Quotes from Members

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

Pros

"This solution has made financial reporting possible by allowing financial people the opportunity to set Informix to "Auto Pilot" so that they can attend other duties."
"For IoT business cases, having Informix Enterprise Edition work on edge computers, like Raspberry Pi and using Informix replication, makes complex situations simple to build and maintain."
"So far, we do not have a lot of issues. It's pretty problem-free."
"Every version is faster than the previous."
"Replication is a valuable feature and easy to use."
"The solution's stability, performance, enhanced functionality, and replication are all great features."
"The stability is incredible. I have customers with uptimes of several years."
"The initial setup is pretty easy."
"The initial setup was straightforward."
"The most valuable features are the Shared-nothing architecture and data protection functionality."
"The most valuable feature of Teradata is the quick processing of large data."
"The most valuable feature of Teradata is security. It runs on Unix and Linux platforms which provide better security."
"The product is reliable."
"The feature that we find most valuable is its ability to perform Massive Parallel Processing."
"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 effectively has allowed us to remove over 20 portion copies of the data sets on other DB platforms for real-time operational reporting purposes."
 

Cons

"In my opinion, the packages could be improved. The version I use doesn't allow for packages. I can do some general procedures, but no packages like in Oracle. So, develop separate modules in SQL language. This would be most beneficial for me."
"There should be more intelligence surrounding discovering data to be able to automatically create indexes."
"The solution really doesn't add new features very often."
"The support team could include local engineers to establish efficient communication. It will help us speed up the escalation process."
"Continue extending the SQL language for compatibility with the competition's language, including Stored Procedure Language."
"I experienced poor input/output (IO) performance."
"I really would love to have a QT plugin."
"The technical support services need substantial improvement."
"Needs compatibility with more Big Data platforms."
"They should add more connectors to different platforms."
"The solution could improve by having a cloud version or a cloud component. We have to use other solutions, such as Amazon AWS, Microsoft Azure, or Snowflake for the cloud."
"We tried to use case Teradata for a data warehouse system, but we had some problems in relation to the Teradata system, CDC tools, and source databases. We were unable to transfer data from HPE Integrity mainframe to Teradata."
"Teradata has a few AI models, but in data science, we need more flexibility."
"The solution is stable. However, there are times when we are using large amounts of data and we can see some latency issues."
"Limited interest and success in some areas make us hesitate about upgrading."
"​Their level of technical support is adequate. It could be better.​"
 

Pricing and Cost Advice

"For me, it's always too expensive."
"The product has reasonable pricing. We purchase its yearly license."
"I am not aware of the licensing costs or terms."
"The free edition can be enough to handle moderate-size implementations, but you may want a pay for edition to benefit from more functionality, such as replication."
"In the past, it turned out that other solutions, in order to provide the full range of abilities that the Teradata platform provides plus the migration costs, would end up costing more than Teradata does."
"The cost is significantly high."
"The price of Teradata is on the higher side, and I think that it where they lose out on some of their business."
"We are looking for a more flexible cost model for the next version that we use, whether it be cloud or on-premise."
"It comes at a notably high cost for what it offers."
"The price of Teradata is expensive. However, what they deliver they are outstanding. If you're looking for an inexpensive solution to run a database, this isn't your tool. It's the Ferrari of databases for data warehousing."
"Teradata is not cheap, but you get what you pay for."
"Teradata's licensing is on the expensive side."
