A deductive object-oriented language for integrated genome databases

We developed a deductive object-oriented language for flexible genome analysis, and implemented it on an object-oriented database for genome data. The language does not support method and class definitions. Therefore, object-oriented features, such as inheritance and override, depend on the OODB and the language can be used to call methods from the OODB and to search for objects. It provides simple and powerful ways of searching for objects, and building and testing biological hypotheses. Various works are still required in the future. For example, we must develop a framework for storing rules and their results in the OODB so that we can reuse them to acquire new knowledge. It is difficult to manage data that include errors and duplication by only using the current OODB technique. Developing a technique for the efficient management of those data is another open problem.<>
