to getting the object from database; Converting object refers to the transformation from the obtained object
into the identified memory object. Operation mapping module includes acquisition and transformation.
Acquisition refers to the operation of topological interfaces, resource tree, information in the table, such as the
operational records of modifying/deleting/adding the managed object. Operation transformation refers that the
operating results are saved to the database.
