Supports multiple business intelligence tools, but the technical support services need improvement

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

"The most valuable feature is concurrency and locking because my customers usually use databases in OLTP mode. So, for a large number of competitive users. Other features that are well valued are quick large-scale data types. It is better than Oracle."
"The solution's stability, performance, enhanced functionality, and replication are all great features."
"The initial setup is pretty easy."
"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."
"Every version is faster than the previous."
"The scalability is very good."
"It supports in-house-built applications in .NET and VB6"
"The application development is very user-friendly."
"I find the performance features of Oracle Database In-Memory to be most beneficial."
"The product offers high scalability."
"The scalability is very good."
"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 most valuable feature is that Database-In-Memory is more consistent and faster than traditional databases as it requires fewer CPUs to process instructions."
"It efficiently handles low-code data and supports read-and-write operations for clustering."
"We can integrate it with any data sources as well."
 

Cons

"This solution is in need of more current tools."
"I really would love to have a QT plugin."
"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."
"I would like to see backups from secondary servers."
"Continue extending the SQL language for compatibility with the competition's language, including Stored Procedure Language."
"The solution really doesn't add new features very often."
"The technical support services need substantial improvement."
"The pricing is a bit expensive."
"They should lower the price. My customers think that it's too expensive."
"They should improve the solution's scalability for large databases."
"The platform’s pricing needs improvement."
"Oracle should include column store or advanced query optimization so a database can be optimized by enabling analytic queries to run faster."
"The pricing could be improved. It would ideal if it was more reasonable."
"I would like Oracle Database In-Memory to include a data replication feature."
"The solution is quite expensive."
"The high cost of the product is an area of concern where improvements are required."
 

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."
"For me, it's always too expensive."
"I am not aware of the licensing costs or terms."
"The product has reasonable pricing. We purchase its yearly license."
"The product is expensive."
"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."
"Database In-Memory is priced a bit higher than its competitors like Microsoft."
"It's quite costly and it comes with a fixed price."
"I rate the pricing a zero out of ten because Database In-Memory is too costly."
"The solution's pricing is high."
