4, Content Management System
Content Management System mainly comprises Content Management main frame and database host, and the Content Management main frame is used to preserve content object, and as previously mentioned, content object is kept in the file system of Content Management main frame with the form of unique file.Database host is used to preserve structured messages such as the attribute information, user profile, authority, life cycle of content object, and the service of database aspect is provided to the content management host.Usually, the Content Management main frame also can be called explorer, and database host also can be called index server.
Need to prove, when the physical pathway of query contents object, can only pass through Content Management host access database host, be specially: the Content Management main frame sends query statement to database host, the physical pathway that database host is searched content object according to the query statement that receives sends it to the Content Management main frame.
Below in conjunction with accompanying drawing the present invention being obtained the method for content object, the method for preserving content object and the embodiment of corresponding system is described.
With reference to figure 3, wherein be a kind of structural representation that is used to preserve or obtain the system of content object of the present invention.As shown in Figure 3, described system comprises at least: operation system 301, uniform client 302, dns server 303 and service host 304 (promptly described herein first service host).
When content object being preserved operation, operation system 301 extracts traffic ID from the metadata of content object to be preserved, submit solicited message to uniform client 302 then, described request information comprises: described traffic ID and described content object, uniform client 302 is according to the assembling of the traffic ID in described request information domain name, domain name is sent to dns server 303 resolves, obtain the IP address, send to service host 304 according to the IP address again and preserve request message, described preservation request message carries described traffic ID and described content object, service host 304 receives described content and preserves request message, preserves described content object.
Need to prove, in the above-described embodiment, described content object is included in the content object that operation system 301 is managed business and produced in the request process, and/or the content object from the user that receives of operation system 301 (as: content object of submitting to through user terminal of not preserving, or need the content object preserved again after the user's modification).
When content object being obtained operation, operation system 301 extracts traffic ID from the metadata that the user submits to, submit solicited message to uniform client 302 then, described request information comprises: the area code of described traffic ID and described user region, uniform client 302 is used for assembling first domain name according to the area code of described traffic ID or described user region, described first domain name is sent to dns server 303 resolves, obtain an IP address, and, obtain the content object of described traffic ID correspondence according to a described IP address access services main frame 304.
When content object being preserved or obtaining operation, operation system 301 extracts the sign of described content object from the metadata of content object, send it to uniform client 302, and in embodiments of the present invention, we are called traffic ID with this sign.Particularly, traffic ID comprises four territories at least, is respectively: attributed region code, content object types, date created and business serial number.Respectively these four territories are specifically described below:
1, attributed region code: the attributed region code is the area code of the attributed region of content object, is used for the attributed region of marked content object.
Wherein, area code is used for the title of tab area center or branch, is normal data, has uniqueness.With the Construction Bank is example, " The Ministry of Information Industry of the People's Republic of China, MOII is about the bulletin of China Internet network domain name system " of reference information Estate Division in February, 2006 issue, for head office of Construction Bank, one-level branch and be directly under the jurisdiction of secondary and distributed unique area code in lines, specific as follows:
Zh-head office, ah-Anhui Province branch, bj-Beijing branch, cq-Chongqing City branch, dl-Dalian branch, fj-Fujian Province branch, gd-Guangdong Province branch, gs-Gansu Branch, gx-Guangxi Zhuang Autonomous Region branch, gu-Guizhou Province branch, ha-Henan Province branch, hb-Hubei Province branch, he-Hebei province branch, hi-Hainan Province branch, hl-Heilongjiang Province branch, hn-Hunan Province branch, jl-Jilin Province branch, js-Jiangsu Province branch, jx-Jiangxi Province branch, ln-Liaoning Province branch, nb-Ningbo branch, nm-Inner Mongolia Autonomous Region branch, nx-Ningxia Hui Autonomous Region branch, qd-Qingdao branch, qh-Qinghai Province branch, sa-Three Gorges branch, sc-Sichuan Province branch, sd-Shandong Province branch, sh-Shanghai City branch, sn-Shaanxi Province branch, the su-Suzhou Branch, sx-Shanxi Province branch, sz-Shenzhen branch, tj-Tianjin branch, branch of xj-Xinjiang Uygur autonomous region, xm-Xiamen branch, branch of xz-Tibet Autonomous Region, yn-Yunnan Province branch, zj-Zhejiang Province branch.
2, content object types: content object types is the Sort Code of content object, is mainly used in the affiliated operation system that characterizes content object, storage policy (as: concentrate and be kept at head office or distributed and saved in branch), Lifecycle Policies (as: online pot-life, off-line pot-life etc.).Wherein, the storage policy of content object and Lifecycle Policies are determined by business demand.
With the Construction Bank is example, and public credit system has the content object of two types of " clpm_doc1 " and " clpm_doc2 ", and wherein, " clpm_doc1 " class content object is concentrated and is kept at head office, and " clpm_doc2 " class content object distributed and saved is in branch; There is the content object of two types of " pmis_doc1 " and " pmis_doc2 " in individual loan system, and both all disperse to be kept at branch, but " pmis_doc1 " class content object needs to destroy after preserving 15 years, and " pmis_doc2 " class content object needs permanent the preservation.
3, date created: date created is the date that operation system produces content object, rather than Content Management System is preserved the date of content object.Need to prove that in the practical operation, these two kinds of dates are likely inconsistent, because the system of some subsequent supervision type is saved in the Content Management System finishing just will conclude the business after several days content objects such as voucher of generation of transaction.
4, business serial number: business serial number is that operation system is the serial number that distributes at the content object that the business process of carrying out produces, and business serial number is unique in operation system.
Need to prove, in other embodiments of the invention, traffic ID can also have other composition form, for example: replace a territory of above-mentioned traffic ID or the information in a plurality of territories with other attribute informations that can identify content object, perhaps remove above-mentioned four overseas, traffic ID can also comprise other territory.
In embodiments of the present invention, introduce dns server, the part territory of traffic ID is shone upon as domain name and service host.Be example with the Construction Bank below, the service host domain name be introduced:
" the China Internet network domain name supervising way " of reference information Estate Division in November, 2004 promulgation, and " The Ministry of Information Industry of the People's Republic of China, MOII is about the bulletin of China Internet network domain name system " of in February, 2006 issue, reality in conjunction with Construction Bank, for Content Management System has distributed three grades of domain names " ecm.ccb.com.cn ", and further according to concrete purposes be in the system host assignment the level Four domain name, wherein, the level Four domain name of service host is " in.ecm.ccb.com.cn ", simultaneously, also distributed two cover subdomain names for service host: Pyatyi domain name and six grades of domain names, both all belong to level Four domain name " in.ecm.ccb.com.cn ".
Self domain name that it should be noted that service host represents with the Pyatyi domain name, and the level V subdomain in self domain name is the area code of service host affiliated area.
Particularly, in the embodiment that preserves content object, uniform client 302 is specially according to the domain name of traffic ID assembling service host: the content object types in the traffic ID and attributed region code respectively as level V subdomain and the 6th grade of subdomain assembling domain name (this domain name is six grades of domain names), are used to represent the domain name of the service host of content object attributed region.
In obtaining the embodiment of content object, uniform client 302 comprises according to first domain name of the area code of traffic ID or user region assembling service host: the area code of user region is assembled first domain name (this first domain name is the Pyatyi domain name) as the level V subdomain, be used for representing the domain name of the service host of user region; Perhaps content object types in the traffic ID and attributed region code are assembled first domain name (this first domain name is six grades of domain names) as level V subdomain and the 6th grade of subdomain respectively, be used to represent the domain name of the service host of content object attributed region.For example: the content object A in the clpm system, its content object types is " clpm_doc2 " (distributed and saved is in branch), the attributed region code is " hn ", the area code of user region is " hb ", and then the service host domain name of uniform client 302 assemblings is: Pyatyi domain name " hb.in.ecm.ccb.com.cn " or six grades of domain names " hn.clpm_doc2.in.ecm.ccb.com.cn ".
From the above, in embodiments of the present invention, when content object is preserved, from the metadata of content object, extract traffic ID, and according to described traffic ID assembling domain name, resolve the domain name assemble out by dns server obtaining the address of service host, and then realize preservation content object; When obtaining content object, from the metadata that the user submits to, extract traffic ID, and assemble first domain name according to the area code of described traffic ID or user region, resolve first domain name assemble out by dns server to obtain the address of service host, and then obtain the content object of described traffic ID correspondence, realized the unified resource location, by domain name mapping, uniform client and service host can navigate to the service host of content object storage area apace, need not distributed and saved concentrated in the positional information of each regional all the elements object and be kept in the database host in a zone, thereby in the process of preserving and obtain content object, do not need database is carried out remote operation, guarantee safeness of Data Bank, improved the resource location efficiency.In addition, the embodiment of the invention adopts the mode of access services main frame to obtain content object, and the possibility of setting up CACHE (high-speed cache) mechanism for the strange land content object is provided.
Below in conjunction with Fig. 4 and Fig. 5 the embodiment of uniform client is described.
With reference to figure 4, wherein be the structural representation of the embodiment 1 of the uniform client 302 among Fig. 3.As shown in Figure 4, uniform client 302 comprises at least:
The 3rd receiver module 3021 is used to receive the solicited message that operation system 301 is submitted to, and described request information comprises: the content object of traffic ID and described traffic ID correspondence;
The 3rd domain name module 3022 is used for the described traffic ID assembling domain name of the solicited message that receives according to the 3rd receiver module 3021, and domain name is committed to dns server 303 resolves;
The 3rd receiver module 3021 also is used to receive dns server 303 and resolves the IP address that obtains;
Preserve request module 3023, the described IP address that is used for receiving according to the 3rd receiver module 3021 sends to service host 304 preserves request message, and described preservation request message carries described traffic ID and described content object.
With reference to figure 5, wherein be the structural representation of the embodiment 2 of the uniform client 302 among Fig. 3.As shown in Figure 5, uniform client 302 comprises at least:
The first domain name module 3025 is used for the traffic ID of the solicited message that receives according to first receiver module 3024 or the area code of user region and assembles first domain name, and described first domain name is sent to dns server 303 resolves;
In other execution modes of the present invention, uniform client 302 can also comprise and represent module that the content object that is used for receiving represents to described user.
Since Content Management towards the user be dispersed in each zone, (with the Construction Bank is example and the actual distribution situation of content object is also different, the concentrated head office that is kept at that has, the distributed and saved that has is in branch), so the situation of the trans-regional accessed content object of user is comparatively common.In the prior art, adopt the mode of the Content Management main frame at direct accessed content object place to obtain content object, thereby when the same content object of the repeatedly trans-regional visit of user of the same area, just need repeatedly this content object to be transferred to the user region from the storage area, backbone network pressure is big, and the response time is long.
In order to alleviate network pressure, to promote user experience, the embodiment of the invention can provide CACHE mechanism for trans-regional visit.Particularly, obtain in the scene of content object the user, at first service host is determined in customer-centric, that is: no matter where content object is kept at, also no matter where operation system is deployed in, the access request that the user obtains content object is all submitted to the service host of user region.Embody and to be specially in embodiments of the present invention: when obtaining content object, the Pyatyi domain name of the area code assembling service host of the user region in the solicited message that the first domain name module 3025 receives according to first receiver module 3024.With the Construction Bank is example, the operator in Hubei requires to visit the content object that belongs to the Hunan, so, its access request need be submitted to the service host (domain name of this service host is " hb.in.ecm.ccb.com.cn ") of one's respective area, rather than submits to the service host (domain name of this service host is " hn.in.ecm.ccb.com.cn ") in Hunan.
Certainly, obtain among other embodiment of content object in the present invention, also can not utilize CACHE mechanism, service host is determined in i.e. not customer-centric, and directly be that service host is determined at the center with the content object: six grades of domain names of attributed region code in the described traffic ID in the solicited message that the first domain name module 3025 receives according to first receiver module 3024 and content object types assembling service host, and be sent to dns server and resolve.
Need to prove, obtain among the embodiment of content object in the present invention, the principle of being followed when the 3rd domain name module 3025 is set up first domain name (is determined service host as customer-centric, or be that service host is determined at the center with the content object) can be pre-configured in the system, also can in practical operation, select temporarily.
Need to prove, uniform client 302 can realize (describing in conjunction with Fig. 4) embodiment 1 and (describing in conjunction with Fig. 5) embodiment 2 described functions simultaneously, be that uniform client 302 can comprise the whole modules among Fig. 4 and Fig. 5, and, wherein the function of the 3rd receiver module 3021 and first receiver module 3024 can use a module to realize, the function of the 3rd domain name module 3022 and the first domain name module 3025 can use a module to realize.
Need to prove, the difference of the storage policy that adopts according to reality, the attributed region of content object may be different with the actual storage area of content object, in order to address this problem, mechanism or the wide area name analysis rule that a plurality of domain names is corresponded to an IP address is set in dns server usually, six grades of domain names that will include the attributed region code are mapped on the IP address of service host of actual storage area of this content object, particularly, with the Construction Bank is example: in the clpm system, type is concentrated for the content object of " clpm_doc1 " and is kept at head office, type be " clpm_doc2 " the content object distributed and saved the branch, content object with Hubei branch is an example, " hb.clpm_doc1.in.ecm.ccb.com.cn " points to same address with " zh.in.ecm.ccb.com.cn " on dns server, and " hb.clpm_doc2.in.ecm.ccb.com.cn " then points to same address with " hb.in.ecm.ccb.com.cn ".
Below in conjunction with Fig. 6-Fig. 8 the embodiment of service host is described.
With reference to figure 6, wherein be the structural representation of the embodiment 1 of the service host 304 among Fig. 3.As shown in Figure 6, service host 304 comprises at least:
