Model-independent schema translation

Model-Independent Schema and Data Translation

We describe MIDST, an implementation of the model management operator ModelGen, which translates schemas from one model to another, for example from OO to SQL or from SQL to XSD. It extends past approaches by translating database instances, not just their schemas. The operator can be used to generate database wrappers (e.g. OO or XML to relational), default user interfaces (e.g. relational to f...

Model Independent Schema and Data Translation (Extended abstract)

A runtime approach to model-generic schema and data translation is proposed. It is based on our previous work on MIDST, a platform conceived to perform translations in an off-line fashion. In the original approach, the source database is imported into MIDST dictionary, where it is stored according to a universal model. Then the translation is applied within the tool as a composition of elementa...

From Schema and Model Translation to a Model Management System

Model management addresses problems dealing with forms of collaboration among heterogeneous databases. This collaboration may include exchange of data, schema integration, synchronization, translation and, in general, any issue characterized by a data evolving scenario. It provides a structured framework allowing standard solutions to data programmability problems in terms of the application of...

Schema Independent

XML has become the standard way for representing and transforming data over the World Wide Web. The problem with XML documents is that they have a very high ratio of redundancy, which makes these documents demanding a large storage capacity and large network band-width for transmission. This study designs a system for compressing and querying XML documents (XMLCQ) which compresses the XML docum...
