Continuous updates improve performance and add valuable features to meet workload demands
Oracle Database ( /products/oracle-database-reviews ) is easy to install, customize, troubleshoot, and maintain. Its data management capabilities include data quality, data integration, data architecture, modeling, and data security, which are very important for data-driven companies. Furthermore, Oracle Database's performance and scalability features meet workload demands, and its continuous updates improve performance and add valuable features.

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."
"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."
"It supports in-house-built applications in .NET and VB6"
"It supports multiple applications and business intelligence tools."
"So far, we do not have a lot of issues. It's pretty problem-free."
"The initial setup is pretty easy."
"The scalability is very good."
"A very reliable solution."
"The thing that probably stands out the most about Oracle Database is reliability. I have been working with Oracle Databases for over 25 years, and I have never lost any data due to a machine going down or any events that were not stupid human tricks. I've never lost anybody's data using Oracle. It gets the job done and doesn't fail."
"High availability using real application clusters."
"In general, Oracle is quite good. It's a large database that houses many applications."
"There is a lot of functionality in Oracle Database. The reports and the GUI are good."
"It has automatic memory management capability and large file capability."
"The best features of Oracle Database Server are the security, high availability, and the Disaster Recovery solutions with the Data Guard. Specifically, on Autonomous Databases, the most valuable features are the automatic scaling and CPU scaling depending on the database workload. Today, the workload is normal and then suddenly the workload gets a spike."
"The most valuable feature of Oracle Database is its stability - one can trust that the database is always working."
 

Cons

"It would be helpful to have IBM salespeople know that Informix exists, and sell it. Currently, it is completely ignored by IBM."
"The technical support services need substantial improvement."
"Continue extending the SQL language for compatibility with the competition's language, including Stored Procedure Language."
"The pricing is a bit expensive."
"The support team could include local engineers to establish efficient communication. It will help us speed up the escalation process."
"This solution is in need of more current tools."
"There should be more intelligence surrounding discovering data to be able to automatically create indexes."
"I would like to see backups from secondary servers."
"Oracle's technical support is not very effective. Opening support tickets does not yield satisfactory results, whether dealing with Oracle directly or their regional partners."
"The main thing we find could use improvement is the licensing costs. It is quite expensive relative to other database vendors. Cost always comes up as an issue for us as we consider upgrade paths. It's not as easy as we would like it to be."
"Oracle Database could improve by providing access and integration with containers."
"There are good dashboards and other features, but it was previously included in licensing. They are now charging for each and every feature. It was previously bundled."
"We'd like for its price to be a bit lower, both for licensing and support. As it is a top-of-the-line product, it's a bit expensive."
"The cost needs to be reduced because right now, all of our customers are asking us about how they can migrate to any open-source database."
"Oracle Database has improved how we do our administrative backups. The solution has a smaller footprint than 11g, it's more efficient on the resources for the users. It has a smoother user experience with the ERP and fewer field transactions."
"Oracle is not easy to integrate with other systems, which is something that should be improved."
 

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."
"Be prepared to pay for consulting services, and do not underestimate the time required to find and hire good quality database administrators."
"We need to pay an annual subscription for the solution, which is moderately priced."
"It's expensive. I would say that it is more expensive than other competing products."
"We have a yearly license, and it could be cheaper."
"They are pricing themselves out of the market."
"It is quite expensive."
"The tool is expensive. Compared to its stability and eligibility, the tool is expensive, but if I consider the tool's ROI to be better, the tool is affordable with its set of features."
"We have bought a license, and it was a one-time cost."
