Xross Technology Basics

In many real-world, data-intensive applications, PL/SQL can process data significantly faster than Java-often by a factor of 2x to 10x. If a Java implementation requires many database round trips, the performance advantage can be even higher (in some cases up to 100x). For workloads with many consecutive reads and writes, bundling multiple operations into fewer database calls reduces round trips, lowers latency, and improves overall throughput.

Xross-technology integration between PL/SQL and Java lets you combine the strengths of both platforms: PL/SQL executes database-side logic efficiently, while Java provides robust application features, integrations, and tooling. The result is a clean split: heavy data processing stays close to the data, and application orchestration stays in Java.

This Integration Enables

  1. Direct, high-performance calls from Java to PL/SQL using Oracle JDBC extensions.
  2. Simpler data exchange through strongly typed transfer objects.
  3. Automated code generation for consistent, type-safe connectivity.
  4. Support for complex Oracle data types beyond what many generic persistence frameworks typically cover.
  5. Fewer database round trips and reduced data transfer between application and database.
  6. Efficient bidirectional transformations, aggregation, bulk processing, and analytics for demanding use cases such as ETL jobs, reporting, batch workloads, and business intelligence.
