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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Reliable, robust with great features."
"It is highly scalable, and its performance related to database pruning is very good, and 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."
"The solution has many beneficial features, such as security, support, and stability."
"It is a scalable solution."
"The newly added feature of ALSM is one of the top features"
"This solution is scalable, we have an infrastructure that is based on virtual machines so we can add more to grow as we need, and I am very happy about that."
"Technical support is very helpful and better than competitors such as Dell, Lenovo, or HP."
"I like that its true active-active. For example, if there are two instances within a cluster, we can take one of them down and there's no failover or switch over. There's no primary and secondary, it's true active-active. We can take one side down and we can upgrade that with new maintenance or a new version, obviously testing coexistence beforehand, without impacting the business."
"InterSystems IRIS as a database is very efficient, with its best features being its speed and high performance, along with an easy understanding of its data searching functionalities."
"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."
"The best features that InterSystems IRIS offers in my opinion are the speed in querying data, and due to our system, which requires a large query with a large volume of data, InterSystems IRIS stands out for its query speed, making my work easier."
"The best features InterSystems IRIS offers, in my experience, include being a really powerful engine and a really good database."
"The best features InterSystems IRIS offers are its powerful database and speed, which contribute greatly to my work."
"InterSystems IRIS has had a positive impact on my organization by improving performance and data security."
"My final observation is that everyone should use InterSystems IRIS; it is an amazing tool on the market."
"The best features that InterSystems IRIS offers are its capability to function as both a relational and non-relational database, with performance and speed as specific functionalities that serve as differentiators."
 

Cons

"In other countries, different to US or Canada, the support is not straightforward."
"The IBM Db2 Database needs improved support, and there are many difficulties in using it."
"The management of Db2 should be simplified because there are not too many specialists in this area, and the learning curve of Db2 specialists is very long. After the courses, probably it takes one and a half or two years to get to the point when you are using the product properly in the production systems. So, the complexity is very high, and the most important thing is to simplify the management of the product, including self-maintenance. They should simplify the installation, management, and monitoring to simplify the product. It takes too long for a person to be a specialist in this product."
"​Not very solid compared to its competitors' products.​"
"The GUI interface is not particularly friendly for those who do not have experience with the product."
"The vendor should offer a free version"
"We need some time to improve the performance. We have to perform a weekly REORG, or else RUNSTATS for the databases."
"Right now, the setup for AWS/Azure licensing is very confusing and not cost-effective."
"InterSystems IRIS could be improved, particularly the internal interface of the database."
"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."
"The area where InterSystems IRIS falls a bit short is in the cost and the licensing cost."
"InterSystems IRIS can be improved since its studio is very poor."
"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."
"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."
 

Pricing and Cost Advice

"Compared to other databases, Db2 is relatively cheaper."
"I rate the price of the IBM Db2 Database an eight out of ten."
"The solution's hardware and subscription model for support are very expensive."
"We purchase the product's yearly license."
"It is expensive. The price depends on the size of the machine on which you are installing the Db2 and the features you are using. It also depends on the country. IBM has different policies and different options for payment for this product."
"Among Microsoft SQL Server, Oracle, and Db2, Microsoft SQL Server is the cheapest one, and Oracle is the most expensive one. Db2 is in the middle. As compared to SQL Server, its price could go down. It will be good for customers."
"It is expensive when compared to other products."
"I rate the product pricing a nine out of ten."
