detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Fig. 1 is a flow chart of a financial data processing method provided by Embodiment 1 of the present invention. As shown in Fig. 1, the method of this embodiment may include:

Step 101. Receive the financial data request sent by the application software, and forward the financial data request to the source data server. The financial data request includes the application software identification.

Specifically, this embodiment provides a data exchange component, the data exchange component is connected with different application software such as stock market software, futures market software, and foreign exchange market software, and at the same time, the data exchange component is connected with a source data server that stores financial data . Different application software such as stock quotation software, futures quotation software, and foreign exchange quotation software can send financial data requests to the data exchange component, and the financial data requests include application software identifiers.

Step 102, receiving the financial data obtained by the source data server according to the financial data request.

Specifically, the data exchange component converts the financial data request into a financial data request conforming to the communication protocol of the source data server, and then sends the financial data request after the protocol conversion to the source data server. Preferably, the data description language Protocol Buffers can be used to develop the communication protocol of the source data server. The source data server sends the financial data to the data exchange component according to the received financial data request. The data exchange component receives the financial data returned by the source data server.

Step 103, according to the correspondence between the pre-stored application software identification and the data format type supported by the application software, determine the data format type corresponding to the application software identification;

Convert the financial data according to the data format type, and send the converted financial data to the application software, so that the application software can display the visual data.

Specifically, the data exchange component pre-stores the data format types supported by different application software. Since different application software has different application software identifiers, the corresponding relationship between the application software identifier and the data format types supported by the application software can be established. Therefore, the data exchange component can search for the data format type corresponding to the application software identifier. Then, the data exchange component converts the format of the financial data, and then sends the financial data after the format conversion to the application software, so that the application software can receive the financial data that can be identified, and then use the financial data to draw tables or change curves, so as to transfer the financial data to the application software. The data is displayed to the user in the form of visual data.

In this embodiment, the financial data obtained from the source data server is format-converted according to the correspondence between the pre-stored application software identification and the data format type supported by the application software, so that the financial data becomes the data format type supported by the application software. In this way, it is convenient for the application software to read and process the acquired financial data in a timely manner, and to display the financial data visually to the user in a timely manner.

Fig. 2 is a flowchart of another financial data processing method provided by Embodiment 2 of the present invention. As shown in Fig. 2, the method of this embodiment may include:

Step 201: Receive financial data requests sent by different application software; convert the financial data requests sent by different application software into preset formats; forward each financial data request converted into preset formats to the source data server.

Specifically, this embodiment provides a data exchange component, which is provided with receiving interfaces connected to different application software, and the data exchange component receives financial data requests from different application software through these receiving interfaces, and each financial data request Contains the identification of each application software. Since the development languages and development environments of different application software are different, the data exchange components have different voice environment receiving interfaces to match the application software; for example, the data display service software uses a scripting language for Compiled, so that the receiving interface corresponding to the data exchange component and the data display service software can use C++ language to call commands in the data display service software.

After the data exchange component receives the financial data requests sent by different application software, since the data types of the financial data requests from different application software are different, in order to facilitate the transmission of these financial data requests inside the data exchange component, it is necessary to The financial data requests sent by different application software are respectively converted into the preset formats supported by the data exchange component. For example, the format conversion corresponding to the mapping relationship of the source data server can be performed on the financial data requests. Then, each financial data request converted into a preset format is converted into a financial data request conforming to the communication protocol of the source data server, and then forwarded to the source data server respectively.

Step 202, receiving the financial data obtained by the source data server according to the financial data request.

Specifically, the data exchange component sends the financial data request to the source data server. Before sending the financial data request each time, the financial data request packet is disassembled into a leading data request packet and a data follow-up request packet. The leading data request packet includes The size of the data follow-up request package, which includes the type of financial data, the business identification of financial data, the time of financial data, and the identification of application software in the data follow-up request package; first, send the leading data request package to the source data server, so that the source data server According to the size of the data follow-up request package in the leading data request package, prepare space for receiving the data follow-up request package; then send the data follow-up request package to the source data server, so that the source data server queries the financial data corresponding to the data follow-up request package . The source data server finds the financial data corresponding to the financial data request in the database and returns it to the data exchange component, and the data exchange component receives the returned financial data.

At the same time, in this process, a connection-oriented TCP transmission protocol is established between the data exchange component and the source data server to ensure reliable data transmission. Specifically, the data exchange component provides a communication interface and establishes a socket link with the source data server. Based on this method, the data exchange component sends a financial data request to the source data server, and at the same time, the data exchange component receives the financial data returned by the source data server . In this embodiment, a Boost ASIO library may be used to establish a communication interface.

Step 203, the financial data includes a data size field, which describes the size of the financial data; according to the data size field, check whether the financial data is complete.

Specifically, since the types of financial data received by the data exchange component are different, the size of the financial data packets is also different. In order to ensure the integrity of the received financial data, it is necessary to design relevant mechanisms to verify the integrity of the data. The financial data received by the data exchange component includes a data size field, which indicates the size of the financial data; it can be checked whether the data packet of the financial data is complete according to the data size field. For example, in the process of sending financial data, due to objective reasons such as the network environment, one-time financial data reception may be incomplete. First, the data exchange component will receive the data size field of the financial data, and continuously check it according to the data size field The size of the data packet of the received financial data, until the size of the data packet of the received financial data is consistent with the size of the data size field, a verification is stopped, and at the same time, it indicates that the receiving work of the current financial data is completed.

Step 204, if the result of checking the financial data in step 203 is complete, then determine the data format type corresponding to the application software identification according to the correspondence between the pre-stored application software identification and the data format type supported by the application software; The format type performs format conversion on the financial data, and sends the converted financial data to the application software, so that the application software can display the visual data.

Specifically, if the received financial data is complete, first analyze the financial data. Then, according to the corresponding relationship between the application software identifier and the data format types supported by the application software, the analyzed financial data is converted into a data format type that meets the requirements of the application software.

For example, some quotation table data, market time data, which are stored in the source data server as integer data, but the application software that requests the data uses the string format, then after finding the corresponding relationship, convert the data into characters string data. Some trading suspension data is in the string format in the source data server, but the application software requesting the data is in the Boolean format. After finding the corresponding relationship, convert the data into Boolean format data. For another example, the format of some financial data needs to be rearranged. The stock code list data in the source data server is stored in the format of stock code first, name abbreviation after, and the format used by the application software requesting the data is name abbreviation First, the securities code is second, you need to find the corresponding relationship, and then rearrange the information in the data. For another example, it is necessary to identify or add fields to the format of some financial data. The market to which the stock belongs in the real-time quotation data is identified by an integer number in the source data server. "0" represents Shenzhen Stock Exchange, and "1" represents Shanghai stock market, etc.; and the application software that requests the data uses Chinese characters to identify the market to which the stock belongs, and needs to convert the identification method of the market to which the stock belongs in the real-time market quotation data into Chinese characters after finding the corresponding relationship. For another example, some financial data does not have record sequence information set in the source data server. These record sequence information includes transaction by transaction, transaction by month, etc., and the application software that requests the data needs to record sequence information. After searching for the corresponding relationship, Add this data to record sequence information. For another example, stock code data includes stock code and stock type. The stock code and stock type are saved in a field in the source data server, and the data storage format used by the application software requesting the data is that the stock code and stock type are It is stored in two fields. After finding the corresponding relationship, the stock code and stock type in the stock code data need to be disassembled into two fields. For example, in the source data server, the stock code and stock type are "123456.32 ", where 123456 is the stock code, and 32 is the stock type, and "123456.32" needs to be disassembled into two separate fields for storage according to the requirements of the application software.

This embodiment converts the financial data requests sent by different application software into preset formats, thereby facilitating the delivery and processing of financial data requests; at the same time, according to the data size field in the financial data, the integrity of the financial data is verified, thereby ensuring The integrity of the financial data received from the source data server is guaranteed.

Further, on the basis of the above-mentioned embodiments, in step 201, each financial data request converted into a preset format is forwarded to the source data server respectively. The specific implementation method may be:

Put each financial data request converted into a preset format into the queue in turn;

Each financial data request in the queue is sequentially forwarded to the source data server in a preset order.

Specifically, since different application software will initiate financial data requests at the same time, and the same application software will initiate multiple financial data requests, it is necessary to set up a message loop queue mechanism to maintain the source data server where these requests can be sent, and at the same time protect the data There is no blocking inside the switching component. A queue is provided, and each financial data request converted into a preset format is sequentially put into the queue. Preferably, the data type of the queue is an associated container type. According to the preset order, each financial data request in the queue is sequentially taken out, and then the financial data request is converted into a financial data request conforming to the communication protocol of the source data server and then sent to the source data server.

Wherein, the preset order includes an order determined according to at least one of the following indicators: priority of application software, time of storing in queue, and size of financial data request.

Specifically, the preset order can use indicators such as application software priority, time stored in the queue, and size of financial data requests to determine the order in which financial data requests are taken out of the queue. Specifically, the method of software priority is that the priority level is set for each application software, and the financial data request sent by the application software with higher priority in the queue can be taken out first. Specifically, the time method of storing in the queue is that according to the time sequence of storing in the queue, the financial data requests stored in the queue are taken out first, and then the financial data requests stored in the queue are taken out later. Specifically, the size of the financial data request is as follows: the financial data request with the smaller data packet in the queue is taken out first, and then the financial data request with the larger data packet in the queue is taken out.

In this embodiment, each financial data request converted into a preset format is put into the queue in turn, and then each request in the queue is sequentially taken out according to the preset sequence such as the priority of the application software, the time of storing in the queue, and the size of the financial data request. Financial data request. This ensures that different financial data requests from various application software can be effectively sent to the source data server, without data loss or data transmission failure, and at the same time, it will not cause blockage in message transmission.
