Abstract

In one embodiment the present invention includes a computer-implemented for determining whether or not a data object is frozen. The method comprises accessing, by a user on a computer, a first data object of a plurality of data objects in one or more computer software applications. The plurality of data objects are assigned to a plurality of entities, where each entity specifies a category, and each of the plurality of data objects belong to a specific entity. The method determines if the first data object is frozen based on a relationship between the first entity and a second entity.

Claims

1. A computer-implemented method comprising:

accessing, by a user on a computing device, a first data object of a plurality of data objects in one or more computer software applications, wherein the plurality of data objects are assigned to a plurality of entities, each entity specifying a category, wherein each of the plurality of data objects belong to a specific entity, wherein the first data object is assigned to a first entity, wherein a second data object is assigned to a second entity, and wherein the second data object is frozen;

allowing the user to perform write actions on the first data object when a relationship between the first entity and the second entity indicates that the first data object is not frozen; and

denying the user from performing write actions on the first data object when the relationship between the first entity and the second entity indicates that the first data object is frozen, including determining if the first object is frozen by;

detecting the first entity to which the first data object is assigned;

accessing a registry of entities, wherein the registry specifies one or more of the plurality of entities, and wherein a particular is specified in the registry if a data object assigned to the particular entity is frozen or if the particular entity is related to an entity having an assigned frozen data object; and

detecting whether the first entity is in the registry.

2. The method of claim 1 wherein the first data object is determined to be frozen or not frozen in response to the first data object being accessed.

3. The method of claim 1, each data object of the plurality of data objects comprising an object identification, the object identification specifying the particular entity to which a particular data object is assigned and a database identifier.

4. The method of claim 1, said determining further comprising:

accessing path information, the path information specifying a relationship path from the first entity, through zero or more intermediate entities, to the second entity.

5. The method of claim 4 wherein the relationship path is unique.

6. The method of claim 4 wherein the relationship path is time dependent and wherein the relationship path is determined using a time stamp.

7. The method of claim 4, said determining further comprising:

determining whether or not the second entity is related to the first entity using the path information; and

if the second entity is related to the first entity, determining whether or not the second data object assigned to the second entity is frozen.

8. The method of claim 7 wherein the first data object has a plurality of attribute values each having an associated time, said determining further comprising comparing at least one associated time to a frozen time, wherein if the associated time meets a frozen date, then the first data object is frozen.

9. The method of claim 8 wherein the associated time is a date, wherein a first attribute of the first data object has an associated date, wherein the frozen time is a frozen date, and wherein the first data object is frozen if the date is before the frozen date.

10. The method of claim 8 wherein the associated time is a date, wherein a first attribute of the first data object has an associated date, wherein the frozen time is a frozen date range, and wherein the first data object is frozen if the date is within the frozen date range.

11. A non-transitory computer-readable medium containing instructions for controlling a computer system to perform a method, the method comprising:

accessing, by a user on a computer, a first data object of a plurality of data objects in one or more computer software applications, wherein the plurality of data objects are assigned to a plurality of entities, each entity specifying a category, wherein each of the plurality of data objects belong to a specific entity, wherein the first data object is assigned to a first entity, wherein a second data object is assigned to a second entity, and wherein the second data object is frozen;

allowing the user to perform write actions on the first data object when a relationship between the first entity and the second entity indicates that the first data object is not frozen; and

denying the user from performing write actions on the first data object when the relationship between the first entity and the second entity indicates that the first data object is frozen, including determining if the first object is frozen by;

detecting the first entity to which the first data object is assigned;

accessing a registry of entities, wherein the registry specifies one or more of the plurality of entities, and wherein a particular entity is specified in the registry if a data object assigned to the particular entity is frozen or if the particular entity is related to an entity having an assigned frozen data object; and

detecting whether the first entity is in the registry.

12. The non-transitory computer-readable medium of claim 11 wherein the first data object is determined to be frozen or not frozen in response to the first data object being accessed.

13. The non-transitory computer-readable medium of claim 11, each data object of the plurality of data objects comprising an object identification, the object identification specifying the particular entity to which a particular data object is assigned and a database identifier.

14. The non-transitory computer-readable medium of claim 11, said determining further comprising:

accessing path information, the path information specifying a relationship path from the first entity, through zero or more intermediate entities, to the second entity.

15. The non-transitory computer-readable medium of claim 14 wherein the relationship path is unique.

16. The non-transitory computer-readable medium of claim 14 wherein the relationship path is time dependent and wherein the relationship path is determined using a time stamp.

17. The non-transitory computer-readable medium of claim 14, said determining further comprising:

determining whether or not the second entity is related to the first entity using the path information; and

if the second entity is related to the first entity, determining whether or not the second data object assigned to the second entity is frozen.

18. The non-transitory computer-readable medium of claim 17 wherein the first data object has a plurality of attribute values each having an associated time, said determining further comprising comparing at least one associated time to a frozen time, wherein if the associated time meets a frozen date, then the first data object is frozen.
