Thus, the various sequences in the specification and drawings are for the purpose of describing certain embodiments only and are not intended to imply a required sequence unless otherwise indicated where such sequence must be followed.
The numbering of the components as such, e.g., "first", "second", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning. The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).
Referring to fig. 1, the present invention provides a data resource sharing platform 10, which includes a directory system 11, a directory database 12, and a switching transmission system 13.
When sharing data resources, the inventory must be completed first. The directory system 11 is configured to define a basic attribute and an information index of a resource directory according to the obtained data resource, where the definition of the basic attribute of the resource directory includes: the definition of the information index comprises the following attributes such as directory name, table name, update period and the like: field name, field type, field length, whether nullable, comparable, and shared type. Then, the directory system 11 generates a resource directory and metadata thereof according to the defined basic attributes and information indexes, and the issued resource directory can be stored in the directory database 12. The metadata includes index items for describing the resource directory, and each index item can be regarded as an attribute of the metadata. Fig. 2 shows metadata, in which information such as a resource directory name, a resource directory table name, and a resource directory abstract, and index items for describing the resource directory are displayed. It can be seen that the resource directory corresponding to the metadata in fig. 2 is user information, which is described by a user name, a gender, a birth date, an identification number, and a registration date. For example, the resource directory includes ten thousand pieces of user information, each having the five contents of a user name, a gender, a birth date, an identification number, and a registration date. The directory system 11 further establishes a data table associated with the resource directory according to the metadata, and the attributes of the data table correspond to the attributes of the metadata one to one. For example, in the data table shown in fig. 3, each row in the data table is an attribute of the data table, each attribute corresponds to each index item of the metadata in fig. 2, the data table may be stored in the resource provider 20 (described below), and in addition, a corresponding one of the above index items may be designated as a table primary key, for example, in fig. 3, a user name is designated as a primary key of the table. Meanwhile, the directory system 11 issues part of or all of the index items in the metadata as query conditions.
After the cataloging is completed, the data resource sharing platform 10 performs service authorization. The service authorization refers to acquiring all or part of index items of a specified resource directory, the resource using end 30 needs to acquire data resources of the specified resource directory, and needs to apply for authorization for resource directory usage, and resource acquisition can be performed only through resource directory authorization, and the data range of resource acquisition is limited to the authorized resource directory and the index items authorized for usage under the directory (from the perspective of the resource using end 30, it is a query condition). Specifically, based on the resource application request of the resource using end 30, the resource application authority of the resource using end 30 is verified, the resource application request may be first transmitted to the switching transmission system 13, and then submitted to the directory system 11 by the switching transmission system 13, where the resource application request includes the selected query conditions from the issued query conditions, for example, when issuing the query conditions, each query condition is checkable, the resource using end 30 can select the query condition (i.e. the index item) to be used subsequently by checking the query condition, in some embodiments, the resource application request further includes an identity representing the identity of the resource user 30, so that verifying the resource application authority of the resource user 30 includes: the authority of the resource consumer 30 is verified based on the identity, if the resource application authority is verified, the directory system 11 constructs a service interface including the selected query condition. For example, when the data resource sharing platform 10 is applied to a government system, a civil department wants to obtain three index items (query conditions) of name, gender and marital information of a user, and after the identity of the famous civil department is verified by the data resource sharing platform 10, the civil department is determined to have the authority to use the three query conditions, so that a service interface is provided for the civil department, and if the civil department also wants to use the identity card number as the query condition and does not have the authority to use the identity card number as the query condition, the data resource sharing platform 10 does not provide the service interface for the civil department.
The data resource sharing platform 10 automatically constructs a service interface after authorization is passed according to the set index items as query conditions for acquiring the service, thereby reducing the data use threshold.
After providing the service interface, the directory system 11 also verifies the resource obtaining authority of the resource using end 30 based on the resource obtaining request of the resource using end 30 for the service interface. Specifically, the resource using end 30 may transmit the resource obtaining request to a service interface provided by the switching transmission system 13, and the switching transmission system 13 uploads the resource obtaining request to the directory system 11 for performing the authority verification. For example, after the service interface is constructed, the directory system 11 provides a first authorization code to the resource using end 30 through the exchanging and transmitting system 13, and the data resource sharing platform 10 requires that the resource obtaining request includes a second authorization code for authorization verification, the directory system 11 compares the first authorization code with the second authorization code, verifies the resource obtaining authorization of the resource using end 30 according to the comparison result, and if the two authorization codes are the same, the resource using end 30 is allowed to obtain data, that is, the directory system 11 calls a corresponding data table according to the resource obtaining request. In some embodiments, the data table further converts the data table into a data set according to a standard specification, and then further performs data filtering: and filtering the data table exceeding the maximum limit of the number of rows of the data set, and transmitting the filtered data table to the resource using end 30 for use through the exchange transmission system 13, so as to finish the transmission of the data resource.
To better illustrate the work flow of the data resource sharing platform 10, fig. 1 is taken as an example for description.
In fig. 1, in addition to the data resource sharing platform 10, the data resource sharing platform further includes a resource providing end 20 and a resource using end 30, where the resource providing end 20 is used to provide resources, and the resource using end 30 requests resources from the directory system 11.
The resource provider 20 includes a pre-repository 22 storing data resources, which may be structured data, unstructured data or semi-structured data, and a first pre-switching system 21, and the data resources in the pre-repository 22 may be transmitted to the switching transmission system 13 through the first pre-switching system 21. The catalog system 11 completes the catalog making process according to the acquired data resources, and in the catalog making process, the established data table is transmitted to the pre-library 22 through the exchange transmission system 13 and the first pre-exchange system 21.
The resource user terminal 30 includes a service application system 32 and a second head exchange system 31. The service application system 32 is used for constructing a resource application request and a resource acquisition request, the constructed resource application request and resource acquisition request are both transmitted to the exchange transmission system 13 through the second pre-exchange system 31, and then are submitted to the directory system 11 by the exchange transmission system 13 for corresponding authority verification, if the authority verification fails, the directory system 11 notifies the resource using end 30 that the authority does not pass, if the resource application authority passes, the directory system 11 constructs a corresponding service interface and provides the service interface to the resource using end 30 through the exchange transmission system 13, the service application system 32 at this time also constructs an participation request according to a participation format, the participation request can be packaged with the resource acquisition request, if further the resource acquisition authority passes, the exchange transmission system 13 routes the request to the first pre-exchange system 21 of the resource providing end 20, the first pre-exchange system 21 processes the resource acquisition request, and returning the data resource, wherein the data resource is directly returned through the transmission channel, and the second front-end switching system 31 of the resource user 30 returns the data to the service application system 32 according to the request mode (such as synchronous/asynchronous) of the service application system 32.
Specifically, in an application scenario, the data resource sharing platform 10 may be used in a government affairs system, the resource provider 20 is a mechanism (e.g., a statistical department) responsible for collecting various types of information of residents, and the various types of information of residents may include identity information, academic information, marital information, skill certificate information, and the like. The resource usage terminals 30 may be departments that perform government functions, such as education departments, transportation departments, and civil administration departments, and different authorities are given according to the respective departments. For example, the education department may search for residents with the academic information as a search condition, and the civil administration department may search for residents with the marital information as a search condition.
Referring to fig. 4, the present invention further provides a data resource sharing method, including the steps of:
and step 100, defining basic attributes and information indexes of the resource catalog according to the acquired data resources. Wherein, the definition of the basic attribute of the resource directory comprises: the definition of the information index comprises the following attributes such as directory name, table name, update period and the like: field name, field type, field length, whether nullable, comparable, and shared type.
And 200, generating a resource directory and metadata thereof according to the basic attribute and the information index. The metadata includes an index entry for describing the resource directory.
Each index item may be regarded as an attribute of metadata. Fig. 2 shows metadata, in which information such as a resource directory name, a resource directory table name, and a resource directory abstract, and index items for describing the resource directory are displayed. It can be seen that the resource directory corresponding to the metadata in fig. 2 is user information, which is described by a user name, a gender, a birth date, an identification number, and a registration date. For example, the resource directory includes ten thousand pieces of user information, each having the five contents of a user name, a gender, a birth date, an identification number, and a registration date.
And step 300, establishing a data table associated with the resource directory according to the metadata. The attributes of the data table correspond to the attributes of the metadata one to one.
For example, in the data table shown in fig. 3, each row in the data table is an attribute of the data table, each attribute corresponds to each index item of the metadata in fig. 2, the data table may be stored in the resource provider 20 (described below), and in addition, a corresponding one of the above index items may be designated as a table primary key, for example, in fig. 3, a user name is designated as a primary key of the table.
And 400, issuing part of index items or all index items in the metadata as query conditions.
Step 500 is a service authorization process, where the service authorization refers to obtaining all or part of index items of a specified resource directory, and the resource using end 30 needs to obtain data resources of the specified resource directory, and needs to apply for authorization for use of the resource directory, and resource obtaining can be performed only through authorization of the resource directory, and a data range of resource obtaining is limited to the authorized resource directory and the index items authorized for use under the directory. The resource application request includes selected query conditions in the issued query conditions, for example, when the query conditions are issued, each query condition is checkable, the resource using end 30 can select the query conditions (i.e., the index items) for subsequent use by checking the query conditions, and in some embodiments, the resource application request further includes an identity representing the identity of the resource using end 30, so that the resource application permission for verifying the resource using end 30 includes verifying the permission of the resource using end 30 according to the identity.
And 600, constructing a service interface comprising the selected query condition. For example, when the data resource sharing platform 10 is applied to a government system, a civil department wants to obtain three index items (query conditions) of name, gender and marital information of a user, and after the identity of the famous civil department is verified by the data resource sharing platform 10, the civil department is determined to have the authority to use the three query conditions, so that a service interface is provided for the civil department, and if the civil department also wants to use the identity card number as the query condition and does not have the authority to use the identity card number as the query condition, the data resource sharing platform 10 does not provide the service interface for the civil department.
For example, after the service interface is constructed, the data resource sharing platform 10 provides a first authorization code to the resource using end 30, and the data resource sharing platform 10 requires that the resource obtaining request includes a second authorization code for authorization verification, the data resource sharing platform 10 compares the first authorization code with the second authorization code, verifies the resource obtaining authorization of the resource using end 30 according to the comparison result, and if the two authorization codes are the same, the resource obtaining authorization verification is passed.
And step 800, calling a corresponding data table according to the resource acquisition request. In some embodiments, the data table further converts the data table into a data set according to a standard specification, and then further performs data filtering: and filtering the data table exceeding the maximum limit of the line number of the data set, and transmitting the filtered data table to the resource using end 30 for use, so as to finish the transmission of the data resource.
The data resource sharing platform of the embodiment automatically constructs the service interface after the authorization passes according to the set index item serving as the query condition for acquiring the service, so that the data use threshold is reduced, the service interface does not need to be separately developed according to different resource use ends, the development workload is small, the maintenance cost is low, and in addition, the resource directory and the fields in the service interface are in a one-to-one correspondence relationship, so that the unified management of the resource directory and the data resources is facilitated.
The present invention has been described in terms of specific examples, which are provided to aid understanding of the invention and are not intended to be limiting. For a person skilled in the art to which the invention pertains, several simple deductions, modifications or substitutions may be made according to the idea of the invention.
