Using Database System Designed to Diagnosis Engine Cars Error Working

This work presents a design and implementation of Database System for Vehicle Fault Diagnosis using mix of many knowledge representation forms. The scheme for knowledge representation uses both procedural and declarative knowledge representation formalisms through the application of relational database. So the rule base, case base and frame base formats have been converted into tables. The scheme facilitates combination of forward and backward chaining reasoning, using the problem reduction method for solving problem, and the heuristic search technique. All the editing facilities of system; inserting, deleting and updating of a rule, case, and frame are present. In this work, visual studio 2008 (VB.Net) have been used for the implementation of the system and suitable user interface design. The implementation is an application for the system in the domain vehicle fault diagnosis. Therefore, the Database System for Diagnosis engine cars error working tested for many cases and the results, from different cases, matched the results of the vehicle mechanic.
