Embodiments provide a kind of date storage method and device, as shown in figure 1, Fig. 1 is the embodiment of the present invention
A kind of date storage method flow chart, including：
S101：Data to be stored is saved in system database；
Specifically, in user network activity, by the service request of system server receive user, complete user network
The various data messages of user network activity can be considered as data to be stored, such as user is accessing certain by the corresponding operating of activity
During individual website, website visiting number of times can be considered the data to be stored of user network activity, and user browses click website in website
During the page, page number of clicks can be considered data to be stored of user network activity etc..
Because server needs to respond service request being processed, in general server should possess the service of undertaking and
Ensure the ability of service, therefore will at aspects such as disposal ability, stability, reliability, security, extensibility, manageabilitys
Ask higher.Database server provides data, services for user network activity.Database server is set up in system database base
On plinth, there is the characteristic of system database, database server has system database management function, including system configuration and pipe
Reason, data access manage data security management with more new management, data integrity；The inquiry of database and operating function,
This function includes database retrieval and modification；Database maintenance function, imports/derives management including data, and database structure is tieed up
Shield, data recovery function and performance monitoring；Data base concurrency runs, because in the same time, the user accessing database is more than
One, so database server must support parallel running mechanism, process and occur while multiple event.Database server
While providing various application services operation for User Activity, finally the data to be stored of user network activity is saved in and is
In system database.
For example, count website visiting number of times when, that is, user access some websites when, server respond first user visit
Ask request, database server imports this user's access times, including the data access that this user is accessed and more new management, number
According to inquiry and manipulation, database retrieval and the modification, database maintenance etc. in storehouse, the most at last this user's access times record in system
In database, by that analogy, the website visiting number of times of all users of the final keeping records of system database, you can count this net
Stand access times.
S102：Obtain the data to be stored preserving unsuccessfully；
Specifically, when above-mentioned database server is when being saved in data to be stored in system database, it is understood that there may be
User's access times are excessively frequent or database server does not respond to user network work in certain time point or in the time period
Dynamic, lead to this time point or the data to be stored of the user network of time period activity cannot be saved in system database.
In embodiments of the present invention, setting caching server preserves data to be stored unsuccessfully obtaining system database.

For example, count website visiting number of times when, the most at last user's access times record in system database, but due to
User's access times are excessively frequently excessive to this website number of clicks or other reason, database server in certain time point or
User website access times are not saved in system database in time period, are obtained by the data of the caching server of setting
Take service to obtain the user's access times not having to preserve of this time point of system database or time period, be arranged on buffer service
This user's access times is considered as preserving data to be stored unsuccessfully by the service that having in device preserves function, user is accessed secondary
Number is temporarily stored in caching server.
S104：In the data Cun Chudao system database to be stored preserving unsuccessfully that will store in caching server, until
Data to be stored unsuccessfully is preserved in system database.
Specifically, the service that sends by being arranged in caching server preserves keep in caching server unsuccessfully
Data is activation to be stored receives what caching server sent to system database, the data reception service in system database
Preserve data to be stored unsuccessfully, and in calling system database, data preserves service to preserve the treating unsuccessfully of preserving receiving
Data storage, in caching server, the data to be stored of all preservation failures of caching is saved in system database the most at last.
For example, count website visiting number of times when, the most at last user's access times record in system database, but due to
User's access times are excessively frequently excessive to this website number of clicks or other reason, database server in certain time point or
User website access times are not saved in system database in time period, are obtained by the data of the caching server of setting
Take service to obtain the user's access times not having to preserve of this time point of database or time period, be arranged in caching server
Have preserve function service this user's access times not preserved is considered as preserving data to be stored unsuccessfully, by user
Access times are temporarily stored in caching server.Will be temporary in caching server by the transmission service being arranged in caching server
User's access times be sent to system database, the data reception service in system database receive caching server send
The user's access times come, and call data in database to preserve service to preserve the user's access times receiving, the most at last
In caching server caching all user's access times be saved in database corresponding to this website visiting number of times statistics
In data, so, website visiting number of times can just be counted exactly.
A kind of date storage method that the present invention provides, is by arranging a caching server, using caching server

In preset time period caching server periodically by the data is activation to be stored preserving unsuccessfully of wherein preservation to system database,
Realize caching server and updating ability is preserved to the data timing to be stored preserving unsuccessfully.
Specific practice is：Call in caching server and send service, to being saved in buffer service in preset time period
The data timing to be stored preserving unsuccessfully in device sends, and the reception service in database receives in caching server and sends
The data to be stored preserving unsuccessfully, be arranged in caching server preserve service by database receive come preserving unsuccessfully
Data to be stored preserves, until the data to be stored preserving unsuccessfully that the caching server in this time cycle sends all preserves
In database.
For example, when counting website visiting number of times, by the distributed caching memcached being arranged in caching server
Method of increasing income obtains the user's access times not have preservation of database time point or time period, and caching server is by this data
It is considered as preserving data to be stored unsuccessfully, user's access times are temporarily stored in caching server.In implementation process, to caching
Server arranges a preset time period, in preset time period, caching server is scanned, and detects buffer service
User's access times whether are preserved, if detect preserving user's access times, buffer service in caching server in device
User's access times of preservation are sent to system database by the method for increasing income of the memcached in device, connecing in system database
Conquer business and receive the user's access times sending in caching server, the preservation service in caching server of being arranged on is by number
Receive the user's access times come to preserve according to storehouse, the user's access times preserving in caching server the most at last are all saved in and are
In the corresponding data to this website visiting number of times statistics in system database, realize to the correct system counting this website visiting number of times
Meter, deviation in the statistics preventing loss of data and causing.
It should be noted that arranging other data in buffer service to preserve service or method, by preserve unsuccessfully wait deposit
Storage data is saved in caching server, broadly falls in the protection domain of this patent.
By Preset Time is arranged to caching server, in preset time period, caching server is scanned, will

Business device preserves overabundance of data and causes data corruption and to caching server build-up of pressure, improves caching server data keeping quality
Can, in addition to system database, according to Preset Time, the data timing to be stored preserving unsuccessfully can be saved in system database
In, also avoid data all in caching server are disposably saved in the pressure of system database.
Preferably, in a kind of data Cun Chudao system to be stored preserving unsuccessfully by storage in caching server of the present invention
In embodiment in system database, including：
When the data capacity to be stored preserving unsuccessfully of storage in caching server exceedes predetermined threshold value, by caching server
In the data Cun Chudao system database to be stored preserving unsuccessfully of middle storage.
Specifically, a threshold value is arranged to the data storage capacity of caching server, data preserves in caching server
The data to be stored preserving unsuccessfully is saved in caching server for service, and setting program obtains the preservation that caching server preserves
The data capacity to be stored of failure and the threshold value of the data storage capacity setting to caching server, and compare both big
Little, if the data capacity to be stored preserving unsuccessfully that caching server preserves is more than the data storage capacity to caching server
The threshold value of setting, then the data is activation service in caching server by be saved in caching server preserve unsuccessfully to be stored
Data is sent in sequence in system database, and the data reception service of system database accepts the preservation that caching server sends
The data to be stored of failure, and the data to be stored of all preservation failures that caching server is sent is saved in system data
In storehouse.
For example, when counting website visiting number of times, obtained by the memcached method of increasing income being arranged in caching server
Take the user's access times not having to preserve of system database time point or time period, this data is considered as protecting by caching server
Deposit the data to be stored of failure, user's access times are temporarily stored in caching server.In implementation process, to caching server
Data storage capacity one threshold value is set, the memcached being arranged in caching server increases income what method will not preserve
User's access times are saved in caching server, and setting program obtains the user's access not having to preserve that caching server preserves
Number of times data capacity and the threshold value of the data storage capacity setting to caching server, and compare both sizes, if slow
The user's access times data capacity not have to preserve depositing server preservation sets more than to the data storage capacity of caching server
The threshold value put, then the user's access times being saved in caching server are sent out by the data is activation service in caching server successively
Deliver in system database, the data reception service of system database accepts user's access times that caching server sends,
And user's access times of all preservation failures that caching server sent be saved in system database corresponding to this
In the data of website visiting number of times statistics, realize, to the correct statistics counting this website visiting number of times, preventing to this partial data
