Technique for accessing a database of serializable objects using field values corresponding to fields of an object marked with the same index value

1. A computer implemented method to access a database of records, comprising:

executing by the database a command including a field value and an index value, wherein multiple fields of an object are marked with a same index value, the database storing flat contiguous memory structures as records, each of the flat contiguous memory structures converted from field values of a respective object by a database converter;

passing multiple field values to the database, the multiple field values corresponding to the multiple fields of the object marked with the same index value;

searching the database to determine whether any of the records stored in the database include the multiple field values in matching fields indicated by the index value;

where the searching determines that the database includes at least one record with the field values in matching fields indicated by the same index value, returning the at least one record stored in the database as one of the flat contiguous memory structures;

in response to the returning the at least one record, calling a method of the object to convert the at least one record from the one of the flat contiguous memory structures into a complex of linked memory structures; and

providing the complex of linked memory structures for populating a plurality of fields of the object.

2. The computer implemented method of claim 1 , further comprising:

creating the object as an empty object with unset empty fields; and

setting a selected field from among the unset empty fields with the field value, wherein the field value functions as a key for searching the database.

3. The computer implemented method of claim 2 , wherein the records stored in the database are stored as flat contiguous memory structures, the method further comprising:

converting the field value to a flat contiguous memory structure prior to searching the database with the field value.

4. The computer implemented method of claim 2 , further comprising passing to the command the index number, the object with the selected field set, and a destination object to which the plurality of field values should be returned, wherein the index number defaults to a primary index associated with a unique field value in the database, if the index number is not provided.

5. The computer implemented method of claim 1 , wherein the object comprises a serializable object.

6. The computer implemented method of claim 1 , further comprising:

setting a selected field from among a plurality of fields in the object; and

writing only the field value of the selected field to the database.

7. The computer implemented method of claim 1 , wherein the database comprises a provisioning database and wherein the records comprise provisioning records for provisioning a network service node to couple between at least two networks.

8. The computer implemented method of claim 1 , wherein the database comprises a runtime database and wherein the records comprise runtime data of a network service node to couple between at least two networks.

9. The computer implemented method of claim 1 , wherein the database is accessible through a management layer application programming interface (“MLAPI”), the method further comprising:

providing an extensible markup language (“XML”) file at an interface layer;

invoking a create command published by the MLAPI to the interface layer;

converting the XML file to the object;

converting the object to a flat contiguous memory structure; and

storing the flat contiguous memory structure to the database.

10. A machine-accessible storage medium that provides instructions that, if executed by a machine, will cause the machine to perform operations comprising:

executing by the database a command including a field value and an index value, wherein multiple fields of an object are marked with a same index value, the database storing flat contiguous memory structures as records, each of the flat contiguous memory structures converted from field values of a respective object by a database converter;

passing multiple field values to the database, the multiple field values corresponding to the multiple fields of the object marked with the same index value;

searching the database to determine whether any of the records stored in the database include the multiple field values in matching fields indicated by the index value;

where the searching determines that the database includes at least one record with the field values in matching fields indicated by the same index value, returning the at least one record stored in the database as one of the flat contiguous memory structures;

in response to the returning the at least one record, calling a method of the object to convert the at least one record from the one of the flat contiguous memory structures into a complex of linked memory structures; and

providing the complex of linked memory structures for populating a plurality of fields of the object.

11. The machine-accessible storage medium of claim 10 , further providing instructions that, if executed by the machine, will cause the machine to perform further operations, comprising:

creating the object as an empty object with unset empty fields; and

setting a selected field from among the unset empty fields with the field value, wherein the field value functions as a key for searching the database.

12. The machine-accessible storage medium of claim 11 , wherein the records stored in the database are stored as flat contiguous memory structures, and further providing instructions that, if executed by the machine, will cause the machine to perform further operations, comprising:

converting the field value to a flat contiguous memory structure prior to searching the database with the field value.

13. The machine-accessible storage medium of claim 11 , further providing instructions that, if executed by the machine, will cause the machine to perform further operations, comprising:

passing to the command the index number, the object with the selected field set, and a destination object to which the plurality of field values should be returned, wherein the index number defaults to a primary index associated with a unique field value in the database, if the index number is not provided.

14. The machine-accessible storage medium of claim 10 , wherein the object comprises a serializable object.

15. The machine-accessible storage medium of claim 10 , further providing instructions that, if executed by the machine, will cause the machine to perform further operations, comprising:

setting a selected field from among a plurality of fields in the object; and

writing only the field value of the selected field to the database.

16. The machine-accessible storage medium of claim 10 , wherein the database is accessible through a management layer application programming interface (“MLAPI”), and further providing instructions that, if executed by the machine, will cause the machine to perform further operations, comprising:

providing an extensible markup language (“XML”) file at an interface layer;

invoking a create command published by the MLAPI to the interface layer;

converting the XML file to the object;

converting the object to a flat contiguous memory structure; and

storing the flat contiguous memory structure to the database.
