Abstract
The specification discloses a method and a device for sending data, wherein before data is acquired according to an acquisition request of a terminal, a source of each data in a target data subset corresponding to the acquisition request is determined by setting a placeholder; and then acquiring the data corresponding to the acquisition request from the data corresponding to the full set identifier according to the data source recorded in the placeholder corresponding to each data in the target data subset.

Description
Technical Field
The present disclosure relates to the field of internet, and in particular, to a method and an apparatus for transmitting data.
Background
At present, with the rapid development of new technological revolution represented by information and communication technology, the application of the internet has been expanded to many fields of social life.
In the prior art, for example, in a scenario where a terminal acquires target data from multiple data sources through a server, after receiving a request from the terminal, the server acquires to-be-processed data, which is equal to the target data, from each data source according to an amount of the target data corresponding to the request, and then the total amount of the to-be-processed data received by the server from each data source is significantly greater than an amount of the target data actually requested by the terminal. Then, the server extracts the data to be processed corresponding to the amount of the target data from the data to be processed according to a preset data extraction rule, the data to be processed is used as the target data and is sent to the terminal, and the data to be processed which is not extracted is discarded.
It can be seen that, in the method for sending data in the prior art, the total amount of the data to be processed, which is received by the server from each data source, is significantly greater than the amount of the target data actually requested by the terminal, thereby causing a data redundancy phenomenon. Further, under the condition that the number of the data sources corresponding to the server is large, for a request, the amount of the to-be-processed data acquired by the server will be larger, so that the amount of the to-be-processed data discarded finally is correspondingly increased, and the phenomenon of data redundancy is more serious.

Detailed Description
In order to make the objects, technical solutions and advantages of the present disclosure more clear, the technical solutions of the present disclosure will be clearly and completely described below with reference to the specific embodiments of the present disclosure and the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the specification without making any creative effort belong to the protection scope of the specification.
The technical solutions provided by the embodiments of the present description are described in detail below with reference to the accompanying drawings.
Fig. 1 is a first process for sending data provided in an embodiment of this specification, which may specifically include the following steps:
s100: and receiving an acquisition request aiming at the target data subset sent by the terminal. The acquisition request includes: a full set identification of a full set of data to which the target subset of data belongs and a subset identification of the target subset of data.
In this specification, the target data subset may be a data set composed of data corresponding to the acquisition request. The data corpus may be a set of all data in the current application scenario, including the data corresponding to the acquisition request. The target data subset is a subset of the data corpus, and the subset identification of the target data subset is used for distinguishing data in the data corpus belonging to the target data subset from data in the data corpus belonging to other data subsets. For example, when the technical solution in this specification is applied to a user selecting a commodity through a terminal, the corpus identifier may be a commodity keyword (e.g., coffee) input into the terminal by the user, and the data corpus is a set of data corresponding to the commodity keyword in the data source; the subset identification may be a screening condition (e.g., page number 2) for data in the corpus of data, and the target subset of data is the set of data in the corpus of data corresponding to coffee corresponding to page 2.
Specifically, the operation of receiving the acquisition request may be performed by the server. The terminal may include, but is not limited to, a mobile phone, a tablet Computer, a Personal Computer (PC), a vehicle with a driving assistance function, an unmanned vehicle, an unmanned aerial vehicle, and the like.
S102: determining a placeholder corresponding to each data in the full set of data corresponding to the full set identification.
For each data in the data corpus, the data's corresponding placeholder can be used to characterize the source of the data. For example, the placeholder for the data may be an identification of the data source to which the data belongs (e.g., identification of a data source is S1). Each data corresponding to the data corpus can be distinguished at least by the source of the data.
S104: and sorting the placeholders corresponding to each datum according to a preset sorting rule.
The preset ordering rule determines the order of the placeholders in the data corpus.
Optionally, the preset sort rule may be configuration data that is pre-loaded in the server, and a controller of the server may design the preset sort rule by changing the configuration data.
S106: and dividing the sorted placeholders according to the sorted placeholders and a preset subset division rule so as to determine a data subset to which the data corresponding to each sorted placeholder belongs.
The preset subset partition rule may be used to determine the number of data included in the data subset, and further, the preset subset partition rule may be used to limit the number of placeholders corresponding to the data included in the data subset. For example, when the technical solution in this specification is applied to a user selecting a commodity through a terminal, a preset subset partitioning rule may be used to determine the number of commodities contained in each page displayed to the user.
In this step, the placeholders have a certain sequence in the sequence formed by sorting, and the data subsets determined for the placeholders also have a corresponding sequence on the basis. For example, when the technical solution in this specification is applied to a user selecting a commodity through a terminal, the sequence of each data subset may be embodied by page number ordering of each data subset in a page displayed to the user.
S108: and determining a placeholder corresponding to the data belonging to the target data subset corresponding to the subset identification as a designated placeholder.
For example, when the technical solution in this specification is applied to a user selecting a commodity through a terminal, the user sends an acquisition request through the terminal, a subset in the acquisition request is identified as page number 2, and the server locates, in each data set having a certain sequence, a target data subset corresponding to page number 2, and determines a placeholder in the target data subset as a designated placeholder.
S110: and acquiring data corresponding to the designated placeholder in the data corresponding to the full set identifier.
The designated placeholder at least includes the identifier of the data source to which the data corresponding to the designated placeholder belongs, and the server can acquire the data corresponding to the designated placeholder from the data source according to the identifier of the data source corresponding to the designated placeholder.
S112: and returning the target data subset corresponding to the acquired data to the terminal.
For example, when the technical solution in this specification is applied to a user selecting a commodity through a terminal, the target data subset returned to the terminal by the server is: the data set composed of the data corresponding to the keyword coffee is divided into data on page 2.
The method of transmitting data described in this specification will be described in detail below.
As shown in fig. 2, in this specification, a network architecture includes a terminal, a server, and a data source. The server is in communication connection with the terminal and the data source respectively, and then the server can acquire corresponding data from the data source according to the acquisition request of the terminal, process the acquired data to acquire a target data subset corresponding to the acquisition request, and then return the target data subset to the terminal.
The data corpus comprises at least part of data stored in a plurality of data sources. When the technical scheme in the specification is applied to a user selecting a commodity through a terminal, data of the same type are generally stored in the same data source, for example, commodity information is stored in one data source, and comments on the commodity are stored in another data source.
Specifically, determining the placeholder corresponding to each data in the full set of data corresponding to the full set identifier may include: and for each data source, determining the quantity of the data belonging to the data corpus contained in the data source, and generating the quantity of placeholders corresponding to the data source as placeholders corresponding to the data belonging to the data corpus contained in the data source.
When the technical scheme in the specification is applied to a user selecting a commodity through a terminal, the server determines the quantity of data corresponding to the commodity, which are stored in each data source, according to the acquisition request. For example, the data sources are S1, S2, S3, and S4, and the data sources S1 to S4 respectively include the following data corresponding to the commodity: 3. 1, 5 and 2. The number of placeholders determined by the server for the data corresponding to the item in the data sources S1-S4, respectively, is: 3, 1, 5 and 2. And recording the placeholders corresponding to the data source S1 as S1, the placeholders corresponding to the data source S2 as S2, the placeholders corresponding to the data source S3 as S3, and the placeholders corresponding to the data source S4 as S4.
Then, the server sorts the placeholders corresponding to the data sources according to a preset sorting rule. For example, the ordering rule is: placeholders corresponding to the data source S1 and placeholders corresponding to the data source S2 are arranged in a mixed manner, placeholders corresponding to the data source S3 are located behind placeholders corresponding to the data source S1 and the data source S2 in the sequence obtained by sorting, and placeholders corresponding to the data source S4 are located behind placeholders corresponding to the data source S3 in the sequence obtained by sorting. The sequence of placeholders obtained after sorting may be: pn ═ s1, s2, s1, s1, s3, s3, s3, s3, s3, s 4.
And dividing the sorted placeholders according to the sorted placeholders and a preset subset division rule, wherein the preset subset division rule can be configuration data loaded in the server when determining the data subset to which the data corresponding to each placeholder belongs. The preset subset partition rule may also be determined by the server from an acquisition request sent by the terminal. For example, if the preset subset partition rule is that the number of data included in each data subset is 5, the number of placeholders corresponding to each data subset is 5. After the sequence of the placeholders obtained in the foregoing is divided according to the subset division rule, the obtained data subsets correspond to placeholder subsequences of P1 ═ { s1, s2, s1, s1, s3} and P2 ═ s3, s3, s3, s3, s4 }. The order of P1 precedes P2.
Thereafter, when the designated placeholder corresponding to the acquisition request is determined, the subset identifier of the target data subset corresponding to the acquisition instruction is page 2, and the designated placeholder corresponding to the subset identifier is each placeholder in the 2 nd placeholder subsequence P2 in the divided placeholder subsequences.
When the target data source corresponding to the designated placeholder is determined, the target data source corresponding to the placeholder can be determined in each data source according to the information corresponding to the data source in the designated placeholder. For example, the target data sources corresponding to the designated placeholders of the formed placeholder subsequence P2 are data source S3 and data source S4. The ordering of the target data subsets in each data subset is the order of the placeholder subsequence P2 corresponding to the target data subset in each placeholder subsequence. In the illustrative scenario of the present specification, the order of the target data subsets in each data subset is 2.
After the target data source corresponding to the designated placeholder is determined, a first offset and a second offset corresponding to the designated placeholder can be determined according to the arrangement condition of the data in the target data source in the data full set. The first offset and the second offset are used for determining a target data subset corresponding to the designated placeholder in each data corresponding to the data corpus contained in the target data source.
Procedure for determining target data subsets As shown in FIG. 3, when determining the first offset (Start) corresponding to each designated placeholder, all numbers before the sorting are determinedThe amount of data contained in the data subset that belongs to the target data source corresponding to the designated placeholder is used as the first offset of the designated placeholder. The placeholder subsequence P2 is preceded by a placeholder subsequence P1. The placeholder subsequence P1 includes 1 placeholder corresponding to the data source S3 and no placeholder corresponding to the data source S4. Then for each of the placeholder subsequences P2, corresponding to a placeholder S3 of the data source S3, the placeholder corresponds to a first offset of 1, i.e. Start S31 is ═ 1; corresponding to the placeholder S4 of the data source S4, the placeholder corresponds to a first offset of 0, i.e., StartS4＝0。
When a second offset (Count) corresponding to each designated placeholder is determined, determining an ordering of the designated placeholder in the placeholder subsequence as the second offset corresponding to the designated placeholder. The placeholder subsequence P2 includes 4 placeholders corresponding to the data source S3 and 1 placeholder corresponding to the data source S4. The second offset corresponding to each designated placeholder in the placeholder subsequence P2 is 1, 2, 3, 4, 1, i.e. CountS3,1＝1、CountS3,2＝2、CountS3,3＝3、CountS3,4＝4、 CountS4,1＝1。
And then, the server sends the first offset and the second offset to the corresponding target data source and receives the data corresponding to the acquisition request fed back by the target data source according to the first offset and the second offset. The target data source determines data corresponding to the acquisition request according to the first offset and the second offset, and may be implemented by the second process of sending data provided in the embodiments of the present specification.
Fig. 4 is a second process for sending data provided in the embodiment of this specification, which may specifically include the following steps:
s400: and receiving a data request sent by a server, wherein the data request comprises a full set identifier of a full set of data, a first offset and a second offset.
In particular, receiving a data request may be performed by a target data source to which the data request corresponds.
S402: and determining the data which is stored in the target data source and belongs to the data corpus according to the corpus identification.
For example, when the technical solution in this specification is applied to a case where a user selects a commodity through a terminal, for each target data source, data corresponding to the commodity is determined in the target data source from the commodity corresponding to the corpus identity as data corresponding to the data corpus in the target data source.
S404: and sequencing the determined data according to a preset sequencing rule aiming at the target data source.
The preset sort rule for the target data source may be configuration data loaded in the target data source, and a controller of the server may design the preset sort rule by changing the configuration data. For example, the preset ordering rule for the target data source may be: and ordering the data belonging to the data corpus in the target data source by taking the sales volume priority as a target.
S406: and determining data corresponding to the data request in the sorted data according to the sorted data, the first offset and the second offset.
For example, when the technical solution in this specification is applied to a user selecting a commodity through a terminal, if one of the target data sources is the data source S4, the first offset corresponding to the data source S4 is 0, and the second offset is 1. Thus, the data source S4 determines, as the data corresponding to the data request, the data whose order is the first order from among the sorted data.
S408: and returning the determined data corresponding to the data request to the server.
And after receiving the data corresponding to the acquisition request fed back by the target data source, the server sorts the data according to a preset sorting rule. The server can adjust the order of the data sent by the data source to the same order of the designated placeholders corresponding to the data in the placeholder subsequence P2 according to the ordering of the data fed back by the target data source. And the data with the arrangement sequence matched with the preset ordering rule after the ordering is the target data subset corresponding to the acquisition request. When the technical scheme in the specification is applied to a user selecting a commodity through a terminal, a target data subset corresponding to an acquisition request is data belonging to page 2 in a data corpus requested by the user through the terminal.

The embodiment of the present specification also proposes a schematic structural diagram of the electronic device shown in fig. 7. As shown in fig. 7, at the hardware level, the electronic device includes a processor, an internal bus, a network interface, a memory, and a non-volatile memory, but may also include hardware required for other services. The processor reads the corresponding computer program from the non-volatile memory into the memory and then runs the computer program to implement the process of sending data described in fig. 1 or fig. 4. Of course, besides the software implementation, the present specification does not exclude other implementations, such as logic devices or a combination of software and hardware, and the like, that is, the execution subject of the following processing flow is not limited to each logic unit, and may be hardware or logic devices.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory.
