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.

Running secure internal banking applications has been reliable and supports fast deployments
I am still working with Oracle products. I am still using Enterprise Manager 14c. I am using Oracle Database, Oracle ExaCC, Oracle EBS, Oracle WebLogic, Oracle Enterprise Manager, and Oracle Linux. I can answer questions about my experience with WebLogic Suite. I use it in my company. I have not used WebLogic's diagnostic tools. I do not utilize its lifecycle management features. I do not have much experience with WebLogic Java EE support, as I just deploy the application and the other team utilizes this server. I am not directly involved in WebLogic. I have been using Oracle Linux myself. The deployment is local, on-premises. I have been working with Enterprise Manager as well. All the components of Oracle I am using are on-premises. I use Oracle 19c database, Oracle ExaCC, Exadata on Cloud at Customer. I have been using Oracle Linux, Enterprise Manager, and databases as well. I have been working with Oracle Database for about 20 years. My experience has been 100% positive with Oracle Database. I have utilized its Real Application Clusters along with Data Guard. I do not use Oracle's Advanced Analytics and machine learning features right now. I have given this review an overall rating of 9 out of 10.

Delivers consistent performance and enables advanced analytics across complex data environments
Teradata stands out as a solid platform for managing and analyzing large volumes of data. Its architecture allows information to be processed efficiently while maintaining stable performance, even in highly demanding environments. One of its most notable strengths is the ability to run complex queries at high speed, which is essential for organizations that require timely and reliable analytics. Teradata offers a well-integrated ecosystem that supports working with different types of data and enables scalability as organizational needs grow. Its focus on advanced analytics, integration with modern business intelligence tools, and the ability to operate both on-premise and in the cloud make it a versatile solution for data warehousing and large-scale processing. Teradata's stability, technological maturity, and the availability of strong documentation and best practices are noteworthy. I consider Teradata to be a tool with great potential for any organization looking to enhance its analytical capabilities, optimize data processing, and move toward more data-driven decision-making. Teradata stands out as a solid platform for managing a large volume of data in different projects. Its architecture allows information to be processed efficiently while maintaining stable performance, even in high-demanding environments. A well-integrated AI ecosystem that supports working with different types of data and enables scalability as organizational needs grow across different kinds of enterprises or organizations. The focus on advanced analytics integration with modern business intelligence tools is particularly valuable. Teradata combines a powerful parallel process and optimizing SQL engine with a highly scalable architecture allowing businesses to execute complex queries and analytics in real-time. It supports multi-cloud, hybrid, and on-premise environments, giving organizations flexibility to choose the setup that best aligns with their strategy. One of the biggest strengths is the ability to unify disparate data sources and support high concurrency, enabling different teams, such as analytics, operations, BI, and data science, to access consistent, trusted data across the enterprise.

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."
"Informix can support huge quantities of data with less memory and less capacity."
"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."
"Every version is faster than the previous."
"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's stability, performance, enhanced functionality, and replication are all great features."
"The initial setup is pretty easy."
"The stability is incredible. I have customers with uptimes of several years."
"Oracle Database is stable, and I'm quite happy with the performance."
"The most valuable features of this solution are the cost optimizer and partition exchanges."
"Oracle Database is easy to use."
"On-prem, Oracle is the number one database technology."
"In comparison to other more simple structure databases, I consider the Oracle Database to be more scalable, as well as easiness to export from an external system."
"Oracle Database is easy to use."
"It has good features for performance tuning."
"It's one of the leading databases on the market."
"The product is reliable."
"Teradata's scalability is one of its best features."
"It is very stable. It's 100% uptime. Speed and resilience are one of the greatest features of this product. In almost twenty years we've never had downtime, except for outages for patches and upgrades. We've never had a system failure in twenty years."
"We had few reports which were taking more than 45 minutes, then with Teradata we received results within minutes, and a few under a minute."
"Teradata has allowed us to provide an online BI solution that no other player was able to do."
"The data processing, clustering, and distributed computing are impressive."
"Teradata has immensely helped our organization to fetch the data at a faster rate, which has saved us quite a lot of time."
"The most valuable feature is the ease of uploading data from multiple sources."
 

Cons

"I really would love to have a QT plugin."
"I really would love to have a QT plugin."
"The technical support services need substantial improvement."
"The solution doesn't include functionality like data anonymization."
"The solution should offer replication. It would be helpful if the solution would allow us to access third-party tools."
"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."
"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 would like to see more security included. I would also like to see more features added and the stability needs improvement."
"We want Oracle to specify the differences between the two versions, the former version and the newer version and how it is linked."
"The setup for Enterprise Manager Grid Control can be a bit easier."
"Our Oracle database is very expensive, so probably the cost is an area that can be improved."
"We use different products for different requirements. We are switching away from Oracle."
"The product could be cheaper."
"It would be useful if I could connect to an expert for one-on-one help."
"It would be useful if I could connect to an expert for one-on-one help."
"Azure Synapse SQL has evolved from a solely dedicated support tool to a data lake. It can store data from multiple systems, not just traditional database management systems. On the other hand, Teradata has limitations in loading flat files or unstructured data directly into its warehouse. In Azure Synapse SQL, we can implement machine learning using Python scripts. Additionally, Azure Synapse SQL offers advanced analytical capabilities compared to Teradata. Teradata is also expensive."
"Teradata's UI could be more user-friendly."
"Teradata's UI could be improved."
"Sometimes the large injestion takes days to load data, and some of our stored procedures take two to three days."
"The solution is stable. However, there are times when we are using large amounts of data and we can see some latency issues."
"The initial setup is complex because there are a lot of factors that come into play, including the amount of software and applications that require access."
"Teradata can improve the way it handles big data and unstructured data."
"GUI of administrative tools is really outdated."
 

Pricing and Cost Advice

"The product has reasonable pricing. We purchase its yearly license."
"For me, it's always too expensive."
"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."
"There is a license required to use Oracle Database."
"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."
"There are no licensing costs because the solution for me is open source."
"I understand that Oracle is very expensive compared to other databases."
"The price is relative. Licensing costs differ based on how often you'll use the product. They also provide discounts based on the bandwidth or the use cases you want to run on it."
"It has an annual subscription. It is an Oracle solution, so it is a bit expensive, but that's fine."
"The licenses could definitely be cheaper."
"We pay for a yearly licensing subscription. Funds permitting, we have plans to increase usage for Oracle Database in the new year."
"The product cost is high for what the client gets. There may be more cost-effective solutions for small and medium-sized organizations."
"The price needs to be more competitive as Hadoop, Redshift, Snowflake, etc are constantly making way into EDW space."
"​I would advise others to look into migration and setup as a fixed price and incorporate a SaaS option for other Teradata services​."
"Teradata is expensive, so it's typically marketed to big customers. However, there have been some changes, and Teradata is now offering more flexible pricing models and equipment leasing. They've added pay-as-you-go and cloud models, so it's changing, but Teradata is generally known as an expensive high-end product."
"Make sure you have the in-house skills to design and support the solution, as relying on external sources is extremely costly and tends to lock you into specific platforms, tools, and paradigms."
"In this day and age, we want to get things done quickly. So, we go to the AWS Marketplace."
"It is still a very expensive solution. While I very much like the pure technological supremacy of the software itself, I believe Teradata as a company needs to become more affordable. They are already losing the market to more flexible or cheaper competitors."
"Teradata is a very expensive solution."
