Résumé du livre
We identify different kinds of compositions and give formal synchronization rules between a composition and its components to induce the desired behavior of these compositions in a database setting. Further we argue that the support for handling temporal information provided by other systems addresses only one of two important kinds of historical information. We describe the notions of temporal history and edit history. Finally we address the problem of maintaining consistent historical information of a composition using the historical information of its components. This problem occurs as a result of sharing objects between several compositions. We propose a solution in the LINCKS system."
