Continuous updates improve performance and add valuable features to meet workload demands
Oracle Database ( /products/oracle-database-reviews ) is easy to install, customize, troubleshoot, and maintain. Its data management capabilities include data quality, data integration, data architecture, modeling, and data security, which are very important for data-driven companies. Furthermore, Oracle Database's performance and scalability features meet workload demands, and its continuous updates improve performance and add valuable features.
Azizul Haque - PeerSpot reviewer
It has eliminated all kinds of inconsistencies, and it is reliable, secure, and fast
I don't know whether SQL Server can support large organizations where the database size is more than 100 GB. It might be because of SQL Server, or it might be because of the programming of the software vendor, but a lot of people think that it is a problem with SQL Server. It can't handle a large amount of data or large data size. In terms of its usage, about 90% of our applications are running on the SQL Server database. We have around 1,600 users for our software, and all the applications are connected to the SQL Server database.

Quotes from Members

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

Pros

"It seems to work."
"Compared to other databases, Oracle Database is very simple to manage in terms of the database itself."
"Offers a lot of backup security and is very powerful."
"A very reliable solution."
"As compared to SQL Server, Oracle Database performs better when you have a huge amount of data. We didn't face any problems when we had a huge amount of data. There were also no issues with importing/exporting and migrating the data."
"It is reliable. It's very stable."
"The solution is very easy to use in general."
"The product provides high availability."
"It is the latest technology and pretty powerful in terms of the high availability of the virtual server."
"Technical support is very good."
"It's great that the database engine is always on."
"If we want to expand to other servers and create an extra node, it's expandable."
"The product's initial setup phase was simple."
"SQL Server stands out due to its robust parallel processing capabilities."
"It is easy to use and very stable."
"It is easy to deploy and easy to maintain."
 

Cons

"Oracle needs to improve its cluster technologies. They need to improve in the cluster technology using ARC due to the fact that sometimes people think that they have a redundant server when they are using ARC with the cluster and think that will increase the performance. In reality, if they are using ii with a big workload, sometimes the performance is not increasing, and can sometimes actually impacts it in such a way that there's some degradation in the performance."
"When it comes to Oracle, the only complaint that I have is their support. For business-critical cases, finding support is a little bit difficult because of the timezone difference. They should provide faster support to resolve issues on time."
"The pricing could be improved."
"Sometimes they tell us we can't upgrade the database for now as there's a vulnerability Oracle couldn't find a solution for."
"An area for improvement would be query performance - in some cases, it's really, really hard to make it run faster."
"It could be cheaper and easier to manage. Support could also be better. Performance could be better. Sometimes testing impacts the prediction performance. We have a complex server that serves both prediction and testing. Sometimes testing applies to many other deployments that impact the service provided. It's a problem for our company."
"I would like to see more patches."
"The consumption of memory and the client memory has been increased exorbitantly in the most recent past."
"More things in SQL Server need to be automated."
"There should be more security updates for the product."
"The number of concurrent users is too limited and other databases are better than SQL in this regard."
"It would be nice if there was a feature to search for a specific value across multiple tables. This would save a lot of time for its users."
"The pricing in general could be better."
"One stability issue I encountered was the deadlocking between calls to the same resources (tables, etc.). That was solved by row versioning."
"The solution could offer more integration with other platforms."
"SQL Server could integrate better with other platforms."
 

Pricing and Cost Advice

"Generally, when you buy Oracle Database, and if you're buying it for your own data center on the on-prem side, you have to go by the processor cores and the list price is around $47,500 for the enterprise edition per core."
"We have a yearly license, and it could be cheaper."
"Its price is a little bit high in terms of competitiveness. It is a little bit expensive. For any additional features, there are additional costs."
"We need to pay an annual subscription for the solution, which is moderately priced."
"When you consider the services, Oracle is reasonably priced."
"You have to purchase extra licenses for Oracle Data Guard."
"You buy it initially, and then you pay for yearly support if you need support. If you don't need support, you can also use it without the support."
"The price of the solution is expensive compared to other database solutions. We are on an annual subscription."
"The price of the solution is very expensive. If I went with the cloud version of SQL a license would cost me approximately 11,000 Riyals per month."
"The price could be cheaper."
"​It has the easiest licensing."
"I would rate the tool's pricing a six out of ten. It is not extremely cheap but also it's not the most expensive product."
"It is expensive in terms of licensing costs and pricing. If you want to scale SQL Server, it is very expensive. We probably have to pay extra for technical support. We also have to pay for the license of Windows on which the SQL Server resides, which is an extra cost."
"The licenses are purchased annually."
"The price of SQL Server is great. In my company, SQL Server is part of the Microsoft Suite, we don't have to pay for any additional license costs, it's quite cost-effective for us."
"​We are a Microsoft shop, so we use Active Directory. That integrates well with this product, but we did look at Oracle. We also looked at IBM. This was the best price point for us for what we were getting.​"

As always, it depends: First look is the area: on-premise server (your own hardware) or in the cloud? If you want to use your own server, look at the operating system? In my opinion, SQL Server fits best on Windows; Oracle on Unix/Linux.  Next is your size of data and the application you want to use: rule of thumb: the more data, the more I tend to Oracle; but Oracle is not 'automatically better'! You need an expert to configure the system for optimal use! A simple setup is often not enough! (There are a lot of screws you can turn, but turning the wrong ones is a negative! And more Hardware is not the solution to a slow system). I think the first step is to look at which app creates and consume which data, where in your network is your data needed and then decide the RDBMS. I have worked for years in a mixed environment; we use a large Oracle RDBMS on AIX to store the large amount of data of several production systems; but also some SQL Server RDBMS to distribute data for some evaluations or reports. In the Oracle RDBMS are 30 Years of data of the whole production process; in SQL Servers are consolidated data for reporting. So first make a compilation of your existing data and application and the future requirements; then you can decide; and the result can also be a mixed world!

Your decision should ideally be based on: - The specific needs and existing infrastructure of your organization. - Cost considerations. - Desired features and potential future scaling. - Expertise available within your organization or your hiring intentions. I can provide a comparison based on the characteristics of Microsoft SQL Server's Enterprise Edition and Oracle Database's Enterprise Edition: 1. Licensing and Cost: - SQL Server: Historically, SQL Server has been considered to be more cost-effective than Oracle. Microsoft offers both core-based and CAL (Client Access License) based licensing options. - Oracle: Oracle is often perceived as more expensive, with its licensing based primarily on cores (with considerations for hyper-threading). There are also additional costs for add-on features which might be included in other platforms. 2. Platform Integration: - SQL Server: Tends to have better integration with other Microsoft products like Windows OS, .NET, Azure, etc. - Oracle: Oracle offers a wide range of integrated tools, but the integration might not be as smooth with non-Oracle products. 3. Performance: - Both databases are enterprise-grade and offer high performance, but the actual performance can depend on the specific use-case, database design, hardware, and many other factors. 4. Features: - SQL Server: SQL Server offers features like Always On Availability Groups, Columnstore Indexes, and integration with tools like Power BI. - Oracle: Offers advanced features like Real Application Clusters (RAC), Exadata optimizations, Advanced Compression, Partitioning, etc. Some of these features, however, come with additional licensing costs. 5. Ease of Use: - SQL Server: Often considered more user-friendly, especially for those organizations already embedded in the Microsoft ecosystem. - Oracle: Might have a steeper learning curve, but offers flexibility and depth for those familiar with it. 6. Cloud Integration: - SQL Server: Has tight integration with Azure, Microsoft's cloud solution. - Oracle: Oracle Cloud offers various services tailored to the Oracle Database, and the company has been pushing its cloud services aggressively.
