Harkes, D.C. (author), Visser, Eelco (author)Derived values are values calculated from base values. They can be expressed with views in relational databases, or with expressions in incremental or reactive programming. However, relational views do not provide multiplicity bounds, and incremental and reactive programming require significant boilerplate code in order to encode bidirectional...conference paper 2017

Harkes, D.C. (author), Groenewegen, D.M. (author), Visser, Eelco (author)Derived values are values calculated from base values. They can be expressed in object-oriented languages by means of getters calculating the derived value, and in relational or logic databases by means of (materialized) views. However, switching to a different calculation strategy (for example caching) in object-oriented programming requires...conference paper 2016
