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.

Long term database experience has supported OLTP workloads and delivers reliable cross platform migrations
SAP is not putting money into modernizing SAP Adaptive Server Enterprise. One of the things I discovered on the last project I was on was that they did not incorporate the Intel new instruction set in SAP Adaptive Server Enterprise. Intel has augmented its instruction set referred to as new instructions. They did that to make conversion easier. When you migrate SAP Adaptive Server Enterprise cross-platform, you go through a process where it converts the character set. If you are going from AIX to Linux or from Solaris to Linux, Linux is referred to as Little Endian, while AIX or Solaris are considered Big Endian. This is determined by how the product stores data. The word size of these processors is 32 bits long. If you start numbering from the little end, it is referred to as Little Endian. If you start numbering from the big end, it is called Big Endian. To migrate a SAP Adaptive Server Enterprise database from a Big Endian setup like AIX or Solaris to migrate to a Big Endian setup on an Intel, the operating system determines whether it is Little Endian or Big Endian. When you migrate from Big Endian to Little Endian, the database has to go through a character set conversion, and some of these databases are quite large with gigabytes and gigabytes of data. They have to do a character set conversion to the existing database before they do anything else. The worst part is that you have to rebuild all the indexes when you do that. When you switch endianness of the database, you have to rebuild all the indexes. It will automatically do that for system tables, but for actual user databases, you have to rebuild all your indexes, and it takes a long time. SAP Adaptive Server Enterprise is a relational database and is the predecessor of Microsoft SQL Server. All that functionality that Microsoft SQL Server had came from essentially SAP Adaptive Server Enterprise. The problem with SAP Adaptive Server Enterprise these days is it is not expanding its place in the marketplace or expanding its position in the marketplace. A lot of companies have migrated away from SAP Adaptive Server Enterprise. It works fairly well, but the problem is SAP Adaptive Server Enterprise was architected to be an OLTP engine and is now doing things for larger databases that were not in its original intended purpose. The endianness of the RDBMS is a major impediment to continuing to use SAP Adaptive Server Enterprise. You have a multi-gigabyte database, and it will go through a conversion process in a single-threaded fashion, and then you have to rebuild the indexes. Rebuilding the indexes is lengthy and time-consuming. The part of the conversion process that is concerned with conversion of the character set is single-threaded. You may have eight cores on your machine or virtual machine and only one can be used in the conversion process. There is another problem with the whole thing in that it will sometimes not operate properly. Under certain workloads, SAP Adaptive Server Enterprise will become overwhelmed. When you convert it, it does not operate properly in all circumstances. The root cause of that is that SAP in its desire to save money and desire to orphan the product has not recompiled or redeveloped the product to take advantage of the Intel new instruction set. Other relational databases such as Oracle and Microsoft SQL Server have the same issue to deal with, but with those platforms, they are taking advantage of the new instruction set. There are some additional Intel instruction sets or instructions in their Intel instruction set. With SAP Adaptive Server Enterprise, they did not bother to incorporate support for the new instruction set instructions. In certain circumstances, the database does not operate properly. It is unable to do what it needs to do. If you do your research and go on the internet and see what happens with Oracle or Microsoft SQL Server, what comes back is that it takes 4% longer to perform a lot of the instructions. When you are using the new instruction set, it adds 4% to the runtime of the database.

Quotes from Members

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

Pros

"The solution is quite stable and reliable; we use it mainly due to its general stable nature."
"Replication is a valuable feature and easy to use."
"It supports in-house-built applications in .NET and VB6"
"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."
"The scalability is very good."
"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."
"This solution has made financial reporting possible by allowing financial people the opportunity to set Informix to "Auto Pilot" so that they can attend other duties."
"The solution's stability, performance, enhanced functionality, and replication are all great features."
"This is a wonderful database that is, in my opinion, underrated. Users are able to get the most out of my experience by taking advantage of its centralized environment."
"During the last 20 years, I have never had a stability problem with this product."
"They provide easy integration with other systems."
"Sufficient, robust, power DB."
"It's user-friendly, especially in the logistics field."
"The actual interface is good."
"It's pretty good at handling a large number of transactions, which is critical for a banking client."
"Provides very good integration."
 

Cons

"The support team could include local engineers to establish efficient communication. It will help us speed up the escalation process."
"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 really would love to have a QT plugin."
"The solution really doesn't add new features very often. Other solutions are much more actively pushing out upgrades and improvements."
"Every month or every second month, we find some bugs in it, which is not ideal."
"There should be more intelligence surrounding discovering data to be able to automatically create indexes."
"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."
"Informix is very sturdy, but the problem for us is the marketing action around Informix."
"SAP should refine its debugging method, and the process needs to be a little faster. It should use more Pragmas and fewer pseudocomments. I would like if SAP added more features based on advanced technologies, like artificial intelligence and voice control. The modularization and if-else techniques could also incorporate the latest technology to code and solve complex problems. The SAP Editor should be more elaborative, and it should allow many more types of statements for all uses."
"They turned a functional product into something where you have to go through a difficult process to do the conversion."
"I think that the solution needs to be positioned better within the market as it appears as though the Adaptive Server is being left out of the SAP scope."
"There is lack of good support in Mexico - I would prefer Oracle or IBM over SAP in terms of support."
"Better promotion. Sybase seems little known."
"User interface could be more user friendly."
"I'd like to see a more friendly user interface."
"Cluster features: The Cluster Edition didn't get the same level of reliability as the Enterprise Edition did."
 

Pricing and Cost Advice

"I am not aware of the licensing costs or terms."
"For me, it's always too expensive."
"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."
"The product has reasonable pricing. We purchase its yearly license."
"Price-wise, the product is worth it since one needs very less infrastructure to use it."
"The licensing cost for ASE is pretty low."
"I rate SAP Adaptive Server Enterprise's pricing a six out of ten."
