Description

Technical Field

[0001] The present invention relates to the field of distributed technology, and in particular to a multi-level account linkage system and method across new and old systems. Background Art

[0002] In large-scale systems, high-performance national services with large business volumes are provided. In large-scale systems, new systems have been developed and need to be switched part by part for safety reasons. Since the switching period may be long (such as 1-2 years), any transaction must not only consider the processing of a single old system or a single new system (distributed), but also consider transactions across the old and new systems. Since the account that triggers multi-level linkage is not within the transaction elements, there is a problem that it cannot be pre-routed. In addition, the linked accounts may exist in the new and old systems. If the system is a host system, it may not be allowed to be transferred externally due to transaction security considerations. Multi-level linkage is limited by the account's own balance, transfer balance, and linkage conditions, so it can only be linked in sequence. Therefore, there is currently a lack of a multi-level linkage method for accounts across the old and new systems. Summary of the invention

[0003] The embodiment of the present invention proposes a multi-level linkage system for accounts across new and old systems, which is used to realize multi-level linkage of accounts across new and old systems. The system includes:

[0004] Multiple linkage nodes, where each linkage node corresponds to a new system or an old system;

[0005] Linkage nodes are used to:

[0006] Receiving a transaction success message of the current account sent by a corresponding system, the system being a new system or an old system;

[0008] Generate atomic transactions corresponding to the current account and atomic transactions corresponding to the linked account;

[0009] Send the atomic transaction corresponding to the current account to the corresponding system;

[0010] Send the atomic transaction corresponding to the linked account to the linked node corresponding to the system corresponding to the linked account;

[0011] After receiving the transaction success message of the atomic transaction corresponding to the current account returned by the corresponding system, the transaction success message of the atomic transaction corresponding to the current account is sent to the linkage node corresponding to the system corresponding to the linked account; the linkage node corresponding to the system corresponding to the linked account returns the linkage result according to the transaction result of the atomic transaction corresponding to the linked account and the transaction success message of the atomic transaction corresponding to the current account;

[0012] Receive the linkage result returned by the linkage node corresponding to the system corresponding to the linked account.

[0013] The embodiment of the present invention proposes a method for multi-level linkage of accounts across new and old systems, which is applied to the aforementioned system to achieve multi-level linkage of accounts across new and old systems. The method includes:

[0014] Receiving a transaction success message of the current account sent by a corresponding system, the system being a new system or an old system;

[0016] Generate atomic transactions corresponding to the current account and atomic transactions corresponding to the linked account;

[0017] Send the atomic transaction corresponding to the current account to the corresponding system;

[0018] Send the atomic transaction corresponding to the linked account to the linked node corresponding to the system corresponding to the linked account;

[0019] After receiving the transaction success message of the atomic transaction corresponding to the current account returned by the corresponding system, the transaction success message of the atomic transaction corresponding to the current account is sent to the linkage node corresponding to the system corresponding to the linked account; the linkage node corresponding to the system corresponding to the linked account returns the linkage result according to the transaction result of the atomic transaction corresponding to the linked account and the transaction success message of the atomic transaction corresponding to the current account;

[0030] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

Moreover, the specific features, structures or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. The order of steps involved in each embodiment is used to schematically illustrate the implementation of the present application, and the order of steps is not limited and can be appropriately adjusted as needed.

[0032] Figure 1 FIG. 1 is a schematic diagram of a multi-level linkage system for accounts across new and old systems in an embodiment of the present invention. Figure 1 As shown, the system includes:

[0033] Multiple linkage nodes, where each linkage node corresponds to a new system or an old system;

[0034] Linkage nodes are used to:

[0035] Receiving a transaction success message of the current account sent by a corresponding system, the system being a new system or an old system;

[0036] Query the linkage parameter table to determine whether the current account meets the trigger conditions. If so, read the linkage parameter table of the corresponding system to obtain the linked account;

[0037] Generate atomic transactions corresponding to the current account and atomic transactions corresponding to the linked account;

[0038] Send the atomic transaction corresponding to the current account to the corresponding system;

[0039] Send the atomic transaction corresponding to the linked account to the linked node corresponding to the system corresponding to the linked account;

[0040] After receiving the transaction success message of the atomic transaction corresponding to the current account returned by the corresponding system, the transaction success message of the atomic transaction corresponding to the current account is sent to the linkage node corresponding to the system corresponding to the linked account; the linkage node corresponding to the system corresponding to the linked account returns the linkage result according to the transaction result of the atomic transaction corresponding to the linked account and the transaction success message of the atomic transaction corresponding to the current account;

[0041] Receive the linkage result returned by the linkage node corresponding to the system corresponding to the linked account.

[0042] In the embodiment of the present invention, the multi-level linkage does not require cross-system account synchronization and does not affect the performance of the original system and original account operations.

[0043] In specific implementation, multi-level account linkage means that in some large enterprises, there will be multi-level institutions and corresponding multi-level accounts managed by the enterprise. In order to achieve account balance management, a multi-level account balance linkage mechanism will be used in the bank, such as 4-level linkage. A<-B<-C<-D. For example, when the balance of account D exceeds a certain upper limit, the balance will be transferred to C according to certain rules, and the same mechanism will be used for accounts C and B. In this way, a transaction may implicitly trigger an account linkage operation that is not easily perceived by the user.

[0044] Table 1 is an example of a linkage parameter table.

[0045] Table 1

[0046]

[0047] In specific implementation, each linkage node corresponds to a new system or an old system. The new systems or old systems do not communicate with each other, but through the linkage node. The new system or the old system conducts transactions normally. Each time a transaction is successful, a transaction success message is sent to the corresponding linkage node.

[0048] In one embodiment, the transaction success message is sent through a message queue. The message queue is a one-way asynchronous operation, which avoids the host external call operation of the new system or the old system. In the high-performance operation of the host, it will not cause performance bottlenecks for existing transactions. When the message queue is unblocked, its connection speed will be very fast.

[0049] In addition, in the old and new systems of the bank, multi-level linkage accounts account for a small proportion, so the transformation of the main logic of the old and new systems will cause the performance of other transactions to decline. Therefore, the embodiment of the present invention proposes a multi-level linkage system for accounts across the old and new systems, which is independent of the existing old and new systems. The multi-level linkage account processing logic is relatively centralized, which can improve processing efficiency.

[0050] Multiple linkage nodes can form a P2P sub-network for a small amount of complex internal interactions. Each linkage node can be served by an internal interaction module attached to the new system or the old system. This does not increase the hardware complexity of the original system, and the P2P sub-network has the fastest point-to-point network interaction speed. Although it seems complicated, in fact, if there are N systems, each node only has N-1 connections to manage.

[0051] It should be pointed out that each new system or old system only operates the linkage between the account of the system and the next account. Since the transfer operation of the two accounts requires transaction consistency, it must be completed on the same initiator, but the linkage operation of the next account is moved to the system to which the next account belongs. The advantage of this is that each account and its linkage parameters do not need to be copied and synchronized across systems, as long as they are saved locally. It provides convenience for the division of accounts and their linkage parameters by system and region.

[0052] In one embodiment, the linkage node is specifically used for:

[0053] Send the received atomic transaction corresponding to the linked account to the corresponding system;

[0054] After receiving the transaction success message of the atomic transaction corresponding to the linked account returned by the corresponding system, read the linkage parameter table of the corresponding system to determine whether the linked account meets the triggering conditions;

[0055] If the linked account meets the triggering conditions, wait for the transaction success message of the atomic transaction corresponding to the current account;

[0056] When receiving the transaction success message of the atomic transaction corresponding to the current account, read the linkage parameter table of the corresponding system to obtain the linked account of the corresponding system;

[0057] When the transaction success message of the atomic transaction corresponding to the current account times out, the linkage result is determined to be a linkage failure message, and sent to the linkage node corresponding to the system corresponding to the current account;

[0058] If the linked account does not meet the triggering condition, the linkage result is determined as a linkage success message, and sent to the linkage node corresponding to the system corresponding to the current account.

[0059] In the above embodiment, when the transaction success message of the atomic transaction corresponding to the current account is received, the linkage parameter table of the corresponding system is read to obtain the linked account of the corresponding system, so that the multi-level account linkage can continue according to the aforementioned method, and regardless of whether the linkage succeeds or fails, the linkage result will be sent to the previous linkage node, so the linkage result will be gathered to the first linkage node.

[0060] In one embodiment, the linkage node is further used for:

[0061] After receiving the transaction success message of the atomic transaction corresponding to the current account returned by the corresponding system, record the linkage operation log;

[0062] After receiving the linkage result, record the linkage operation log.

[0063] In the above embodiment, the first linkage node will record the linkage operation log for subsequent review and verification.

[0064] In one embodiment, the linkage node is further used for:

[0065] When there are multiple atomic transactions corresponding to the current account and the linked account, the atomic transaction corresponding to the current account is sent to the corresponding system according to the transaction order, and the atomic transaction corresponding to the linked account is sent to the linkage node corresponding to the system corresponding to the linked account.

[0066] A specific embodiment is given below to illustrate the specific application of the system proposed in the embodiment of the present invention.

[0067] Figure 2 It is a specific application schematic diagram of the multi-level linkage system for accounts across the old and new systems in an embodiment of the present invention. The multi-level linkage system for accounts across the old and new systems includes four linkage nodes 1, namely linkage node 1, linkage node 2, linkage node 3, and linkage node 4, which correspond to the systems of four banks, namely old system 1, new system 2, new system 3, and new system 4.

[0068] Linkage node 1 receives the transaction success message of account 1 sent by old system 1, queries linkage parameter table 1, determines that account 1 meets the trigger condition, reads linkage parameter table 1 corresponding to system 1, and obtains linked account 2; generates atomic transaction corresponding to account 1 and atomic transaction corresponding to linked account 2; sends the atomic transaction corresponding to account 1 to old system 1; sends the atomic transaction corresponding to linked account 2 to linkage node 2 corresponding to new system 2 corresponding to linked account 2; after receiving the transaction success message of the atomic transaction corresponding to account 1 returned by old system 1, sends the transaction success message of the atomic transaction corresponding to account 1 to linkage node 2; receives linkage result 1.

[0069] Linkage node 2 sends the received atomic transaction corresponding to linked account 2 to new system 2; after receiving the transaction success message of the atomic transaction corresponding to the linked account returned by new system 2, linkage node 2 reads linkage parameter table 2 of new system 2 to determine whether linked account 2 meets the triggering condition;

[0070] If the linked account 2 meets the triggering conditions, wait for the transaction success message of the atomic transaction corresponding to account 1;

[0071] When receiving the transaction success message of the atomic transaction corresponding to account 1, read the linkage parameter table 2 of the new system 2, obtain the linked account 3 of the new system 2, and then continue to link the linked account 2 and the linked account 3 to obtain the linkage result 2;

[0072] When the transaction success message of the atomic transaction corresponding to account 1 times out, linkage result 1 is determined to be a linkage failure message, and is sent to linkage node 1 corresponding to old system 1 corresponding to account 1;

[0073] If the linked account 2 does not meet the trigger condition, the linkage result 1 is determined to be a linkage success message, and is sent to the linkage node 1 corresponding to the old system 1 corresponding to the account 1.

[0074] Linkage node 1 records the linkage operation log according to linkage result 1 and the transaction success message of the atomic transaction corresponding to account 1.

[0075] In summary, in the system proposed in the embodiment of the present invention, each linkage node corresponds to a new system or an old system; the linkage node is used to: receive a transaction success message of the current account sent by the corresponding system, the system being the new system or the old system; query the linkage parameter table to determine whether the current account meets the trigger condition, if so, read the linkage parameter table of the corresponding system to obtain the linked account; generate the atomic transaction corresponding to the current account and the atomic transaction corresponding to the linked account; send the atomic transaction corresponding to the current account to the corresponding system; send the atomic transaction corresponding to the linked account to the linkage node corresponding to the system corresponding to the linked account; after receiving the transaction success message of the atomic transaction corresponding to the current account returned by the corresponding system, send the transaction success message of the atomic transaction corresponding to the current account to the linkage node corresponding to the system corresponding to the linked account; the linkage node corresponding to the system corresponding to the linked account returns the linkage result according to the transaction result of the atomic transaction corresponding to the linked account and the transaction success message of the atomic transaction corresponding to the current account. In the above process, multi-level linkage does not require cross-system synchronization of accounts, and does not affect the performance of the original system's original account operations. In addition, the transfer out of an account and the transfer in of another account can easily achieve consistency of things due to the single point control. If a certain linkage link fails, the successful linkage operation is complete. The connectivity of the P2P network composed of multiple linkage nodes is actually not complicated and has good performance. Finally, a complete multi-level linkage operation status is provided, which is convenient for subsequent reference and troubleshooting.

[0076] The embodiment of the present invention further proposes a method for multi-level linkage of accounts across new and old systems, the principle of which is similar to the multi-level linkage system of accounts across new and old systems, and will not be described in detail here.

[0091] Step 4022: If the linked account does not meet the trigger condition, the linkage result is determined as a linkage success message, and sent to the linkage node corresponding to the system corresponding to the current account.

[0092] In one embodiment, sending the atomic transaction corresponding to the current account to the corresponding system, and sending the atomic transaction corresponding to the linked account to the linkage node corresponding to the system corresponding to the linked account, includes:

[0093] When there are multiple atomic transactions corresponding to the current account and the linked account, the atomic transaction corresponding to the current account is sent to the corresponding system according to the transaction order, and the atomic transaction corresponding to the linked account is sent to the linkage node corresponding to the system corresponding to the linked account.

[0094] In one embodiment, the method further comprises:

[0095] After receiving the transaction success message of the atomic transaction corresponding to the current account returned by the corresponding system, record the linkage operation log;

[0097] In summary, in the method proposed in the embodiment of the present invention, a transaction success message of the current account sent by the corresponding system is received, and the system is a new system or an old system; the linkage parameter table is queried to determine whether the current account meets the trigger condition, and if so, the linkage parameter table of the corresponding system is read to obtain the linked account; the atomic transaction corresponding to the current account and the atomic transaction corresponding to the linked account are generated; the atomic transaction corresponding to the current account is sent to the corresponding system; the atomic transaction corresponding to the linked account is sent to the linkage node corresponding to the system corresponding to the linked account; after receiving the transaction success message of the atomic transaction corresponding to the current account returned by the corresponding system, the transaction success message of the atomic transaction corresponding to the current account is sent to the linkage node corresponding to the system corresponding to the linked account; the linkage node corresponding to the system corresponding to the linked account returns the linkage result according to the transaction result of the atomic transaction corresponding to the linked account and the transaction success message of the atomic transaction corresponding to the current account. In the above process, multi-level linkage does not need to synchronize accounts across systems, and does not affect the performance of the original account operation of the original system. In addition, the transfer-out operation of an account and the transfer-in operation of another account can easily achieve consistency of things due to single-point control. If a certain linkage link fails, the successful linkage operation is complete. The connectivity of the P2P network composed of multiple linked nodes is actually not complicated and has good performance.
