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

"Not looking at Informix would really mean a shot in your own leg before walking a long distance."
"Replication, all levels of replication, query charting, and the MongoDB embedded are the most valuable features of this solution."
"OLTP processing capacity and the availability of information with high availability implementation have been significantly improved."
"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 solution's stability, performance, enhanced functionality, and replication are all great features."
"The solution is quite stable and reliable; we use it mainly due to its general stable nature."
"IBM Informix benefits users with high availability and good integration capabilities."
"The feature that we find most valuable is its ability to perform Massive Parallel Processing."
"I've never had any issues with scalability."
"Our customers are very impressed by Teradata's speed, because it's massively parallel processed."
"Teradata features high productivity and reliability because it has several redundancy options, so the system is always up and running."
"Auto-partitioning and indexing, and resource allocation on the fly are key features."
"The product is reliable."
"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."
"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."
 

Cons

"The product needs a lot more marketing involvement from IBM."
"The solution lacks some functionality."
"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. Other solutions are much more actively pushing out upgrades and improvements."
"Every month or every second month, we find some bugs in it, which is not ideal."
"I experienced poor input/output (IO) performance."
"The solution doesn't include functionality like data anonymization."
"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 scalability could be better. The on-premises solution is always more complicated to scale."
"Teradata's UI could be improved."
"I'd like to see better processing on a transactional level and star schema optimization."
"My experience was the Teradata Solution Architects were less friendly and hid information and charged for simple things."
"GUI of administrative tools is really outdated."
"Teradata has a few AI models, but in data science, we need more flexibility."
"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 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."
 

Pricing and Cost Advice

"The product has reasonable pricing. We purchase its yearly license."
"I am not aware of the licensing costs or terms."
"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."
"The price needs to be more competitive as Hadoop, Redshift, Snowflake, etc are constantly making way into EDW space."
"Teradata is not cheap, but you get what you pay for."
"The cost is substantial, totaling around $1.2 million, solely dedicated to upgrading the hardware."
"It comes at a notably high cost for what it offers."
"The price of the solution could be reduced, it is expensive."
"Teradata is currently making improvements in this area."
"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 cost is significantly high."
