Detailed Description

Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It should be understood that the description is only exemplary and is not intended to limit the scope of the present disclosure. In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the present disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the concepts of the present disclosure.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The terms "comprises," "comprising," and/or the like, as used herein, specify the presence of stated features, steps, operations, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, or components.

All terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art unless otherwise defined. It should be noted that the terms used herein should be construed to have meanings consistent with the context of the present specification and should not be construed in an idealized or overly formal manner.

Where expressions like at least one of "A, B and C, etc. are used, the expressions should generally be interpreted in accordance with the meaning as commonly understood by those skilled in the art (e.g.," a system having at least one of A, B and C "shall include, but not be limited to, a system having a alone, B alone, C alone, a and B together, a and C together, B and C together, and/or A, B, C together, etc.).

In the technical scheme of the disclosure, the related data (such as including but not limited to personal information of a user) are collected, stored, used, processed, transmitted, provided, disclosed, applied and the like, all conform to the regulations of related laws and regulations, necessary security measures are adopted, and the public welcome is not violated.

In the process of realizing the present disclosure, it is found that after the program for generating the system data file (such as various statistics report forms and upstream and downstream interaction files) according to the service data processing is adapted and modified, the integrity and correctness of the adapting and modifying of the program are generally verified by manually comparing the data files generated before and after the modification. For an electronic information system with a large number of data files, manually checking the number and the content of the files generated by a program after being adapted and modified, and easily checking partial data files when the number of the files is large; when the line record length of the data file is longer (more than 150 bits), the mouse is required to be manually dragged to display one line of data in the screen for checking and checking, so that the checking efficiency is lower; when the data file uses 'invisible characters' as line record line-feeding symbols, the record line-feeding symbols are modified by mistake (for example, the record line-feeding symbols are modified from 0D0A to 0D) when the program is adapted and modified, and the modification difference is difficult to find by manual verification, so that the accuracy of a verification result is not high. Therefore, how to ensure the integrity and the correctness of the system program after the adaptation and transformation aiming at the characteristics of the new database products is a technical problem to be solved in the related technology when the electronic information system is used for database migration.

To this end, an embodiment of the present disclosure provides an application modification policy generation method, including: acquiring target data, wherein the target data represents data required to be processed by a first target application program and a second target application program, the second target application program is obtained by carrying out initial change on the first target application program according to the characteristics of a migrated database, and the second target application program represents an initial application program which is used for realizing the same function as the first target application program; processing target data by calling a first target application program to obtain a first data file; processing the target data by calling a second target application program to obtain a second data file; and performing file comparison operation on the first data file and the second data file, and generating an application program change strategy corresponding to the second target application program.

As shown in fig. 1, an application scenario 100 according to this embodiment may include a first terminal device 101, a second terminal device 102, a third terminal device 103, a network 104, and a server 105. The network 104 is a medium used to provide a communication link between the first terminal device 101, the second terminal device 102, the third terminal device 103, and the server 105.

The first terminal device 101, the second terminal device 102, the third terminal device 103 may be various electronic devices having a display screen and supporting web browsing, including but not limited to smartphones, tablets, laptop and desktop computers, and the like.

The server 105 may be a server providing various services, such as a background management server (by way of example only) providing support for websites browsed by the user using the first terminal device 101, the second terminal device 102, and the third terminal device 103. The background management server may analyze and process the received data such as the user request, and feed back the processing result (e.g., the web page, information, or data obtained or generated according to the user request) to the terminal device.

For example, the server 105 may obtain the target data, call the first target application program to process the target data to obtain a first data file, call the second target application program to process the target data to obtain a second data file, and finally perform a file comparison operation on the first data file and the second data file to generate an application program change policy corresponding to the second target application program.

Accordingly, the application change policy generating apparatus provided by the embodiments of the present disclosure may also be provided in a server or a server cluster that is different from the server 105 and is capable of communicating with the first terminal device 101, the second terminal device 102, the third terminal device 103, and/or the server 105.

It should be understood that the number of terminal devices, networks and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.

The application change policy generation method according to the embodiment of the present disclosure will be described in detail below with reference to fig. 2 to 6 based on the scenario described in fig. 1.

Fig. 2 schematically illustrates a flowchart of an application change policy generation method according to an embodiment of the present disclosure.

As shown in fig. 2, the method 200 includes operations S210 to S240.

In operation S210, target data is acquired.

According to the embodiment of the disclosure, the target data may represent data to be processed by the first target application program and the second target application program, where the second target application program is obtained by performing initial modification on the first target application program according to the characteristics of the migrated database, and the second target application program may represent an initial application program for implementing the same function as the first target application program.

Database migration refers to migrating an electronic information system from one database to another, in accordance with embodiments of the present disclosure. The service requirements before and after the migration of the electronic information system are unchanged, i.e. the same functions as before the migration of the electronic information system are still required to be realized. For example, for a database before migration, the electronic information system may generate ten reports, and for a database after migration, the electronic information system also needs to generate ten reports, where data displayed by each report is the same as data displayed by a report corresponding to the database before migration.

According to the embodiment of the disclosure, in the case that an application program in the electronic information system adapts to a certain database characteristic, the electronic information system can acquire data from the database and process the data, so that a corresponding function is realized. Therefore, after the electronic information system is changed from one database to another, the migrated database does not support the original application program in the electronic information system due to the change of the characteristics of the database, and the application program also needs to be correspondingly changed to be changed into the application program supported by the migrated database.

According to the embodiment of the disclosure, the first target application program may represent an application program matched with the characteristics of the database before migration, and the second target application program may represent an initial application program obtained by performing initial modification on the first target application program according to the characteristics of the database after migration, and because a missing program or an error program may exist in the second target application program obtained by performing initial modification, verification on the integrity and the correctness of the second target application program is required, that is, verification on whether the second target application program is completely matched with the characteristics of the database after migration.

According to the embodiment of the disclosure, the service requirements before and after the migration of the electronic information system are unchanged, that is, the system data files obtained by processing the service data in the database before and after the migration of the electronic information system are consistent, the same target data can be obtained from the service data in the database, and the integrity and the correctness of the first target application program can be verified.

In operation S220, the target data is processed by calling the first target application program to obtain a first data file.

According to the embodiment of the disclosure, the target data can be processed by calling an application program corresponding to the target data in the first target application program to obtain a first data file corresponding to the target data, wherein the first data file can represent a data file obtained for the target data before the migration of the electronic information system.

In operation S230, the target data is processed by calling the second target application program to obtain a second data file.

According to the embodiment of the disclosure, the target data can be processed by calling an application program corresponding to the target data in the second target application program to obtain a second data file corresponding to the target data, wherein the second data file can represent a data file obtained for the target data after the electronic information system is migrated.

According to the embodiment of the disclosure, in the case that the second target application program is matched with the characteristics of the database after migration, the functions that can be achieved by the first target application program and the second target application program are identical, that is, the data files obtained by processing the same target data are identical. Therefore, in order to verify the integrity and correctness of the adaptation modification of the second target application program, the first target application program and the second target application program can be respectively called to process the same target data, so as to obtain a first data file and a second data file.

According to an embodiment of the present disclosure, the first target application and the second target application need to be invoked according to the same input parameters, such that the first target application and the second target application are processing the same batch of target data. For example, the input parameters may include a date of a particular day, and the first target application and the second target application may be invoked to process target data at that date.

In operation S240, a file comparison operation is performed on the first data file and the second data file, and an application change policy corresponding to the second target application is generated.

According to the embodiment of the disclosure, the obtained first data file and the second data file are subjected to file comparison operation, so that an application program change strategy corresponding to the second target application program can be generated. Under the condition that the first data file is consistent with the second data file, the characteristic of the second target application program is matched with that of the migrated database, and the second target application program is not required to be changed; when the first data file is inconsistent with the second data file, it may indicate that there is a missing program or an error program in the second target application program, and then the second target application program needs to be changed according to the application program change policy.

According to the embodiment of the disclosure, the first data file can be obtained by calling the first target application program to process target data, the second data file can be obtained by calling the second target application program to process target data, wherein the second target application program is obtained by initially changing the first target application program according to the characteristics of the migrated database, and the first data file and the second data file are subjected to file comparison operation, so that the integrity and the correctness of the second target application program can be verified, and the missing program and the error program in the second target application program are changed according to the generated application program changing strategy corresponding to the second target application program, thereby improving the integrity and the correctness of the second target application program.

According to an embodiment of the present disclosure, the above application program change policy generating method further includes: under the condition of performing first file comparison operation, copying and migrating the business data in the first database to a second database and a backup database to obtain the business data in the second database and the backup database; and under the condition of carrying out non-primary file comparison operation, carrying out repair operation on the data to be repaired, wherein the data to be repaired is changed in the data states of the first database and the second database, by utilizing the service data in the backup database.

According to embodiments of the present disclosure, the first database may characterize the pre-migration database and the second database may characterize the post-migration database.

According to the embodiment of the disclosure, after the electronic information system is migrated to the second database, the first target application program needs to be initially changed according to the characteristics of the second database to obtain a second target application program. Before verifying the integrity and correctness of a part of the application program in the second target application program, that is, before performing the first file comparison operation, the business data in the first database needs to be copied and migrated to the second database and the backup database, and under the condition that the business data in the first database is copied and migrated to the second database and the backup database, the same target data can be obtained from the first database and the second database, and the integrity and correctness of the application program corresponding to the target data in the second target application program are verified.

According to the embodiment of the disclosure, when the application program corresponding to the target data in the second target application program has a missing program or an error program, the second target application program can be changed according to the generated application program changing policy, so as to obtain a new second target application program. And verifying the integrity and correctness of the obtained new second target application program, namely performing non-first file comparison operation. However, the data in the first database and the second database triggers the operation of the first target application program and the second target application program due to the previous file comparison operation, which may cause the data states in the first database and the second database to change (also referred to as data pollution or dirty data), and the data in the first database and the second database needs to be repaired, so that the data bases in the first database and the second database are kept consistent, and the next file comparison operation can be started.

According to the embodiment of the disclosure, in the case of verifying the integrity and correctness of the second target application program, the target data may be processed by calling the first target application program and the second target application program, but the state of the target data in the first database or the state of the target data in the second database may be changed. For example, the business requirements before and after the migration of the electronic information system may include generating an invoice report, and the application program may be invoked to process the data corresponding to the business requirements to generate a corresponding data file. Where the data file may characterize the generated invoice statement, which may indicate that this data has been invoiced, the status of the data in the database may be updated to invoiced. In the case of the above-described base, the application program is called again to process the data, and a data file is not reproduced but an empty file is generated, so that the file comparison operation cannot be performed. Therefore, in the case of performing the non-first file comparison operation, it is necessary to restore the data to be processed to the original state so that the data in the database before and after migration remain consistent.

According to embodiments of the present disclosure, the state of the business data in the backup database may remain as original. Therefore, under the condition of carrying out non-first file comparison operation, the service data in the backup database can be utilized to carry out repair operation on the data to be repaired, wherein the data state of the data in the first database and the data state in the second database are changed.

According to embodiments of the present disclosure, data may be replicated by DRS (Data Replication Service) data replication techniques, or may be achieved by exporting sql (Structured Query Language ) data files from a post-migration database, and playing back the sql data files from a pre-migration database.

According to the embodiment of the disclosure, the repair speed of the data to be repaired also affects the verification efficiency of the adaptation and transformation integrity and correctness of the second target application program, so that the service data in the backup database can be utilized to repair the data to be repaired, the data in the database before migration and the data in the database after migration can be quickly restored to be consistent in data basis, and the problem that the data in the database before migration and the data in the database after migration are polluted in the previous round of file comparison operation process can be solved, so that the data file is convenient to generate for the subsequent file comparison operation.

According to an embodiment of the present disclosure, in a case of performing a non-first file comparison operation, performing a repair operation on data to be repaired, in which a data state of data in a first database and a second database is changed, using service data in a backup database, including: under the condition that data to be repaired exist in the first database or data to be repaired exist in the second database, the data corresponding to the data to be repaired in the first database and the second database are emptied; copying data corresponding to the data to be repaired from the business data in the backup database to the first database and the second database.

According to the embodiment of the disclosure, in the case of performing the non-first file comparison operation, it is required to determine whether there is data with changed states, i.e., data to be repaired, in the first database and the second database. Under the condition that the data to be repaired does not exist in the first database and the second database, the data in the first database and the second database do not need to be repaired.

According to the embodiment of the disclosure, when the data to be repaired exists in the first database or the data to be repaired exists in the second database, the data corresponding to the data to be repaired in the first database and the second database can be firstly emptied, and the data corresponding to the data to be repaired is copied from the service data in the backup database to the first database and the second database.

According to the embodiment of the disclosure, under the condition of performing non-first file comparison operation, the service data in the backup database can be utilized to repair the data to be repaired, the data in the first database and the second database are changed, the data in the first database and the second database can be quickly restored to be consistent, and the problem that the data in the first database and the second database are polluted in the previous file comparison operation process can be solved.

According to an embodiment of the present disclosure, processing target data by calling a first target application program to obtain a first data file includes: grouping first target application programs according to preset rules to obtain a plurality of first application programs, wherein the first target application programs can represent programs for processing business data; and processing the target data by calling at least one first application program to obtain a first data file, wherein the at least one first application program can represent a program for processing the target data in the first target application program, and the service data can comprise the target data.

According to embodiments of the present disclosure, the preset rules may characterize data dependencies. The first target application programs can be grouped according to the data dependency relationship to obtain a plurality of first application programs, wherein each first application program has no dependency relationship and can be independently called. For example, business data manipulation is data dependent, and for an application, the business requirements that the application needs to implement may characterize writing acquired table data to a data file on a temporary directory and moving the data file from the temporary directory copy to a target directory. The application programs can be grouped according to the data dependency relationship to obtain an A program, a B program and a C program, wherein different programs have different functions, the A program can be used for acquiring the table data, the B program can be used for writing the table data into a data file and writing the data file into a temporary directory, and the C program can be used for copying and moving the data file from the temporary directory to a target directory.

According to the embodiment of the disclosure, the target data may be processed by calling at least one first application program to obtain a first data file, wherein the at least one first application program may represent a program for processing the target data in the first target application program. For example, the first target application may be grouped to obtain 20 first applications, and then at least one first application may include 2 first applications, and may further include 5, 10, 15, or 20 first applications.

According to the embodiment of the disclosure, the first target application programs are grouped to obtain the plurality of first application programs, so that the granularity of a single first application program can be supported to perform real-time file comparison operation, and after the data depended on at least one first application program to be called is acquired, the at least one first application program can be called to perform file comparison operation, and the file comparison operation is not required to be performed after all the data depended on the first target application program are acquired.

According to an embodiment of the present disclosure, processing target data by calling a second target application program to obtain a second data file includes: grouping the second target application programs according to a preset rule to obtain a plurality of second application programs, wherein the second target application programs can represent programs for processing business data; and processing the target data by calling at least one second application program to obtain a second data file, wherein the at least one first application program can characterize a program used for processing the target data in the second target application program.

According to the embodiment of the disclosure, the second target application programs can be grouped according to the same data dependency relationship to obtain a plurality of second application programs, wherein each second application program does not have the dependency relationship and can be independently called.

According to the embodiment of the disclosure, the target data may be processed by calling at least one second application program to obtain a second data file, wherein the at least one second application program may characterize a program for processing the target data in the second target application program. For example, the second target application programs may be grouped to obtain 20 second application programs, and then at least one second application program may include 2 second application programs, and may further include 5, 10, 15, or 20 second application programs.

According to the embodiment of the disclosure, the second target application programs are grouped to obtain the plurality of second application programs, so that the granularity of a single second application program can be supported to perform real-time file comparison operation, and after the data depended on at least one second application program to be called is acquired, the at least one second application program can be called to perform file comparison operation, and the file comparison operation is not required to be performed after all the data depended on the second target application program are acquired.
