When we invest in technology solutions we expect improvement in productivity, agility, performance and more. We don’t want to be limited by the technology we select. While data warehouses are designed to give us the freedom to access complete and reliable information, the underlying data integration architecture and the type of solution used can lead to significant constraints on how we manage our critical production systems.
With data warehousing solutions, one of the most common constraints is the time window available for batch extract processing on the source systems. The resource intensive extract process typically has to be done in off-business hours and restricts access to critical source systems.
A low-impact, real-time data integration solution can liberate your systems from batch windows. When the extract component uses a non-intrusive method, such as reading database transaction logs to capture only the changed data, it does not burden source systems. Hence, data extract can happen at any time of the day, and throughout the day, while all users are online.
SunGard is a great example for achieving a major transformation in data warehousing solutions by using log-based real-time data integration. The company removed batch processing timeline related constraint by using Oracle GoldenGate to capture all of the intraday changes that take place on the selected tables. As a result they reduced the nightly extract process from the Oracle E-Business Suite application by 9 hours. In addition, Oracle GoldenGate enables to feed EBusiness Suite data to the Oracle BI Application for Finance throughout the day. Hence, end users have access to up-to-date information on the Oracle Business Intelligence dashboards as changes occur.
To read more about how real-time data integration can free your critical systems from batch window constraints and how SunGard leveraged Oracle GoldenGate in their data warehousing implementation, I invite you to check out the SunGard case study and the article “Freedom from Batch Windows Using Real-Time Data Integration” we wrote for TDWI's What Works in Emerging Technologies publication. As always, you can find more resources on Oracle GoldenGate on our recently redesigned website.
