每种数据库都有自己的应用范围,以电子商务领域而言,J2ee占优势,一般采用的是oracle,不过如果你是微软的拥趸,可以考虑Windows DNA方案,因为SQL是微软的,所以Windows DNA使用SQL.一般来说,初学者使用SQL比较容易入门。毕竟是微软的东东。如果要学Orcale,应该有不少书,我现在正在看《orcale8i初学者指南》

But if you want to use database.Then it depends.To program with java,oracle is the very choice,due to its best performance interacting with java.But to program with c,perhaps mysql is a good choice.And the most popular database is oracle,but now db2 also gain much attention.And for the sake of IBM's great power,db2 will have a bright future.
