The Information Service is a fundamental component in a grid environment. It has to meet a lot of requirements such as access to static and dynamic information related to grid resources, efficient and secure access to dynamic data, decentralized maintenance, fault tolerance etc., in order to achieve better performance, scalability, security and extensibility. Currently there are two different major approaches. One is based on a directory infrastructure and another one on a novel approach that exploits a relational DBMS. In this paper we present a performance comparison analysis between Grid Resource Information Service (GRIS) and Local Dynamic Grid Catalog relational information service (LDGC), providing also information about two projects (iGrid and Grid Relational Catalog) in the grid data management area.
