Hardware-software complex of electronic sales system; data exchange method in it

The invention relates to the financial field and can be used to organize sales and auctions using a real-time communication network.

Electronic trading platforms zakupki.gov.ru, sberbank-ast.ru, etp.zakazrf.ru and many others are known (the list is known from the resource http://aetp.ru/etp/list), which are used both by private commercial organizations and for the organization of public procurement, which provide a search of the archived database of procedures, as well as current procedures.

From the resource http://www.norbit.ru/products/913.html there is an electronic trading platform in the form of a website on which information about goods, as well as information on procurement, is posted. The platform uses an Electronic Digital Signature, actions with it are legally significant. Also, the site has the ability to integrate with the enterprise information system.

US 7702540 discloses a method and equipment for an electronic trading system, including a first data storage location for storing information about an auction item from a first participant in a packet data network, a verification process that verifies the user identification of the first participant in a packet data network, verification process , which confirms the identification of the first participant, before allowing the participant in a particular session access to the packet data network to post info information about the item to be auctioned in the system, the display process for displaying information about the auction lot for many users of the packet data network, the display process showing ads along with the auction lot with many users of the packet data network, the auction process for receiving applications for auction lots from at least one of said plurality of users of a packet data network, an auction process that also verifies the identity of a user from said plurality of users firs packet data network before allowing the call and notification process for notifying the plurality of members of the network packet data, that this rate has been accepted by said system.

From the patent application US 20140229334, a network sales system is known that provides a search on the base of products and provides a payment format per lot. The system consists of several modules, namely, a database module, a product list display module, a transaction support module, a feedback module, and a party interaction module.

From patent No. 2174708 RU, a method of trading for cashless payments using a communication network is known, which includes placing on the seller’s computer device a list of the offered goods (works, services), indicating account details for paying for these goods, the details of the allocated account being indicated as the account at a transit bank, viewing the specified list by the buyer, assigning an individual code for each payment, paying for the goods by making a payment to a dedicated account, additional message in transit the bank assigned to pay the cipher, providing the buyer with the goods (work, services) provided the buyer informs the cipher of the cipher by the buyer, informing the transit bank of the cipher received from the buyer, transferring money to the seller in the amount of the specified payment, provided that the cipher communicated by the seller to the transit bank matches the cipher received by the transit bank in addition to the specified payment.

From patent No. 2222826 RU there is an interactive system and method for concluding transactions intended for interactive conclusion of transactions between a plurality of buyers and a plurality of sellers. The invention operates in an advanced extranet system, which is a secure system with limited access, operating as part of a large packet switched public network (Internet), and provides access to the site only to registered buyers and sellers. Moreover, the extranet system is connected with existing credit systems, a clearing house, insurance, transport, road and banking systems and uses their capabilities. The online database includes real-time information related to the transaction when a customer submits a request for a product, and this request blocks the requested product from being selected by any other customers. Buyer information and purchase data are sent to the settlement system, which either approves or rejects the request based on the customer’s existing characteristics and credit information. If the clearing house approves the request, the shipper, buyer and / or seller are notified. If the clearing house rejects the request, then the requested product is exempted. Notification of the shipper, buyer and / or seller includes determining the terms of export and delivery for the shipper, notifying the buyer of the receipt of the request and determining the conditions for the purchase, delivery of the product to the buyer, creating a confirmation document for delivery and sending the delivery confirmation to the financial institution receiving payment from the financial institution and ultimately, the distribution of payment in at least one of the online databases, clearing house and seller.

From patent No. 2285293 RU, an automated system for concluding transactions between borrowers and holders of savings and a method for conducting an auction using this system are known. The system receives an electronic offer of a savings deposit and a seller’s rate from an organization representing the owner of the savings. Electronic funds managed by a financial auctioneer sort, collate and select electronic offers of savings deposits and requested rates of the seller, which match the electronic loan applications and the proposed rates of the buyer. And then they form a lot of pairs of matching offers of the seller and the buyer or transactions, calculate the transaction at the expiration of the loan and make it available to organizations representing borrowers that do not require the creation of a reserve fund through a sterilization account during the loan term. In addition to buyers and sellers, the clearing company also takes part in the auction as an observer. The borrower participates in the system subject to the opening of a deposit account.

From patent No. 2372657 RU, a system and method for conducting an online auction are known. A server for conducting an online auction, connected to the computers of participants through a communication network through a server-client relationship, and continuously repeating an auction for the same product so that the server opens a new auction after the auction for the same product is completed. The server also contains an auction database, a means for repeating the auction for other buyers of the same product with the inclusion of the flag of the auction database after recording the proposal of the first bidder, and an auction tool for the same product, including:

- a means to determine if there is an auction open for a particular product;

- a means to create a new auction for an item if there is no auction open for the item;

- a means of receiving a request from the participant’s computer to review the existing price for this product,

- a means to reduce the existing price of the goods by the amount of the revision of the existing price, when the participant of the created auction requests the server to revise the existing price through the participant’s computer, a means of recalling the amount of the revision of the existing price from the money provider and recording feedback regarding the money provider, due to which the existing price of the goods continuously falls upon a request of participants to review the existing price transferred from participants' computers,

- a means for determining the first bidder at a specific existing price as the winner by searching for the auction flag in the auction database, displaying the winner in the winner’s computer, determining the existing price as the winning price, closing the existing auction with the auction flag turned off in the auction database,

- a means of recording the offer of the first bidder who lost in the previous auction of the same product to repeat the auction for other buyers of the same product after recording the offer of the first bidder.

The aim of the invention is to increase the availability of bidding objects, as well as bidding procedures, while ensuring security regarding errors in the exchange of information between elements of the sales system in the sense of errors in data transmission.

The goal is achieved due to the fact that the hardware-software complex is divided into layers, the top one being a remote server with the user interface program located in its memory, the middle one is the central server of the auction organizer with the database of the auction objects located in its memory, as well as the accounting system objects, for example 1C, and the bottom layer is a local communication network with computers of bidding operators. In this case, the layers exchange information through a global network and are separated by firewalls. The exchange of information between the layers of the hardware-software complex is organized in the following order:

1. Organize the exchange of certificates of increased cryptographic strength for authorization and identification between the operating systems of the layers.

2. On all servers of the complex, a local directory is allocated for the synchronization procedure (on all servers of heterogeneous systems involved in the exchange)

3. A mechanism is being prepared to periodically launch the data exchange subsystem (as a rule, this is the system scheduler of the operating system)

4. For each system, a unique postfix is defined for the name of the local directory.

5. On all servers, two subdirectories are allocated for each system with the prefixes “to” and “from”.

6. Create an exchange subsystem and organize its work in accordance with the following algorithm:

Копируют данные с сервера первой системы из папки to_ПерваяСистема в папку to_ПерваяСистема на сервере второй системы

Copy data from the server of the first system from the folder to_FirstSystem to the folder to_FirstSystem on the server of the second system

Удаляют из from_ПерваяСистема на сервере второй системы файлы, которые существуют в from_ПерваяСистема на сервере первой системы

From files from_FirstSystem on the server of the second system, delete files that exist in from_FirstSystem on the server of the first system

Зеркалируют данные из from_ПерваяСистема на сервере второй системы в from_ПерваяСистема на сервере первой системы.

Mirror data from from_FirstSystem on the server of the second system to from_FirstSystem on the server of the first system.

Повторение процедуры обмена данными для поддиректорий to_ВтораяСистема и from_ВтораяСистема.

Repeating the data exchange procedure for the subdirectories to_SecondSystem and from_SecondSystem.

В первой и второй системе создают подсистемы обработки данных, которые берут данные из папки «from …» и после обработки копируют эти данные в папку «to …».

The first and second systems create data processing subsystems that take data from the “from ...” folder and after processing copy this data to the “to ...” folder.

By ensuring the connection of the database of the bidder and the communication networks of bidders through an interface that combines the heterogeneous systems of these two entities, a wide coverage of bidders, ease of access, and the speed of providing information about the bidding objects is achieved. Moreover, due to the exchange of certificates, as well as duplication of information during data exchange, a low level of errors in data transmission is achieved, which is important when organizing a commodity-money exchange. For the same purpose, firewalls are used, which, as a tool for organizing and regulating the exchange of data between network entities, provide control over the interface in terms of data exchange between heterogeneous layer systems. As a result, the number of errors during data exchange is reduced, the operating time is reduced, since errors are detected at the stage of query generation.
