Techniques for generically accessing data
View Patent ↗Techniques for generic data access are provided. A middle-tier server agent uses data providers that can communicate with backend resources. A request received in a first format is used to identify a specific data provider by the middle-tier server agent; the data provider uses the first format to communicate with a specific backend resource in a second format. Results from the specific backend resource are returned from the data provider in the first format and passed to a client that initially made the request.
1. A method implemented and residing within a computer-readable storage medium that is executed by one or more processors of a network to perform the method, comprising:
receiving, on a server, a data request for a backend resource from a client, the data request in a first format and the backend resource recognizes and processes a second format;
locating, on another server different from the server, a data provider to communicate with the backend resource, the data provider translates the first format to the second format using a backend Application Programming Interface (API) calls understood by the backend resource;
using the data provider to process the data request in the second format;
acquiring results from the data provider in the first format;
providing the results to the client in the first format;
parsing metadata from the results as auditing information and evaluating portions of the metadata based on a policy to take actions; and
assisting in enforcing security, auditing, reporting, and logging based on the auditing information.
2. The method of claim 1 further comprising, caching the results in the first format on the server.
3. The method of claim 1 further comprising, synchronizing the results from a cache of the server with a cache on the client and with other caches on other clients, which are interfaced to the server.
4. The method of claim 1 further comprising, registering a new data provider on the server for a handling a third format for a new backend resource of the server.
5. The method of claim 1 further comprising, maintaining the metadata with the data request and the results in the first format.
6. The method of claim 1 , wherein receiving further includes recognizing the first format as data fields, data values for the data fields, and a generic Application Programming interface (API) call.
7. The method of claim 6 , wherein recognizing further includes identifying, via the data provider, that the backend resource uses a different API call that the data provider maps the API call to.
8. The method of claim 1 , wherein locating further includes obtaining a backend resource identifier from the data request and using the backend resource identifier to consult a registry service that provides back a data provider identifier for the data provider.
9. The method of claim 1 , wherein acquiring further includes providing data synchronization and management of the results in the first format from the server on behalf of the client and other clients.
10. The method of claim 1 , wherein acquiring further includes enforcing access security against the data results in the first format before supplying to the client in response to policy evaluation.
11. A method implemented and residing within a computer-readable storage medium that is executed by one or more processors of a network to perform the method, comprising:
issuing a request to a server for access to data of a backend resource, the request in a first format and the backend resource recognizes and uses a second format that is different from the first format of the request, the server acts as a generic intermediary for the backend resource and other resources and locates a specific data provider that translates the first format to the second format and the specific data provider on an entirely different server from the server, that data provider using specific Application Programming Interface calls recognized by the backend resource;
receiving results in response to the request from the server, the results in the first format;
parsing results for metadata representing auditing information that is evaluated and actions taken based on a policy; and
assisting in enforcing security, auditing, logging, and reporting based on the auditing information.
12. The method of claim 11 further comprising:
issuing a second request to the server for access to other data of a different backend resource, the second request in the first format and the different backend resource recognizes and uses a different third format; and
receiving second results in response to the second request from the server, the second results in the first format.
13. The method of claim 12 further comprising, joining or merging the results and the second results together to form third results.
14. The method of claim 11 further comprising, caching the results in the first format in a cache on a client that processes the method, the client lacks the capability to cache the results in the second format.
15. The method of claim 11 , wherein issuing further includes formulating an operation with the request defined from a generic Application Programming Interface (API), the backend resource using a different operation from a different API.
16. The method of claim 11 , wherein receiving further includes parsing the metadata from the results in the first format and evaluating the metadata in response to policy.
