Executive SummaryUpdated on Apr 20, 2025

Teradata and IBM Db2 Warehouse are leading solutions in the data warehousing market. Teradata holds an advantage in performance with its speed and analytical functions, while IBM Db2 Warehouse is known for its integration capabilities and reliable handling of large data volumes.

Features: Teradata is recognized for its parallel processing abilities, shared-nothing architecture, and strong performance in complex queries. It offers Massive Parallel Processing, efficient query execution, and good scalability. IBM Db2 Warehouse provides powerful data handling, efficient ETL, and analytics, with strong stability and security for large data processing.

Room for Improvement: Teradata users suggest enhanced cloud options, a more intuitive user interface, and broader platform integration. Pricing models and support for unstructured data are also concerns. IBM Db2 Warehouse is noted for limited documentation, interface challenges, and slower support responses. Improvements in scalability and deeper analytics integration are desired.

Ease of Deployment and Customer Service: Teradata offers extensive deployment across public, private, and hybrid clouds, praised for its adaptability. Its technical support is acknowledged for professionalism, though response times are sometimes slow. IBM Db2 Warehouse supports versatile deployment but lacks Teradata's flexibility in cloud integration. IBM's support is competent but is often critiqued for slower response times than Teradata.

Pricing and ROI: Teradata is criticized for high pricing, although its performance often justifies the cost. Its flexible pricing and subscription models are noted, yet high license fees can be a barrier for smaller companies. IBM Db2 Warehouse is also costly, with feedback highlighting its expense against competitors like Oracle. Both products deliver ROI through customer satisfaction and enhanced analytics, though high costs remain a common discussion point.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"IBM Db2 Warehouse is more resilient when dealing with business intelligence applications."

"The solution is stable."

"Provides good security and reliability."

"I think it scales really well and as long as you take enough time to learn a little bit about it, it works really well."

"The most valuable features of IBM Db2 Warehouse include its availability, easy integration, ability to deal with a large size of data, excellent performance with no delays, powerful security mechanisms, and effective support."

"The analytics engine is not bad at forecasting predictions."

"IBM Db2 Warehouse is more resilient when dealing with business intelligence applications."

"It can scale effectively as long as resources are available."

More IBM Db2 Warehouse pros

"The key advantages are Performance when processing Terabytes of data and scalability."

"Improved performance of ETL procedures, reporting."

"Their extensive experience in data warehousing, the platform's performance, and their strong reputation in the market are the most valuable."

"It's the same as your visual database. I like the fast load feature for data, the BTQ solution is very good, and storage procedures are very fast."

"The performance is great, we are able to query our data in one operation."

"It's stable and reliable."

"Teradata can be deployed on-premise, on the cloud, or in a virtual machine, which means customers can move without having to create their architecture all over again."

"It is very stable. It's 100% uptime. Speed and resilience are one of the greatest features of this product. In almost twenty years we've never had downtime, except for outages for patches and upgrades. We've never had a system failure in twenty years."

More Teradata pros

Cons

"The biggest challenge anyone could have with Db2 Warehouse is their references or online resources and documentation. They are very, very, very limited on the web."

"The primary challenges customers face with IBM Db2 Warehouse are related to its complexity in usage. It requires highly skilled professionals who understand Db2, and both training and support are challenging to obtain."

"Lacks sufficient documentation and particularly in Spanish."

"The biggest problems we have is when the backup solution is failing or slow and we run out of log space, which has happened probably a couple of times in the last four years."

"It takes a long time to have a new version or release, similar to Oracle."

"In terms of improvement, IBM Db2 Warehouse should be more scalable."

"There should be more material available for training and training should be free."

"Responding to support tickets takes a lot of time. It can range from two to four days, even for critical issues."

More IBM Db2 Warehouse cons

"Since I was working on the very basic, legacy systems, the memory thing was always a challenge. If Teradata is moving to the cloud, the space constraint or the memory issue that my company generally faces will eventually resolve, in time. What I'd like to see in the next release of Teradata is that it becomes full-fledged on the cloud, apart from better connectivity to various systems. For example, if I have to read or include a Python script, if I write some basic codes, I should be able to read even unstructured data. I know that it's not supported even in Snowflake, but at least semi-structured data support, if that can be a little more enhanced, that would be good."

"Teradata hardly supports unstructured data or semi-structured data"

"Apart from Control-M, it would be nice if it could integrate with other tools."

"The reporting side wasn't very good in the past, but with the latest versions, it's getting better. Still, the friendliness of the PDC reporting and functionality needs to be improved."

"I've been using the same UI for 20 years in Teradata. It could use some updating. Adding more stability around Teradata Studio would be outstanding. Teradata Studio is a Java-based version of their tool. It's much better now, but it still has some room for improvement."

"There is a need to improve performance in high transaction processes, as well as the reporting system."

"Their level of technical support is adequate. It could be better."

"It's primarily designed for big projects and therefore, the pricing is pretty high. It's not suitable for smaller companies."

More Teradata cons

Pricing and Cost Advice

"In a traditional on-prem database, in a data warehouse, the solution is probably on the expensive side."

"The price of the solution could be reduced, it is expensive."

"Teradata is expensive, so it's typically marketed to big customers. However, there have been some changes, and Teradata is now offering more flexible pricing models and equipment leasing. They've added pay-as-you-go and cloud models, so it's changing, but Teradata is generally known as an expensive high-end product."

"Teradata used to be expensive, but they have been lowering their prices."

"I rate the product price a nine on a scale of one to ten, where one is cheap and ten is expensive."

"In this day and age, we want to get things done quickly. So, we go to the AWS Marketplace."

"It is still a very expensive solution. While I very much like the pure technological supremacy of the software itself, I believe Teradata as a company needs to become more affordable. They are already losing the market to more flexible or cheaper competitors."

"The tool costs about 30,000 euros a month, while Azure Synapse SQL only costs 10,000."

"I am using the free version of Teradata."
