Efficient real-time fraud detection with integrated debugging support
So, I'm not using it currently, but when I was working with my last organization, which was a gaming company, we used Amazon Neptune for real-time fraud detection. We maintained user data, mobile device data, and other information as graph data. These vertices and the connections between them…

Quotes from Members

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

Pros

"Relational databases are never good at identifying patterns in graphs or other similar relationships, whereas Amazon Neptune is."
"The initial setup is actually simple."
"We can define security rules at the database level or the cluster level to grant or deny access to particular users."
"It stores historical data with ease. For example, if you are a healthcare member, then you will have multiple records of visits to the doctors. To store such data in Oracle Database, you have to create many records. You might also have duplication problems because your records are going in again and again, because of which the data warehouse and the maintenance cost will be huge. MongoDB is comparatively lightweight. It is a JSON extract. Once you define a schema and extract it, you can push all the relationships in any way you want. It is easier to define and get different types of transactions into MongoDB. It is also easier to set it up as compared to other solutions. MongoDB is a NoSQL database, which means it is a document DB in which you can store documents that you created in BSON. It is pretty fast in response. It is faster than relational databases because it does not define any primary keys, secondary keys, tertiary keys, and all those kinds of things."
"It's easy to use."
"MongoDB has definitely helped us improve our network monitoring and reporting dashboard, so I would say it has impacted our operations positively overall."
"The geospatial index feature is useful for dealing with latitude and longitude data."
"The solution is user-friendly with a good object retrieval feature."
"The community is great if you have problem."
"Easier to maintain the data with its document-based storage."
 

Cons

"In my scenario, the integration wasn't easy because ................in Java."
"Amazon Neptune could improve by spreading more awareness for others to have an understanding of the solution because the technology is fairly new. The developer community and larger community do not understand it yet."
"There should be better integration with other databases."
"MongoDB could improve by not having so many updates and different versions."
"The free tools, like MongoDB Compass, could be enhanced."
"MongoDB should be more stable, and support should be more efficient."
"At the start, connecting to the database via Compass or through a direct ID was a challenge."
"The performance could be faster."
"There is room for improvement in integrating MongoDB with agentive AI solutions."
"The stability could be better."
 

Pricing and Cost Advice

"Microsoft Azure and Amazon AWS are on par for pricing and Google has been raising its prices."
"MongoDB is an open-source solution."
"I don't know, but I have heard from people who procure it that it is much cheaper than Oracle."
"MongoDB is an open-source product."
"It's open-source."
"I'm using the free version of MongoDB."
"MongoDB is not expensive."
"The pricing is favorable if you opt to install MongoDB on an Amazon EC2 instance as you won't have to pay for the extra Atlas services and can instead manage the scaling yourself. This allows for a cost-effective solution and using MongoDB on a small scale, I have been able to utilize it for free."
"MongoDB's pricing is reasonable."
