Embodiment 1
[0155] Embodiment 1 of the present invention
[0156] The basic processing flow of a data transaction method, such as figure 1 shown, including the following steps:
[0157] Step 101, receiving a big data transaction request message;
[0158] Specifically, the data transaction device receives the big data sale request message sent by the data supplier device, and establishes a big data sale session mechanism; or the data transaction device receives the big data purchase request message sent by the data demander device, and establishes a big data purchase session mechanism; Or the data transaction device receives the big data proxy purchase request message sent by the data demander device, and establishes a big data proxy purchase session mechanism;
[0159] Wherein, the big data selling session mechanism, the big data buying session mechanism, and the big data purchasing agent session mechanism are all used to control the big data transaction process.
[0160] Step 102, per...
Embodiment 2
[0167] Taking a data transaction device receiving a big data purchase request message as an example, the detailed processing flow of a data transaction method in Embodiment 2 of the present invention is as follows: figure 2 shown, including the following steps:
[0168] Step 201, the data trading device acquires and stores the big data;
[0169] Specifically, the data transaction device receives the big data sale request message sent by the data supplier device through its own transaction portal navigation interface, establishes a big data sale session mechanism, and receives the big data.
[0170] Step 202, the data transaction device processes the big data;
[0171] Specifically, the data transaction device performs data extraction and primary processing on the big data to obtain primary processing data; performs preparatory processing on the primary processing data to obtain pre-processing data; analyzes and processes the pre-processing data to obtain analysis Processing...
Embodiment 3
[0185] Taking a data transaction device receiving a big data sale request message as an example, the detailed processing flow of a data transaction method in Embodiment 3 of the present invention is as follows: image 3 shown, including the following steps:
[0186] Step 301, the data transaction device receives a big data sale request message;
[0187] Specifically, the data transaction device receives the big data sale request message sent by the data supplier device, and establishes a big data sale session mechanism;
[0188] Wherein, the big data sale request message carries the data descriptor, data identifier, data type, data volume, data quality, frequency of use, duration of use, number of authorized users, copyright information, rate, right It belongs to transaction negotiation parameters such as transfer attribute and transaction agreement; the big data selling session mechanism is used to control the big data transaction process.
[0189] In step 302, the data tra...
