Embodiment 1
[0039] This embodiment discloses as figure 1 A method for building a bank risk analysis library platform based on big data is shown, and the method includes the following steps:
[0040] S1 Sort out the database table structure of the source system, and design the data application scheme based on the existing data;
[0041] S2 Design the derived layer based on the application requirements, and establish a standard layer based on the application requirements of the derived layer, so as to realize the connection from the source system to the derived layer;
[0042] S3 sorts out the relational mapping table and the processing logic of the derived layer;
[0043] S4 generates data table creation sql, data mapping sql and index processing sql through the metadata management module;
[0044] S5 generates data verification rules sql through metadata classification and modeling, blood relationship and impact analysis, performs rule verification on necessary fields, and performs data...
Embodiment 2
[0055] This embodiment discloses a bank risk analysis library platform based on big data, including a file storage area, a temporary data area, a post source data area, a theme data area, an application data area and an archive data area. image 3 It is a data flow diagram, and the specific description is as follows:
[0056] (1) From the source system to the file storage area: perform batch data synchronization, and the source system will periodically unload the newly added or time-point data to the file storage area on the file server;
[0057] Data acquisition, including real-time and batch methods. The real-time method is for ETL tools to obtain incremental data through the database data exchange component, perform standardized processing and post source integration, and store it in the post source data area; the batch method is for the source system to regularly uninstall new or point-in-time data for file storage on the file server In the area, the data files on the fil...
Embodiment 3
[0065] This embodiment discloses as image 3 The construction method shown mainly includes the following steps:
[0066] (1) Sort out the database table structure of the source system, and clarify the range, frequency and method of data that can be collected. Currently, the range of data that generally needs to be collected is as follows:
[0067]
[0068]
[0069] (2) Design data application schemes based on existing data, including data query, reporting, correlation analysis and data mining, model verification and optimization, risk warning, etc., and design derivative layers based on application requirements.
[0070] (3) Based on the application requirements of the derived layer, establish a standard layer to realize the connection from the source system to the derived layer. The general standard layer construction table is as follows:
[0071]
[0072]
[0073] (4) Sorting out the relational mapping table: By establishing a data mapping relational table and ...
