Background
Under the current economic condition, along with the expansion of the service range, in the process of business operation of enterprises, more and more enterprises can have the requirements of system connection or data exchange between business partners, cross-system data transmission becomes necessary, when business data interaction is processed between heterogeneous systems, the system interface is generally corresponding to other system interfaces through Webservice or WebAPI, and the business data of other heterogeneous systems are automatically downloaded to the system by using a scheduling strategy polling service mode.
In the existing ERP software, data among different systems are isolated from each other, and meanwhile, because the data are different business systems, the data are not upstream and downstream documents in the same system, have no association relationship and are independent from each other. When the amount of documents is large and the download frequency is high, the following will occur: when the same service data is not downloaded, the unfinished service data is downloaded again due to the too high trigger frequency of the trigger download, that is, the service data is repeatedly downloaded to the local system.
In the existing scheme, because the systems of the two parties are heterogeneous and the service data does not have an association relationship with each other, the repeatedly downloaded service data can take effect repeatedly. If the service data is used for material ordering, repeated material ordering can occur due to repeated downloading of the service data, so that great economic loss and business disputes are caused. In the existing scheme, repetition can only be checked manually, time and labor are wasted, and efficiency is low.

For convenience of understanding, a specific flow in the embodiment of the present invention is described below, and referring to fig. 1, an embodiment of a data download management method in the embodiment of the present invention may include:
101. converting the target service data into a corresponding byte stream;
the data downloading management method in the embodiment of the invention is mainly applied among heterogeneous systems, wherein the heterogeneous systems refer to a set of a plurality of related systems, the data downloading and accessing can be realized among the heterogeneous systems, and meanwhile, each system still keeps own application characteristics, integrity control and security control. The embodiment of the present invention takes the first service system as a data storage party and the second service system as a data downloading party as an example for explanation.
The first service system is a data storage party, the first service system can convert each service data into a corresponding byte stream respectively so as to facilitate data transmission, and when the target service data needs to be transmitted to the second service system, the first service system can convert the target service data into the corresponding byte stream.
102. Generating an identifier corresponding to the target service data according to the byte stream of the target service data;
due to mutual independence between heterogeneous systems, in the data downloading process, the unique identifier of the service data in the first service system cannot be identified by the second service system. In order to avoid repeated downloading of data, in the embodiment of the present invention, after the service data is converted into the corresponding byte stream, the byte stream of each service data needs to be calculated according to a preset algorithm, and an identifier corresponding to each service data is generated, so as to perform unique identification in the second service system.
Optionally, in the embodiment of the present invention, a preset algorithm may be used to calculate all bytes of a byte stream corresponding to target service data, or calculate target data composed of partial bytes in the byte stream, where the target data is a part of the entire byte stream, and the target data may uniquely identify corresponding service data in the second service system. For example, the target data may be a document number or an invoice code of the business data in the second business system, and the like, which is not limited herein.
Preferably, as a possible implementation manner, in the embodiment of the present invention, the first service system extracts target data in the byte stream, where the target data is a unique identifier of the service data in the first service system; and the first service system adopts a preset algorithm to calculate the target data to generate a corresponding identifier.
Optionally, the first service system extracts data in a preset sequence in the byte stream as target data; or, the first service system identifies a preset field in the byte stream and extracts data of preset bytes after the preset field as target data. In practical application, when generating the service data in the first service system, the standardized service data may be generated according to the same format, after the standardized service data is converted into the byte stream, the sequence of the unique identification data corresponding to the service data in the second service system in the byte stream is fixed, and the first service system extracts the data in the preset sequence in the byte stream as the target data. In addition, in this embodiment of the present invention, a uniform identifier may be set in a byte before (after) the unique identification data of the service data, the uniform identifier is also the same preset field after being converted into the byte stream, and the first service system identifies the preset field in the byte stream and extracts data of the preset byte after (before) the preset field as the target data.
Optionally, the preset algorithm in the embodiment of the present invention may be an MD5 algorithm, an SHA1 algorithm, or a mixed algorithm of MD5 and SHA1, where the specific algorithm is not limited here, and only needs to ensure that operation results obtained after different data are calculated by the preset algorithm are not repeated.
103. Sending the identifier corresponding to the target service data to a second service system;
in the embodiment of the invention, in order to identify the repeated downloading condition before the data downloading is completed, the first service system sends the byte stream corresponding to the target service data to the second service system, or sends the byte stream corresponding to the target service data to the second service system, and simultaneously sends the identifier corresponding to the target service data to the second service system, so that the second service system can identify whether the data is repeatedly downloaded before the data downloading is completed.
Specifically, the first service system may send the identifier corresponding to the target service data to the second service system separately; the first service system may also use the identifier as a part of the byte stream corresponding to the target service data, and send the identifier corresponding to the target service data to the second service system while sending the byte stream corresponding to the target service data, which only needs to ensure that the second service system receives the identifier corresponding to the target service data before completing the receiving process of the whole byte stream of the target service data, and the specific details are not limited herein.
104. Receiving an identifier corresponding to target service data sent by a first service system;
after the identifier corresponding to the target service data transmitted by the first service system, the second service system may receive the corresponding identifier.
105. And judging whether the identifier corresponding to the target service data is overlapped with the identifier stored by the identifier.
In order to save network bandwidth resources, the second service system judges whether the identifier corresponding to the target service data is overlapped with the identifier stored by the second service system before completing the reception of the byte stream of the target service data. If the identifier corresponding to the target service data is not repeated with the stored identifier, indicating that repeated downloading does not exist, executing step 106, and storing the identifier corresponding to the target service data before completing the reception of the byte stream of the target service data, so as to facilitate subsequent identification; if the identifier corresponding to the target service data is determined to be the same as the stored identifier, indicating that the download is repeated, step 107 is executed to stop receiving the byte stream of the target service data.
106. Storing an identifier corresponding to the target service data;
107. the reception of the byte stream of the target service data is stopped.
In the embodiment of the invention, when the second service system downloads the service data stored in the first service system, the first service system respectively converts each service data into the corresponding byte stream, respectively generates the identifier corresponding to each service data according to the byte stream and sends the identifier to the second service system, the second service system can judge whether the identifier of the target service data is repeated with the identifier stored in the second service system before completing the reception of the byte stream of the target service data, if so, the downloaded service data is downloaded, and the second service system stops downloading the target service data.
On the basis of the implementation shown in fig. 1, in the embodiment of the present invention, in order to identify the downloaded service data, the downloaded data needs to be marked.

203. sending the identifier corresponding to the target service data to a second service system;
204. receiving an identifier corresponding to target service data sent by a first service system;
205. and judging whether the identifier corresponding to the target service data is overlapped with the identifier stored by the identifier.
206. Storing an identifier corresponding to the target service data;
207. stopping receiving the byte stream of the target service data;
the content described in steps 201 to 207 in the embodiment of the present invention is similar to the content described in steps 101 to 107 in the embodiment shown in fig. 1, and please refer to steps 101 to 107 specifically, which is not described herein again.
208. And after receiving the byte stream of the target service data, updating the downloading state of the target service data into the downloaded state.
Optionally, after downloading each service data, the second service system may update the downloading state of the corresponding service data to the downloaded state. After the processing, the second service system can identify the downloaded data without waiting for receiving the identifier, and can further avoid repeated downloading of the data.
In the embodiment of the invention, when the second service system downloads the service data stored in the first service system, the first service system respectively converts each service data into the corresponding byte stream, and respectively generates the identifier corresponding to each service data according to the byte stream, the second service system can judge whether the identifier of the target service data is repeated with the identifier stored in the second service system before completing the reception of the byte stream of the target service data, if so, the downloaded service data is downloaded, and the second service system stops downloading the target service data.
Secondly, in this embodiment, a downloading state of the data may also be set, and after each service data is downloaded, the downloading state of the corresponding service data is updated to be the downloaded state, and the second service system may identify the downloaded data without calculating the byte stream, so as to further avoid repeated downloading of the data.
