Offers near-real-time replication for data consistency and continuously introducing new features through upgrades
There are various advantages. First of all, easy to deploy. The only difficult part is the cost factor, licensing. In other ways, the implementation is very, very important. Like, we have not encountered any major challenges with replication. We were able to achieve near-real-time replication. Also, with the switchover failover, we were not getting any technical issues. It's a pretty stable product. Once you configure it, it goes through the rollback, and then Data Guard introduces this snapshot thing. So once the restoration happens, we can go back to the original thing, and we make that a standard. It's a pretty decent and key function for Oracle. So, enterprise organizations go for Oracle only for features like these.

Quotes from Members

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

Pros

"Oracle Data Guard is a free solution. When you apply for Enterprise Manager, it comes for free with the solution."
"Technical support is very good. If at any time we write a ticket, we get the appropriate answer on time."
"Data Guard also improved because customers with an active Data Guard license want to reduce the I/O in a production environment. Some application complaints to it for Oracle reporting purposes. It has a production environment that needs to be enhanced."
"Backup and application continuity are most valuable."
"With Data Guard, Oracle guarantees zero data loss, providing peace of mind for organizations relying on their data for critical operations."
"It's a very good solution if you want to protect your data across two data centers, or you have a middle man or many administrators who use these solutions for protecting their data. It's very reliable compared to other solutions that are most often not storage-based."
"The most valuable feature is the application or promotional code used in the production protocol to transfer data to the secondary database, situated on the DR site."
"The most valuable feature is the flashback standby, which allows us to test without scrapping the database."
"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."
"The product is reliable."
"A conventional and easily defined way to build a data warehouse or a layer of data marts."
"The most valuable feature is the ease of uploading data from multiple sources."
"Teradata's capabilities enhance data management efficiency, support scalability, and contribute to faster query performance."
"The initial setup was straightforward."
"It's very, very fast"
"I found all parts --loading, transformation, processing & querying work in parallel, and end-to-end-- to be valuable."
 

Cons

"The deployment cost is expensive."
"The only difficult part is the cost factor, licensing. Another area of improvement is support."
"The predominant issue lies in the communication link between the secondary and primary databases."
"The product could improve its pricing."
"For Italian medium-sized companies, the main challenge lies in the cost associated with licenses."
"They may need to include the monitoring and the alerting part in Data Guard."
"I think it would be great to have a graphical interface assistant (like DBCA, ASMCA, NETCA, etc.) for initial configuration, monitoring, configuring Oracle Data Guard Broker and all the Data Guard Broker commands, without needing Oracle Enterprise Manager Cloud Control installed."
"When the data replicates into the standby database there is a possibility of having a microsecond amount of data loss. The data loss occurs when there is a network disconnection between the primary and secondary standby database located in the data centers or if there is a crash in the primary database."
"The cloud is the new challenge and the new opportunity."
"There is some improvement required on OLTP level and some analytical function is missing."
"I would like to see more integration with many different types of data."
"Teradata can improve the way it handles big data and unstructured data."
"Teradata's pricing is quite high compared to Redshift, Synapse, or GCP alternatives."
"Data ingestion is done via external utilities and not by the query language itself. It would be more convenient to have that functionality within its SQL dialect."
"Teradata's UI could be more user-friendly."
"Needs compatibility with more Big Data platforms."
 

Pricing and Cost Advice

"The licensing cost is significantly high."
"​Oracle Data Guard is a feature available only in Oracle Database Enterprise Edition, and is available for extra cost."
"This is the best solution if you want something similar that's less expensive than Oracle Grid."
"If you want to have everything automated and done smoothly, you have to add additional licenses."
"The cost is expensive."
"The pricing is on the higher side."
"It is not a cheap product, but if you look at the price, features, availability, scalability, and maturity, it is a very good product."
"It's a cost-effective solution."
"Users have to pay a yearly licensing fee for Teradata IntelliFlex, which is very expensive."
"Teradata is expensive but gives value for money, especially if you don't want to move your data to the cloud."
"It comes at a notably high cost for what it offers."
"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 not cheap, but you get what you pay for."
"In the past, it turned out that other solutions, in order to provide the full range of abilities that the Teradata platform provides plus the migration costs, would end up costing more than Teradata does."
"The solution requires a license."
"The product cost is high for what the client gets. There may be more cost-effective solutions for small and medium-sized organizations."
