Abstract

Claims (59)

1. A computer system comprising:

at least one processor; and

a memory storing a common data model of a configuration management database (CMDB), the common data model including at least a first class and a second class, the memory also storing instructions that, when executed by the at least one processor, cause the system to perform operations comprising:

marking the first class of the common data model as deprecated,

selecting the second class of the common data model as a replacement for the first class,

moving data associated with a first instance of the first class in the CMBD to a second instance of the second class in the CMDB, according to a mapping between the first class and second class, and

accessing, via the mapping, the second instance of the second class in response to a request for the first instance of the first class.

2. The system of claim 1 , wherein accessing the second instance includes:

directing the request for the first instance of the first class to a deprecation module, the deprecation module being configured to:

make, based on the mapping, a CMDB application program interface call to access the second instance,

receive data for the second instance,

map the data for the second instance to a format of the first instance using the mapping, and

provide the data in the format for the first instance in response to the request.

3. The system of claim 1 , wherein the second class is a superclass of the first class.

4. The system of claim 1 , wherein the second class is a sibling class of the first class.

5. The system of claim 1 , wherein the second class is a sibling class of a superclass of the first class.

6. The system of claim 1 , wherein moving data associated with the first instance of the first class to the second instance of the second class includes:

modifying data structures of the second class according to the mapping;

moving the data; and

modifying data structures of the first class according to the mapping.

7. The system of claim 6 , wherein the mapping maps an attribute of the first class to an existing attribute of the second class.

8. The system of claim 6 , wherein the mapping maps an attribute of the first class to a new attribute of the second class.

9. The system of claim 6 , wherein the mapping maps a default value to an attribute of the second class.

10. The system of claim 6 , the memory further storing instructions that, when executed by the at least one processor, cause the system to perform further operations comprising:

storing the mapping as an instance of a third class in the common data model.

11. The system of claim 6 , wherein the mapping includes an indication of whether an instance of the second class can be considered as an instance of the first class.

12. The system of claim 1 , the memory further storing instructions that, when executed by the at least one processor, cause the system to perform further operations comprising:

changing a definition of a form used to access the first class so that the second class is accessed.

13. A method comprising:

receiving a request to deprecate a first class in a common data model of a configuration management database (CMDB);

selecting a second class of the common data model as a replacement for the first class;

moving data associated with a first instance of the first class in the CMBD to a second instance of the second class in the CMDB according to a mapping between the first class and second class;

marking the first class as deprecated in the common data model; and

accessing, via the mapping, the second instance of the second class in response to a request for the first instance of the first class.

14. The method of claim 13 , wherein accessing the second instance includes:

receiving a request for the data associated with the first instance of the first class; and

directing, responsive to determining the first class is deprecated, the request to a deprecation module configured to:

make, based on the mapping, a CMDB application program interface call to access the second instance of the second class,

receive data from the second instance, and

map the data for the second instance to a format of the first instance using the mapping, and

provide the data in the format for the first instance in response to the request.

15. The method of claim 13 , further comprising:

changing a definition of a form used to access the first class so that the second class is accessed.

16. The method of claim 15 , wherein the form is a first form having a name and the method further comprises:

creating a vendor form with fields from the first form;

deleting the first form; and

renaming the vendor form to the name of the first form.

17. The method of claim 13 , wherein moving data associated with the first instance of the first class to the second instance of the second class includes:

receiving the mapping between the first class and second class from a user.

18. The method of claim 13 , wherein moving data associated with the first instance of the first class to the second instance of the second class includes:

modifying data structures of the second class according to the mapping;

moving the data; and

modifying data structures of the first class according to the mapping.

19. The method of claim 13 , further comprising:

identifying at least one relationship in the CMDB specifying the first instance of the first class; and

changing a class identifier for the first class in the relationship to a class identifier of the second class.

20. The method of claim 13 , wherein selecting the second class includes:

creating a new class in the common data model; and

selecting the new class as the replacement for the first class.
