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

"For our clients who have a large scale enterprise, we suggest DB2 and mid-scale enterprise customers we suggest SQL Server or others."
"The solution can scale."
"The most valuable feature of the solution is its compatibility with IBM Power Systems."
"I would say that IBM DB2 is one of the topmost Database products."
"The valuable features include access path optimization, excellent performance, a robust locking mechanism, parallelism, and effective buffering in memory."
"The solution is stable."
"In summary, this is a good solution and one that I recommend."
"It's very secure."
"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."
"My final observation is that everyone should use InterSystems IRIS; it is an amazing tool on the market."
"InterSystems IRIS has positively impacted my organization by reducing the speed at which we are able to collect data and process it and transmit it and has enabled us to conform to certain regulatory requirements, specifically a CMS 9115 requirement, by making sure that the claims data is available."
"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 are its powerful database and speed, which contribute greatly to my work."
"The best features InterSystems IRIS offers, in my experience, include being a really powerful engine and a really good database."
"InterSystems IRIS has had a positive impact on my organization by improving performance and data security."
"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."
 

Cons

"The IBM Db2 Database needs improved support, and there are many difficulties in using it."
"We just want a bit more integration with Linux. That said, we are already seeing Linux more readily available on the mainframe environment."
"There could be more user-friendly tools with features such as drag-and-drop functionality, visual basics, and low-code capabilities."
"The tool is not easy to use. It needs to improve scale computing so that the tool can be scaled vertically. The product needs to enhance pre-engine optimization and it needs to be more efficient in completing queries. The documentation should be updated to include different scenarios of deployment."
"Automatic upgrade process (e.g., from v9.7 to v10.5) often fails."
"The diagnostic log (db2diag.log file) could be a little bit more user-friendly."
"The capabilities of this solution could improve."
"IBM Db2 Database could improve with better security."
"InterSystems IRIS can be improved since its studio is very poor."
"They have very outdated interfaces, and their source control is completely clunky and outdated."
"The area where InterSystems IRIS falls a bit short is in the cost and the licensing cost."
"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."
"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."
"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."
 

Pricing and Cost Advice

"It is expensive."
"I rate the price of the IBM Db2 Database an eight out of ten."
"It's very expensive for West African countries like ours."
"Compared to other databases, Db2 is relatively cheaper."
"We purchase the product's yearly license."
"It's very expensive."
"It is expensive when compared to other products."
"I would rate the pricing a five out of ten. It's not super expensive, but also not cheap."
