“…Although these criteria are based on the criteria created for schema integration, the authors modified them to a specifically created hierarchical structure. Later work by the same authors (Madria et al 2008) modified these criteria to known criteria in the literature such as completeness and correctness (the integrated schema must contain all concepts presented in any component schema correctly; the integrated schema must be a representative of the union of the application domains associated with the schemas), minimality (if the same concept appears in more than one component schema, it must occur only once in the integrated schema), and understandability (the integrated schema should be easy to be understood by the designer and the end user; this implies that among the several possible representations of the results of integration allowed by a data model, the one that is most easily understandable should be chosen). The same definitions may be found in many works; for example, Schmitt and Saake (2005) and Batini et al (1986).…”

The process of integrating data in a hierarchical structure is usually based on algorithms designed for one specific task; for example, for eXtendable Markup Language (XML) schema integration. In this article, a more general approach for integration of data in a hierarchical structure is proposed using a generalized tree structure called a complex tree. For this aim we define a set of criteria for integration. These criteria are completeness, precision, and optimality. A simple algorithm based on these criteria is presented and the advantages of the approach are discussed.

Within the frame of an approach to information integration an extensible canonical model is created. A principle of kernel extension of canonical model is proposed. In order to create the justifiable data model mapping for heterogeneous databases integration, concept of data model has been formalized by means of the AMN (Abstract Machine Notation) formalism. For each source model we create a reversible mapping into an extension of the canonical model. The Btechnology is used to prove that the AMN semantics of the source model represents a refinement of the AMN semantics of the extended canonical model. Hereby, the correctness of mapping and the ability to use extended canonical model for representation of the source model schemas are proved. AMN-machines for the canonical and relational data models and relational refinement of the canonical model have been created.

-Ancient Chinese architecture was digitalized preserved in the projects funded by the government in the past few years. Many application systems have been built in order to use these digital resources effectively. In this paper, we investigate a practical framework for data exchange and sharing among heterogeneous databases of these systems. An XML-based metadata is proposed as a standard for data representation and exchange. And a data exchange model is presented. An application system using the proposed model has been developed. It has been proved that the model works well.
