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.

Data platform has transformed analytics and now provides seamless storage and insight on user behavior

Microsoft Azure HorizonDB scales perfectly. It automatically scales whenever there is a load on the application. I have configured the deployment files on my projects, and the database is able to handle automatic scaling by itself, so I do not have to put much attention on that aspect. It scales down automatically as well. I monitored the scaling and scaling out one or two times during the initial stage when I was first including this database in my project. After the first and second times, I checked only the logs for automatic scaling and scaling out. I have not encountered any issue on the scaling side, and it provides consistent performance for both scaling and scaling out.

Quotes from Members

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

Pros

"We have moved a lot of our applications off zOS to distributed platforms and IBM UDB DB2 has been extremely critical in our solution to provide for a scale-able, cost-effective and reliable DBMS solution on distributed platform."

"After migrating to DB2, the performance and stability of our Wealth Management system is much better than it was on Microsoft SQL Server."

"The structure is straightforward, consisting of the test file and the logical and physical files. You have one physical file and many logical files related to it."

"The most valuable feature of this solution is the integration with other IBM products."

"The solution helps secure the database."

"The solution's initial setup is straightforward."

"Scales well enough for a relational database."

"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."

More IBM Db2 Database pros

"Using Microsoft Azure HorizonDB provides better scalability and performance in terms of database administration."

"Since we are in the proof of concept phase, we have noticed some early improvements and potential benefits that stand out so far in terms of speed, reliability, and ease of management."

"I appreciate the features that Microsoft Azure HorizonDB provides, particularly the seamless transformation of the database, data collection, and database access along with the analytics features."

"Microsoft Azure HorizonDB has positively impacted my organization by reducing latency issues, improving performance, and providing a good recovery time."

Cons

"The initial setup could be improved."

"In other countries, different to US or Canada, the support is not straightforward."

"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."

"It would be helpful to have a hybrid data storage facility that includes NoSQL technologies."

"Automatic upgrade process (e.g., from v9.7 to v10.5) often fails."

"The usage of Db2 could be simplified, as it is quite complex and requires substantial knowledge of Db2 and zOS."

"IBM's support isn't as strong as it used to be, especially when it comes to providing fixes."

"IBM Db2 Database could improve in the steps it takes for upgrades. It is not an easy process. The process of upgrading the version is lengthy and requires a lot of time. To make it more efficient, I suggest implementing some automation on the solution side. This will greatly reduce the time required for the upgrade."

More IBM Db2 Database cons

"So far, I have not seen any return on investment from Microsoft Azure HorizonDB in terms of cost."

"I want to say that the costing of Microsoft Azure HorizonDB is too high and should be less."

"Regarding needed improvements, I feel that we need more documentation on Microsoft Azure HorizonDB."

"One area I can identify for improvement is query performance during peak traffic situations."

Pricing and Cost Advice

"Clients are required to purchase a license."

"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."

"Licensing fees are on a yearly basis."

"It's very expensive for West African countries like ours."

"It is expensive when compared to other products."

"We normally handle large size businesses and as far as I am aware, the license is negotiable based on the number of users and the quantitative data."

"If I consider the price of IBM Db2 Database, I would say there are cheaper products in the market."

"Compared to Oracle, it is so much cheaper."
