Recent advances in laboratory technology have resulted in massive amounts of biological data that are often deposited in web databases. Clearly, access to this data is very important to biological researchers. However, heterogeneity among biological databases due to the incompatibilities in data formats, data representations, and data source schema has impeded the accessibility to these databases. Each of the biological databases has its own interfaces and control languages, and represents information using conflicting data models and formats. The goal of the proposed system is to hide the large variety of local or remote biological databases and the disparity of their interfaces. A user should see only one interface and be able to query the system by specifying what it wants to know without a detailed knowledge where relevant information is located, what its representation is like, and how the biological databases interfaces must be handled.
A promising approach to this problem is to provide access to the large number of biological data sources through a multiagent technology, where a set of agents can cooperate with each other to retrieve relevant information from different biological web databases. The proposed system uses a mediator based integration approach with domain ontology which used as a global schema. The proposed system is developed using JADE (Java Agent DEvelopment Framework) which is a software development framework aimed at developing multi-agent systems and applications conforming to FIPA (Foundation for Intelligent Physical Agent) standards for intelligent. In this work, a multiagent system that responds to different user queries to multiple heterogeneous biological databases was developed. The system works as a middleware between users and different biological databases.
