(English Abstract)
Shortest path search is a major topic in various domains that can be represented by graphs such as traffic information, navigation and computer network. As we approach the age of big data, these graph data and information are getting larger and larger in size compared to the past. Therefore, there is the need to effectively search and analyze large graph data. In order to solve this problem, there have been several researches on graph analysis directly in the database. In this study, an In-RDBMS ALT algorithm(A* algorithm, Landmark, Triangle Inequality) that heuristically searches the shortest paths directly in relational database is proposed. The efficiency of In-RDBMS ALT algorithm is also discussed through comparison with existing In-RDBMS shortest path search algorithm.
