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

"IBM Informix benefits users with high availability and good integration capabilities."
"The initial setup is pretty easy."
"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."
"Not looking at Informix would really mean a shot in your own leg before walking a long distance."
"The scalability is very good."
"Informix can support huge quantities of data with less memory and less capacity."
"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."
"My advice is to take it; you will never regret it."
"Rewriting legacy procedural modules to SQL with analytic functions has on several occasions turned multi-hour jobs into few-minute jobs."
"The most valuable feature of Oracle Database is all the functionalities. When we write a code we sometimes have to create an explicit functionality to process the data that we want. At times we find that there is already existing functionality in data created by Oracle itself, it is helpful."
"Oracle Big Data Discovery's ability to let business users explore that large volume of data gives them a significant advantage."
"I feel this is one of the best features in 12c, multi-tenancy."
"Our internal data management system runs on Oracle Database."
"The most valuable features of Oracle Database are that it's very powerful, very reliable, and very fast."
"Oracle Database is stable and reliable."
"If you want to have a high-performing, stable, secure, and scalable system, you will choose Oracle Database."
 

Cons

"The support team could include local engineers to establish efficient communication. It will help us speed up the escalation process."
"The solution lacks some functionality."
"The solution should offer replication. It would be helpful if the solution would allow us to access third-party tools."
"This product could be made easier to use for beginners."
"There should be more intelligence surrounding discovering data to be able to automatically create indexes."
"It would be helpful to have IBM salespeople know that Informix exists, and sell it. Currently, it is completely ignored by IBM."
"I experienced poor input/output (IO) performance."
"The product needs a lot more marketing involvement from IBM."
"The only major thing that we see right now is the downtime."
"The tool is costly, and migration is hard. We need tools like Database Migration Assistant for Oracle to migrate data between databases. Sometimes, older versions of Oracle are no longer supported, making the transition even more difficult."
"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."
"Our customers sometimes complain about the price of the license, as it is very high for them."
"It's not very user-friendly, and it's a little complex. Another issue that I don't like is the licensing complexity."
"Even if you have backup discs and never use Data Guard, you still have to pay for a license for it."
"The solution is not for everyday use. It is not easy to use and maintain."
"Considering the current threats in the industry, my company has to put in efforts to update the tool, or we have to work on some more things so that we can have a secure environment."
 

Pricing and Cost Advice

"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 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."
"Its cost is astronomical. They charge by the size of the server rather than what you're actually using. It is just a terrible business model. It has got a ton of features that are great, but you have to pay for them, and we don't want to spend a lot of money. If you use any of their additional products, you have to pay for those. Almost everything extra is at an additional charge. We also use RAC, and there is an additional charge for that."
"The solution is expensive."
"It's expensive. I would say that it is more expensive than other competing products."
"Pricing for this solution is on the high side. Their licensing policy also needs to be improved."
"The price of Oracle Database is high and could be reduced."
"I rate Oracle Database's pricing a four out of ten."
"We have been paying for an annual enterprise license Oracle Database."
"It would be a benefit if there were different pricing levels to help different size businesses."
