Abstract

Replicating data in a distributed database having a plurality of nodes is disclosed. Replicating includes receiving a semantic command at a local version of the database at a node, interpreting the semantic command, and applying the semantic command to the local version of the database.

Claims

1. A method of replicating data in a distributed database having a plurality of nodes, including:

receiving a semantic command at a local version of the database at a node;

interpreting the semantic command; and

applying the semantic command to the local version of the database.

2. A method as recited in claim 1, further including determining an operation associated with the semantic command.

3. A method as recited in claim 1, wherein the node is a master.

4. A method as recited in claim 1, further including propagating the semantic command.

5. A method as recited in claim 1, wherein the semantic command originated at a master.

6. A method as recited in claim 1, wherein the semantic command originated at another node.

7. A method as recited in claim 1, wherein the command is described in XML.

8. A method as recited in claim 1, wherein the node is a passive node in a high availability pair.

9. A method as recited in claim 1, further including translating the semantic command to into a set of one or more semantic commands wherein the semantic command has a meaning in a first context that is characteristic of a first node and wherein the set of commands has a meaning in a second context that is characteristic of the second node.

10. A method of replicating a local database on a remote node, including:

translating a semantic command into a set of one or more semantic commands wherein the semantic command has a meaning in a first context that is characteristic of a first node and wherein the command defines a first transaction that is executed at the first node; and

executing the set of semantic commands at a second node wherein the set of semantic commands has a meaning in a second context that is characteristic of the second node and wherein the set of commands defines a transaction at the second node that replicates the effect of the first transaction on the first node.

11. A computer program product for replicating data in a distributed database having a plurality of nodes, the computer program product being embodied in a computer readable medium and comprising computer instructions for:

receiving a semantic command at a local version of the database at a node;

interpreting the semantic command; and

applying the semantic command to the local version of the database.

12. A computer program product as recited in claim 11, the computer program product further comprising computer instructions for determining an operation associated with the semantic command.

13. A computer program product as recited in claim 11, wherein the node is a master.

14. A computer program product as recited in claim 11, the computer program product further comprising computer instructions for propagating the semantic command.

15. A computer program product as recited in claim 11, wherein the semantic command originated at a master.

16. A computer program product as recited in claim 11, wherein the semantic command originated at another node.

17. A computer program product as recited in claim 11, wherein the command is described in XML.

18. A computer program product as recited in claim 11, wherein the node is a passive node in a high availability pair.

19. A computer program product as recited in claim 11, the computer program product further comprising computer instructions for translating the semantic command to into a set of one or more semantic commands wherein the semantic command has a meaning in a first context that is characteristic of a first node and wherein the set of commands has a meaning in a second context that is characteristic of the second node.

20. A computer program product for replicating a local database on a remote node, the computer program product being embodied in a computer readable medium and comprising computer instructions for:

translating a semantic command into a set of one or more semantic commands wherein the semantic command has a meaning in a first context that is characteristic of a first node and wherein the command defines a first transaction that is executed at the first node; and

executing the set of semantic commands at a second node wherein the set of semantic commands has a meaning in a second context that is characteristic of the second node and wherein the set of commands defines a transaction at the second node that replicates the effect of the first transaction on the first node.

21. A system for replicating data in a distributed database having a plurality of nodes, including:

a processor configured to;

receive a semantic command at a local version of the database at a node;

interpret the semantic command; and

apply the semantic command to the local version of the database; and

a memory coupled with the processor, wherein the memory provides the processor with instructions.

22. A system as recited in claim 21, wherein the processor is further configured to determine an operation associated with the semantic command.

23. A system as recited in claim 21, wherein the node is a master.

24. A system as recited in claim 21, wherein the processor is further configured to propagate the semantic command.

25. A system as recited in claim 21, wherein the semantic command originated at a master.

26. A system as recited in claim 21, wherein the semantic command originated at another node.

27. A system as recited in claim 21, wherein the command is described in XML.

28. A system as recited in claim 21, wherein the node is a passive node in a high availability pair.

29. A system as recited in claim 21, wherein the processor is further configured to translate the semantic command to into a set of one or more semantic commands wherein the semantic command has a meaning in a first context that is characteristic of a first node and wherein the set of commands has a meaning in a second context that is characteristic of the second node.

30. A system for replicating a local database on a remote node, including:

a processor configured to;

translate a semantic command into a set of one or more semantic commands wherein the semantic command has a meaning in a first context that is characteristic of a first node and wherein the command defines a first transaction that is executed at the first node; and

execute the set of semantic commands at a second node wherein the set of semantic commands has a meaning in a second context that is characteristic of the second node and wherein the set of commands defines a transaction at the second node that replicates the effect of the first transaction on the first node; and

a memory coupled with the processor, wherein the memory provides the processor with instructions.
