Data structures, methods and devices for implementing persistence data storage such that persistent objects may be efficiently created and accessed in a distributed client/server computing system are disclosed. In one aspect of the invention, a method for managing persistence data for installed persistent objects involves marshaling a persistent object attribute value into a marshal buffer to provide an encoded persistent object attribute value, updating the persistent object attribute value to provide an updated persistent object attribute value, unmarshaling the updated persistent object attribute value from the marshal buffer to provide a decoded updated persistent object attribute value, and writing the decoded updated persistent object attribute value to the data store. In another aspect of the invention, a method for writing decoded updated persistent object attribute values to the data store includes extracting an index of persistent object attributes stored in the data structure, finding the location of the persistent object attribute in the data base, adding the persistent object attribute to the data store if the persistent object attribute cannot be found in the index, and writing the persistent object attribute value to the data store at the location corresponding to the persistent object attribute.
