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…
Laksiri Bala - PeerSpot reviewer
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

"Replication, all levels of replication, query charting, and the MongoDB embedded are the most valuable features of this solution."
"The initial setup is pretty easy."
"The solution's stability, performance, enhanced functionality, and replication are all great features."
"The scalability is very good."
"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 in-house-built applications in .NET and VB6"
"It supports multiple applications and business intelligence tools."
"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."
"Security is the most valuable feature."
"The scalability of the solution is very good. It's able to support large amounts of data."
"The solution is very fast."
"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 application development is very user-friendly."
"We can integrate it with any data sources as well."
"The on-premise version is stable. We have different teams and resources for the server side, for admin, and for development. We can easily take care of all the services and applications."
 

Cons

"The solution really doesn't add new features very often."
"This product could be made easier to use for beginners."
"I really would love to have a QT plugin."
"I experienced poor input/output (IO) performance."
"I would like to see backups from secondary servers."
"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."
"The support team could include local engineers to establish efficient communication. It will help us speed up the escalation process."
"The solution should move to the new way of writing software code with AI that is intelligent and learns."
"We often have to find solutions on our own through the support site, so there's room for improvement in this regard."
"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."
"They should improve the solution's scalability for large databases."
"The product could benefit from enhancements in its graphical user interface."
"Technical support is below our expectations currently. It could be improved."
"The product could be more economical."
"The solution is quite expensive."
 

Pricing and Cost Advice

"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."
"For me, it's always too expensive."
"Database In-Memory is priced a bit higher than its competitors like Microsoft."
"The pricing is pretty good so I rate it an eight out of ten."
"The product is expensive."
"Oracle Database In-Memory is expensive."
"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."
"It's quite costly and it comes with a fixed price."
"The platform's licensing cost needs improvement."
