In an embodiment of the present invention, as shown in fig. 5, step 101 evaluates performance of a new data source, including:
step 501: and comparing the content of the data file acquired by the old data source with the content of the data file of the new data source to generate a result file, checking the result file by sending service personnel, and evaluating the performance of the new data source based on the checking result.
Specifically, two (or more) data source reconciliation file comparison scripts are written: shell scripts can be written, and a comparison result of two (or more) data source reconciliation files is obtained in a timing operation mode. The inconsistent transactions can be output as text files by comparing the information of the amount, the state and the like of each transaction and stored under a specific directory. After a period of time, after the new data source data is determined to be stable, checking can be performed by using the checking file acquired by the new data source.

Specifically, a switch is added for each data source, so that the starting or stopping of the data source can be controlled, and the data source can be flexibly switched according to actual conditions. If the data source acquisition file is abnormal caused by the account checking file in the account checking process, the data source acquisition file can be switched to other data source acquisition files to perform account checking, and the normal operation of an account checking system is ensured.
In the embodiment of the present invention, as shown in fig. 8, step 103 performs reconciliation processing using the data file acquired by the new data source, including:
Step 801: carrying out standardization processing on the data file to obtain a standardized data file;
Step 802: and (3) carrying out data comparison based on the standardized data file, recording the comparison result, and exporting the recording result to business personnel for subsequent processing.
Specifically, the accounting documents of both the reference party and the reference party, which need to be checked out, are acquired by two (or more) data sources (the checking is based on the data of the reference party). Specific fields in the reconciliation party files are respectively stored in a reference party table and a reference party table of the database through mapping conversion, and the fields of the two tables should be kept consistent. Screening the data in the reference square table and the reference square table for the same batch, comparing the amount of money and the transaction state according to the fields (such as order number, serial number and the like) for identifying the same transaction, recording inconsistent transactions into an error record table, exporting and delivering to service personnel for subsequent processing.
In an embodiment of the present invention, as shown in fig. 9, the method further includes:
step 901: simultaneously acquiring a data file by using the old data source and the new data source;
Step 902: and performing exclusive OR processing on the result of the old data source acquired data file and the result of the new data source acquired data file, and indicating that the file acquisition fails when the old data source and the new data source fail to acquire the data file.

Specifically, a new data source is added, the flow of acquiring reconciliation data by the old data source is not affected, and file acquisition failure should not be returned because of the new data source failure to acquire the reconciliation file. The old data source obtains the account checking file result; or exclusive or processing is carried out in two modes, and failure is judged as failure only if two modes fail to acquire reconciliation data.
If one data source acquisition file is abnormal, the data source acquisition file can be switched to other data source acquisition files, and the normal operation of the whole reconciliation system can not be influenced as long as one data source can be successfully acquired, so that the high availability of the reconciliation system is ensured.
