When, need to first determine attribute value of the destination multimedia data on each attribute, in order to according to destination multimedia data each
Attribute value on attribute stores destination multimedia data.
Wherein, the attribute of destination multimedia data includes the grading system of destination multimedia data, destination multimedia data
Uplink time and destination multimedia data stylistic category.For example, grading system may include 1 star, 2 stars, 3 stars, 4 stars and 5
Star, stylistic category may include the seventies, the eighties, the nineties, the 00's.
In addition, N is pre-set numerical value, which can be 2,3 or 4 etc..
For example, destination multimedia data are song, two attributes of N 2, destination multimedia data are respectively grading system
And uplink time, that is, multi-medium data is stored according to grading system and uplink time.
Step 202：According to the one-to-one attribute value of N number of attribute, determine the corresponding M target of destination multimedia data
Characteristic, M are the positive integer more than or equal to 1 and less than or equal to N.
In practical application, for certain attributes, if the corresponding all properties value of the attribute is enumerated to come, and according to each
Different attribute values store multi-medium data, will increase the difficulty of storing multimedia data, therefore, implement in the present invention
In example, media data is stored according to each different characteristic.
Wherein, each characteristic is for describing attribute, that is, characteristic is for describing attribute value within the specified range one
Attribute.For example, if characteristic is the characteristic for grading system, characteristic can be that grading system is 3 stars, or, or
Grading system is below Samsung.If characteristic is the characteristic for uplink time, characteristic can be uplink time in January, alternatively,
Uplink time is in 2 months etc..
Further, in order to quickly determine the corresponding target property of destination multimedia data, a characteristic row are pre-set
Table, which includes multiple characteristics, at this point, the realization method of step 202 can be：
For N number of attribute, the matched characteristic of attribute value corresponding with each attribute is searched from characteristic list, will be found
Characteristic be determined as the corresponding target property of destination multimedia data, to obtain the M target property.
For example, characteristic list includes 5 characteristics for grading system, respectively grading system is 1 star, grading system is
2 stars, grading system are 3 stars, grading system is 4 stars and grading system is 5 stars, and for 12 characteristics of uplink time, are divided
Not Wei uplink time January, uplink time 2 months ..., uplink time is in December.
If attribute value of the destination multimedia data in attribute ratings grade is 4 stars, the attribute on attribute uplink time
Value is October 20, then when two characteristics that can obtain destination multimedia data are respectively that grading system is 4 stars and uploads
Between in October.
Step 203：Each target signature and user identifier in the M target property are combined, M object key is obtained
Key in value, and the mark of the destination multimedia data is added in the value in each target key value.
In embodiments of the present invention, corresponding multi-medium data is directly obtained according to attribute value in order to realize, with key
The mode storing multimedia data of value.In addition, due in practical application, other users are typically to make attribute value and user identifier

A key directly obtains and the user identifier and the corresponding multi-medium data of characteristic.
In addition, for the information that the value for simplifying key assignments includes, the value in each key assignments can also be the use for including with key
Family identifies and the mark of the corresponding multi-medium data of characteristic, that is, the value in each key assignments is for storing multimedia data
Mark.
Therefore, after obtaining destination multimedia data corresponding M target property by step 202, it may be determined that mesh
The mark for marking multi-medium data, each target signature and user identifier in the M target property are combined, M mesh is obtained
The key in key assignments is marked, and the mark of the destination multimedia data is added in the value in each target key value, to realize mesh
Mark multi-medium data is stored in a manner of key assignments.
It further, will be more in the value in the key assignments in key assignments list in order to improve the efficiency for obtaining multi-medium data
The mark of media data is stored according to batch mode, and the maximum quantity of the mark for the multi-medium data for including per a batch is k, and k is
Positive integer more than 1, in order to can subsequently export the corresponding multi-medium data of value of some key-value to terminal in batches.
At this point, each the mark of the multi-medium data in the value in target key value is stored according to batch mode, and therefore, step
203 are specifically as follows：For the value in either objective key assignments A in M target key value, the mark with destination multimedia data is determined
The mark of destination multimedia data is added in object lot by corresponding object lot.
That is, for target key-value A, an object lot need to be first determined, in order to by the mark of destination multimedia data
It is added in object lot, is stored the multi-medium data into the value of target key-value A with realizing.
It should be noted that the mark for the multi-medium data for including for the value in any key assignments, it can be according to certain
Sequence stored, naturally it is also possible to directly postpone arrangement storage.Accordingly, it is determined that corresponding with the mark of destination multimedia data
Object lot can have following two possible realization methods：
The first possible realization method, the mark of the multi-medium data in the value in key assignments in key assignments list is according to right
The size sequence of attribute value of the multi-medium data answered in specified attribute is stored, at this point, determining destination multimedia data
Attribute value in the specified attribute determines the multi-medium data at end of sorting in each batch in the value in target key value A
Identify attribute value of the corresponding multi-medium data in the specified attribute；According to the multi-medium data at end of sorting in each batch
Attribute value and destination multimedia data of the corresponding multi-medium data of mark in the specified attribute in the specified attribute
Attribute value determines object lot.
Wherein, specified attribute is pre-set attribute, for example specified attribute is grading system, at this point, for object key
The mark of the multi-medium data in value in value A, by the mark of multi-medium data according to the scoring etc. of corresponding multi-medium data
The size sequence of grade is stored.For another example, specified attribute is uplink time, for the multimedia in the value in target key value A
The mark of data deposits the mark of multi-medium data according to the size sequence of the uplink time of corresponding multi-medium data
Storage.
The mark of second of possible realization method, the multi-medium data in the value in key assignments in key assignments list is directly suitable
Prolong arrangement storage, at this point, the last one batch in the value in target key value A is directly determined as object lot.
The maximum quantity of the mark for the multi-medium data for including due to every a batch is k, by destination multimedia data
Mark be added in object lot after, also need the quantity of the mark for the multi-medium data for judging that object lot includes whether big
In k, in order to which the mark to the multi-medium data in each batch adjusts.
Specifically, it is determined that the quantity of the mark for the multi-medium data that object lot includes, if more matchmakers that object lot includes
The quantity of the mark of volume data is more than k, then stores the mark of the multi-medium data at end of sorting in object lot to next group
In secondary, for each batch after object lot, according to the sequence of each batch, if successively execute present lot include it is more
The quantity of the mark of media data is more than k, then stores the mark of the multi-medium data at end of sorting in present lot to next
Step in batch.
For example, k is 10, there are 5 batches, object lot 3, at this time by destination multimedia data in the value of target key-value A
Mark store into third batch after, the mark of 11 multi-medium datas will be included in third batch, is needed at this time by third
The mark conduct for the multi-medium data that the mark of the multi-medium data at sequence end is transferred in the 4th batch, and shifts in batch
First multi-medium data mark in 4th batch.The multi-medium data that 4th batch Central Plains includes is postponed successively, and determines the
The quantity of the mark for the multi-medium data that four batches include continues the mark for the multi-medium data for judging that the 4th batch includes
Quantity whether be more than k, the above process is repeated, until the last one batch more matchmakers for including in the value of target key-value A
The quantity of the mark of volume data is less than or equal to k.
In the way of step 201 to step 203 after storing multimedia data, following step 204 to step can be passed through
Rapid 208 obtain multi-medium data.
Step 204：The data acquisition request for the carrying specified requirements that terminal is sent is received, which includes user's mark
Know and at least one attribute.
Wherein, user identifier is the corresponding user identifier of multi-medium data to be obtained.Specifically, when user's B needs obtain
When taking the multi-medium data of family C, user B can be obtained by terminal to server transmission data and be asked, which asks
Seek at least one attribute of the user identifier and multi-medium data to be obtained that carry user C.
For example, specified requirements includes the user account that user C is registered on the server and grading system is 3 stars.Then table
Grading system is the multi-medium data of 3 stars in the multi-medium data of bright user B user C to be obtained.
