Abstract

Strategies developed for database preservation in the past include technology preservation, migration, emulation and the use of a universal virtual computer. In this paper we present a new concept of "Model Migration for Database Preservation". Our proposed approach involves two major activities. First, migrating the database model from conventional relational model to dimensional model and second, calculating the information embedded in code and preserving it instead of preserving the code required to calculate it. This will affect the originality of the database but improve two other characteristics: the information considered relevant is kept in a simple and easier to understand format and the systematic process to preserve the dimensional model is independent of the DBMS details and application logic.
