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."
"The stability is incredible. I have customers with uptimes of several years."
"The scalability is very good."
"The solution's stability, performance, enhanced functionality, and replication are all great features."
"Replication, all levels of replication, query charting, and the MongoDB embedded are the most valuable features of this solution."
"So far, we do not have a lot of issues. It's pretty problem-free."
"It supports in-house-built applications in .NET and VB6"
"The most valuable feature is concurrency and locking because my customers usually use databases in OLTP mode. So, for a large number of competitive users. Other features that are well valued are quick large-scale data types. It is better than Oracle."
"Things have started moving faster in my company, such as data retrieval happens more quickly.​"
"The most valuable feature is the ease of uploading data from multiple sources."
"It's very, very fast"
"It is a highly robust software solution."
"The solution's banking model, called FSLDM (Financial Services Logical Data Model), is sophisticated and good."
"I found all parts --loading, transformation, processing & querying work in parallel, and end-to-end-- to be valuable."
"The product's scalability is great. Scalability-wise, I rate the solution a ten out of ten."
"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."
 

Cons

"The pricing is a bit expensive."
"The solution lacks some functionality."
"Continue extending the SQL language for compatibility with the competition's language, including Stored Procedure Language."
"There should be more intelligence surrounding discovering data to be able to automatically create indexes."
"I really would love to have a QT plugin."
"The support team could include local engineers to establish efficient communication. It will help us speed up the escalation process."
"The solution really doesn't add new features very often."
"I experienced poor input/output (IO) performance."
"​Their level of technical support is adequate. It could be better.​"
"I would like to see more integration with many different types of data."
"From my perspective, it would be good if they gave better ITIN/R plugins to use the data for AI modeling, or data science modeling. We can do it now; however, it could be more elegant in terms of interfacing."
"There is some improvement required on OLTP level and some analytical function is missing."
"Apart from Control-M, it would be nice if it could integrate with other tools."
"The user interface needs to be improved."
"When backups are performed, it locks the database, preventing user access, which is a concern."
"They should add more connectors to different platforms."
 

Pricing and Cost Advice

"The product has reasonable pricing. We purchase its yearly license."
"For me, it's always too expensive."
"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."
"I am not aware of the licensing costs or terms."
"​When looking into implementing this product, pricing is the main issue followed by technical expertise​."
"The product cost is high for what the client gets. There may be more cost-effective solutions for small and medium-sized organizations."
"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 solution requires a license."
"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."
"I am using the free version of Teradata."
"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."
"We are looking for a more flexible cost model for the next version that we use, whether it be cloud or on-premise."
