An Efficient Implementation of Persistent Objects
Persistent objects form a general and very useful method for storing internal program data between executions of a program. And as points out, Ada is an excellent language for implementing persistent objects. This paper introduces a low-impact, efficient implementation of persistent objects based on storage pools and the “POSIX.Memory_ Mapping” API . The performance and reliability of the implementation is compared with serialisation.
