We performed a comparison between Oracle Exadata and Teradata based on our users’ reviews in five categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: Teradata has a slight edge in this comparison since it received slightly higher marks in the Ease of Deployment category.
"Compression is a great feature, where one can really save a lot of storage."
"The storage capacity and the performance of Oracle Exadata are good. When comparing the performance to other technologies it is very good. I am satisfied with the management of the solution."
"The performance on the databases is good."
"Oracle Exadata has very good hardware."
"It has improved the performance, now we run with more performance cores with less CPU to attend all the database demands. Reducing Time to Market, increase our ability to face the competition with speed and low cost."
"The most valuable feature is that you have the same familiar environment of an Oracle database but with the additional performance you get from this architecture."
"It is the best solution for OLTP and data warehousing."
"A very stable solution, which we have hardly any problems with."
"It is a solid database a lot of different tools to move data."
"Teradata's pretty fast."
"We did performance testing. We had a set of real life MicroStrategy reports. Our conditions were: Not allowed to redesign data model, not allowed to rewrite the queries, all queries should be generated by MicroStrategy, no aggregates. Teradata appeared to be way faster than a similarly configured (in terms of hardware) Oracle server."
"A conventional and easily defined way to build a data warehouse or a layer of data marts."
"The functionality of the solution is excellent."
"The most valuable features of Teradata are that it is a massively parallel platform and I can receive a lot of data and get the queries out correctly, especially if it's been appropriately designed. The native features make it very suitable for multiple large data tasks in a structured data environment. Additionally, the automation is very good."
"Building a data warehouse with Teradata has definitely helped a lot of our downstream applications to more easily access information."
"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."
"I would like to see more database features and maybe more archiving features, because we need to do data archiving."
"It would be nice to have a single click button to, say, migrate my VMware VM into the Oracle VM, or vice-versa."
"It's too expensive per terabyte. It's complex."
"License or upgrade management can be difficult and time consuming because it requires login to a separate console."
"There is room for improvement with the handling of the Temp IO, which is often used for JOIN statements."
"I liked Spark, but it was discontinued when Exadata L6 came back. I loved it, and I wish they would bring back Spark integration."
"Since the product is an appliance, it is very costly."
"Checking the Smart Scan issues is complicated."
"Query language and its functionality are rather limited, compared to Oracle or even SQL Server. However, it is possible to perform any kind of logic in it (though some workarounds may be required)."
"Teradata is a bit late for the cloud."
"I think the UI is not there yet. It could be improved by being more user-friendly."
"Teradata needs to expand the kind of training that's available to customers. Teradata only offers training directly and doesn't delegate to any third-party companies. As a result, it's harder to find people trained on Teradata in our market relative to Oracle."
"Teradata's UI could be more user-friendly."
"The capability to implement it with comparable performance across various private cloud environments, ensuring adaptability to different infrastructure setups would be beneficial."
"An additional feature I would you like to see included in the next release, is that it needs to be more cloud-friendly."
"The following could be better: licensing, architecture openness, integration with other tools."
