“…For example, suppose that we have a user who expresses a request in order to merge two models into one. To achieve this, most of the model-based approaches such in [12], [13] and [14], use development models by putting the system offline, at first. Then they specify a set of correspondence or composition rules generally using the respective metamodels of the two input models.…”

Abstract-The development of complex software systems is more and more based on the composition and integration of autonomous component systems. This can be done either statically (proactive approach) at development-time or dynamically through a reactive approach in which a new composite system can possibly be created on-demand and/or at run-time from existing systems. With the aim of constructing and managing such complex and reactive software systems, we propose a megamodelbased environment supporting dynamic tool integration. Such an environment must therefore be consistent at any time (i.e. before, during and after an integration) and should also have to exhibit some self-* properties (such self management, selfhealing and self-configuration). In order to meet these challenges we propose the use of Hoare's Axiomatic Semantics and some inference rules to maintain the integrity of the megamodel and its components. For that we have defined a formal-safe execution as well as an execution semantic for each operation likely to modify the megamodel contents.

“…The presented model-based approaches ( [12], [13] and [14]) solve the problem of integration of software components by using the first solution through the use of development models, therefore such approaches can be considered as proactive integration. But we found no approach carrying out this problem using runtime models.…”

“…Indeed, as our dictionary includes also a data level (as illustrated in a previous paper of ours [2]), which lists all data items that instantiate a given construct, it is interesting to see how the operator could be specified in such a way that the result is a schema, as we saw above, together with the associated data. While working at modelgen, we tackled the same issue, and we developed a technique that generated data level Datalog programs out of schema level ones [3].…”

Abstract. Model management is a metadata-based approach to database problems aimed at supporting the productivity of developers by providing schema manipulation operators. Here we propose MISM (Model Independent Schema Management), a platform for model management offering a set of operators to manipulate schemas, in a manner that is both model-independent (in the sense that operators are generic and apply to schemas of different data models) and model-aware (in the sense that it is possible to say whether a schema is allowed for a data model). This is the first proposal for model management in this direction. We consider the main operators in model management: merge, diff, and modelgen. These operators play a major role in solving various problems related to schema evolution (such as data integration, data exchange or forward engineering), and we show in detail a solution to a major representative of the class, the round-trip engineering problem.

Abstract. 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 forms), or default database schemas from other representations. The approach translates both schemas and data: given a source instance I of a schema S expressed in a source model, and a target model TM, it generates a schema S expressed in TM that is "equivalent" to S and an instance I of S "equivalent" to I. A wide family of models is handled by using a metamodel in which models can be succinctly and precisely described. The approach expresses the translation as Datalog rules and exposes the source and target of the translation in a generic relational dictionary. This makes the translation transparent, easy to customize and model-independent.
