Abstract
When applications must keep their data structures persistent, additional effort beyond transient modeling is necessary to realize suitable persistent storage. The most convenient approach is the use of a persistent programming language (PPL), which offers internal mechanisms for storing and loading data transparently for the application programmer. An alternative to a PPL is a universal programming language that has been extended by persistence concepts for any data types
This paper introduces an extended generic mechanism that abstracts necessary functionality for realizing persistence of any C++ object structure. First, we discuss general problems of persistent storage and the motivation for this approach. The design aspects and the reasons for special features are described in detail with the data and implementation insides. Finally, we sketch the persistent data structure and present the integration of the library in three different example programs.
