Enhancing analytics with seamless data dumping and reliable support
Our primary use case is data storage and analytics The organization has decided to purchase a full stack solution from IBM due to positive responses, which helped them upgrade from the previous version. The data dumping into the raw zone and the feature of BigQuery is quite attractive. There…

Analytics and data security needs are met but optimization requires improvement

Quotes from Members

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

Pros

"The way that it scales will help a lot of customers that are stuck with Netezza boxes that can't grow any larger.​"
"One of the most amazing features of dashDB is how it uses compression to get results in lighting speed."
"It is stable when there is support from IBM."
"Ease of migration from Netezza DB; IBM ported over all Netezza's functionality and made the warehouse DB/dashDB the best of breed of the two."
"Since my company is an IBM partner, it has enabled us to offer cloud data warehouse solutions on a 100% IBM stack."
"I like that the dashDB solution is built on DB2 technology, which means that you can use all the features of a DB2 database while outsourcing all the hardware and software maintenance."
"The performance is okay as long as the volume of queries is not too high."
"It will be MPP, so performance should improve."
"I loved the simplicity of loading the data and simply relying on the self-tuning capabilities of ADW."
"I like the fact that the solution is self-patching, that it's running machine-learning generally across its logs all the time in order to identify any issues and to self-repair."
"It provides Transparent Data Encryption (TDE) capabilities by default to address data security issues."
"The product is easy to use."
"The performance and scalability are awesome."
"The autonomous database provides several benefits and unmatched performance."
"It is an extremely scalable solution since you can dynamically change the resources as some other cloud solutions."
"It is a stable and scalable solution."
 

Cons

"Db2 is not a solution that I recommend. We have a lot of experience and we are not satisfied with the product or the support that we received."
"Tech support for dashDB is awful. We usually have tickets open for three to four weeks."
"I would like to see improvements in backup and authentication. It needs the ability to increase the number of retained backups to more than 2 days."
"The support channels need to improve."
"There are some limitations in adding data files to table spaces, and improvements are needed for regional support."
"I would rate the level of dashDB support 3.5/5. While they are very knowledgeable in many areas, you can still struggle to get the correct resolution."
"Ultimately, the product itself has challenges and we are not currently satisfied with the support, either."
"With dashDB, scalability and uptime need more improvement."
"There is a need for more storage to be allocated, but over a period of time, it becomes impossible to reduce it after using it."
"I would like to see Application Express and Oracle R Enterprise fully supported, and I would like to see Oracle Data Mining supported as a front end."
"One of the major problem is creating custom tablespace. The ADB serverless option doesn't support custom tablespace creation, which could cause issues during on-premise database migration that requires specifically named tablespace. There should be an option to create customized tablespace."
"A lot of the tools that were previously there have now been taken away."
"My main suggestion for Oracle is the configuration and key values that come for JSON files. When we create a table, especially if you see in our RedShift or some other stuff, if I create a table on top of a JSON file with multiple array columns or superset columns, those column values create some difficulty in Oracle."
"The solution could be improved by allowing for migration tools from other cloud services, including migration from Amazon Redshift, RDS, and Aurora."
"Ease of connectivity could be improved."
"Oracle should increase visibility options because what's available now is limited."
 

Pricing and Cost Advice

"If your going to go with warehouse DB/dashDB, use the cloud or Sailfish version."
"The price depends on the configuration we choose."
"We pay approximately $70,000 per month. The cost includes maintenance and support."
"You pay as you go, and you don't pay for services that you don't use."
"In terms of architecture and pricing structure, I feel it is a little bit costly compared to Azure. It's fine compared to RedShift, but compared to Azure, it's a bit pricey when you calculate for one TB storage plus around five hours of reporting with the frequency of 1TB data. The cost adds up, making Oracle a bit expensive."
"Oracle Autonomous Data Warehouse's pricing is fair and reasonable compared to the other cloud vendors."
"The licensing cost of the product can vary since you can integrate it very easily with other products or other cloud products...You pay as you use it, so it is not yearly or monthly payments to be made toward Oracle."
"The cost is perfect with Oracle Universal credit."
"The solution is expensive."
