Abstract
Abstract A technique for retrieving data residing on a data server platform using object-oriented programming techniques in a Desktop Management Interface ("DMI") environment is disclosed. In one embodiment, a data inquiry Router object brings together the many functions and data sources required to service client requests into a cohesive structure. Based on the concept that all data requests can be visualized as the instantiation of a class derived from a hyper-generic base class, a symbiotic structure is be generated that encapsulates the basic client-server interface functionality along with the otherwise unrelated information gathering techniques required to satisfy the request. The base class and all classes derived from it are accessed through an open-addressed hash table based request Router object that bores down to the appropriate piece of data acquisition code and performs query validation and return the requested data structure in the form desired.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
146 words
A computer-implemented method for retrieving data relating to one of a plurality of computer components, the method comprising: responsive to a request for data including a group and an attribute, determining whether said request relates to a component of which there are multiple instances; if said request relates to a component of which there are multiple instances, performing a linear search of alt attributes identified in a key list to obtain an index of said attribute of said request; indexing a hash table comprising a map of pointers to instrument objects using said group and said attribute of said request and said index to obtain a pointer to one of said instrument objects; sending a message to said one of said instrument objects for causing said one of said instrument objects to implement a particular method and obtain said requested data; and returning said requested data.
Claim 2
Dependent Claim
146 words
A computer-implemented method for retrieving data relating to one of a plurality of computer components, the method comprising: responsive to a request for data including a group and an attribute, determining whether said request relates to a component of which there are multiple instances; if said request relates to a component of which there are multiple instances, performing a linear search of alt attributes identified in a key list to obtain an index of said attribute of said request; indexing a hash table comprising a map of pointers to instrument objects using said group and said attribute of said request and said index to obtain a pointer to one of said instrument objects; sending a message to said one of said instrument objects for causing said one of said instrument objects to implement a particular method and obtain said requested data; and returning said requested data.
Claim 3
Dependent Claim
17 words
The method of claim 1 wherein said performing a linear search is performed by a Router object.
Claim 4
Dependent Claim
17 words
The method of claim 1 wherein each of said instrument objects corresponds to one of said components.
Claim 5
Dependent Claim
17 words
The method of claim 1 wherein said method is implemented in a desktop management interface ("DMI") environment.
Claim 6
Dependent Claim
22 words
The method of claim 4 wherein said DMI comprises a management interface ("MI"), a service layer ("SL"), and a component interface ("CI").
Claim 7
Dependent Claim

Claim 8
Dependent Claim
41 words
The method of claim 5 wherein said performing a linear search, indexing a hash table, sending a message, and returning said requested data are performed by a component instrumentation, said component instrumentation providing an interface between said CI and said components.
Claim 9
Independent Claim
155 words
A system for retrieving data relating to one of a plurality of computer components, the system comprising: means responsive to a request for data including a group and an attribute for determining whether said request relates to a component of which there are multiple instances; means for performing a linear search of all attributes identified in a key list to obtain an index of said attribute of said request if said request relates to a component of which there are multiple instances; means for indexing a hash table comprising a map of pointers to instrument objects using said group and said attribute of said request and said index to obtain a pointer to one of said instrument objects; means for sending a message to said one of said instrument objects for causing said one of said instrument objects to implement a particular method and obtain said requested data; and means for returning said requested data.
Claim 10
Independent Claim
155 words
A system for retrieving data relating to one of a plurality of computer components, the system comprising: means responsive to a request for data including a group and an attribute for determining whether said request relates to a component of which there are multiple instances; means for performing a linear search of all attributes identified in a key list to obtain an index of said attribute of said request if said request relates to a component of which there are multiple instances; means for indexing a hash table comprising a map of pointers to instrument objects using said group and said attribute of said request and said index to obtain a pointer to one of said instrument objects; means for sending a message to said one of said instrument objects for causing said one of said instrument objects to implement a particular method and obtain said requested data; and means for returning said requested data.
