Abstract

A method for restructuring input data having a prespecified input data structure with a data management engine, such as a translation engine, which is dynamically configured by the input data to conform the input data to an output data structure. When the data management engine takes the form of a translation engine, capability exists to translate data to and from various electronic data interchange (EDI) formats. Because the data management engine is dynamically configured by the input data, the translation process is independent of the specific details of EDI protocol and capable of coordinating multiple data sources/destinations without requiring any recoding of the engine. Initially, data protocol utilized in the data interchange system is ascertained. Then, the protocol data related to the data protocol and protocol processing instruction data is initialized. Next, the initialized protocol data and the initialized protocol instruction processing data is linked to a core program which takes the form of a translator in the EDI system to form the translation engine. Finally, the input data is converted into an output data structure with the translation engine wherein the input data dynamically configures the translation engine.

Claims

1. In an electronic information processing system including a pre-existing core program, EDI protocol data and protocol processing instruction data, a method for conforming input data into an output data structure, the method comprising the steps of:

ascertaining, by the pre-existing core program in said system, an EDI protocol to be utilized in the system based on characteristics of the input data;

selecting the EDI protocol data by the pre-existing core program, the EDI protocol data describing a syntax of the EDI protocol, the EDI protocol data including at least one data model;

selecting the protocol processing instruction data by the pre-existing core program, the protocol processing instruction data including at least one layer of elements, the protocol processing instruction data describing trading partner specific editing and validation logic;

initializing, in said system, the selected EDI protocol data related to the EDI protocol and protocol processing instruction data;

linking, in the system, the initialized EDI protocol data and the initialized protocol processing instruction data to the pre-existing core program to form a data management engine; and

converting, with the data management engine, the input data into the output data structure, the data management engine being. dynamically configured based on the EDI protocol data, the protocol processing instruction data and the core program.

2. The method as claimed in claim 1 wherein the at least one layer of elements includes a first layer of data element descriptions and wherein the step of initializing includes the step of allocating memory for each data element description.

3. The method of claim 2 wherein the at least one layer of elements includes a second layer of segment descriptions and wherein the step of initializing includes the step of allocating memory for each segment description.

4. The method of claim 3 wherein the at least one layer of elements includes a third layer of transaction set descriptions and wherein the step of initializing includes the step of allocating memory for each transaction set description.

5. The method as claimed in claim 1 or 2 or 3 or 4 wherein the initialized protocol processing instruction data includes a layer of transaction behavior descriptions and wherein the step of initializing includes the step of allocating memory for each transaction behavior description.

6. The method as claimed in claim 4 wherein a first transaction set description includes a second transaction set description.

7. The method of claim 6 wherein a position of the second transaction set description represents semantic information.

8. The method of claim 6 wherein the absence of the second transaction set description represents semantic information.

9. The method as claimed in claim 1 wherein the step of initializing includes the step of allocating memory for a table of each of the layer elements.

10. The method as claimed in claim 1 wherein at least one of the layer elements has corresponding behaviors and wherein said step of initializing includes the step of allocating memory for a table for each of the layer elements and the corresponding behaviors.

11. The method as claimed in claim 9 or 10 wherein the step of initializing includes the step of providing a first set of control data to associate the layer elements including the tables of each of the layer elements.

12. The method as claimed in claim 11 wherein the step of converting includes the step of obtaining a second set of control data from a control data source of the system, the second set of control data being utilized to process the EDI protocol data with the input data.

13. In an electronic information processing system including a core program, EDI protocol data including at least one data and protocol processing instruction data describing trading partner specific editing and validation data, an apparatus for conforming input data into an output data structure, the apparatus comprising:

means for ascertaining, in said system, an EDI protocol to be utilized in the system;

means for selecting the EDI protocol data by the pre-existing core program;

means for selecting the protocol processing instruction data by the pre-existing core program;

means for initializing, in said system, the selected EDI protocol data related to the EDI protocol and protocol processing instruction data;

means for linking, in the system, the initialized EDI protocol data and the initialized protocol processing instruction data to the pre-existing core program to form a data management engine, the data management engine converting the input data into the output data structure, the data management engine being. dynamically configurable based on the EDI protocol data, the protocol processing instruction data and the core program.
