However, removing data from a database system is not a straightforward task; data degradation has an impact on the storage structure, indexing, transaction management, and logging mechanisms. To show the feasibility of data degradation, we provide several techniques to implement it; mainly, a combination of keeping data sorted on degradation time and using encryption techniques where possible. The techniques are founded with a prototype implementation and a theoretical analysis...
