Problems solved by technology

When these data interactions cross-organizational and administrative boundaries problems arise.
These problems are based on the difficulty of managing a common definition and ensuring data compliance with the agreed upon data schema across the organizational and administrative boundaries.
Although practical, this kind of generic approach has two disadvantages when compared to the disclosed invention:1. Increased complexity of the engine implementation, and2. Longer execution times as a result of the indirection required to interpret the map specification at runtime.

Embodiment Construction

[0025]This application discloses a software tool that automatically generates the program code for a schema mapping application. The generated code includes a complete stand-alone application that can read in data files conforming to a specific source data schema and produce as output corresponding data files in which the input data has been transformed to conform to specific target data schemas. The user of this generation tool defines both the source and target schemas, and specifies the transformation from source to target to be performed. This transformation is known as the mapping specification. Based on this input, the tool invokes a series of code generators that produce source code that implements the desired schema mapping. It should be known by one skilled in the art that the disclosed invention might be utilized to produce source code in any programming language desired by the user. At generation time the user can select from a number of options that control various aspec...

Abstract

A method for automatic generation of schema mapping application code. The method includes loading a code generation tool with source and target schemas. The method further includes defining the mapping specification between the source and the target. The method proceeds by triggering the code generation tool. Afterwards, the method proceeds by compiling the generated code. Furthermore, the method includes executing the generated code to transform input data files.

Other names used herein may be registered trademarks, trademarks or product names of International Business Machines Corporation or other companies.BACKGROUND OF THE INVENTION[0002]1. Field of Invention[0003]This invention relates in general to information systems, and more particularly to data exchange and data storage among information systems.[0004]2. Description of Background[0005]Modern information systems rely heavily on both data exchange and data storage. Data exchange enables interaction between different components in an information system. Additionally, data exchange makes it possible for an information system to interact with other information systems. Data exchange between information systems is used to achieve interoperability and integration of disparate information systems, which may exist in disjoint administrative and organizational domains and is a k...
