Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, below in conjunction with the embodiment of the present invention
Accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described.
Technical scheme provided in an embodiment of the present invention is introduced with reference to Figure of description.
Fig. 1 is referred to, the embodiment of the present invention provides a kind of data access method, and the flow of this method is described as follows：
S101：Whether there is each database in the multiple databases for multiple bursts that detection the first data of storage are divided into
Effect；
S102：Part or all of database in effective database is conducted interviews.
In the embodiment of the present invention, the first data can be understood as data to be visited, it is contemplated that the first data are stored in
One tables of data, just need to operate whole tables of data when conducting interviews to the first data, add the burden of database.
In order to mitigate the burden of database, the database summary table of the first data is carried out according to certain rule, also referred to as burst rule
Burst, multiple bursts are divided into, multiple bursts are disperseed to be stored in multiple databases.
, can be according to time rule, such as by the order data in units of the moon for example, for the order data table of 1 year
Table is split, and can be divided into 12 sub- order data tables, and one of those sub- order data table can be understood as one point
Piece.Multiple bursts can be stored on a server, can also be stored on multiple servers.To the access process of data,
The process that exactly data in multiple bursts on one or more server are conducted interviews.
User can be conducted interviews by the data of terminal-pair first, when being conducted interviews to the first data, just be needed first
Which database where knowing multiple bursts that the first data to be accessed include has, to be grasped in these databases
Make, realize and access the first data.Which database where determining multiple bursts that the first data include has can pass through burst
Route implementing.Burst route is correspondingly arranged on routing rule, and routing rule is corresponding with burst rule, and burst route can pass through road
As multiple bursts included by rule calculates the first data, and the database where multiple bursts.In the embodiment of the present invention, point
Piece route can be set in the terminal, can also be set in the server, or can also be set independently of terminal and server
Between terminal and server.
Burst route receives data access request, can calculate outlet according to data access request and the routing rule of setting
By result, that is, store at least one Database Lists of multiple bursts included by the first data.Wherein, at least one number
The list of the address of database where including the list of the burst included by the first data, and/or burst according to storehouse list.Burst road
After calculating route results, the route results of calculating can be fed back to terminal, so that route of the terminal according to reception
As a result the address of database where obtaining the list of the burst included by the first data, and burst, so as to be wrapped to the first data
Database where the multiple bursts included is operated, to obtain the first data to be accessed.
Because the data of database may break down, then it is all effective at any time that can not just ensure database
, for example, the tables of data of database purchase is actually what is be not present, caused database can not be accessed, even if having accessed
The database also cannot get the first data, i.e. the success rate of data access is relatively low.In this case, terminal just can not be visited successfully
The first data are asked, this just needs terminal to access database again, and request obtains the first data, inevitably, terminal and burst
It is just more to route the number of interaction, causes the less efficient of data access.
Therefore, the number interacted in order to avoid terminal and burst route is more, the efficiency of data access is improved, in the present invention
In embodiment, when multiple databases where the multiple bursts being divided into the first data of storage conduct interviews, it can detect
Whether each database is effective in this multiple database, and database effectively refers to that database may have access to here.With only to effective
Database conduct interviews, directly abandon accessing for invalid database, interaction times during so as to reduce access, reach
Improve the purpose of access efficiency.
Each data in the multiple databases for multiple bursts that detection the first data of storage of the embodiment of the present invention are divided into
Whether storehouse is effective, can detect whether the network port corresponding to each database may have access to, and can check each database sheet
Whether body may have access to, or can also check whether the tables of data to be accessed in each database exists in database, and
The tables of data can also access in itself.If the network port corresponding to a data place can access, it is considered that the number
Effective according to storehouse, similarly, if a database can access in itself, the database is also effective.Three of the above detects
Situation is merely illustrative, and in the embodiment of the present invention, whether effective, can also all consider three kinds of situations if detecting each database
Enter, once all detected three cases above, so may further determine that effective database, visited with reducing as far as possible
Ask the possibility of invalid database.Certainly, database is effectively not limited to several situations of the above, in addition to other possible feelings
Condition.
Each data in the multiple databases for multiple bursts that detection the first data of storage of the embodiment of the present invention are divided into
Whether storehouse can also can effectively be route by terminal by burst, can also be realized by server.Wherein, detect multiple
Whether each database in database can effectively be carried out in the following two cases.
The first situation：Burst route can be detected after route results are calculated, to be visited only to detect
Database validity, the negligible amounts of the database detected, detection efficiency is higher, can also mitigate detection burden.This
It in inventive embodiments, except burst is route, can also be detected by terminal after route results are calculated, now just need to divide
Piece route informs terminal when calculating route results, is examined as the validity of the database included by terminal-pair route results
Survey.Certainly, in the embodiment of the present invention, the detection to the validity of the database included by route results is not limited by burst road
By being realized with terminal, can also be realized by other possible equipment, such as server.
Second of situation：Burst route can also be directed to all databases stored on server and periodically be examined
Survey, to be periodically monitored to all databases, when finding to have invalid database, be easy in time to invalid data
Safeguarded in storehouse.The setting in cycle can rule of thumb be set, such as the frequency that database breaks down is every 30 minute/time,
It is exactly 30 minutes that the cycle, which can so be set,.The setting in cycle can also measure gained according to actual experiment, on the other hand, the present invention is not
It is restricted.
Under this detection mode, after burst router-level topology goes out route results, the route results that will can calculate
Included database is compared with the efficient database for being periodically detected to obtain, if the database included by route results
In some or some databases not in the range of the efficient database for being periodically detected to obtain, then it is considered that some or it is some
Database is invalid database.Burst route all database that the route results fed back to terminal can include calculating,
Efficient database can also be only included.When burst route the route results fed back to terminal and only includes efficient database, i.e. burst
Route after can invalid data storehouse be removed, then feeds back to terminal after route results are calculated.
In addition, when burst route detects the presence of invalid database, invalid database can be reported other and set
It is standby, such as terminal, know invalid database be present so as to terminal, invalid database is safeguarded.Certainly, the present invention is real
Apply in example, server can also be directed to all databases stored on server and periodically be detected, with periodically
All databases are monitored, when finding to have invalid database, are easy in time safeguard invalid database.
If it is determined that invalid database be present, then also can thinks first be stored in invalid database
The partial data of data be access less than, that is, the first data that terminal finally gives are incomplete.And invalid data
Storehouse is likely to be database in use, and because some situations break down and it is invalid to cause.For example, for certain data
For table, when initial, this tables of data is stored in database, in using process, is deleted due to maloperation,
So now the database is exactly invalid.Under the circumstances, the embodiment of the present invention can also be to storage the first data point
The multiple databases for the multiple bursts being cut into are backed up, and wherein the data in backup database can pass through data duplication instrument
Realize consistent with the data in multiple databases.
In the presence of backup database, the route results of burst router-level topology can comprise more than multiple data
Storehouse, in addition to multiple backup databases corresponding with multiple primary databases.So when terminal is it is determined that there is invalid data stock
In case, database corresponding with invalid database in multiple backup databases can be accessed, is so obtained with
The whole content of first data, can more meet the needs of user.
In addition, the data of database may break down, then can not just ensure that database is all at any time can be with
Service is provided, for example, database breaks down, network failure, system jam, such as disk is full etc., it is caused
Database can not provide service, and in this case, terminal just can not the data of successful access first, the i.e. success rate of data access
It is relatively low.Even also there is a situation where to access failure unavoidably so accessing effective database.
Therefore, in the presence of backup database, the route results of burst router-level topology comprise more than the first data
Including multiple bursts where Database Lists, include the backup of the database where multiple bursts for including of the first data
Database Lists, terminal is in some or all of failed database in accessing at least one efficient database, then can be with
Thinking the database that has, there occurs failure.Now, terminal can is accessed in multiple backup databases with accessing miss data storehouse
Corresponding backup database, so as to obtain the first data, to improve the success rate for accessing data.
In addition, burst route is to calculate route results according to the routing rule in data access request and burst route
Afterwards, then by the route results of calculating terminal is fed back to, so that terminal goes to access the first data according to the route results of reception.
In the prior art, the routing rule of burst route is pre-set, once routing rule is changed, it is necessary to weight
During newly the routing rule programming after change to burst is route, it otherwise can not continue through burst route and data are conducted interviews.
In the embodiment of the present invention, burst route the routing rule of itself and can obtained by third party's program, and third party's program passes through
The mode of Run Script file is realized.In possible embodiment, JavaScript script languages are performed in java running environment
Speech, obtains script file.Wherein, third party's program is to enter the program of edlin according to burst rule, and burst rule is the first number
According to being divided into multiple burst rules according to which.
If burst rule is changed, such as newly increases burst rule, either abandon existing burst rule or
Improved in existing burst rule, accordingly routing rule is also just changed, and also just needs to update burst route
Routing rule.In the prior art, when needing to update routing rule, it is necessary to be burnt new routing rule again by fever writes
Record to all bursts and route, it is cumbersome.And in the embodiment of the present invention, third party's program can pass through Run Script file
Mode is realized, when routing rule is changed, it is only necessary to accordingly changes the code in script file, then Run Script text
Renewal routing rule can be achieved in part, more flexibly.In addition, in the embodiment of the present invention, script file can be disposed independently, can be with
Hot load and execution script file, without just-ahead-of-time compilation.So there is no need to by fever writes by new routing rule again
Burst route is burned onto, avoids operational cumbersome, is relatively easy to realize the extension of routing rule.
The implementation that burst route calculates route results according to data access request and third party's program is described below.
The data access request that burst route receiving terminal is sent, the request that can carry data access request access ginseng
Third party's program of number input setting, route results are calculated by third party's program, that is, more included by the first data
At least one Database Lists of individual burst, and at least one backup database list.Wherein, at least one Database Lists bag
Include the list of the burst included by the first data, and/or the list of the address of the database where burst.
Different types of data, corresponding burst rule are also different, then and corresponding routing rule is also different,
Corresponding script file is also different.In the embodiment of the present invention, different types of data can be embodied by logic table name,
Script file corresponding to so different logic table names is different, i.e., according to corresponding to logic table name can determine the data to be accessed
Routing rule.Wherein, logic table name can be used for the title of tables of data where identifying the first data, such as order table, Ke Yitong
Order form is crossed to represent.Order table t_order data volumes are very big, to do burst, can be split into t_ by date
Order201705, t_order201706, t_order201707 ... wait several sub- order tables, wherein, t_order is exactly to patrol
Collect table name, the table name with date suffix, such as t_order201705 and be properly termed as entity table name, entity table name can be understood as
The title of database where multiple bursts that first data include.When being conducted interviews to the first data, can determine first
The logic table name of first data, to determine routing rule corresponding to the first data by the logic table name, to further determine that
Multiple databases where multiple bursts included by one data.
In the embodiment of the present invention, data access request carries request and accesses parameter, and request, which accesses parameter, can include knot
Structure query language (Structured Query Language, SQL) sentence, burst field and logic table name, wherein, burst
Field is used for the access consideration of the data of identification access first, for example, the date.Continue by taking the example of the preceding paragraph as an example, burst field
Can be 201705,201706,201707 etc..
After burst route obtains request access parameter from data access request, it can be accessed first according to request in parameter
Logic table name determine corresponding script file, namely be to determine the routing rule to be used.After script file is determined, burst
Run Script file is route, and using the value for asking to access the burst field in parameter as the input parameter of script file, script
The output of file is exactly route results.For example, calculating order table t_order route results, determine to need by t_order first
The routing rule for the script file t_order.js to be used, then burst field date value is transferred to t_ as input parameter
Order.js, the result for performing t_order.js outputs is exactly route results.The route results include storehouse table information, i.e., both include
Data table information where first data, such as entity table name t_order201705, also including where t_order201705
Database information.
Further, the embodiment of the present invention considers that the data of magnanimity include various types of data, on the other hand, all kinds
Data carry out burst rules according to which, i.e., burst rule also include it is a variety of.It is so polytype when being stored on server
Multiple bursts of data.Terminal first has to obtain the burst rule of the first data, so as to edit with dividing before the first data are accessed
Script file corresponding to piece rule, then when terminal needs to access other data, it is necessary to update and other data
Script file corresponding to burst rule, is updated every time, cumbersome.
In consideration of it, in embodiments of the present invention, the record burst that terminal can be commonly used according to the data stored on server
Multiple script files corresponding to regular pre-edit, one of script file correspond to a kind of routing rule.Terminal can store
Multiple script files of pre-edit, when the data stored on to server conduct interviews, as long as script text corresponding to calling
Part.Accordingly even when server has newly increased the data of storage, as long as the burst rule of the data newly increased is constant, just it is not required to
Script file is updated, realizes the multiplexing of script file, avoids the operation of frequent edit script file.
Further, the burst route in the embodiment of the present invention can be realized more multiple by way of Run Script file
Miscellaneous routing rule.In the prior art, burst, which route stored routing rule, is realized by way of routing table, and is tied
The routing table storage organization of structure is difficult to meet that complicated routing rule is set.For example, in the situation of a variety of routing rules combination
Under, for example, the first data, using the period as the first result, are entered first according to date field burst on a time period according to certain field
Row Hash operation, most the first data carry out burst at last, and such routing rule is complex, and routing table is difficult to realize so
Rule.In the embodiment of the present invention, a script file can include routing rule more than two-stage or two-stage, or with above-mentioned
Exemplified by example, script file provided in an embodiment of the present invention can both include first according to the rule of period burst, again can be with
On the basis of according to period burst, the rule of Hash operation is carried out further according to certain field, i.e., in the embodiment of the present invention
Burst is route can realize complex routing rule by way of Run Script file, and application is more extensive.Certainly, one
It is only citing that individual script file, which includes two-stage routing rule, in possible embodiment, a script file can include three-level,
Routing rule even more than three-level.
Furthermore in the prior art, when terminal needs to access the first data, send data access request, burst route
The parameter carried in data access request, such as SQL statement are first parsed, burst field is determined whether further according to routing table and divides
Piece rule, if burst field and burst rule, then determine multiple bursts included by the first data.I.e. in prior art
In, burst route is firstly the need of access routing table, then calculates route results, and accessing routing table just needs to expend the time, so
The computational efficiency for having led to burst route is relatively low.And sometimes, burst is routed through the mode of routing table, and once calculated can
Route results can not be drawn, it is necessary to which the calculating carried out twice or more than twice can just draw route results.For example, refer to
Table 1, table 1 is the regular signal table of the burst of the first data, so that the rule according to the period carries out burst to the first data as an example.
Burst field, such as from date, the Close Date, burst is monthly done according to the burst field, configured in database generally such as
Shown in table 1, continuity over time, the configuration item of the table also needs to increase, if to access first data in May to July
Burst, it is obviously desirable to calculate the burst of first data in May, June and July respectively according to the routing rule in May, June and July,
Only it can not configure the routing rule by one.
The signal table of the burst rule of the data of table 1- first
| From date | Close Date | Table name |
| 20170501 | 20170531 | T201705 |
| 20170601 | 20170630 | T201706 |
| 20170701 | 20170731 | T201707 |
If the first data to be accessed exist in the T201705 and T201707 shown in table 1, then by existing
The mode of routing table in technology is realized, it is necessary to is calculated twice, and is required for accessing routing table, such burst route meter every time
Need to expend the time for accessing routing table when calculating route results, the computational efficiency for causing burst to route is relatively low.And of the invention real
Apply in example, burst route direct Run Script file and calculates route results, it is not necessary to access routing table, also save on and access road
By the time of table, so as to improve the computational efficiency of burst route.
After terminal receives the route results of burst route feedback, at least one database can be accessed according to route results
In part or all of database, obtain the first data.Sometimes user is only needed included by some bursts that the first data include
Data, then now terminal can access the partial database at least one database, without accessing whole numbers
According to storehouse, to save access time, data access efficiency is improved.Part or all of data at least one database of terminal access
During storehouse, directly it can be operated in part or all of database, for example, inquiry operation, modification operation, deletion action etc., certainly
These operations can be realized by SQL statement.
In the embodiment of the present invention, the routing rule mode that passes through third party's program, that is, script file of burst route
Realize,, can without routeing new routing rule programming to burst again through fever writes when routing rule changes
Various new routing rules are realized, are easy to extend routing rule, application is relatively broad, and script file need not be compiled in advance
Translate, can directly hot load and execution, implementation process is more convenient.
