Abstract
Abstract In a distributed data processing system comprising a plurality of different computer systems, each system having a central processing unit (CPU), memory, a database stored in the memory, and a DBMS, a computerized method is provided for generating a plurality of objects in a standardized format. A unique object identifier is associated with each of the plurality of objects. Each unique object identifier is stored in memory in association with at least one object location type or instance, an object generation specification for each object location type or instance, and a generation specification type. For a requested object type at a specified location, identifying from the computer memory an object generation specification, and a specification type. The requested object is generated in a standardized format from the specified location using the identified process type and the identified object generation specification.

Claim 2
Dependent Claim
196 words
In a data processing system comprising a central processing unit (CPU), memory, and a plurality of database management systems (DBMSs) each associated with at least one database stored in the memory, wherein at least one DBMS is different from at least one other DBMS, a computerized method for the generation of objects in a standardized format comprising the steps of: (a) associating a unique object identifier with each of the plurality of objects; (b) storing in a table in a computer memory each unique object identifier in association with at least one object location type or instance corresponding to a particular database instance, an object generation specification for each object location type or instance, and a generation specification type, wherein said object generation specification for each object location type or instance specifies how an object is to be generated from said particular database instance; (c) for a requested object and a specified database, identifying from the table in the computer memory, an object generation specification, and a generation specification type; and (d) generating in a standardized format the requested object from the specified database using the identified generation specification type and the identified object generation specification.
Claim 3
Dependent Claim
27 words
The method of claim 1 wherein the object generation specification contains at least one qualifier identifier and requester supplied qualifier values are substituted for each qualifier identifier.
Claim 4
Dependent Claim
30 words
The method of claim 1 wherein the requested object is the object generation specification having a requester supplied qualifier value substituted for each qualifier identifier in the object generation specification.
Claim 5
Dependent Claim
40 words
The method of claim 1 wherein the object is a result of the object generation specification, having a requester supplied qualifier value substituted for each qualifier identifier in the object generation specification, executed as an SQL statement by a DBMS.
Claim 6
Dependent Claim
36 words
The method of claim 1 wherein the object is a result of the object generation specification executed as a program by a CPU with a requester supplied qualifier value substituted for each qualifier identifier program parameter.
Claim 7
Dependent Claim
26 words
The method of claim 1 wherein the standardized format comprises a pointer to the requested object with an indicator of the size of the requested object.
Claim 8
Dependent Claim
41 words
The method of claim 1 wherein each unique object identifier is stored in a set of at least one table in association with at least one object location, an object generation specification for each object location, and a generation specification type.
Claim 9
Dependent Claim
26 words
The method of claim 7 further comprising the step of adding a new object identifier and associated information to the set of at least one table.
Claim 10
Dependent Claim
171 words
In a distributed data processing system having a plurality of different computer systems, each system having a central processing unit (CPU), memory, a database stored in the memory, and a DBMS, a system for the generation of objects in a standardized format from each of the computer systems, comprising: means for associating a unique object identifier with each of the plurality of objects; means for storing in a table in a computer memory each unique object identifier in association with at least one object location type or instance, an object generation specification for each object location type or instance, and a specification type wherein said object generation specification for an object location type or instance specifies how object is to be generated from a particular computer system; means for identifying from the table in the computer memory, an object generation specification, and a generation specification type; and means for generating in a standardized format information about the requested object using the identified generation specification type and the identified object generation specification.
