Join this webcast to see how IBM Data Studio Developer and pureQuery can take the pain out of Java data access. uApplications developed using both Java and SQL have become a common requirement. Database connectivity using Java Database Connectivity (JDBC) to create an application is a multi-step tedious process, and tooling that covers both SQL and Java has been unavailable, until now. IBM Data Studio introduces the pureQuery platform: a high-performance, Java data access platform focused on simplifying the tasks of developing, managing, and optimizing database applications and services.
