ABSTRACT
Object models of planning applications are very complex, huge and individually structured. Complexity increases, if they are versioned for distributed processing. This chapter proposes a persistence concept for such purposes. It describes the general structure of object oriented planning application model. This is the base for the persistence mechanism. Generally, queries against the data store are generated from feature logic terms with the help of a interpreter. The feature logic persistence schema is tuned for that purpose. The chapter discusses the advantages and disadvantages of the feature logic persistence schema. For the access to the object’s attributes the wrapper concept in combination with the interface concept is used. Thus, it supports existing objects as well as new designed objects.
