Robust multidimensional database has enabled smooth API integrations and modern data workflows
I think InterSystems IRIS is a continuation of the Caché legacy. Since I have been working with it since 2005 with Caché, I think it is a really amazing tool. It is a very robust and very scalable database. It is very good to work with, and I am already used to working with it. Where it falls a bit short is in the availability of manpower and professionals who work with InterSystems IRIS or Caché. There are few professionals who work with it. Another thing is the cost and the license cost. I think there could be some kind of package that could serve smaller companies and small and medium-sized companies. That would reach a larger slice of the market, because the cost to work with Caché, InterSystems IRIS, and so on is high. I would make this remark about putting together a package and a new product that could serve small and medium-sized companies. The area where InterSystems IRIS falls a bit short is in the cost and the licensing cost. The licensing cost is the main issue I have already mentioned.

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

"My final observation is that everyone should use InterSystems IRIS; it is an amazing tool on the market."
"The best features InterSystems IRIS offers, in my experience, include being a really powerful engine and a really good database."
"In my opinion, the best features that InterSystems IRIS offers are its very optimized database, which I found amazing, and the observability it provides for checking messages and how the data is being transferred, which I find very interesting."
"InterSystems IRIS has had a positive impact on my organization by improving performance and data security."
"The initial setup was straightforward."
"The most important thing we get out of the product is the intelligence that we derive."
"It's very mature from a technology perspective."
"Our enterprise data warehouse (EDW) runs on Teradata and it is the single version of truth for management decision-making and reporting."
"What really impressed me is their approach to design the data warehouse."
"Teradata is expensive but gives value for money, especially if you don't want to move your data to the cloud."
"Improved performance of ETL procedures, reporting."
"Intelliflex is very scalable. In fact, scalability has improved 100 times by Intelliflex, in my personal opinion."
 

Cons

"Python support can be enhanced further, as it's really clunky at the moment, considering that the use of Python is pretty much all over the world and nobody knows ObjectScript really thoroughly and deeply."
"The area where InterSystems IRIS falls a bit short is in the cost and the licensing cost."
"I cannot determine a very positive impact or a beneficial result from InterSystems IRIS, although this observability part is important because we were able to find problems much faster."
"InterSystems IRIS can be improved by addressing the lack of libraries, mainly mathematical ones, where we would save a lot of time on some formulas that we have to build by hand every time we need them."
"There are some ways that the handling of unstructured data could be improved."
"Sometimes the large injestion takes days to load data, and some of our stored procedures take two to three days."
"The scalability could be better. The on-premises solution is always more complicated to scale."
"Teradata is an old data warehouse, and they're not improving in terms of new, innovative features."
"Teradata is somewhat late in adopting cloud technology."
"An additional feature I would you like to see included in the next release, is that it needs to be more cloud-friendly."
"The primary challenge with Teradata lies in its cost structure, encompassing subscription fees, software licenses, and hardware expenses."
"Query language and its functionality are rather limited, compared to Oracle or even SQL Server. However, it is possible to perform any kind of logic in it (though some workarounds may be required)."
 

Pricing and Cost Advice

Information not available
"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."
"​I would advise others to look into migration and setup as a fixed price and incorporate a SaaS option for other Teradata services​."
"The price needs to be more competitive as Hadoop, Redshift, Snowflake, etc are constantly making way into EDW space."
"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."
"​When looking into implementing this product, pricing is the main issue followed by technical expertise​."
"The cost is significantly high."
"Teradata is a very expensive solution."
"Teradata is expensive but gives value for money, especially if you don't want to move your data to the cloud."
