Featured Reviews

Nasir Niamat - PeerSpot reviewer
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.
Kirk Robinson - PeerSpot reviewer
Has improved data quality, optimized reporting processes, and enabled predictive insights across business units
The limitation we encountered was related to speed, prompting us to increase our AWS cloud thresholds and benchmarks on the servers, adding more throughput. We have been testing that, but speed remains one of our key issues. The integration has been awesome because of the platforms and their usage, and usability is great. The most challenging aspect is finding Teradata resources, so we are focusing on internal training and looking for more Teradata experts. If Teradata could provide a list of certified experts, that would be fantastic. I rated Teradata a nine because the main area for improvement is the bandwidth of resources that could assist us in applying to our projects, specifically more certified and expert resources. The market share of Teradata professionals is limited, creating an issue for us.

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 scalability is very good."
"It is very easy to install IBM Informix, very easy to scale, and support is quite better."
"IBM Informix benefits users with high availability and good integration capabilities."
"It supports multiple applications and business intelligence tools."
"The solution's stability, performance, enhanced functionality, and replication are all great features."
"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."
"Every version is faster than the previous."
"It is a solid database a lot of different tools to move data."
"Viewpoint, the detailed query logs and performance statistics are valuable features."
"Teradata's most valuable feature is that it's easy to use."
"It effectively has allowed us to remove over 20 portion copies of the data sets on other DB platforms for real-time operational reporting purposes."
"The ease of deployment is useful so clients are up and running quickly in comparison to other products."
"Teradata effectively uses parallelism to the granular level, performing better than other databases."
"When it comes to integration, tools like Informatica seamlessly connect with Teradata. We ensure the Teradata database is configured correctly in Informatica, including the proper hostname and properties for the load process. We didn't find any major complexity or issues with integration."
"It is quick, secure, and has less hassles because we don't have to involve our networking team, infrastructure, etc. It is very easy to deploy and make market ready."
 

Cons

"There should be more intelligence surrounding discovering data to be able to automatically create indexes."
"This product could be made easier to use for beginners."
"The support team could include local engineers to establish efficient communication. It will help us speed up the escalation process."
"It would be helpful to have IBM salespeople know that Informix exists, and sell it. Currently, it is completely ignored by IBM."
"The technical support services need substantial improvement."
"Continue extending the SQL language for compatibility with the competition's language, including Stored Procedure Language."
"I experienced poor input/output (IO) performance."
"This solution is in need of more current tools."
"I'm not sure about the unstructured data management capabilities. It could be improved."
"The limitation we encountered was related to speed, prompting us to increase our AWS cloud thresholds and benchmarks on the servers, adding more throughput."
"Teradata hardly supports unstructured data or semi-structured data"
"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 increasing volumes of data demand more and more performance."
"It is hard for some of our users to set up rules for cleansing and transforming data, so this is something that could be improved."
"If I want to implement an upgrade, I'd like to see how it will be different. Ideally, Data Lab should help me test production items and also do future things. Future releases should be downloadable and testable in Data Lab."
"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."
 

Pricing and Cost Advice

"I am not aware of the licensing costs or terms."
"For me, it's always too expensive."
"The product has reasonable pricing. We purchase its yearly license."
"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 comes at a notably high cost for what it offers."
"Make sure you have the in-house skills to design and support the solution, as relying on external sources is extremely costly and tends to lock you into specific platforms, tools, and paradigms."
"The price needs to be more competitive as Hadoop, Redshift, Snowflake, etc are constantly making way into EDW space."
"The price of the solution could be reduced, it is expensive."
"The tool costs about 30,000 euros a month, while Azure Synapse SQL only costs 10,000."
"Users have to pay a yearly licensing fee for Teradata IntelliFlex, which is very expensive."
"The product cost is high for what the client gets. There may be more cost-effective solutions for small and medium-sized organizations."
"The price of Teradata could be less expensive."
