Adopt the concrete operations flow process of method and system of the present invention can consult Fig. 1 and Fig. 2, comprise the steps:
The first step
At first, the information publisher submits to super node with the index information of commodity.The realization of this process is finished by information input system, can be with reference to figure 3.
The information publisher imports the information relevant with commodity by being installed in the software systems on the user endpoints, for example for dress, can import its descriptors such as color, size and pattern.User's input can be carried out according to predefined template, also can be by the attribute of user oneself definition commodity.After the user finished the information input, user side software generated index information and two parts of details according to the information of user's input.
Index information is one section description at the main feature of commodity, and it can be generated by the template that pre-defines, and also can comprise user-defined attribute and description thereof.Details are meant the data that commodity are described in detail, and for example one section illustrative words, picture, animation (for example Flash, Video etc.) or other users are to evaluation of this commodity etc.
For example, the user need sell an in men's style jacket, and the index information of these part commodity can be defined as " man style, jacket, last dress, black, 170 (sizes) " so; The details of these part commodity can comprise following content: the brand of this jacket that is described with literal, pattern, size, materials are done manual work and information such as price, the picture of these jacket all angles, this jacket of showing with animation or video mode is through model or virtual portrait effect on one's body, and businessman or other users are to the network address of the comment of these type of commodity and link etc.
After index information and details generated, details were stored in the local information storage system; Index information is sent to super node end software.
Second step
Consult Fig. 4, after index information is submitted to super node, the commodity index information is carried out preliminary audit survey by the signal auditing system of super node end.The signal auditing system can comprise following examination content: whether the commodity index information that the user submits to is legal, whether the commodity index information is fit to issue, whether the commodity index information repeats etc.
The commodity index information is just submitted to information storage system by after examining.
The 3rd step
Information storage system is added the commodity index information in the existing database to, notes the identification information of the user node of submitting this commodity index information to simultaneously, and sets up related between commodity index information and the user node identification information.
Information storage system is made up of a background data base, by this database, information and other relevant informations that the information publisher submits to can be left in the database, described database is a general reference notion, represents the relevant database of various forms, and is not limited to the database of certain specific format, can select business database such as DB2 for use, Qracle, SQL Server etc. also can select free database MySQL etc.
The user node identification information is meant the necessary information that is used for unique differentiation different user node, and it can comprise user's login ID, the contents such as IP address of user node.
In this example, after the user had issued and sold the information of the in men's style jacket of black, the index information that just can set up the in men's style jacket of this part black in information storage system was with the contact between the online client who comprises these jacket details.For retrieving conveniently, the commodity index information can be mapped as a cryptographic Hash, hash algorithm can adopt existing ripe algorithm such as SHA-1, MD5, Digital Signature Algorithm etc., but be not limited to listed algorithm.Can release news to the user like this and carry out digital signature, the authenticity and the uniqueness in guarantee information source, and the safety of guarantee information transmission.For example:
Cryptographic Hash (the in men's style jacket index information of black) ← → IP address 1 (online client 1 that comprises these jacket details)
Cryptographic Hash (the in men's style jacket index information of black) ← → IP address 2 (online client 2 that comprises these jacket details)
The 4th step
When the user need retrieve merchandise news, directly in user node software, import the desired commodity feature of user.These features can be the characteristics (for example color of clothes) that commodity itself are had, and can also be some statistical informations (such as popular, the most most popular commodity etc.) at commodity.The user finishes after the input, and the information that user node software is submitted the user to is converted into the search condition of specific format, sends to power user's node software then.
The 5th step
Power user's node software response user's searching request is accepted the search condition that search subscriber is submitted to, retrieves then.This system is a searching system based on database, and the mode of its realization can be a lot.We can use ODBC and JSP, PHP, and the mode that language such as ASP combine realizes retrieval, also can develop corresponding software and support this retrieval.
After searching system receives the search condition that search subscriber submits to, can in searching database, find all information that are complementary with search condition, these information be exactly the commodity index information and with its clients corresponding identification information.
The commodity index information that comprises in the Search Results is meant the description about the commodity feature that the client submitted to by issue merchandise news.User node identification information in the Search Results is meant the user ID of client or IP address etc., is storing the details of the commodity that the user retrieves on these online user's nodes.
After Search Results generated, power user's node software returned to this Search Results the user node that sends searching request.
The 6th step
User node software receives the Search Results that returns from super node, after Search Results being carried out the merger arrangement, the commodity index information is presented in face of the user.The user browses the index information of commodity, can further submit the request of browsing the commodity details to according to oneself hobby and needs then.
User node software receives the request that the user browses the commodity details, asks the details of commodity to other online users that comprise these commodity details.After receiving complete commodity details, user node software deposits commodity details and commodity index information in local cache simultaneously.The realization of this process can be with reference to figure 5.
In this example, if user entered keyword " jacket " is retrieved, what at first see may be following commodity index information tabulation:
The in men's style jacket of black
Yellow jacket (woman style)
Leather jacket
Next, if the user is comparatively interested in " the in men's style jacket of black ", can require to obtain more detailed description.At this moment, user node software will comprise the in men's style jacket details of this black simultaneously in previous example user node IP address 1 and IP address 2 send request, require to obtain the details of the in men's style jacket of this black.
The 7th step
User node software to the commodity details that receive analyze, comprehensive and arrangement, the condition of setting according to the user shows final detailed merchandise news then.
The 8th step
Each user node all has its specific unique identifier (user name), the user can and issue merchandise news person by getting in touch with based on the instant communication software of P2P technology by this unique identifier when browsing merchandise news, carry out real-time communication by quick means such as text, voice or video and online publisher.
