Abstract
Abstract The present invention defines a consistent method and system for enabling components in an information system to invoke operations that may be distributed across multiple computing platforms, through the provision and use of executable operations whose behaviors are determined from information stored and extracted from a Catalog (164) using an Operation Definition Manager (82). The stored information is used by a Surrogate Object Definition Module (96) to define a Surrogate Object Type structure which enables execution of any of the operations described within it. A Surrogate Object Manager (94), along with an Operation Connection Manager (104, 118, 130 or 132), is provided which assists the user in developing applications by providing access to the definition of the input and output arguments of the operations included in the Surrogate Object Type structure (244). The present invention further includes an Operation Connection Manager (104, 118, 130 or 132) which, together with the Surrogate Object Manager (94), provides a consistent means for an Operation Requestor (92) to invoke an operation and exchange input and output arguments, independent of the intervening network communication protocol or the hardware platform type, operating system and database management system upon which the operation has been implemented.

Claim 4
Dependent Claim
21 words
The system of claim 1 further including an Application Development Tool operable to assist the user in constructing the Operation Requestor.
Claim 5
Dependent Claim
34 words
The system of claim 1 wherein the associated operation definition includes information defining input and output arguments of the executable operation and validation requirements of the input and output arguments of the executable operation.
Claim 6
Dependent Claim
95 words
The system of claim 1 wherein the Catalog includes: an Operation Enrollment Module for accepting and storing the information related to the executable operation in a Catalog database and for equating the input and output arguments of the executable operation with arguments of another executable operation using common predicates; a Catalog Manager for providing a set of access and data storage functions, the set of access and data storage functions enabling the user to add, update and delete records in the Catalog database; and a Catalog Editor for maintaining the information in the Catalog database.
Claim 7
Dependent Claim
31 words
The system of claim 5 wherein the Surrogate Object Definition Module is operable to present the information related to the executable operation to the user in terms of the common predicates.
Claim 8
Dependent Claim
