Abstract

An apparatus for and method of utilizing an Internet terminal coupled to the world wide web to access a legacy data base management system having a dialog-based request format using a standardized object-based command language, such as JavaScript, rather than the proprietary command language native to the legacy data base management system. This approach leverages the power of the legacy data base management without the need for the user to become familiar with the proprietary command language of the legacy data base management system. The approach is particularly efficient in that the user can provide parameters to the legacy data base management system as a parameter object.

Claims

1. An apparatus comprising:

a. a user terminal which generates a user request in a standardized object-based command language;

b. a legacy data base management system responsively coupled to said user terminal which honors said user request by execution of a non-standardized command language;

c. a conversion facility for conversion of said standardized object-based command language to said non-standardized command language; and

d. a parameter object responsively coupled to said legacy data base management system which provides definitions for honoring of said user request by said legacy data base management system.

2. The apparatus of claim 1 wherein said user terminal is coupled to said legacy data base management system via a publically accessible digital data communication network.

3. The apparatus of claim 2 wherein said parameter object is defined by said standardized object-based command language.

4. The apparatus of claim 3 wherein said publically accessible digital data communication network further comprises the Internet.

5. The apparatus of claim 4 wherein said standardized object-based command language further comprises JavaScript.

6. A method of utilizing a user terminal to access a legacy data base management system employing a non-standardized command language comprising:

a. transmitting a service request in a standardized object-based command language from said user terminal requesting access to said legacy data base management system;

b. receiving said service request by said legacy data base management system;

c. converting said service request in said standardized object-based command language into said non-standardized command language;

d. accessing a parameter object by said legacy data base management system; and

e. honoring said service request by executing said non-standardized command language by said legacy digital data base management system.

7. A method according to claim 6 wherein said parameter object is initially defined in said standardized object-based command language.

8. A method according to claim 7 wherein said transmitting step occurs over a publically accessible digital data communication network.

9. A method according to claim 8 wherein said publically accessible digital data communication network further comprises the Internet.

10. A method according to claim 9 wherein said standardized object-based command language further comprises JavaScript.

11. An apparatus comprising:

a. permitting means for permitting a user to transfer a service request defined by a standardized object-based command language;

b. offering means responsively coupled to said permitting means via said publically accessible digital data communication network for offering legacy data base management services involving access to at least one data base having a non-standard scripted command language;

c. converting means responsively coupled to said offering means for converting said service request from said standardized object-base command language to said non-standardized scripted command language; and

d. maintaining means responsively coupled to said offering means for maintaining a parameter object.

12. An apparatus according to claim 11 wherein said maintaining means further comprises means said standardized object-based command language.

13. An apparatus according to claim 12 further comprising means located within said permitting means for generating a second service request.

14. An apparatus according to claim 13 wherein said offering means further comprises MAPPER data base management system.

15. An apparatus according to claim 14 wherein said permitting means further comprises an industry standard personal computer.

16. In a data processing system having a user terminal which generates a service request in a standardized object-based command language responsively coupled to a legacy data base management system which honors said service request by executing a non-standardized command language, the improvement comprising:

a. a conversion facility responsively coupled to said legacy data base management system which converts said service request from said standardized object-based command language to said non-standardized command language; and

b. a parameter object responsively coupled to said legacy data base management system which assists said legacy data base management system in honoring said service request.

17. The improvement according to claim 16 wherein said parameter object is defined by said standardized object-based command language.

18. The improvement according to claim 17 wherein said user terminal is responsively coupled to said legacy data base management system via a publically accessible digital data communication network.

19. The improvement according to claim 18 wherein said publically accessible digital data communication network further comprises the Internet.

20. The improvement according to claim 19 wherein said standardized object-based command language further comprises JavaScript.

21. An apparatus for accessing a database comprising:

a. a user terminal which generates a user request in a JavaScript like standardized object-based command language;

b. a legacy data base management system responsively coupled via a publically accessible digital data communication network to said user terminal which honors said user request by execution of a non-standardized command language;

c. a conversion facility for conversion of said standardized object-based command language to said non-standardized command language; and

d. a parameter object defined by said standardized object-based command language responsively coupled to said legacy data base management system which provides definitions for honoring of said user request by said legacy data base management system.
