integration of heterogeneous database Integration, and data inconsistencies during data integration index terms-heterogeneous databases, integrated databases, schema integration, semantic incompatibilities.

The integration of distributed, heterogeneous databases, sometimes called data integration, is an active area of re- search [14 27 2 19 40 61. Data integration has been applied in many fields however, there is limited application in the health sector the topic of heterogeneous database integration is difficult but still important in bioinformatics[3]there are many reasons for the limitation including, inherent complexity of database inconsistent with information in another. Data integration systems are formally defined as a triple ,, where is the global (or mediated) schema, is the heterogeneous set of source schemas, and is the mapping that maps queries between the source and the global schemas.

Integration, and data inconsistencies during data integration index terms-heterogeneous databases, integrated databases, schema integration, semantic incompatibilities i introduction he problem of integrating disparate information systems has been investigated by a number of researchers [1]-[17], and examples of prototypes include multibase. Namely the integration of two heterogeneous vector data sets, and the integration of raster and vector data both algorithms are linked to a federated database which allows for automatic object matching and for managing n:m relationships. A heterogeneous database system is an automated system for the integration of heterogeneous, disparate database management systems to present a user with a single, unified query interface heterogeneous database systems are computational models and software implementations that provide heterogeneous database integration.

Heterogeneous system usually result when individual sites have implemented their own database and integration is considered at a later stage in a heterogeneous system, translations are required to allow communication between different dbmss. Understanding complex relationships among heterogeneous biological data is one of the fundamental goals in biology in most cases, diverse biological data are stored in relational databases, such as mysql and oracle, which store data in multiple tables and then infer relationships by multiple-join statements.

Integration problem of heterogeneous data sources, and the thrust of our research, is to provide access to a possibly large number of information agents that dynamically or. Full-text paper (pdf): heterogeneous database integration using agent-oriented information systems.

Heterogeneous database integration is critical in biomedical discovery (lacroix and critchlow, 2003) heterogeneous database integration is a challenging topic, important in several application domains (karasavvas et al 2004), and is one of the most important computer science problems today (zhou et al 1995. Resource integration of heterogeneous database interoperability federated database 1 introduction heterogeneous database interoperability issues as a database research in the field hot and difficult issues at home and abroad, academic and industrial sectors have attracted wide attention.
