Has offered a cost-effective option despite frequent technical issues and limited market demand
We find some bugs in IBM Informix. Maybe we are using it more aggressively than others. Every month or every second month, we find some bugs in it, which is not ideal. It should be rare, not this frequent. The good thing is they cover those bugs in the next release within weeks or days on demand. IBM Informix should become hybrid and should include AI features similar to other DBMS systems such as Snowflake, Redshift, and DataBricks. This would help its value rise with the market.

When it comes to how Oracle Database can be improved, for me it is all about training and development in terms of gamification, creating awareness, and spreading the word to aspiring database administrators and database developers. As I have used it in the past and in recent times, many people are trying to get into IT, so the opportunity exists. Oracle has the market opportunity to take this time to spread its offerings and ensure that many aspiring professionals are aware of its services and products. From my perspective, there is not much to add regarding the needed improvements for the interface and the documentation. I give it a nine because I think Oracle sometimes can make things complicated. You have many services, many products, and many tools for different use cases. So it is difficult for someone who is only used to a particular product, such as Oracle Database, to understand all the other products and services that it provides. Probably streamlining it and making it available with categorized use cases for specific job roles would help. If you are a database developer, these are the tools that you need to be familiar with in Oracle's suite of products, and if you are a database administrator, these are the tools. Categorizing them based on the job role or function of people who are accessing these products and providing training capabilities on how to use them and how these products interchange and talk to each other would be very important because that is one of the things I struggled with when I started my journey as an Oracle Database administrator. Having that visibility of all the software products and providing free training and documentation on how you can improve and which products are best suited for integration to your product from Oracle would go a long way to help organizations and professionals. Regarding Oracle Database's AI capabilities, I am very keen on its governance and security. I think more work needs to be done on the security and ensuring that the database for a large number of people is watertight. AI is here to stay; however, governance and more stress testing of the AI capabilities needs to be done to ensure there is no breach of data. I would rate it currently at 6 over 10 and there is room for improvement. As long as there are government policies and Oracle policies that can mitigate any breaches of data and serious security issues, releasing people's records over the internet, there is always room for improvement in that regard.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Overall, this is a great product. It works really well, is very stable, and is very scalable."
"The solution's stability, performance, enhanced functionality, and replication are all great features."
"We don't have any problems with the Informix Database."
"The stability is incredible. I have customers with uptimes of several years."
"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 is quite stable and reliable; we use it mainly due to its general stable nature."
"The initial setup is very simple."
"It supports multiple applications and business intelligence tools."
"At the end of the day, you get what you pay for, and we don't mind paying more for the peace of mind we get from this solution."
"The solution's most valuable aspect is its reliability."
"The solution is stable and has good performance."
"In our experience, Oracle Database is highly stable, which is the best part of it, and it is certainly much more stable than Microsoft SQL Server."
"Oracle is a stable product and we plan to continue implementing it."
"Oracle Database is easily scalable and has so many enterprise benefits."
"The stability has been very good, its performance is excellent, the ease of use has been great, it's an excellent product, and the integration capabilities are very good."
"If you have the money, then you should invest in this product, because you can't compare it with anything else on the market as far as a database is concerned."
 

Cons

"The support team could include local engineers to establish efficient communication. It will help us speed up the escalation process."
"The solution doesn't include functionality like data anonymization."
"It would be helpful to have IBM salespeople know that Informix exists, and sell it. Currently, it is completely ignored by IBM."
"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."
"The solution really doesn't add new features very often. Other solutions are much more actively pushing out upgrades and improvements."
"This solution is in need of more current tools."
"The solution should offer replication. It would be helpful if the solution would allow us to access third-party tools."
"For me, it's always too expensive. The problem is that Informix sometimes competes with free products, so yes, it's very expensive, but when we're talking about licensed products like SQL Server or anything, the midsize pricing could be significantly improved."
"While Oracle has been excellent, they haven't been growing or leaping forward like other vendors."
"One of the most stable databases I have ever seen, but to be honest the support when you have a bug or something will make your life very hard."
"I think that technically, it's nearly a flawless product. But, when it comes to pricing, it's very expensive."
"We believe that the usability could be improved, especially within the data lakehouse. We found content management to be a little bit more simpler within the GUI part."
"The documentation needs improvement because as it is now, providing support is a headache."
"It's not very user-friendly, and it's a little complex. Another issue that I don't like is the licensing complexity."
"The connection can be slow due to the distance from the provider."
"There are a lot of bugs in the Oracle Database, and it would be better if the bugs would be solved more quickly than they are today."
 

Pricing and Cost Advice

"I am not aware of the licensing costs or terms."
"The product has reasonable pricing. We purchase its yearly license."
"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."
"It's expensive. I would say that it is more expensive than other competing products."
"Our licensing costs are between $40,000 and $50,000 per year. Those are the costs that cover maintenance and licensing."
"The price of Oracle Database is quite high compared to other solutions. It has a lot of options, such as security for partitioning and real application clusters. These options are not for free. Once you want to use it, you have to pay extra."
"We mainly use a special license for ERP systems specifically, instead of a general purpose license. This ERP-focused license is very simple. You just have to use Oracle Database with an ERP system and that's it."
"Oracle is also very expensive."
"​The license cost need to be optimized. The licensing cost is very high compared to other RDBMS."
"The price of Oracle Database is too expensive and especially for individual environments. The pricing model is not clear, if I want to run it on a virtual environment, I still need to license the whole physical box."
"It could be cheaper. We pay for the license on a yearly basis."
