Embodiment
Data interchange platform of the present invention is the platform software of being write by JAVA, is applicable to various server platforms, and uses the SAAS pattern, is once disposed by operator, is responsible for maintenance, and software user is rented the data exchange service of platform with Lease way.
Described data interchange platform is prior art, comprises with lower module:
Information management module: for receiving, process and send the information of described data interchange platform.
User management module: for managing the user profile of described data interchange platform, comprise that the user registers, the user profile inquiry, delete the user, revises user's associative operations such as user profile.
Device management module: be responsible for to use the maintenance of information of the mobile terminal device of described data interchange platform, comprise facility information storage, delete, search, the equipment associative operation such as modification.
The design of exchange middleware administration module: for managing the design of exchange middleware of described data interchange platform, comprise increase, deletion, data query conversion middleware, the design of exchange middleware that calls coupling carries out the conversion of specific data type.
Database: the data that the storage platform operation is required.
With the SaaS pattern, provide service: use the user of described data interchange platform without setting for this platform, the various hardware devices that the maintenance platform operation is required, these work are completed by the platform operation business.Platform operation business with the form of service to the use of user's open platform, after the user only need register, the data exchanging function just can usage platform provided.
Under the system of the many tenants based on SAAS, need to distinguish user and tenant's difference.
We are set as follows scene, the A of enterprise, in order to solve the exchanges data problem between employee's different terminals, has set up a data switching plane, and the employee is the user of the data interchange platform of the A of enterprise, data interchange platform is by the A of enterprise operation maintenance, many tenants of these right and wrong scene.Enterprise B has also been built an identical data interchange platform afterwards.Problem has just been come, and two data switching plane functions are identical, can only with a data switching plane, substitute? many tenants system addresses this problem.In many tenants system, the A of enterprise before and enterprise B, without the data interchange platform of building and safeguard oneself, are built and are safeguarded by data interchange platform operator.The A of enterprise and enterprise B are rented the data exchange service that the platform operation business provides, and here, the A of enterprise and enterprise B are the tenants, and the employee in two enterprises is the user.
The problem that exists the tenant to isolate under many tenants system, because what a plurality of tenants used is a platform, suppose to exist in two a plurality of tenants the terminal of same type, if do not carry out tenant's isolation, which should information send to so? the present invention isolates tenant data by the mode of prior art database cutting, and detailed process is as follows:
In database, for each registration tenant creates a schema, a schema is exactly the set of database table, view.Each tenant's user profile and terminal equipment information etc. all leave in schema separately, for tenant and schema set up mapping relations.For by tenant under the request identification terminal, need to there is the public sheet collection that the tenant has nothing to do to deposit tenant's information and some mapping relations tables.The public sheet collection should comprise tenant's information table at least, terminal equipment ID and tenant ID mapping relations table.Wherein, all terminal equipment ID of all tenants and affiliated tenant's ID thereof in the store data switching plane in terminal equipment ID and tenant ID mapping relations table.
Below by a data exchange process explanation specific embodiment of the invention step.
A kind of isomeric data of mobile internet based on SAAS pattern switching method, comprise the following steps: the mobile terminal A of transmit leg crosses mobile Internet by information exchange and sends to data interchange platform, data interchange platform is used a kind of standard data type to be intermediary, first convert the data type A of transmit leg to standard data type, again standard data type is converted to the data type B that recipient's mobile terminal B can identify, finally data type B is sent to recipient's mobile terminal B by mobile Internet.
Reach step by step specific embodiment as follows:
S1. the user is by the end message administration module, and input receiving equipment information, send data message, and the end message administration module sends to data interchange platform by the Internet by information.For example certain user need to send to the address list in mobile phone another user, and the user arranges the identifying information of receiving equipment in the end message administration module, can be unique EIC equipment identification code, can be also the possessory user name of equipment, tenant's name oil (gas) filling device name.Needing simultaneously to arrange the data format of address list, is for example CSV.After setting, the user selects to send address list, and the end message administration module sends to data interchange platform by transmitting terminal and receiving device information and data message.
S2. the listening port of data interchange platform is received data exchange request, according to predefined request form, obtains receiving equipment information and needs the data message exchanged.As adopt the JSON formal definition, can { senddev:1234567, revdev:7654321, datatype:csv}.Data interchange platform can be by the JSON Reading and writing instrument from parsing information needed easily the data of JSON form.
S3. after obtaining transmitting terminal and receiving device information, by facility information, search terminal equipment in database, due to the terminal equipment One's name is legion of access platform, use common traversal search performance excessively poor, here adopt the prior art Sherwood algorithm to carry out fast finding, specific as follows:
Sherwood algorithm is a kind of of probabilistic algorithm, and its basic thought is: establishing A is a deterministic algorithm, and be designated as t required computing time when its input example is x
A(x).If the input size that Xn is algorithm A is example all of n, when the input size of problem was n, algorithm A was required average time:
This obviously can not get rid of and exists x ∈ Xn to make
Possibility.Therefore wish to obtain a probabilistic algorithm B, making input size to problem is that each example of n all has:
In practice, the major key in the terminal equipment information table is deposited in array, during retrieval, use Sherwood algorithm to search matched termination equipment to the major key array.
If there is not matched termination equipment, return to corresponding error message.If exist, the terminal equipment of concentrating by public sheet and tenant's relation mapping table further obtain tenant ID under transmitting terminal and receiving device, and comparison.If two equipment do not belong to same tenant, do not allow swap data, return to error message.Otherwise, by the mapping relations between tenant and schema, determine concrete schema.Mapping relations can simply be set to the title that tenant ID is schema.As tenant ID, be tenent1, corresponding schema tenent1 by name.
S4. by the receiving terminal apparatus ID that obtains and tenant's schema name, using it as the parameter call storing process, obtain the data format that receiving terminal apparatus is supported.Under many tenants system, list structure in each tenant schema is identical, the content difference, and the sql statement of searching the data format that terminal equipment supports by terminal equipment ID is basically identical, but the schema difference under table, need add that the schema name is distinguished before the table name in the sql statement.Use storing process can before the sql statement is carried out, dynamically determine the schema name.
S5. carry out data transaction.By the unified data format of data interchange platform, as intermediary, by twice conversion, by the transmitting terminal Data Format Transform, be the receiving terminal data format, as shown in Figure 2.In practice, according to data type, call related converting method by design of exchange middleware and complete conversion.Detailed process is as follows: establish the address list that transmitting terminal need to send the CSV form, receiving terminal is supported the address list form of excel, and the unified XML that uses of data interchange platform is as standard data type.Two mapping sets in design of exchange middleware DataExchange class, have been maintained, as Map, be respectively the conversion method mapping set xmlto of general data type to the conversion method mapping set toxml of standard data type and standard data type to the general data type.First by toxml, search the method that CSV turns XML, the CSV address list is changed into to the XML address list, more in like manner XML is changed into to the excel address list.
After converting, the receiving terminal information according to finding before, send to receiving terminal by the excel address list, receives and point out the user by the end message administration module of receiving terminal.
Wherein, the data that mean with described standard data type can convert other all data types that described data interchange platform is supported to, otherwise, can also convert standard data type to the data of the data types to express of any described data interchange platform support.
