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."
"Replication is a valuable feature and easy to use."
"So far, we do not have a lot of issues. It's pretty problem-free."
"The solution's stability, performance, enhanced functionality, and replication are all great features."
"It supports multiple applications and business intelligence tools."
"The initial setup is pretty easy."
"It supports in-house-built applications in .NET and VB6"
"The scalability is very good."
"It efficiently handles low-code data and supports read-and-write operations for clustering."
"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."
"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."
"The scalability is very good."
"The solution is very fast."
"I find the performance features of Oracle Database In-Memory to be most beneficial."
"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 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."
"I would like to see backups from secondary servers."
"There should be more intelligence surrounding discovering data to be able to automatically create indexes."
"The technical support services need substantial improvement."
"I really would love to have a QT plugin."
"This product could be made easier to use for beginners."
"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."
"Oracle should include column store or advanced query optimization so a database can be optimized by enabling analytic queries to run faster."
"They should improve the solution's scalability for large databases."
"We often have to find solutions on our own through the support site, so there's room for improvement in this regard."
"The solution should move to the new way of writing software code with AI that is intelligent and learns."
"The high cost of the product is an area of concern where improvements are required."
"The solution is quite expensive."
"Oracle Database In-Memory could improve by better supporting generative AI challenges, such as hallucination management."
"It would be good if Oracle could reduce downtime when transferring from non-In-Memory to In-Memory."
 

Pricing and Cost Advice

"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."
"The product has reasonable pricing. We purchase its yearly license."
"The product 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."
"I rate the pricing a zero out of ten because Database In-Memory is too costly."
"Database In-Memory is priced a bit higher than its competitors like Microsoft."
"The platform's licensing cost needs improvement."
"Oracle Database In-Memory is expensive."
"The pricing is pretty good so I rate it an eight out of ten."
"It's quite costly and it comes with a fixed price."
