Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with the accompanying drawing each reality to the present invention
The mode of executing is explained in detail.But, it will be understood by those skilled in the art that in each embodiment of the present invention,
In order to make reader be more fully understood that, the application proposes many ins and outs.But, even if there is no these ins and outs and base
Many variations and amendment in following embodiment, it is also possible to realize the application each claim technical side required for protection
Case.
First embodiment of the present invention relates to the data access method of a kind of multiple database.Idiographic flow as it is shown in figure 1,
The present embodiment specifically includes:
In step 101, cloud server judges whether that receiving the domain name access from client asks, if high in the clouds clothes
The domain name access that business device receives from client is asked, then enter step 102, otherwise, repeat this step.Concrete
Saying, domain name is to be climbed up the address of network by client, and popular says, domain name is equivalent to the house number of one family, its
Other people are easily found " people " to be looked for by this number.The client that user uses can be computer, mobile phone or flat board
Computer etc..
Cloud server, it is first determined whether receive the domain name access request that client sends, i.e. needs to access as user
During certain page, will input a domain name in the position of web page address, the electronic equipment such as computer, mobile phone can send one automatically
Domain name access asks cloud server.If cloud server does not receive domain name access request, this cloud server meeting one
The access request that straight wait is new.
In step 102, cloud server, according to the internetworking Protocol IP address of client, detects residing for this client
The band of position.Specifically, internetworking Protocol IP address is a kind of unified address format that IP agreement provides, and IP agreement is
Each network on the Internet and each station terminal one logical address of distribution, shield the difference of physical address with this.Logical
Saying of custom, each terminal number that IP address is used on the Internet, terminal here can be the electronics such as computer, mobile phone
Equipment.The terminal being numbered by these, just can ensure that normal communication.Internetworking Protocol IP address carries position
The information in region, cloud server views the lane place of this client by detection client internetworking Protocol IP address
Territory, thus reasonably distribute.
Such as, a computer being in the U.S., user have input webpage to be checked in the position of browser address bar
The domain name addresses of address, i.e. this website.This computer can send domain name access request from trend cloud server, works as cloud server
Receive the request of this domain name access, the request of this domain name access can be resolved and checks between the net sending domain name access request computer
Interconnection protocol IP address, by the information carried on this IP address, it is possible to determine that this computer location region is the U.S..
In step 103, domain name access request, according to the band of position detected, is forwarded to and client by cloud server
It is in the proxy server of co-located region.Specifically, proxy server is a kind of special network service, it is allowed to one
The network terminal (generally client) is served another network terminal (generally server) by this and is carried out non-immediate
Connect.The function of proxy server is exactly that agency network user goes to obtain the network information, and a proxy server is the most permissible
Being interpreted as the terminal of the network information, it can significantly improve surfing and the efficiency of network data, and for being positioned at phase
The effect of the proxy server in co-located region, this raising speed and efficiency is more very.Therefore, cloud server can be according to inspection
Measure the band of position of the client sending domain name access request, be that this client finds one in the identical or nearest band of position
Platform proxy server, is used for acting on behalf of this client and quickly obtains networking information.
In step 104, proxy server judges whether the domain name access received request is read-only operation type, if receiving
To domain name access request be read-only operation type, then enter step 105, otherwise, enter step 106.Specifically, in advance will
The access request of each domain name is divided into read operation type and write operation type.Such as, territory in the domain name access request of client
Webpage associated by Ming is the webpage of read-only type, and user can only browse the information of webpage, and cannot add or revise net
The content of page, then the access request of this type of domain name is just divided into read operation type；If domain name access can be asked by client
Webpage associated by middle domain name carries out interpolation or the amendment of content, as inputted account, password etc., then by the domain name of this type of client
Access request is divided into write operation type.
It is in the proxy server of co-located region, according to the territory of client with the client initiating domain name access request
Name access request, the action type of detection domain name access request.Wherein, for the domain name of read-only operation type Yu write operation type
Access request, performs different subsequent operations.Domain name access for read-only operation type is asked, and client will not be to access
The content of domain name addresses make any amendment, the speed of response is a index the most important；For write operation type
Domain name access is asked, and client needs the content of the domain name addresses accessed is made amendment, and this will further relate to data
Stationary problem, it is ensured that the robustness of synchronization becomes more crucial factor.
In step 105, proxy server is by the read operation of the local data base to same position region, customer in response end
Domain name access request.Specifically, in data base, preserve in the access information that client needs proxy server to obtain
Hold, in multidatabase system, generally comprise a MDL and multiple from data base.In the present embodiment, master data
Storehouse allows read operation and write operation, only allows read operation from data base.It is to say, all operation classes relevant with write operation
Type, is all carried out on MDL；And read operation type, then shared and carried out from data base, so can be greatly improved
The efficiency read.In general internet, applications, the read operation type of client and the ratio of write operation type are about 10:
1, say, that substantial amounts of data manipulation type is to concentrate in the action type of reading.
In this step, reason server is initiated to the application programming interface API server being in same position region
The read operation request of data base；The local data base being in same position region, according to read operation request, is carried out by API server
Read operation.
Specifically, application programming interface API is one group of definition, program and the set of agreement, real by api interface
Being in communication with each other between existing computer.Application programming interface API is also middleware simultaneously, provides number for various different platforms
According to sharing.Application programming interface API is the mode of a kind of real-time acquisition data, is also the most best mode.If it is objective

API server will not carry out read operation to strange land data base, ensures data transmission meeting by calling application programming interface API
Safer.
In step 106, proxy server is by the read-write operation to MDL, and the domain name access of customer in response end please
Ask.Specifically, the read-write operation of the proxy server API server initiation data base to region, MDL position please
Ask；The API server in region, MDL position, according to read-write operation request, is written and read operation to MDL.
If it is to say, the domain name access request of client is write operation requests, then needed by master data region
API server MDL is carried out write operation, proxy server relates to this number for the write operation type of data base
According to the change of content in storehouse, the robustness problem of this safety having related to data-base content and synchronization, by master data institute
API server in region to MDL in the change of content, it is to avoid the API server write operation to strange land data base,
Guarantee data transmission security.
Such as, a client request being positioned at the U.S. accesses the domain name belonging to write operation type, then a cloud service
Device can first find and be in the U.S. agent server of same geographic location with this client, and proxy server passes through MDL institute
The operation that MDL is write by the API server in region, if the geographical position of this MDL is positioned at China, then acts on behalf of
Server will carry out write operation by the API server of China to the MDL in China.
In step 107, the data in MDL be synchronized to termly region, each proxy server position from number
According to storehouse.Specifically, proxy server, for the write operation in MDL, can change the content in MDL, but this
The content of a little changes can't see from data base, is regularly synchronized to each proxy server by data in MDL
Region, position from data base so that keep from data base and content consistent in MDL, it is achieved data same
Step, and by MDL to from the synchronization of database data, it is ensured that the robustness of synchronization.
Relative to prior art, cloud server, please by domain name access according to the client domain name access request received
The proxy server being sent to same position is asked to be written and read operation, by the proxy server local number to same position region
Read operation according to storehouse, it is ensured that the response speed of data base's read-only operation.By proxy server, the read-write of MDL is grasped
Make and MDL be regularly synchronized to region, each proxy server position from data base, it is ensured that database synchronization
Robustness.
