Supports multiple business intelligence tools, but the technical support services need improvement
IBM Informix is a central database solution across various environments, supporting multiple applications and business intelligence tools The key areas for improvement revolve around understanding the current customer trends and demands, particularly in software and database requirements. The…

Faster processing and improved memory operations have enhanced transaction and analytics efficiency
The valuable features of Oracle Database In-Memory ( /products/oracle-database-in-memory-reviews ) include its capability to bypass disk storage for faster memory operations, which is critical for transactions and analytics. It also offers specific memory areas, like in-memory cache, that act as intermediaries between disk and buffer cache. This feature helps organizations handle real-time memory requirements effectively.

Quotes from Members

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

Pros

"For IoT business cases, having Informix Enterprise Edition work on edge computers, like Raspberry Pi and using Informix replication, makes complex situations simple to build and maintain."
"It supports in-house-built applications in .NET and VB6"
"Replication, all levels of replication, query charting, and the MongoDB embedded are the most valuable features of this solution."
"This solution has made financial reporting possible by allowing financial people the opportunity to set Informix to "Auto Pilot" so that they can attend other duties."
"It supports multiple applications and business intelligence tools."
"Every version is faster than the previous."
"The stability is incredible. I have customers with uptimes of several years."
"So far, we do not have a lot of issues. It's pretty problem-free."
"We can integrate it with any data sources as well."
"The most valuable aspects of this solution are the fast caching and improved performance to the database"
"It accelerates query processing, which in turn speeds up operations and streamlines workflow, and ultimately enhancing productivity."
"Normally, every database server uses hard disks. In-Memory has a feature, apart from their database, which is very good. When we start our server, all your data needs loading memory. We can use that. It's a very good feature. I think they added this feature in 2019. We can mount memory in the partition, create partitions in there, and create table space from that spot to share. It's a really good feature. We use it a lot."
"The scalability is very good."
"The solution is very fast."
"The valuable features of Oracle Database In-Memory include its capability to bypass disk storage for faster memory operations, which is critical for transactions and analytics."
"The most valuable feature is that Database-In-Memory is more consistent and faster than traditional databases as it requires fewer CPUs to process instructions."
 

Cons

"The technical support services need substantial improvement."
"The pricing is a bit expensive."
"It would be helpful to have IBM salespeople know that Informix exists, and sell it. Currently, it is completely ignored by IBM."
"This solution is in need of more current tools."
"In my opinion, the packages could be improved. The version I use doesn't allow for packages. I can do some general procedures, but no packages like in Oracle. So, develop separate modules in SQL language. This would be most beneficial for me."
"Continue extending the SQL language for compatibility with the competition's language, including Stored Procedure Language."
"The support team could include local engineers to establish efficient communication. It will help us speed up the escalation process."
"I really would love to have a QT plugin."
"It would be good if Oracle could reduce downtime when transferring from non-In-Memory to In-Memory."
"Oracle Database In-Memory could improve by better supporting generative AI challenges, such as hallucination management."
"The query optimization and backup features should be added."
"The solution is quite expensive."
"We use some partitions in In-Memory. We have a very large table and a low dose. It is very expensive in data to load all of them into In-Memory. It takes up more memory slots in the server, as well as a lot of RAM. We use last partitions on the table. We always need to create a script and make a schedule that can load a last partition in In-Memory. Oracle doesn't have features to do this automatically. I would like them to allow us to load last partitions, as well as other table partitions, in In-Memory. I think a good feature would do that automatically, letting you see a table, load a large partition, and monitor loading memory. It's quite a good feature."
"The product could benefit from enhancements in its graphical user interface."
"We often have to find solutions on our own through the support site, so there's room for improvement in this regard."
"The product could be more economical."
 

Pricing and Cost Advice

"For me, it's always too expensive."
"The product has reasonable pricing. We purchase its yearly license."
"I am not aware of the licensing costs or terms."
"The free edition can be enough to handle moderate-size implementations, but you may want a pay for edition to benefit from more functionality, such as replication."
"The product is expensive."
"It's quite costly and it comes with a fixed price."
"There is a need to make a yearly payment towards the licensing costs, after which there is any to pay towards the support cost attached to the solution."
"The solution's pricing is high."
"Oracle Database In-Memory is expensive."
"The platform's licensing cost needs improvement."
"The pricing is pretty good so I rate it an eight out of ten."
"Database In-Memory is priced a bit higher than its competitors like Microsoft."
