Database has secured high-volume transactions and supports fast, compliant workflow processing
Sterling B2B Integrator is a highly transactional-oriented application, which can be described as an OLTP application. Any data that flows through the application is stored in the database for each step that it performs. IBM Db2 Database helps the application work much faster from an OLTP perspective. IBM Db2 Database is SSL enabled, which means that from the security point of view, any access to the database is through SSL. Additionally, all compliance-related aspects have been taken care of from the database point of view, including database encryption and security-related features. It is highly scalable, and its performance related to database pruning is very good. It can be scaled vertically or horizontally so that data insertions and data access are much faster and more secure compared to how Oracle or other databases work.

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.

"InterSystems IRIS can be improved since its studio is very poor."
"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."
