Wherein, when retrodict Day Trading time, update the remaining sum at end day of account table, day according to Day Trading of retrodicting eventually remaining
In volume state and account balance history lists from the actual starting date of Day Trading of retrodicting, to generation day of Day Trading of retrodicting
Remaining sum and balance status.
By each above-mentioned step, the recording method of the dynamic changing data of the embodiment of the present invention, in account table
Add remaining sum item at end day and balance status item at end day, and build account balance history lists, for Day Trading of such as retrodicting
Deng affecting the transaction of history remaining sum, starting corresponding balance updates process, the history that upgrades in time remaining sum, for subsequent query
Or the operation such as interest-bearing provides data support more accurately.
Below in conjunction with concrete example, each step of the recording method of the dynamic changing data of the embodiment of the present invention is carried out
Describe in detail.
Above-mentioned steps S101: initialize the remaining sum and balance status at end day at end day in account table for current account,
And month residing for the same day of opening an account is defined as the N month, the newly-built N month and the account balance history lists of the N+1 month.
In actual application, it is preferred that can be to open an account the same day client, the account table of the account of this client be carried out
Initialize.But initializing account table at different time also dependent on needs, the present invention is not limited thereto.
Account table is used for storing accounts information, and daily night, batch processing carried out updating this table when interest calculates.Initializing should
Account table refers to, remaining sum item and balance status item at end day at newly-built end day in account table, and by remaining sum definition at end day
It is 0, the balance status at end day in account table is defined as " unknown ".Account master meter is as shown in table 1 below.
Table 1
Further, for this client, and newly-built open an account this month and next month (make a distinction during for ease of being described below, will
Open an account and of that month be referred to as first month, the next month in this month of opening an account is referred to as second month) account balance history lists.
Account balance history lists is for record account daily balance and balance status in detail.Account remaining sum history lists such as following table
Shown in 2.
Table 2
When newly-built account remaining sum history lists, by open an account the same day and before the remaining sum on date be defined as 0, remaining sum
State is defined as the unknown；And the remaining sum on date after the same day of opening an account is defined as 0, balance status is defined as " ibid
One day ".
Above-mentioned steps S102, records the remaining sum and balance status at end day at end day of N month n days in account table.
The remaining sum and balance status at end day at end day on account same day is recorded in account table.Specifically, in account table
The process of record remaining sum at end day and balance status at end day is as shown in Figure 2.
Step S201: whether the balance status at end day judging the same day is " unknown "；If it is, perform step S202,
Otherwise perform step S203；
Step S202: the balance status at end day on the same day in account table is updated to " batch updating "；
Step S203: judge whether the remaining sum at end day on the same day changes；If it is, perform step S204, otherwise
Perform step S205；
Step S204: update the remaining sum at end day on the same day in account table according to the change of remaining sum at end day, and day is the most remaining
Volume state is updated to " batch updating "；
Step S205: the balance status at end day on the same day in account table is updated to " ibid one day ".
Above-mentioned step S103, in first scheduled time, according to account table n days record end day remaining sum and
The remaining sum of n days and balance status in day whole balance status more new account balance history lists.
Specifically, the process of more new balance and balance status is as shown in Figure 3:
Whether the balance status at end day first determining whether n days is " batch updating "；If it is, need more New Account
Remaining sum history lists, otherwise need not more new account balance history lists.
If needing more new account balance history lists, then according to n days record end day remaining sum and balance status at end day more
The remaining sum of new n days and balance status.Specifically, it is by the balance updates of n days corresponding in account balance history lists
For the remaining sum at end day of n days, and balance status is updated to " batch updating ".
In a preferred embodiment, the record remaining sum at end day of above-mentioned steps S102 and the process of balance status at end day be
Complete during the batch processing at night on the same day, and the process of the more new balance of above-mentioned steps S103 and balance status is secondary
In the daytime the batch processing of day completes (the first the most above-mentioned scheduled time can be (n+1)th), by asynchronous refresh process,
When can reduce batch processing at night every day, system resource is taken, promote the treatment effeciency to dynamic changing data.
In actual applications, one can be set when carrying out parameter configuration monthly to carry out joining of pre-inserted account balance history lists
Put the date, when this configuration date of first month, the account balance history lists of newly-built second month, and by this second
Remaining sum in the account balance history lists of individual month is defined as 0, balance status is defined as " ibid one day ".
In the specific implementation, it is also possible to be at the account balance history lists setting up open an account this month and next month the same day of opening an account,
And when this configuration date, newly-built trimestral account balance history lists.Specifically, be according to this date with open an account
Before and after, relation determines.
Such as, if open an account day configuration the date before, then the account balance history lists of newly-built first month when opening an account,
Account balance history lists at the configuration date newly-built second month in this month of opening an account；If opening an account, day is after the configuration date,
The then account balance history lists of newly-built first month and second month when opening an account, when the configuration date of second month,
Newly-built trimestral account balance history lists.The example above content is only to illustrate New Account remaining sum history lists
Content, and and be not used to limit the present invention.
The above, for generally, be in batch processing the and during next day of batch processing in the daytime at night every day, for
The process that the remaining sum of account every day and balance status are updated.But in concrete implementation process, for customer account,
It sometimes appear that affect the transaction (Day Trading of retrodicting as because adjusting account to occur) of history remaining sum, the most then need the most more
The remaining sum on the same day on corresponding date in the remaining sum at end day of New Account master meter, balance status at end day, and account balance history lists
And balance status.Specifically, for the remaining sum of relevant date during the transaction of the history remaining sum that makes a difference and balance status
Renewal process is as follows:
When retrodict Day Trading time, first according to the input of user determine this Day Trading of retrodicting actual starting date and send out
Raw dealing money, this actual starting date i.e. refers to, the starting date making history remaining sum change due to this transaction of retrodicting.
In actual applications, this user can be the teller of banking system, teller input this day friendship of retrodicting by terminal unit
Easy actual starting date and dealing money.
Then, from the beginning of the actual starting date of Day Trading of retrodicting, the state that queries the balance forward is " batch updating " or " connection
Machine update " date, this date is defined as the Base day, using the remaining sum of Base day as the baseline amount of money.
This is updated actual initial according to the baseline amount of money and the dealing money of Day Trading of retrodicting, the remaining sum of every day and balance status
Day is to day remaining sum of every day in account balance history lists occurs, and extremely actual starting date is occurred the balance status of day more
It is newly " online renewal ".
Specifically, for actual starting date to each day occurred in day proxima luce (prox. luc), if the balance status on the same day is " not
Know ", then abandon processing the remaining sum on the same day；If the balance status on the same day is " ibid one day ", then by the baseline amount of money and friendship
Easily amount of money sum is updated to the remaining sum on the same day；If the balance status on the same day is " online renewal " or " batch updating ",
Then the remaining sum current same day and dealing money sum are updated to the remaining sum on the same day.
Day Trading of retrodicting be there is to the balance status of day, then in a scheduled time (the e.g. next day of this generation day)
In the daytime during batch processing, according in account table this generation day end day remaining sum and balance status at end day come more than more New Account
The remaining sum of this generation day and balance status in volume history lists.
The recording method of the dynamic changing data of the embodiment of the present invention, in effectively record account balance history for business scenario
On the premise of use, by the way of asynchronous refresh, by specifically balance updates procedural arrangements next day in the daytime batch
In processing procedure, thus alleviate the impact for batch time window at night to greatest extent, improve treatment effeciency.
Further, the recording method of the dynamic changing data of the embodiment of the present invention, related to account balance is updated
Capital log history remaining sum, for non-Day Trading of retrodicting, can record remaining sum at end account day when batch processing at end day, and
Start batch program next day to update in history balance sheet；For Day Trading of retrodicting, history can be carried out in transaction simultaneously
The adjustment of upper remaining sum, the remaining sum change in this day caused simultaneously for this transaction, can be updated by batch program next day equally
In history balance sheet.
Below in conjunction with a concrete example specifically processing the recording method of the dynamic changing data of the embodiment of the present invention
Journey is described further.
