Nasir Niamat - PeerSpot reviewer
DB Consultant at i2c
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.
Srini-Dhanaraj - PeerSpot reviewer
Founder & CEO at imfine.club
The database always has structured data, like rows, columns, and bases
LocalDB is an excellent solution for learners, beginners, and projects of negligible size; it is very good. Any startup can use a local database to start. Once they grow beyond its limits, they can migrate to a MS SQL server that's also available on-premises. I rate it ten out of ten.

Quotes from Members

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

Pros

"It is very easy to install IBM Informix, very easy to scale, and support is quite better."
"Every version is faster than the previous."
"The stability is incredible. I have customers with uptimes of several years."
"The initial setup is pretty easy."
"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."
"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, all levels of replication, query charting, and the MongoDB embedded are the most valuable features of this solution."
"Replication is a valuable feature and easy to use."
"This tool help us build apps quicker and faster."
"The initial setup is very straightforward. The guidelines are very easy to follow. Maintenance is very easy and requires very little manpower."
"The solution is fast."
"The memory footprint is the smallest in its category of products, and I think Microsoft did a very good job squeezing as many features as possible in such a tiny executable."
"The initial setup was simple."
"The most valuable feature of LocalDB is the connection between the application and DB."
"The solution has powerful reporting features that are very valuable."
"LocalDB is an excellent solution for learners, beginners, and projects of negligible size; it is very good."
 

Cons

"The solution doesn't include functionality like data anonymization."
"The technical support services need substantial improvement."
"Every month or every second month, we find some bugs in it, which is not ideal."
"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."
"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."
"This product could be made easier to use for beginners."
"This solution is in need of more current tools."
"The ALM features can be improved, but the database by itself is reliable."
"The storage limit is about 10GB, so for medium to big databases it is not applicable."
"The solution needs to create a management tool. Right now, the solution has tools for creating a local installation, but it's too simplistic. We need something that's a bit more complex so that we can extend the tools with our scripts."
"The initial setup is complex and requires a skilled person."
"It is only for a small amount of data. Local DB is made for the purpose of small-volume optics."
"The internal connection features of LocalDB could improve."
 

Pricing and Cost Advice

"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."
"I am not aware of the licensing costs or terms."
"The licensing cost is too high for LocalDB."
"The fees are fair."
