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 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.

Pros

"IBM Informix benefits users with high availability and good integration capabilities."
"So far, we do not have a lot of issues. It's pretty problem-free."
"It supports multiple applications and business intelligence tools."
"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."
"Replication, all levels of replication, query charting, and the MongoDB embedded are the most valuable features of this solution."
"Every version is faster than the previous."
"The scalability is very good."
"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."
"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."
"We find the dashboard and the speed of data processing very valuable in Oracle Database In-Memory."
"The scalability is very good."
"The most valuable aspects of this solution are the fast caching and improved performance to the database"
"Security is the most valuable feature."
"We use the tool for real-time data transfer for risk management purposes. In a trading system, conversions happen fast. We use the product to handle fast transactions with low latency."
"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 solution's ROI is excellent."
 

Cons

"I really would love to have a QT plugin."
"The pricing is a bit expensive."
"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."
"The solution lacks some functionality."
"I experienced poor input/output (IO) performance."
"I would like to see backups from secondary servers."
"The solution really doesn't add new features very often."
"There should be more intelligence surrounding discovering data to be able to automatically create indexes."
"It would be good if Oracle could reduce downtime when transferring from non-In-Memory to In-Memory."
"The solution should move to the new way of writing software code with AI that is intelligent and learns."
"I would like Oracle Database In-Memory to include a data replication feature."
"Oracle Database In-Memory could improve by better supporting generative AI challenges, such as hallucination management."
"Oracle should include column store or advanced query optimization so a database can be optimized by enabling analytic queries to run faster."
"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 be more economical."
"The platform’s pricing needs improvement."
 

Pricing and Cost Advice

"The product has reasonable pricing. We purchase its yearly license."
"For me, it's always too expensive."
"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."
"I am not aware of the licensing costs or terms."
"It's quite costly and it comes with a fixed price."
"The product is expensive."
"Oracle Database In-Memory is expensive."
"The solution's pricing is high."
"The pricing is pretty good so I rate it an eight out of ten."
"The platform's licensing cost needs improvement."
"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."
"I rate the pricing a zero out of ten because Database In-Memory is too costly."
