Transforms data flow with adaptable schema and smooth public cloud deployment
One of our business units uses MongoDB, and we developed an ETL pipeline that extracts data from MongoDB and transfers it into our data warehouse MongoDB is a NoSQL database that is similar to a document database. It offers flexibility in schema adaptation, allowing us to change the schema and…

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 most valuable feature is that you can store unstructured data, which is helpful when you don't know what the best structure should be and you cannot use a relational database because of that."
"The solution's most important aspect is its seamless database."
"The initial setup isn't really that complex."
"The Dynamic Application is a valuable feature."
"It is very easy to create a MongoDB cluster. You can deploy three nodes in one hour. You can do small configurations to enable routing. It is easy to implement."
"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."
"Sharding is an excellent feature of MongoDB."
"The solution does not hold data in tabular format like SQL does but rather clusters data so that it can link on a large scale."
"As a graph database, I am surprised at their performance and response time."
"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."
"Enables people to understand what the business problem is and how the technology helps."
"It is good for search-based tasks, providing solid search results and aggregate results."
"For now, the tool doesn't break down or stop, so it is quite stable."
"Creates the ability to visualize outputs."
 

Cons

"I suppose it could be a little more secure."
"It is important to note that MongoDB has limitations since it can only be used for specific use cases. For example, for master data, I would want to pick keys using an RDBMS, but for attachments, I would choose MongoDB."
"The solution could include more integrations with other platforms."
"People coming from RDBMS should have the flexibility to write queries in SQL that can be converted into JSON queries."
"There are some problems with bugs appearing in sharding when the data is too high."
"The improvements could be made to intelligence to detect disk storage and prevent MongoDB from crashing."
"MongoDB could be more secure."
"The analytics needs improvement."
"The only problem is that the community is quite small."
"So far, we have not had any issues and are happy with the product in general."
"There are concerns about performance and whether the tool can necessarily scale to provide the solution."
"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."
"For me, when the tool was deployed on an on-premises model, it was a little bit difficult the first time."
 

Pricing and Cost Advice

"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."
"I don't know, but I have heard from people who procure it that it is much cheaper than Oracle."
"The solution is open source so is free."
"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."
"There are different licenses available to be purchased, such as individual, premium, or enterprise."
"This is an open-source solution."
"If you want support with the solution you will need to purchase a license and not use the open-source version. The license is a little expensive."
"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."
