The Best Data Integration for Oracle Exadata Comes from Oracle
By Irem Radzik-Oracle on Jul 26, 2013
In a previous blog post I talked about about how Oracle Exadata customers can migrate/consolidate their systems without downtime. In that blog post I mentioned that Oracle Data Integrator and Oracle GoldenGate offer unique and optimized data integration solutions for Oracle Exadata. For example, customers that choose to feed their data warehouse or reporting database with near real-time throughout the day, can do so without decreasing performance or availability of source and target systems. And if you ask why real-time, the short answer is: in today’s fast-paced, always-on world, business decisions need to use more relevant, timely data to be able to act fast and seize opportunities. A longer response to "why real-time" question can be found in a related blog post.
If we look at the solution architecture, as shown on the diagram below, Oracle Data
Integrator and Oracle GoldenGate are both uniquely designed to take full
advantage of the power of the database and to eliminate unnecessary middle-tier
components. Oracle Data
Integrator (ODI) is the best bulk data loading solution for Exadata. ODI is the only ETL platform that can
leverage the full power of Exadata, integrate directly on the Exadata machine
without any additional hardware, and by far provides the simplest setup and
fastest overall performance on an Exadata system.
We regularly see customers achieving a 5-10 times boost when they move their ETL to ODI on Exadata. For some companies the performance gain is even much higher. For example a large insurance company did a proof of concept comparing ODI vs a traditional ETL tool (one of the market leaders) on Exadata. The same process that was taking 5hrs and 11 minutes to complete using the competing ETL product took 7 minutes and 20 seconds with ODI. Oracle Data Integrator was 42 times faster than the conventional ETL when running on Exadata.This shows that Oracle's own data integration offering helps you to gain the most out of your Exadata investment with a truly optimized solution.
GoldenGate is the best solution for streaming data from heterogeneous sources into Exadata in real time. Oracle GoldenGate can also be used together with Data Integrator for hybrid use cases that also demand non-invasive capture, high-speed real time replication. Oracle GoldenGate enables real-time data feeds from heterogeneous sources non-invasively, and delivers to the staging area on the target Exadata system. ODI runs directly on Exadata to use the database engine power to perform in-database transformations. Enterprise Data Quality is integrated with Oracle Data integrator and enables ODI to load trusted data into the data warehouse tables. Only Oracle can offer all these technical benefits wrapped into a single intelligence data warehouse solution that runs on Exadata.
Compared to traditional ETL with add-on CDC this solution offers:
- Non-invasive data capture from heterogeneous sources and avoids any performance impact on source
- No mid-tier; set based transformations use database power
- Mini-batches throughout the day –or- bulk processing nightly which means maximum availability for the DW
solution with Enterprise Data Quality enables leveraging trusted data in the data warehouse
In addition to Starwood Hotels and Resorts, Morrison Supermarkets, United Kingdom’s fourth-largest food
retailer, has seen the power of this solution for their new BI platform and shared their story with us. Morrisons needed to analyze data across a large number of manufacturing,
warehousing, retail, and financial applications with the goal to achieve single
view into operations for improved customer service. The retailer deployed Oracle
GoldenGate and Oracle Data Integrator to bring new data into Oracle Exadata in
near real-time and replicate the data into reporting structures within the data
warehouse—extending visibility into operations. Using Oracle's data integration offering for Exadata, Morrisons produced financial reports in seconds, rather than minutes, and improved staff productivity and agility. You
can read more about Morrison’s success story here and hear from Starwood here.
