Abstract

A system and computer program product for developing software in which the software comprises a plurality of programs. A change to a program is received. A data structure checking procedure may then be invoked. The changed program is parsed for a reference to a data structure. Other instances of the data structure are located in other programs within the software. The referenced data structure is compared to the located other instances of the data structure. A predefined action (such as notifying a programmer or correcting the inconsistencies) is performed in response to any detected differences between the referenced data structure and the located other instances of the data structure. These steps are repeated for all data structures within the changed program.

First claim

The invention claimed is:

1. A computer program product embodied in a non-transitory computer readable storage medium, wherein the medium does not include a propagating signal, for developing software, the software comprising a plurality of programs, the computer program product comprising the programming instructions for:
receiving a change to a program out of a plurality of programs within the software;
invoking a data structure checking procedure for checking any data structures within the changed program;
parsing the changed program for a reference to a data structure;
locating other instances of the data structure referenced by other programs within the software by locating data structures with a same name and structure features as the referenced data structure;
comparing layout, length, field names, field lengths and field types of the referenced data structure to the located other instances of the data structure to validate that their structures have remained consistent;
performing a predefined action in response to any detected differences between the referenced data structure and the located other instances of the data structure, wherein the performing of the predefined action comprises outputting a report informing a programmer of an existence of the other instances of the data structure, its location and details of detected differences between the referenced data structure and the other instances of the data structure, wherein the performing of the predefined action further comprises performing an auto-correction of those other instances of the data structure with a detected difference from the referenced data structure that are located elsewhere within the software to match the referenced data structure;
repeating said parsing, locating, comparing and performing for all data structures within the changed program;
detecting one or more other data structures considered to be similar to the referenced data structure based on a specific percentage of field numbers and lengths being identical; and
providing the programmer an opportunity to determine if the one or more other detected data structures considered to be similar to the referenced data structure are actually supposed to be the same as the referenced data structure thereby enabling the programmer to change those detected data structures considered to be similar manually if need be.

2. The computer program product as recited in claim 1 further comprising the programming instructions for:
generating a notification detailing the detected similar one or more data structures.

3. A system, comprising:
a memory unit for storing a computer program for developing software, the software comprising a plurality of programs; and
a processor coupled to the memory unit, wherein the processor, responsive to the computer program, comprises:
circuitry for receiving a change to a program out of a plurality of programs within the software;
circuitry for invoking a data structure checking procedure for checking any data structures within the changed program;
circuitry for parsing the changed program for a reference to a data structure;
circuitry for locating other instances of the data structure referenced by other programs within the software by locating data structures with a same name and structure features as the referenced data structure;
circuitry for comparing layout, length, field names, field lengths and field types of the referenced data structure to the located other instances of the data structure to validate that their structures have remained consistent;
circuitry for performing a predefined action in response to any detected differences between the referenced data structure and the located other instances of the data structure, wherein the performing of the predefined action comprises outputting a report informing a programmer of an existence of the other instances of the data structure, its location and details of detected differences between the referenced data structure and the other instances of the data structure, wherein the performing of the predefined action further comprises performing an auto-correction of those other instances of the data structure with a detected difference from the referenced data structure that are located elsewhere within the software to match the referenced data structure;
circuitry for repeating said parsing, locating, comparing and performing for all data structures within the changed program;
circuitry for detecting one or more other data structures considered to be similar to the referenced data structure based on a specific percentage of field numbers and lengths being identical; and
circuitry for providing the programmer an opportunity to determine if the one or more other detected data structures considered to be similar to the referenced data structure are actually supposed to be the same as the referenced data structure thereby enabling the programmer to change those detected data structures considered to be similar manually if need be.

4. The system as recited in claim 3 , wherein the processor further comprises:
circuitry for generating a notification detailing the detected similar one or more data structures.

5. The computer program product as recited in claim 1 , wherein the comparison of the referenced data structure to the located other instances of the data structure is performed by a plug-in of an integrated development environment.

6. The computer program product as recited in claim 1 , wherein the changed program that references the data structure and a second program within the software that references an instance of the data structure are written by different programmers.

7. The system as recited in claim 3 , wherein the comparison of the referenced data structure to the located other instances of the data structure is performed by a plug-in of an integrated development environment.

8. The system as recited in claim 3 , wherein the changed program that references the data structure and a second program within the software that references an instance of the data structure are written by different programmers.
