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.

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."
"Every version is faster than the previous."
"The stability is incredible. I have customers with uptimes of several years."
"Replication, all levels of replication, query charting, and the MongoDB embedded are the most valuable features of this solution."
"So far, we do not have a lot of issues. It's pretty problem-free."
"It supports in-house-built applications in .NET and VB6"
"Replication is a valuable feature and easy to use."
"IBM Informix benefits users with high availability and good integration capabilities."
"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 application development is very user-friendly."
"Oracle Database In-Memory is a suite of features that improves performance for real-time analytics and mixed workloads."
"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."
"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 scalability of the solution is very good. It's able to support large amounts of data."
"I find the performance features of Oracle Database In-Memory to be most beneficial."
"The product offers high scalability."
 

Cons

"It would be helpful to have IBM salespeople know that Informix exists, and sell it. Currently, it is completely ignored by IBM."
"The pricing is a bit expensive."
"This solution is in need of more current tools."
"I experienced poor input/output (IO) performance."
"This product could be made easier to use for beginners."
"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 would like to see backups from secondary servers."
"The product could be more economical."
"The solution is quite expensive."
"Lacks sufficient integration with other tools."
"The high cost of the product is an area of concern where improvements are required."
"The solution should move to the new way of writing software code with AI that is intelligent and learns."
"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."
"I would like Oracle Database In-Memory to include a data replication feature."
"Oracle Database In-Memory appliance-based solutions can be restrictive for some applications, as they may require more flexibility in the database design to be tuned and sized to the customer's needs."
 

Pricing and Cost Advice

"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."
"For me, it's always too expensive."
"The product has reasonable pricing. We purchase its yearly license."
"Oracle Database In-Memory is expensive."
"The pricing is pretty good so I rate it an eight out of ten."
"The solution's pricing is high."
"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."
