Its data management capabilities include data quality, data integration, data architecture, modeling, and data security, which are very important for data-driven companies.

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"
"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."
"It supports multiple applications and business intelligence tools."
"Replication, all levels of replication, query charting, and the MongoDB embedded are the most valuable features of this solution."
"IBM Informix benefits users with high availability and good integration capabilities."
"The stability is incredible. I have customers with uptimes of several years."
"Replication is a valuable feature and easy to use."
"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."
"It is a reliable database warehouse solution that is transparent to the end user."
"When we are not able to solve a problem we immediately contacted Oracle support team to help us solve it."
"It is reliable. It's very stable."
"The scalability is quite good."
"The solution is very stable with the performance being very reliable."
"Oracle Database is running on the same old hardware that I had the 11g version on and it is operating faster. It seems to be really good. It's fast even when the workload is heavy, easy to do backups and other administrative tasks with the Enterprise Manager."
"A scalable solution with straightforward initial setup."
"It's fast compared to other databases."
"Intelliflex is very scalable. In fact, scalability has improved 100 times by Intelliflex, in my personal opinion."
"Teradata effectively uses parallelism to the granular level, performing better than other databases."
"Auto-partitioning and indexing, and resource allocation on the fly are key features."
"​Parallel processing features have helped to easily dump any size of data and retrieve data with great performance."
"The most valuable features are the Shared-nothing architecture and data protection functionality."
"Things have started moving faster in my company, such as data retrieval happens more quickly.​"
"IntelliFlex is easy to scale - one of its best features is that you can upscale it to the size you want."
"Teradata's capabilities enhance data management efficiency, support scalability, and contribute to faster query performance."
 

Cons

"This solution is in need of more current tools."
"I would like to see backups from secondary servers."
"I really would love to have a QT plugin."
"The pricing is a bit expensive."
"There should be more intelligence surrounding discovering data to be able to automatically create indexes."
"It would be helpful to have IBM salespeople know that Informix exists, and sell it. Currently, it is completely ignored by IBM."
"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 lacks some functionality."
"The queries performance could improve compared to other products."
"Their local support can be better. Local support is a challenge in Africa for all IT companies."
"We don't really find that any features are lacking."
"I can only remember that setting up Oracle Database was a pain because it uses Java."
"I have contacted the support from Oracle and they are sometimes slow."
"The connection can be slow due to the distance from the provider."
"Oracle is a costly product, and it requires a lot of resources."
"In general, the support is not good since most of the time the person whom you are given to is not so professional."
"The primary challenge with Teradata lies in its cost structure, encompassing subscription fees, software licenses, and hardware expenses."
"It's primarily designed for big projects and therefore, the pricing is pretty high. It's not suitable for smaller companies."
"Teradata could improve by being less complicated. There are some aspects that are not available on the Unix server and a Unix system is required to access some data, such as in case of an emergency."
"The cloud is the new challenge and the new opportunity."
"Data ingestion is done via external utilities and not by the query language itself. It would be more convenient to have that functionality within its SQL dialect."
"Teradata needs to pay attention to the cloud-based solution to make sure it runs smoothly."
"Teradata's UI could be improved."
"The current operational approach needs improvement."
 

Pricing and Cost Advice

"The product has reasonable pricing. We purchase its yearly license."
"For me, it's always too expensive."
"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."
"It is quite expensive."
"Our customers buy licenses from Oracle directly."
"The pricing should be cheaper."
"Oracle Databases license and maintenance prices are too high. The government ministry of finance gives us our budget and this solution is too expensive."
"The license is inexpensive."
"The main issue where I feel that Oracle still has a problem is with the licensing. Licensing is still expensive and the reason why today most startups use other, cheaper databases. Those other databases are much less sophisticated than Oracle."
"The price is very expensive for the support."
"Licensing is on a yearly basis."
"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."
"Teradata is a very expensive solution."
"The price of Teradata could be less expensive."
"The tool costs about 30,000 euros a month, while Azure Synapse SQL only costs 10,000."
"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."
"In this day and age, we want to get things done quickly. So, we go to the AWS Marketplace."
"The cost is significantly high."
"Teradata is currently making improvements in this area."
