The terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning that is consistent with their contextual meaning in the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein in various embodiments of the present invention.
Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic flowchart of a data subscription method provided in an embodiment of the present application. The data subscription method is applied to a proxy subscription device, wherein the proxy subscription device is connected with a source data device and at least one user end device, and the data subscription method comprises the following steps:
step S101, monitoring whether each source data theme corresponding to the source data equipment is updated.
The source data theme refers to various data themes provided by a producer, namely source data equipment, and data corresponding to the source data theme is source data. For example, in the area of merchandise supply and marketing, the source data topics may be: a supplier topic, a commodity topic, a customer topic, and a warehouse topic. The commodity theme can include various source data for recording the purchasing condition of supermarket commodities, the selling condition of the commodities and the storage condition of the commodities, the client theme includes but is not limited to various source data related to the commodities purchased by the client, and the warehouse theme can include various source data such as the storage condition of the commodities in the warehouse and the management condition of the warehouse.
In specific implementation, whether each source data theme corresponding to the source data device is updated or not may be monitored continuously or at certain preset time intervals. The preset time can be customized according to the actual use requirement of the user and the specific application scene, and is not further limited here.
And step S102, obtaining incremental data corresponding to each source data theme.
If it is monitored that the topic address broadcasted by the source data device for publishing the source data topic generates new incremental data, the source data topic is updated. At this time, the source data obtaining request may be sent to the source data device to receive the source data returned by the source data device according to the source data obtaining request. The source data device may also be set in advance to: and if the incremental data are generated, the incremental data are directly sent to the proxy subscription equipment, and the proxy subscription equipment is not required to send a corresponding request to the source data.
Step S103, performing data processing of a preset type on the incremental data to obtain business data corresponding to business data topics, wherein the data processing of the preset type comprises integration, decomposition and conversion, and each business data topic is associated with at least one source data topic.
The service data theme is a theme which is provided by an agent, namely the agent subscription device, to the user terminal device for subscription, and the data corresponding to the service data theme is service data.
In the source data topic, the source data device publishes all the generated source data to the source data topic, so that there is a large amount of data that cannot be directly used by the user end device or is not required by the user end device in the source data received by the proxy subscription device. The agent subscription device processes the source data topics which can be subscribed by the user terminal device according to services, scenes and the like, and then sends service data topics which are suitable for service understanding and can be directly subjected to subsequent processing to the user terminal device. The user end device can directly subscribe interested business data topics from the proxy subscription device according to business needs. The following further describes the data processing procedures of different preset types respectively:
1. the step of integrating the data processing of the preset type, and performing the data processing of the preset type on the incremental data to obtain the business data corresponding to the business data theme comprises the following steps:
if the business data theme is associated with at least two source data themes, combining the first metadata corresponding to each source data theme to obtain second metadata corresponding to the business data theme;
the first metadata is used for indicating a storage area of source data corresponding to a source data theme, and all source data corresponding to the second metadata are service data corresponding to the service data theme.
Specifically, each business data topic is associated with at least one source data topic, that is, the association relationship between the business data and the source data topic may be any one of one-to-one, one-to-many, and many-to-one. If the business data theme is associated with at least two source data themes, the association relationship between the business data theme and the source data theme is one-to-many.
Metadata, also called intermediate data or relay data, is data for describing data, and mainly describes information of data attributes, such as functions of indicating storage locations, history data, resource lookup, file recording, and the like. If a plurality of source data themes need to be integrated into one service data theme, the source data corresponding to the second metadata can be sent to the user end equipment by the proxy subscription equipment in a mode of combining the first metadata corresponding to the source data themes into the second metadata, and meanwhile, the change of storage addresses or storage spaces for storing the source data is reduced.
2. The step of converting the data processing of the preset type, and performing the data processing of the preset type on the incremental data to obtain the business data corresponding to the business data theme comprises the following steps:
and according to a preset first mapping relation between the first field and the second field, converting the first field in the incremental data into the corresponding second field through field mapping to obtain the business data corresponding to the business data theme.
The structure and format of the source data sent by the source data device to the proxy subscription device may not be consistent with the structure and format of the data that can be received by the user end device. Therefore, the source data needs to be converted into service data that can be received by the customer premise equipment according to a certain corresponding relationship.
Specifically, a data field in the source data may be defined as a first field, and a data field in the service data that can be received by the customer premise equipment may be defined as a second field. According to a first mapping relation between a first field and a second field for presetting settings, incremental data corresponding to a source data theme are converted into business data through field mapping. The first mapping relationship may be customized according to the actual use requirement of the user and the specific application scenario, and is not specifically limited herein.
3. If one source data theme can be converted into a plurality of service data themes, that is, the incidence relation between the source data theme and the service data theme is one-to-many, the source data of the original source data theme can be decomposed into data of the plurality of service data themes according to the screening rule and the field mapping.
Step S104, according to the business data acquisition request sent by each customer premise equipment and the preset subscription relationship between the business data theme and each customer premise equipment, the business data is sent to the corresponding customer premise equipment.
In specific implementation, the creating step of the preset subscription relationship includes:
receiving a subscription request sent by user end equipment, wherein the subscription request comprises a service data theme needing subscription and an equipment identifier corresponding to the user end equipment;
and creating the preset subscription relationship according to the subscription request, wherein the preset subscription relationship comprises a second mapping relationship between the equipment identifier and the service data topic needing to be subscribed.
By establishing a second mapping relation between the service data theme and the device identifiers of different user end devices, the service data corresponding to the service data theme can be sent to the corresponding user end devices, so that the user end devices subscribe the service data theme and obtain the corresponding service data based on the service data theme. The device identifier may be a set of strings used to characterize the uniqueness of the client device, including but not limited to the device number and I P address.
The method comprises the following steps of sending the service data to the corresponding customer premise equipment according to a service data acquisition request sent by each customer premise equipment and a preset subscription relationship between the service data theme and each customer premise equipment, wherein the steps comprise:
judging whether the user side equipment corresponding to the business data theme is inspection-free equipment or not;
if the user end equipment corresponding to the business data theme is not the inspection-free equipment, verifying a business data acquisition request sent by the user end equipment, wherein the business data acquisition request comprises an equipment identifier and a request timestamp corresponding to the business data acquisition request;
and if the verification is successful, the business data corresponding to the business data theme is sent to the user side equipment corresponding to the equipment identification.
After step S103, it may be determined whether the customer premise equipment corresponding to the service data topic is a non-inspection device. If the customer premise equipment corresponding to the business data theme is the non-inspection equipment, or the customer premise equipment corresponding to the business data theme is not the non-inspection equipment but the inspection is successful, the business data can be sent to the customer premise equipment according to the second mapping relation.
Specifically, a non-inspection device list may be preset, where device identifiers corresponding to all non-inspection devices are stored in the non-inspection device list. And indexing based on the inspection-free equipment list, and judging whether the equipment identification in the second mapping relation corresponding to the service data theme exists in the inspection-free equipment list or not. If the user end equipment corresponding to the business data theme is the inspection-free equipment, the user end equipment corresponding to the business data theme is not the inspection-free equipment.
The preset subscription relationship comprises a subscription authorization time interval, and the step of verifying the service data acquisition request sent by the user end equipment comprises the following steps:
if the equipment identification in the service data acquisition request is the same as the equipment identification in the preset subscription relationship, judging whether the request timestamp is in the subscription authorization time interval;
if the request timestamp is within the subscription authorization time interval, judging that the verification is successful;
and if the request timestamp is not in the subscription authorization time interval, judging that the verification fails.
Specifically, when the preset subscription relationship is created, a subscription authorization time interval may be added to the subscription request sent by the user end device. The subscription authorization time interval refers to an effective time period for the user end device to authorize the proxy subscription device to perform proxy subscription, and may also be a time interval for the proxy subscription device to specify the time interval for sending the processed service data to the user end device according to a pre-established contract or a contract. Within this time interval, the proxy subscribing device may perform a proxy process of "obtaining incremental data and sending the processed incremental data to the customer premise equipment".
After the service data acquisition request sent by the user end device, it may be determined whether the device identifier in the service data acquisition request is the same as the device identifier in the preset subscription relationship. If the request time stamps are the same, judging whether the request time stamps are in the subscription authorization time interval, if the request time stamps are in the subscription authorization time interval, judging that the verification is successful, and if the request time stamps are not in the subscription authorization time interval, judging that the verification is failed. And if the verification is successful, the business data corresponding to the business data theme is sent to the user end equipment. The request timestamp refers to a time corresponding to the service data acquisition request sent by the user end device to the proxy subscription device, and the accuracy of the request timestamp may be customized according to the actual use requirement of the user or a specific application scenario, for example, a second, a minute, or an hour, and is not further limited herein.
