In the last 10 years, schema mapping management has become an important research area in data transformation, exchange, and integration systems. The reasons for its success can be found in the declarative nature of its building block (thus enabling clean semantics and easy to use design tools) paired with the efficiency and modularity in the deployment step. In this paper we sketch a line of evolution in schema-mappings and data exchange systems, through what we identify as three main ages. We start presenting the foundations of schema mapping tools and the first tools aimed at translating data from a source to a target schema in the first, heroic age. We then discuss the silver age, when schema mapping tools have grown their way into complex systems and have been translated into both commercial and open-source tools. Finally, we show how recent results in schema-mapping and data-exchange research may be considered the starting point for a forthcoming golden age, with novel research opportunities and a new generation of systems capable of dealing with a significantly larger class of real-life applications.

Abstract
In the last 10 years, schema mapping management has become an important research area in data transformation, exchange, and integration systems. The reasons for its success can be found in the declarative nature of its building block (thus enabling clean semantics and easy to use design tools) paired with the efficiency and modularity in the deployment step. In this paper we sketch a line of evolution in schema-mappings and data exchange systems, through what we identify as three main ages. We start presenting the foundations of schema mapping tools and the first tools aimed at translating data from a source to a target schema in the first, heroic age. We then discuss the silver age, when schema mapping tools have grown their way into complex systems and have been translated into both commercial and open-source tools. Finally, we show how recent results in schema-mapping and data-exchange research may be considered the starting point for a forthcoming golden age, with novel research opportunities and a new generation of systems capable of dealing with a significantly larger class of real-life applications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
