Why Teradata

Moving On, Moving Up

Migrating to a Teradata system opens the doors to long-term success.

Technical differentiators allow Teradata to do more vs. Oracle in an analytical environment.

Organizations that invest in data warehouse solutions expect an ongoing return. However, many eventually reach a point when their systems simply cannot keep up with their growth and innovation or the demand these challenges bring for more integration, deeper analysis and broader access.

When looking for ways to conquer these issues, many companies running Oracle, Netezza, SQL Server or other database platforms conclude that migrating to a Teradata system is their best option. It lets them maximize analytics capabilities, boost profits, reduce redundancies, save money and safeguard the overall health and success of their organization now and for the future.

Why Change?

The business and technology benefits of migrating to a Teradata system include:

Business advantages:

  • Getting a single view of the business versus a fragmented, distorted view from siloed systems
  • Finding fast answers to complex questions to make immediate business decisions and inform strategic plans
  • Supporting both strategic analysis and day-to-day operations
  • Saving time and money

Technology advantages:

  • Increasing scalability
  • Boosting flexibility and performance
  • Achieving greater stability and reliability

Shrinking IT budgets and increased spending oversight mean nobody takes the decision to migrate to a new informa­tion platform lightly. Companies research their options to determine the best choice for integrating, accessing and analyzing data—and staying competitive long term. When research reveals that switching to a Teradata system can meet their needs and provide benefits without disrupting daily operations, the choice to migrate becomes clear.

3 Key Reasons to Switch to Teradata


Reduced system complexity and information load times mean more people get better information faster.


Fewer people are required to maintain and manage the system, saving money on staffing and freeing up resources for other projects.


Getting the information you need when you need it enables smarter strategic decisions across the enterprise, enabling faster growth and increased profits.

Head to Head

Even with their latest products, Teradata’s competitors fall short in key performance areas in which Teradata has always excelled. For example, although Oracle has made improvements in its data­base management tools in version 11g database, the product is still, at its core, an online transaction processing (OLTP) database platform that’s not architected specifically for data warehousing. (See graphic above.)

Oracle’s newest tools do little to elimi­nate the management complexity within a data warehouse environment, and the new Exadata platform adds another level of intricacy to be managed. The result is the number of analysts and database administrators (DBAs) required to maintain an Oracle environment—and subsequently, the total cost of ownership (TCO)—is much higher than with a Teradata system.

Additionally, Oracle customers often report that their data warehousing efforts are hampered because:

  • Queries must be carefully planned and scheduled
  • Ad hoc questions and short tactical questions cannot be answered at the same time
  • The number and complexity of questions are limited

A Teradata environment will accommo­date any question at any time so business users can get the timely strategic and operational answers they need without waiting hours or even days.

Users of other competitive systems cite shortcomings as well. Netezza, an IBM Company, claims the ability to scan the entire data warehouse, but fails to deliver the query speed and mixed-workload flex­ibility to put business intelligence (BI) in the hands of employees across the enterprise—not just IT specialists. And Netezza and SQL Server systems cannot handle companies’ exponentially increasing data volumes or their greater need for real-time granular data the way a data warehouse from Teradata can.

Real-World Results

Teradata has successfully migrated more than 400 com­panies in a variety of industries and geographies to its data warehouse from Oracle and other platforms. Here are two examples:


    Business problem: The existing data warehouse was performing poorly; because it could not complete nightly data loads, business users did not have the information they needed to do their jobs ef­fectively and meet service level agreements (SLAs). There was no confidence that the existing environment could accommodate plans for a large loyalty system project or the implementation of integrated marketing tools.

    Reasons for choosing Teradata: Research and evaluation of competi­tive products showed Teradata offered the best choice for user and equipment scalability, easy tool integration, query flexibility, consistent performance and data integrity, and the availability of a proven, rapid migration process.

    Post-migration benefits: Query turnaround time was reduced—in some instances from hours to minutes—thus improving overall opera­tional efficiency. The enhanced infrastructure enabled the company to successfully complete a critical revamping of its loyalty program, giving business users faster access to better sales and marketing data, which helped increase its competitive edge.


    Business problem: The existing information platform made it nearly impossible to report nationally syndicated retail prescription and sales data. The company needed a solution with the power to store and manage ever-increasing amounts of data while providing users with access to more accurate and granular information.

    Reasons for choosing Teradata: Only Teradata could provide a cost-effective system with sufficient responsiveness to enable the pharma­ceutical firm to effectively integrate sales, marketing and finance.

    Post-migration benefits: Eliminating redundancies through informa­tion integration decreased 20TB of data down to 1.2TB. Loading data now takes hours instead of weeks, and queries take minutes instead of hours, freeing up database administrators for other tasks and boosting the productivity of employees at all levels of the organization.

Plan for Long-Term Success

More and more companies are realizing the shortcomings of other systems and making the switch from their existing data ware­house to a Teradata platform to achieve better performance and long-term strategic optimization. Teradata offers a complete, robust, repeatable methodology that can help companies optimize their migration strategy and create a smooth transition for their entire organization.
