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.

Quotes from Members

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

Pros

"Informix can support huge quantities of data with less memory and less capacity."

"My advice is to take it; you will never regret it."

"It supports in-house-built applications in .NET and VB6"

"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."

"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."

"Overall, this is a great product. It works really well, is very stable, and is very scalable."

"Not looking at Informix would really mean a shot in your own leg before walking a long distance."

More IBM Informix pros

"The cloud is ten times better than physical hardware; it is more cost-effective and the upgrade process is ten times easier."

"It architects the databases well, right from data modelling, the correct appliance to be chosen, the queries hitting the system, strategic and tactical, and that business knowledge should be easy to understand to end developers."

"Teradata's capabilities enhance data management efficiency, support scalability, and contribute to faster query performance."

"Teradata solutions help organizations reduce IT, operations, and maintenance costs; enhance on-time delivery of products and services."

"Teradata effectively uses parallelism to the granular level, performing better than other databases."

"The most valuable feature of Teradata is security. It runs on Unix and Linux platforms which provide better security."

"Teradata has good performance, the response times are very fast. Overall the solution is easy to use. When we do the transformation, we have all of our staging and aggregation data available."

More Teradata pros

Cons

"I really would love to have a QT plugin."

"I would like to see backups from secondary servers."

"The pricing is a bit expensive."

"The solution really doesn't add new features very often. Other solutions are much more actively pushing out upgrades and improvements."

"The solution should offer replication. It would be helpful if the solution would allow us to access third-party tools."

"There should be more intelligence surrounding discovering data to be able to automatically create indexes."

"The solution doesn't include functionality like data anonymization."

"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."

More IBM Informix cons

"The usability could be a bit better. It could be a bit more user-friendly."

"Limited interest and success in some areas make us hesitate about upgrading."

"The primary challenge with Teradata lies in its cost structure, encompassing subscription fees, software licenses, and hardware expenses."

"The tool's flexibility and capacity for expansion are areas of concern where improvements are required."

"My experience was the Teradata Solution Architects were less friendly and hid information and charged for simple things."

"The initial setup was complex as we had to rewrite a lot of the code."

"The increasing volumes of data demand more and more performance."

"The following could be better: licensing, architecture openness, integration with other tools."

More Teradata cons

Pricing and Cost Advice

"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 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 price of Teradata is on the higher side, and I think that it where they lose out on some of their business."

"It's a very expensive product."

"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."

"In this day and age, we want to get things done quickly. So, we go to the AWS Marketplace."

"It comes at a notably high cost for what it offers."

"The cost is substantial, totaling around $1.2 million, solely dedicated to upgrading the hardware."

"The tool costs about 30,000 euros a month, while Azure Synapse SQL only costs 10,000."

"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."
