reviewer2892648 - PeerSpot reviewer
Developer/Database Administrator at a transportation company with 201-500 employees
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.
Shakti Gupta - PeerSpot reviewer
SQL server database administrator at a tech vendor with 10,001+ employees
Hybrid data platform has strengthened performance, security, and incident response for production
SQL Server is very mature, but I see areas for improvement, especially in performance tuning, troubleshooting, and automation. Although tools such as Query Store and dynamic management views are powerful, some troubleshooting tasks still require senior SQL Server database administrator expertise. It would be valuable to have more intelligent, built-in recommendations for root cause analysis, indexing, blocking, and query optimization. I would also like to see simplified and consistent management across on-premises SQL Server and Azure SQL services, as managing hybrid environments sometimes requires different tools and approaches. Finally, improved patching, updates, monitoring, and cost and license transparency could make SQL Server easier to manage at the enterprise scale. One area I would improve in SQL Server is its documentation and troubleshooting guidance. SQL Server documentation is comprehensive, but for complex production issues, I would like to see more real-world troubleshooting examples, especially for scenarios such as Always On synchronization issues, blocking and deadlocks, performance degradation, and upgrade features.

Cons

"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."
"InterSystems IRIS can be improved since its studio is very poor."
"InterSystems IRIS could be improved, particularly the internal interface of the database."
"The area where InterSystems IRIS falls a bit short is in the cost and the licensing cost."

Pricing and Cost Advice

Information not available
"Pricing is a bit on the higher side."
"As compared to Oracle Database, SQL Server is less expensive. For mid-sized organizations, SQL Server is completely all right, but people say it can't support large organizations with more than 2,000 users."
"The areas that need improvement are with regards to the commercial aspect of the solution, the licensing cost could be reduced in order to help customers to adopt it."
"The enterprise-level license agreement is very complicated."
"It requires the purchase of a license."
"The price for the Standard Edition is approximately $3,000 USD per core. Once you include technical support, SQL Server is cheaper than PostgreSQL and MySQL."
"The cost is high and because it's an expensive product, we are in the process of moving towards open-source solutions."
"There is a license required for this solution."
