摘要：
In this paper we continue the development of partitioning application presented in [13] using JDBC and SQLJ in the ORACLE DBMS. Both APIs are compared by showing specific characteristics, the advantages of connecting to the database through them. The application will calculate the best partitioning scheme using vertical fragmentation and fragment allocation then obtained, in effective places of network. We use a previously implemented algorithm that calculate the local data and remote data accessing cost, and then get the best fragmentation scheme by selecting the lowest cost.
