Using XML technology for the ontology-based semantic integration of life science databases

Area of Science:

• Life Sciences
• Bioinformatics
• Database Management

Background:

• Numerous life science databases exist online, posing integration challenges due to heterogeneity.
• Answering complex biological questions requires integrating these diverse data sources.
• Extensible Markup Language (XML) is increasingly adopted for data exchange in life sciences.

Purpose of the Study:

• To present an ontology-driven data integration architecture using XML technology.
• To address challenges in large-scale life science database integration.
• To demonstrate a practical implementation for real-world scenarios.

Main Methods:

• Developed a general architecture for ontology-driven data integration.
• Utilized extensible markup language (XML) for data representation and exchange.
• Implemented a prototype using a native XML database and an expert system shell.

Main Results:

• The proposed architecture effectively overcomes traditional database integration problems.
• Demonstrated a proof-of-concept for a real-world integration scenario.
• Showcased the utility of XML technology in life science data integration.

Conclusions:

• Ontology-driven integration using XML offers a robust solution for life science databases.
• The implemented prototype validates the architecture's effectiveness.
• This approach facilitates answering complex biological questions through integrated data.
