A fast and affordable solution that is scalable and has a nice dashboard
The product enables the users to query results faster. It maintains all the versions of the changes done on a specific node. A traditional blockchain would take time, but Amazon QLDB is a bit faster. We have to do many operations in blockchain to read data, but QLDB comes with an easy syntax. The product provides a nice dashboard to view all the information.

Quotes from Members

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

Pros

"The product enables the users to query results faster."
"Sharding is an excellent feature of MongoDB."
"The most valuable feature of MongoDB is the NoSQL database. In a SQL database, we need to join data together with a unique ID amongst other things, but in MongoDB, it's not required. We can directly receive all the information. The performance is very good. Additionally, they have frequent updates."
"I like the schemaless architecture that it follows. I also like the sharding that it provides."
"MongoDB is scalable and stable. The initial setup is very easy, and deployment and maintenance can be done by one person."
"MongoDB's approach to handling data in documents rather than traditional tables has been particularly beneficial."
"I value the API integrations."
"I find the integration with other tools very easy."
"It can handle a lot of files quickly."
 

Cons

"The product should enable users to import data from various databases."
"Some of the solution's transaction capabilities can be improved."
"More stable indexes would be helpful in a future release. That's been an issue for some time. I don't know if it's been fixed now but we transitioned to it because we needed a search index to be able to search for things and if that goes or starts disappearing, we have to move away from that solution. I don't know if they fixed it, last time I had this issue was three years ago so they might have solved it."
"Simplifying the aggregation framework would be an improvement."
"The analytics needs improvement."
"The stability could be better."
"The user interface is not as friendly as Oracle, which is something that can be improved."
"MongoDB should improve its data loading part."
"I don't see a lot of areas that need improvement."
 

Pricing and Cost Advice

"The product is not expensive."
"MongoDB's pricing is reasonable."
"It is rather expensive."
"I don't know, but I have heard from people who procure it that it is much cheaper than Oracle."
"I'm using the free version of MongoDB."
"MongoDB has a free version. You can also buy the enterprise edition, which is cheaper than Oracle."
"The pricing is normal. Price-wise, the product is not too much expensive."
"I believe that the licensing fees are paid on a yearly basis."
"MongoDB is not expensive."
