Lightweight with good flexibility and very fast performance for searching data
I used the solution in the production level to search data and create education-based tutorials for a project. We had 30 managers, senior architects, tech leads, and software engineers working on the project.  Currently, I use the solution for my personal work.  The solution has good flexibility…

Delivers superior search and data aggregation capabilities
Neo4j helps with advanced search needs, providing good search results and aggregates compared to MongoDB. Aggregating with MongoDB can be difficult; however, with Neo4j, it's easier. Aggregating data, backing up, and creating new clusters are user-friendly from the back end. In DevOps web deployment, we noticed no database issues. We created Docker instances and set them up efficiently, managing databases up to 50 gigabytes.

Quotes from Members

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

Pros

"The solution has good flexibility and very fast performance for searching data."
"It can handle a lot of files quickly."
"We've found the product to be scalable."
"We decided to work with MongoDB as its interface is easier to understand and more universal."
"The most valuable features of MongoDB include the flexible schema for storing data, its replication capabilities with high availability through a replica set setup, and horizontal scalability using sharding."
"like its performance and the stability. It's very stable and, performance-wise, it's really great."
"The most valuable feature is the geometric information done with GeoJSON."
"It is convenient to use because we can do manipulations with the JSON data that we get. There are also a lot of joins and associations with MongoDB, which makes it easy to use for us."
"The solution's best feature is how it differs from traditional SQL databases. It's hard to map people and find those near me in SQL, which requires long, complex queries. Neo4j Graph Database makes this easier with simpler queries. It also supports more data types, like JSON, which SQL doesn't."
"For now, the tool doesn't break down or stop, so it is quite stable."
"It is good for search-based tasks, providing solid search results and aggregate results."
"Enables people to understand what the business problem is and how the technology helps."
"Creates the ability to visualize outputs."
"As a graph database, I am surprised at their performance and response time."
 

Cons

"There should be better integration with other databases."
"There is a need for improvement in MongoDB's customer support."
"Simplifying the aggregation framework would be an improvement."
"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."
"I'd like to see an ID generator. It's very technical but I don't think it has one, so we have to go to great lengths to work around that."
"The free tools, like MongoDB Compass, could be enhanced."
"There can be stability issues."
"There are some problems with bugs appearing in sharding when the data is too high."
"The tool could improve by having more resources, especially for Golang, which we use. It lacks good basic libraries and doesn't have an ORM (Object-Relational Mapping) tool, which many NoSQL databases have. We thought about building an ORM for the Neo4j Graph Database but are too busy."
"The only problem is that the community is quite small."
"For me, when the tool was deployed on an on-premises model, it was a little bit difficult the first time."
"There are concerns about performance and whether the tool can necessarily scale to provide the solution."
"So far, we have not had any issues and are happy with the product in general."
 

Pricing and Cost Advice

"It's open-source."
"MongoDB is not expensive."
"I chose MongoDB because it is cost-effective compared to Oracle, which can be expensive. In addition, MongoDB has good performance and has not caused any issues while working with it. It has been a good choice for me."
"MongoDB is a free solution. We wanted to have high availability and the subscription cost was quite expensive because the basic one is free and then when you want to have some other replications or other features you will need to pay money. Overall the solution is expensive."
"MongoDB's pricing is reasonable."
"You only have to pay for the paid version, not the open-source version."
"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 not reasonable, but it is not as expensive as the others."
"The solution is open source so that you can use it for free. They also offer an enterprise version with its billing. If your company is earning well, I suggest using the enterprise version. Otherwise, you can deploy it on your own cloud and pay based on usage."
"The tool is not expensive."
