Embodiment one
The present embodiment one discloses a kind of cross-section data backup method, and described method is intended to solve the problem that existing banking system cannot carry out account transaction every day in time window, so realize online service 7*24 hour available.
The cross-section data of account field (such as account balance) when cutting day to record, ensure the accounting processing in time window, such as Clearing, report form statistics etc. can be carried out like clockwork, account field is not locked simultaneously, ensure that account transaction still can normally be carried out in time window, the present invention proposes two balance field mechanism, namely in account information database for account balance field adds a remaining sum mirror image field, backup support is provided with the content being embodied as account balance field, add in a database simultaneously one lock in time field, for when the content of remaining sum mirror image field to account balance field backs up, the lock in time of real time record two field contents.
The Sino-Japan point of contact of the present invention is specially zero point, and meanwhile, the Sino-Japan point of contact of the present invention is also the initial time of time window.
With reference to figure 1, the every content of database after adding remaining sum mirror image field and lock in time field included by accounts information has been shown in Fig. 1, wherein, " account balance " and " time " is respectively original field of database---the content of account balance field and time field (time of the last transaction of record), " account balance cross section value " and " lock in time " are respectively the field that the present invention adds---remaining sum mirror image field (account mirror image field) and lock in time field content.After entry time window, account balance field, time field are open to account transaction, can the change with the submission of account transaction.
Be described in detail to the inventive method below, with reference to figure 2, cross-section data backup method of the present invention can comprise the following steps:
S101: the submission request receiving account transaction, described submission request comprises target account, account type of transaction and transaction limit.
Wherein, account trading type can be all kinds such as to deposit and withdraw, transfer accounts, and when submitting account transaction to banking system, banking system needs according to account type of transaction and transaction limit, carry out the increase and decrease operation of corresponding amount to account balance.
S102: judge whether the transaction of described account meets following condition: the submission request of described account transaction is in time window and the transaction of described account is the first stroke account transaction after everyday cutting.
Wherein, specifically judge whether the submission request that described account is concluded the business is in time window by following process: flag information a) reading time window from the time window attribute field preset; If b) described flag information characterization time window is opening, then the submission request of described account transaction is in time window; If c) described flag information characterization time window is closed condition, then the submission request of described account transaction is in outside time window.
Such as, particularly, a time window attribute field can be pre-set, and the content supposing this field when being 0 characterization time window open, namely enter the accounting processing stage, characterization time close when the content of this field is 1, does not namely also enter the accounting processing stage or accounting processing terminates.Based on this setting, banking system can per next day cut laggard enter accounting processing time, the content of this field is set to 0, and at the end of accounting processing, the content of this field is set to 1.Thus on this basis, when submitting account transaction to, the content namely by reading this field judges whether current account transaction is in time window.
If current account transaction is in outside time window, then the judged result of step S102 is no, without the need to carrying out follow-up judgement operation again, if current account transaction is within time window, then step S102 need continue to judge that whether the transaction of described account is the first stroke account transaction after everyday cutting.
In the present embodiment, judge whether described account transaction (being in time window) is when the first stroke account transaction after everyday cutting by following process: a) read information lock in time from the lock in time of described target account field; If the date b) in information described lock in time is not the date on the same day, then described account transaction is the first stroke account transaction after everyday cutting; If the date c) in information described lock in time is the date on the same day, then described account transaction is not the first stroke account transaction after everyday cutting.
Particularly, the present invention specifies that the back-up job of cross-section data is realized by the first stroke account transaction in time window.Based on this prerequisite, when the transaction of a certain account is submitted to, if the date of lock in time is not the date on the same day in lock in time field, then characterize the same day also non-pair cross-section data back up, thus the transaction of described account is the first stroke account transaction in time of day window; On the contrary, if the date of lock in time is the date on the same day in lock in time field, then characterize the back-up job completing cross-section data the same day, therefore, described account transaction is not the first stroke account transaction in time of day window.
S103: if the determination result is YES, then proceed as follows the accounts information of described target account: by account mirror image field in target account and lock in time field content change to the cross-section data of account field in described target account and current real-time time respectively; According to described type of transaction and transaction limit, the content of account field in target account is modified, and be current real-time time by the content modification of time field in target account.
Because the present invention specifies that the back-up job of cross-section data is realized by the first stroke account transaction in time window.Therefore, if the judged result of step S102 is yes, namely described account transaction is the first stroke account transaction in time window, then first need cross-section data current for account balance field to be synchronized in remaining sum mirror image field, realize pair cross-section data to back up, the lock in time that simultaneously real time record is current in lock in time field, afterwards, can carry out normal account transaction, foundation type of transaction and the account balance of transaction limit to target account are modified and are current real-time time by the content modification of time field.Thus in not influence time window while normal account transaction, also for accounting processing remains available cross-section data.
From above scheme, the present invention is directed to the demand conflict existed when banking system carries out accounting processing and account transaction in time window, add in account information database in advance mirror image field and lock in time field, to realize carrying out when the first stroke account after everyday cutting is concluded the business in time window, before this transaction submission comes into force, account field cross-section data is at that time backed up, and real time record lock in time at that time, for accounting processing is carried out providing guarantee like clockwork; Meanwhile, be that accounting processing remains available cross-section data owing to adopting account mirror image field, thus banking system need not lock account field in time window again, can modify according to the content of account trading situation to account field of reality.Thus application the present invention can to ensure account transaction 7*24 hour available, eliminate the limitation that the transaction of account in prior art exists.
Embodiment two
In the present embodiment two, with reference to figure 3, described method can also comprise the following steps:
S104: if judged result is no, then modify to the content of account field in described target account according to described type of transaction and transaction limit, and be current real-time time by the content modification of time field in target account.
Particularly, if described account transaction is not the first stroke account transaction in time window, such as, if described account transaction is the N transaction in time window, then because the pair cross-section data of concluding the business of the first stroke in time window back up, thus for the accounting processing in time window has retained data available, without the need to again backing up; If described account transaction is the transaction carried out after time window terminates, then because time window terminates, thus the accounting processing on the same day also terminates, therefore without the need to backing up again.
Thus, when described account transaction is not the first stroke account transaction in time window, banking system, can the type of transaction of this transaction of direct basis and the account balance of transaction limit modifying target account without the need to carrying out the backup-step of cross-section data, and records exchange hour simultaneously.
Embodiment three
In the present embodiment three, with reference to figure 4, described method can also comprise the following steps:
S105: in time window, when receiving accounting processing request, reads information lock in time from the lock in time of described target account field;
S106: if the date in described lock in time information is not the date on the same day, then adopt the account field information of target account to carry out accounting processing;
S107: if the date in described lock in time information is the date on the same day, then adopt the mirror image field information of target account to carry out accounting processing.
After cutting day, in time window, banking system needs to carry out some as the accounting processing such as Clearing, report form statistics, owing to present invention employs two remaining sum mechanism, thus, when carrying out accounting processing, need first determine adopt source remaining sum content still to back up remaining sum content.
Particularly, when receiving accounting processing request, can determine needing the remaining sum adopted according to information lock in time in lock in time field, when in this field, the date of lock in time is not the date on the same day, then characterize the back-up job of also not carrying out cross-section data the same day, also characterize after cutting day simultaneously in the time window on the same day, also do not carry out account transaction, therefore, need employing source remaining sum content, namely the content of source account balance field carries out accounting processing.If the date of lock in time is the date on the same day, then carried out account transaction in the time window characterizing the same day, and therefore needed to adopt the cross-section data of backup on the same day to carry out accounting processing.
