based on this, the table interface, formula interface and data interface are loosely coupled, the access requirements required by the business needs are determined, and the corresponding interfaces are selected for access according to the access requirements, and the access of the information of the multi-scene report platform is supported.

[0073] S102: receiving heterogeneous report data sent by each report platform through the report standard interface, and analyzing the heterogeneous report data to complete the reconciliation relationship verification.

[0074] As shown in Figure 2 The report platform includes report platform 1 to report platform n, and finally the heterogeneous report data is parsed in the heterogeneous report platform. Different versions and different manufacturers of the report platform are parsed to realize the ontology description, storage and parsing of the data source, combined with the circled index, the concept of data warehouse is referenced, and the enterprise business data is completed and managed.

[0075] S103: managing the heterogeneous report data to realize data classification of the heterogeneous report data based on the concept of data warehouse, and obtaining the enterprise internal report data source.

[0076] The concept of data warehouse refers to a reliable data warehouse system, which needs a clear data hierarchical structure, that is, to ensure the stability of the data layer and shield the influence on the downstream, and to avoid long chain. Combined with these principles and the past project implementation experience, we will uniformly define the hierarchical layer as three layers: operational data layer ODS, common dimension model layer CDM and application data layer ADS.

[0077] ODS (Operational Data Store) is defined as a storage layer, which only retains historical data by technical means (snapshot form) without any conversion, and is isomorphic with the business side DB entity. In structure, it is basically consistent with the incremental or full data of the source system.

[0078] ODS is equivalent to a data preparation area of DW data, while also bearing the basic data recording and historical changes. Its main role is to introduce the basic data into the calculation storage. Based on the concept of dimensional modeling, the consistency of the entire enterprise dimension is established.

[0079] CDM (Common Data Model, Common Dimension Model Layer) is further divided into DWD and DWS. Its main role is to complete data processing and integration, establish consistent dimensions, build reusable detailed fact tables for analysis and statistics, and summarize public granularity indicators.

[0080] Among them, DWD (Data Warehouse Detail): defined as a detailed layer, standardized data (encoding conversion, cleaning, unified format, desensitization, etc.), without horizontal integration.

[0081] Based on the characteristics of each specific business process, the most detailed level of fact table is constructed. You can combine the data usage characteristics of the enterprise to make some important dimension attribute fields of the detailed fact table redundant, that is, to process the wide table (dimension degradation).

[0082] DWS (Data Warehouse Summary): summary layer, associated and integrated with dwd information, output theme wide table (facing business process, different business process information is not redundant construction, using foreign key form). Concentrate on building general dimensions and indicators to reduce business demand development cost.

[0083] Based on the analysis of the theme object as the modeling drive, based on the indicator demand of the upper layer application and product, the public granularity summary indicator fact table is constructed, and the wide table is used to physicalize the model.

[0084] DIM: Dimension table, establish consistent data analysis dimension table, reduce the risk of non-uniform data calculation range and algorithm.

[0085] Based on the dimension as the modeling drive, based on the business meaning of each dimension, through the definition of dimension and dimension primary key, the addition of dimension attribute, the association of dimension, etc. Define the calculation logic and snowflake model, complete the attribute definition process and establish consistent data analysis dimension table. At the same time, you can define the dimension master-sub relationship, the attributes of the sub-dimension will be merged into the master dimension for use, further ensuring the consistency and convenience of the dimension.

[0086] ADS (Application Data Service), customized development for business needs. Contains composite derived indicators and labels.

[0087] Data warehouse implementation process:

[0088] The overall process of data warehouse model design, implementation, construction and online involves data research, model design, model construction, testing and acceptance, and application release. The output and input documents of each stage are specified.

[0089] Data research: The business system and data of the group are checked to understand the current status of the core business data. The business demand is collected and understood, and the index caliber of specific demand is unified. After the functions of the business system or system module involved in the demand are sorted out, the table field level analysis is carried out, and the data is verified to ensure that the existing data can support the business demand.

[0090] Model design: According to the demand and business research results, the model is preliminarily classified, and the appropriate theme domain is selected for model storage; after determining the theme, the design stage of data model is entered, and the logical model design process considers the key problems such as bus structure construction and model specification definition.

[0091] Model construction: Physical model design is based on logical model, taking into account storage performance and other factors to make the physical process of logical model, which is the final physical implementation of logical model. Physical model is generally consistent with logical model, and table structure needs to be output after model design to verify the demand matching. The process of logical model physicalization can be automatically generated by product platform model construction, or it can be completed through business process node custom code development. It includes data mapping, calculation implementation, test verification and other development processes.

[0092] Test acceptance:

[0093] After unit testing, the business needs to be notified together to verify the model data, collect the verification problems, and return the rationality of the model design.

[0094] Release application:

[0095] After the verification, the model can be deployed in the online production environment. On the one hand, it can be connected to the data analysis platform through data source for self-service query and visualization analysis, and on the other hand, it can configure API interface service to provide for business system calling. After online, the model needs to be configured for monitoring to timely grasp the status of data service for business. Model entity and attribute description documents can be published to the users of data warehouse data, so that the model can be better applied.

[0096] Through the combination of report merging technology and data modeling, the report standard interface is developed to realize the access of table format, analysis formula and report data, and to integrate report data of different versions and different storage structures to improve the control ability of the enterprise itself.

[0097] In one embodiment, as the development of the enterprise, a large amount of data information is generated, which is indispensable for the new applications such as enterprise information portal, customer relationship management, data warehouse, decision support and B2B. Before modeling the enterprise data, the business mirror, business requirements and the business problems to be solved are understood. The authenticity of the data source and the standardization of the data are verified, and the data is extracted. According to the determined analysis target, the related data model is built by using the division group method. According to the created data model, the business indicators are circled, and the boundaries are clarified.

[0098] For the reserve nature of the grain industry rotation business, the corresponding enterprise model and specific business indicators are obtained, the enterprise model includes: plan, contract, warehouse, statistical account, quality, finance, and the specific business indicators include: type, planned quantity, contract number, customer name, document number, document quantity, end balance, test value; according to the enterprise model and the specific business indicators, the report standard interface is formed.

[0099] Further, for the reserve nature of the grain industry rotation business, the report platform for receiving the policy grain business and the reserve grain business is inconsistent, and the two business data cannot be summarized and analyzed. At this time, according to the method in the above, it is integrated, the policy grain business and the reserve grain business are analyzed according to the report standard interface, the business indicator data is formed, and the dictionary standard and model filling are realized.

[0100] In one embodiment, the parsing of the heterogeneous report data is recorded, including: parsing report version, manufacturer, parsing time, parsing report data content, recording successful data, and parsing failed data; a repeatTask timing task is added to scan the rpsjcsjl table data state 0 record and reparse. For example, set every 1 hour to scan.

[0101] As shown in Figure 3 The embodiment of the present application further provides a heterogeneous report integration device, comprising:

[0102] At least one processor; and,

[0103] The memory is in communication connection with the at least one processor; wherein,
