Description
Technical field
The embodiment of the present invention is related to Object Management group, and in particular to uses user information to the remainder of object based on last
The method and apparatus reduced.
Background technique
In Object Management group field, need to reduce the remainder of object when user requests object, and when user cancels
Need to restore the remainder of object when request.In order to smoothly realize the adjustment of object, in the prior art, two kinds of sides are proposed
Case is related to for object related parameter being stored in a table or a caching, when needing regulating object to relevant field or
Attribute is modified.Specifically, in the first scheme, using the mark of object and remainder as a record storage in data
In the table of library, when user requests object, is inquired first according to object identity and judge whether remainder reduces enough, then again
Update remainder；When user's cancellation request, remainder is restored according to object identity.In second scheme, by object identity,
Object sum has used sum as a record storage in database table, when user requests object, first according to object
Whether mark is inquired and is judged object sum and reduced enough with the difference of sum, then updates again and has used sum；When user takes
Disappear when requesting, sum has been used according to object identity reduction.
It is negative however, all presence of the first scheme and second scheme may cause remainder (that is, having used sum is more than pair
As sum or referred to as object excess deduction) the problem of.The first scheme is to judge whether remainder is big when reducing remainder
In or equal to number of request, second scheme is to judge to have used whether the sum of sum and number of request are less than or equal to object sum.But
It is that two schemes have a common problem, i.e., it, can when existing simultaneously the case where restoring remainder and reducing remainder
Object excess deduction and remainder object can occur but the case where user can not request use.
For example, when the remainder of object is 20, the number of request of thread A is 15 and the number of request of thread B is 10, it can
Following several situations can occur: remainder is that 5 (thread A reduces success, and then thread B judge remainder not enough therefore reduces mistake
It loses)；Remainder is 10 (thread B reduces success, and then thread A judges therefore remainder is not enough reduced unsuccessfully)；And remainder
For -5, (thread A judges that remainder is reduced enough, and thread B judges that remainder is reduced enough, and then thread A and thread B are carried out respectively
Object is reduced).In addition, if occurring thread C reduction remainder at this time, then situation can be more complicated.
In order to solve the problems, such as the object excess deduction being likely to occur, proposed in the prior art by increasing a word
The method of Duan Jinhang gradually training in rotation.In the method, remainder is first inquired, then thread progress object is reduced one by one.In the party
In method, it may be necessary to update multiple database, that is, carry out multiple write operation to database.However, this mode performance it is lower and
Resource consumption is larger.
Therefore, in Object Management group, when existing simultaneously multiple users' request objects and cancellation request, due to concurrently causing
The probability for occurring object excess deduction when reducing and restore remainder is very high, so that user is apprised of after requesting object not to be had
The appearance of the case where object.In order to solve the problems, such as object excess deduction and remainder object but user can not request use,
Need to propose the simple and practical mode of one kind to prevent the appearance of object excess deduction and make full use of remaining object, thus real
Existing higher Object Management group efficiency consumes less resource simultaneously.
Summary of the invention

Language "and/or" includes any and all combinations for the project that one or more correlations are listed.
Next, with reference to Fig. 1 description for based on the last method for reducing remainder using user information.
Firstly, creating database table in step 101, which includes the mark of object, object sum, has used always
Counting, finally using attributes, the attributes such as user information is one-to-one relationship.One mark is opposite with a specific object
It answers.For example, object can be bandwidth, capacity, product etc..In the case where object is product, object is identified as product
Corresponding keeper unit (Stocking Keeping Unit, sku), and including with properties, such as product type,
Product type, product colour, product size, product memory, product function, product capacity etc..Finally include using user information
Finally using user identifier and the last timestamp for requesting object using user.The timestamp can be as accurate as millisecond.
Then, in step 102, it is total that object is obtained from database table according to mark corresponding to the object of user's request
Number has used sum and has finally used user information.Specifically, the mark phase for the object requested with user is inquired from database table
With mark, and is obtained from database table according to the mark inquired object corresponding with object is total, it is total to have used,
And finally use user information." request " herein can be different according to object, for example, when object is bandwidth, request
Object can be understood as request using bandwidth, and when object is product, request object can be understood as request purchase product.
Next, judging the object sum obtained in step 103 and whether being greater than 0 with the difference delta of sum.If
Delta is less than or equal to 0, then in step 104, reduces without object, and returns to request failure message to user.
If delta is greater than 0, in step 105, it will be updated to use sum salenum and be used with sum salenum
The sum of the number of request n at family, and request the timestamp of object finally to be believed using user to update using the mark of user and user
Breath.Then, it in step 106, is inquired more from database table according to the mark of object and updated last use user information
Sum has been used after new.
If do not inquired updated with sum (for example, this may be since another user also leads in request object
Database table is caused to be again updated), then in step 107, database table is not updated, and return to request success message to user,
The request success message includes that the number of request of instruction user is the information of n.
If inquire it is updated used sum, in step 108, judge updated to have used sum and object sum
Difference m whether be greater than 0.If m is less than or equal to 0, in step 109, database table is not updated, and return and request to user
Success message, the request success message include that the number of request of instruction user is the information of n.If m is greater than 0, in step 110,
The difference of sum with m will be updated to have used with sum in database table, and is returned to user and request success message, the request
Success message includes that the number of request of instruction user is the information of n-m.
In the following, by by taking object is the product that user requests purchase as an example, to for being based on finally reducing using user information
The method of remainder is described in detail.
It is assumed that the user of thread A requests 5 products of purchase, and the product obtained from database table in a step 102
Object sum be 20 and be 10 with sum.In step 103, calculating object sum and having used the difference of sum is 10,
Greater than 0, therefore in step 105,15, and the user for being thread A by last purchaser's information update will be updated to sum
Information.If the user of thread B requests 3 products of purchase at this time, and will use sum by step 102 to step 105
18 are updated to, and by the information for the user that last purchaser's information update is thread B, then in step 106, the user of thread A
Can not be inquired from database table it is updated used sum, therefore number is not updated for the user of thread A in step 107
Purchase success message is returned to according to library table, and to the user of thread A, which indicates that the purchase number of the user of thread A is 5.It is right
In the user of thread B, since last purchaser's information has been updated to the information of the user of thread B, in step 106, thread B
User inquired from database table and updated used sum.Then, in step 108, judge m for -2, less than 0, therefore
In step 109, database table is not updated, and returns to purchase success message to the user of thread B, which indicates thread B's
The purchase number of user is 3.
In another example, it is assumed that the user of thread A requests 5 products of purchase, and in a step 102 from database
The object sum of the product obtained in table is 20 and has been 10 with sum.In step 103, it calculates object sum and has used
The difference of sum is 10, is greater than 0, therefore in step 105, will be updated to 15 with sum, and by last purchaser's information update
For the information of the user of thread A.If the user of thread B requests 6 products of purchase at this time, and passes through step 102 to step
105 will be updated to 21 with sum, and by the information for the user that last purchaser's information update is thread B, then in step
The user of 106, thread A can not be inquired from database table it is updated used sum, therefore in step 107, for thread A
User, do not update database table, and return to purchase success message to the user of thread A, which indicates the user of thread A
Purchase number be 5.For the user of thread B, since last purchaser's information has been updated to the information of the user of thread B,
In step 106, the user of thread B inquires from database table updated has used sum.Then, in step 108, judge m
It is 1, is greater than 0, therefore in step 110,20 will be updated to sum in database table, and return to the user of thread B
Success message is bought, which indicates that the purchase number of the user of thread B is 5.
By the above process, realize the remainder progress that the product of purchase is requested based on last purchaser's information user
It reduces, avoids and the case where product excess deduction occur, without product situation after user will not being caused to buy successfully
Occur.
