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

"One of the most valuable features is real-time replication. The version we're using is reliable and easy to deploy."
"The most valuable feature is the flashback standby, which allows us to test without scrapping the database."
"Oracle Data Guard is a free solution. When you apply for Enterprise Manager, it comes for free with the solution."
"If you have a problem with your primary site and can't access your primary database, you can continue working with the database that you have as standby on the other site, by changing its role to primary."
"We chose this solution for the availability of the databases. We can't afford Oracle Grid, this is the best solution if you want something similar that's less expensive."
"The solution can scale as needed."
"With Data Guard, Oracle guarantees zero data loss, providing peace of mind for organizations relying on their data for critical operations."
"The most valuable features are the backup and restore. With this in place along with the clustering, the database is safe from hacking, hardware failure, power failures, and system crashes."
"Teradata's capabilities enhance data management efficiency, support scalability, and contribute to faster query performance."
"​Parallel processing features have helped to easily dump any size of data and retrieve data with great performance."
"The most valuable feature is the ease of running queries."
"I found all parts --loading, transformation, processing & querying work in parallel, and end-to-end-- to be valuable."
"Auto-partitioning and indexing, and resource allocation on the fly are key features."
"The ability to handle machine data parallel processing is the most valuable feature of Teradata."
"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."
"Cuts time to process huge amounts of data with efficient analytical queries."
 

Cons

"For every standby server you have, you must pay a licensing fee, which is the main disadvantage."
"It is a very useful administrative IT tool. It saves on costs."
"One thing that can be improved is the GUI. It would be good to have a very nice GUI to easily configure and administer, providing different presentations to the database administrator. The feature that can be included is the integration with third-party monitoring systems, that is, monitoring systems from other vendors, not only from Oracle."
"We would like to be able to see the date time stamp when you execute DGMGRL commands."
"The implementation is complex for anyone who's jumping into it without any experience. It's all command-line driven implementations. For some, that's a turn-off."
"The deployment cost is expensive."
"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 only difficult part is the cost factor, licensing. Another area of improvement is support."
"I would like to see more integration with many different types of data."
"Teradata needs to pay attention to the cloud-based solution to make sure it runs smoothly."
"Since I was working on the very basic, legacy systems, the memory thing was always a challenge. If Teradata is moving to the cloud, the space constraint or the memory issue that my company generally faces will eventually resolve, in time. What I'd like to see in the next release of Teradata is that it becomes full-fledged on the cloud, apart from better connectivity to various systems. For example, if I have to read or include a Python script, if I write some basic codes, I should be able to read even unstructured data. I know that it's not supported even in Snowflake, but at least semi-structured data support, if that can be a little more enhanced, that would be good."
"The user interface needs to be improved."
"If I want to implement an upgrade, I'd like to see how it will be different. Ideally, Data Lab should help me test production items and also do future things. Future releases should be downloadable and testable in Data Lab."
"GUI of administrative tools is really outdated."
"Sometimes the large injestion takes days to load data, and some of our stored procedures take two to three days."
"The increasing volumes of data demand more and more performance."
 

Pricing and Cost Advice

"This is the best solution if you want something similar that's less expensive than Oracle Grid."
"The cost of the Oracle license will depend on the negotiations with Oracle."
"If you want to have everything automated and done smoothly, you have to add additional licenses."
"​Oracle Data Guard is a feature available only in Oracle Database Enterprise Edition, and is available for extra cost."
"It is not a cheap product, but if you look at the price, features, availability, scalability, and maturity, it is a very good product."
"The pricing is on the higher side."
"The cost is expensive."
"It's a cost-effective solution."
"​When looking into implementing this product, pricing is the main issue followed by technical expertise​."
"The tool costs about 30,000 euros a month, while Azure Synapse SQL only costs 10,000."
"Teradata used to be expensive, but they have been lowering their prices."
"It comes at a notably high cost for what it offers."
"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."
"The price of Teradata is expensive. However, what they deliver they are outstanding. If you're looking for an inexpensive solution to run a database, this isn't your tool. It's the Ferrari of databases for data warehousing."
"The price needs to be more competitive as Hadoop, Redshift, Snowflake, etc are constantly making way into EDW space."
"Teradata is expensive but gives value for money, especially if you don't want to move your data to the cloud."
