Problems solved by technology

However, the current educational systems are complex, diverse, and heterogeneous, among which heterogeneity is reflected in the different sources of resource libraries, which brings great limitations to the sharing and application of educational resources. It is reflected in: firstly, each resource library system is scattered in different network nodes, and the hardware platform, operating system, network service platform and database platform that each node depends on may be different from each other; secondly, each The education resource system lacks the support of a unified resource standard, the semantic definition is not strict, and there are large differences in the organization and storage of resources, and it is impossible to carry out effective information exchange and resource sharing

Embodiment 1

[0054] see figure 1 A heterogeneous resource isomorphism method provided in Embodiment 1 of the present invention includes the following steps:

[0055]S11. Obtain the data in the heterogeneous source database, perform integration processing on the data according to the preset integration rules, and generate a centralized database of heterogeneous resources;

[0056] Specifically, a heterogeneous source database is a resource library with different sources. For example, based on the digital textbook database, multi-source and polymorphic resource databases such as interactive teaching courseware database, encyclopedia knowledge resource database, and third-party digital resource database can be collectively referred to as heterogeneous source databases. Isomorphizing heterogeneous resources is to integrate data resources from different sources into a resource library that can be accessed in one stop. In the embodiment of the present invention, the integrated educational reso...

Embodiment 2

[0063] Referring to embodiment one of the present invention and figure 1 The specific process of steps S11 to S13 described in , each step will be described in detail in the embodiments of the present invention.

[0064] see figure 2 , the step S11 acquires the data in the heterogeneous source database, integrates the data according to preset integration rules, and generates a heterogeneous resource centralized database, specifically including:

[0065] S111, the formulated standardized metadata structure;

[0066] Specifically, the metadata is metadata of heterogeneous resources, and the metadata of heterogeneous resources includes the characteristics and attributes describing information resources or data itself, and specifies the organization of digital information. In the application of metadata, it is clear through resource analysis It defines the digital objects and related requirements corresponding to the metadata. That is to say, in the present invention, attribut...

Embodiment 3

[0100] Corresponding to the method for isomorphizing heterogeneous resources disclosed in Embodiment 1 and Embodiment 2 of the present invention, Embodiment 3 of the present invention also provides a device for isomorphizing heterogeneous resources, see Figure 5 , the device consists of:

[0101] A generating module 1, configured to acquire data in heterogeneous source databases, integrate the data according to preset integration rules, and generate a centralized database of heterogeneous resources;

[0102] A setting module 2, configured to set the connection relationship between the heterogeneous resource centralized database and the query application layer;

[0103] The query module 3 is configured to, when the application layer receives a resource query request, query the heterogeneous resource centralized database through the connection relationship, and obtain data information corresponding to the query request.

[0104] Correspondingly, the generating module 1 include...

Abstract

The invention discloses a heterogeneous resource isomorphism method and device. Data in a heterogeneous resource database is obtained, integrated processing is conducted on the data according to a preset integration rule to generate a heterogeneous resource integrated database; the connecting relation between the heterogeneous resource database and a query application layer is set; when the application layer receives a resource query request, the heterogeneous resource database is queried via the connecting relation to obtain data information corresponding to the query request. By combining and integrating heterogeneous data different in source according to resource forms and accessing the data via an application layer access request, heterogeneous resources are integrated to form a resource library which is isomorphic in application layer and can be transparently accessed in a one-stop mode, and thus the purpose of integrating and sharing data resources is achieved.

Description

technical field [0001] The present invention relates to the technical field of information sharing, in particular to a method and device for homogenizing heterogeneous resources. Background technique [0002] In recent years, with the gradual popularization and deepening of resource construction work, the number of teaching resources has grown rapidly. However, the current educational systems are complex, diverse, and heterogeneous, among which heterogeneity is reflected in the different sources of resource libraries, which brings great limitations to the sharing and application of educational resources. It is reflected in: firstly, each resource library system is scattered in different network nodes, and the hardware platform, operating system, network service platform and database platform that each node depends on may be different from each other; secondly, each The education resource system lacks the support of a unified resource standard, the semantic definition is not...
