Has offered a cost-effective option despite frequent technical issues and limited market demand
We find some bugs in IBM Informix. Maybe we are using it more aggressively than others. Every month or every second month, we find some bugs in it, which is not ideal. It should be rare, not this frequent. The good thing is they cover those bugs in the next release within weeks or days on demand. IBM Informix should become hybrid and should include AI features similar to other DBMS systems such as Snowflake, Redshift, and DataBricks. This would help its value rise with the market.

Delivers consistent performance and enables advanced analytics across complex data environments
Teradata stands out as a solid platform for managing and analyzing large volumes of data. Its architecture allows information to be processed efficiently while maintaining stable performance, even in highly demanding environments. One of its most notable strengths is the ability to run complex queries at high speed, which is essential for organizations that require timely and reliable analytics. Teradata offers a well-integrated ecosystem that supports working with different types of data and enables scalability as organizational needs grow. Its focus on advanced analytics, integration with modern business intelligence tools, and the ability to operate both on-premise and in the cloud make it a versatile solution for data warehousing and large-scale processing. Teradata's stability, technological maturity, and the availability of strong documentation and best practices are noteworthy. I consider Teradata to be a tool with great potential for any organization looking to enhance its analytical capabilities, optimize data processing, and move toward more data-driven decision-making. Teradata stands out as a solid platform for managing a large volume of data in different projects. Its architecture allows information to be processed efficiently while maintaining stable performance, even in high-demanding environments. A well-integrated AI ecosystem that supports working with different types of data and enables scalability as organizational needs grow across different kinds of enterprises or organizations. The focus on advanced analytics integration with modern business intelligence tools is particularly valuable. Teradata combines a powerful parallel process and optimizing SQL engine with a highly scalable architecture allowing businesses to execute complex queries and analytics in real-time. It supports multi-cloud, hybrid, and on-premise environments, giving organizations flexibility to choose the setup that best aligns with their strategy. One of the biggest strengths is the ability to unify disparate data sources and support high concurrency, enabling different teams, such as analytics, operations, BI, and data science, to access consistent, trusted data across the enterprise.

Quotes from Members

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

Pros

"It supports in-house-built applications in .NET and VB6"
"It supports multiple applications and business intelligence tools."
"Not looking at Informix would really mean a shot in your own leg before walking a long distance."
"We don't have any problems with the Informix Database."
"The scalability is very good."
"Flexible Grid provides the ability to automatically create database objects, such as tables, indexes, and stored procedures on all nodes within the grid as a single operation."
"Replication is a valuable feature and easy to use."
"Overall, this is a great product. It works really well, is very stable, and is very scalable."
"The most valuable feature is the ease of uploading data from multiple sources."
"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."
"Our enterprise data warehouse (EDW) runs on Teradata and it is the single version of truth for management decision-making and reporting."
"It's stable and reliable."
"Teradata appeared to be way faster than a similarly configured (in terms of hardware) Oracle server."
"It is a stable solution. Stability-wise, I rate the solution a nine out of ten."
"It handles large amounts of information with a linear performance increase, in relation to a HW investment."
"I like writing preformance queries for preprocessing on AWS Cloud."
 

Cons

"The support team could include local engineers to establish efficient communication. It will help us speed up the escalation process."
"I experienced poor input/output (IO) performance."
"For me, it's always too expensive. The problem is that Informix sometimes competes with free products, so yes, it's very expensive, but when we're talking about licensed products like SQL Server or anything, the midsize pricing could be significantly improved."
"Informix is very sturdy, but the problem for us is the marketing action around Informix."
"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."
"The solution really doesn't add new features very often. Other solutions are much more actively pushing out upgrades and improvements."
"This solution is in need of more current tools."
"This product could be made easier to use for beginners."
"​The initial setup was complex as we had to rewrite a lot of the code.​"
"The limitation we encountered was related to speed, prompting us to increase our AWS cloud thresholds and benchmarks on the servers, adding more throughput."
"When backups are performed, it locks the database, preventing user access, which is a concern."
"The solution is stable. However, there are times when we are using large amounts of data and we can see some latency issues."
"Teradata's UI could be more user-friendly."
"I was not impressed by tech support. We made several requests regarding performance issues we had with our applications but did not get helpful answers."
"I would like more security and speed."
"Teradata should focus on functionality for building predictive models because, in that regard, it can definitely improve."
 

Pricing and Cost Advice

"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."
"For me, it's always too expensive."
"Price is quite high, so if it is really possible to use other solutions (e.g. you do not have strict requirements for performance and huge data volumes), it might be better to look at alternatives from the RDBMS world."
"The price of Teradata is on the higher side, and I think that it where they lose out on some of their business."
"Teradata is not cheap, but you get what you pay for."
"It's a very expensive product."
"I rate the product price a nine on a scale of one to ten, where one is cheap and ten is expensive."
"Teradata pricing is fine, and it's competitive with all the legacy models. On a scale of one to five, with one being the worst and five being the best, I'm giving Teradata a three, because it can be a little expensive, when compared to other solutions."
"Teradata is a very expensive solution."
"​I would advise others to look into migration and setup as a fixed price and incorporate a SaaS option for other Teradata services​."
