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…

Offers simplicity and is cheaply priced
I haven't gone through the scalability aspect since I was using MySQL Server. I haven't worked to a high level in PostgreSQL, but with MySQL Server, I have managed clustering and partitioning. I think I haven't put much focus on PostgreSQL, so I am not sure how it behaves or how it works.

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."
"MongoDB is easy to use."
"The most valuable feature is the geometric information done with GeoJSON."
"It's super easy to develop a couple of solutions for clients with MongoDB, like a quick web page with no clear data structure that they need to spin up quickly to validate some sort of MDTP."
"The aggregation framework is really good, allowing a developer to build very complex queries."
"MongoDB is flexible and it allows other applications to be added."
"Scalability seems good. I've never been even close to finding the limits. I've run a couple of notes of redundancy but I've never had any problems with scalability."
"It is really a pretty easy product to use. It's very reliable, it's proven."
"The initial setup is quick and easy."
"The most valuable features are the price, stability, it is scalable and is used by our clients in small business environments, and it is a simple product to use."
"The product is quite flexible."
"Postgres is rock solid when deployed according to best practices as documented by the PostgreSQL community. When it's installed correctly, PostgreSQL is an enterprise-grade solution."
"Postgres has some functions called JSONB aggregators or other aggregators, which are quite useful."
"I like that you can move any relational database from Oracle to PostgreSQL. I also like that it's pretty stable."
"PostgreSQL has complete SQL dialects and is useful for writing sophisticated and complex queries. We have experience with Oracle database. My partner is experienced in DDA and he writes sophisticated SQL queries. The solution helps to get the job done in the best possible way. In today’s age, most developers do not have strong SQL knowledge or language command. They find it difficult to write even a SQL statement. These developers write cool queries which perform badly on the database end. As DBAs, we constantly urge the developers not to write bad queries, help them learn more, and write placebo commands."
"Initial setup is simple."
 

Cons

"We'd like information about client onboarding experience and success stories. It would help to have something to show to internal stakeholders."
"Actually, with MongoDB, it's difficult to calculate the return on investment; it's too expensive for our use."
"The performance can be improved."
"I would like to see the scalability and security improved."
"People coming from RDBMS should have the flexibility to write queries in SQL that can be converted into JSON queries."
"MongoDB is a very useful and convenient choice, but sometimes for more complex projects, there are certain niche requirements that appear, so using a different tool could be beneficial. It raises the complexity of the architecture, but it could be beneficial to the world, the features, the ease of the features which are being implemented."
"The product's data consistency could be more efficient than traditional SQLs."
"The solution should more easily integrate with custom code."
"We have to set up event API, which takes a lot of events from the user."
"It would be great if the solution offered even more integration capabilities."
"It would be good to have machine learning functionality in this solution, similar to Microsoft SQL Server and other solutions. Machine learning capability for a basic level or a common user would be useful. It can also have good reporting capabilities."
"Sometimes, it becomes slow because of the network. So, there is room for improvement in performance."
"I don't think PostgreSQL supports bulk databases, so it needs to have more capabilities in terms of managing the bulk data."
"I have noticed that user and access management should be improved."
"PostgreSQL uses high memory compared to its counterparts when a highly demanding load is involved, especially one that makes many concurrent connections to the database."
"If it was free to use, it would be the perfect solution."
 

Pricing and Cost Advice

"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."
"It's a community edition, so we do not pay anything."
"MongoDB's pricing is not reasonable, but it is not as expensive as the others."
"I believe that the licensing fees are paid on a yearly basis."
"The solution is open source, so it is free."
"This 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."
"Our customers pay for yearly licenses for MongoDB."
"It is free. In terms of operating costs, it basically needs the same platform on which Oracle runs."
"PostgreSQL is a free and open-source database."
"It could be much cheaper. If you would like to build an application on Amazon today, PostgreSQL is the standard database with Redshift. If you want other databases, you can add them, but PostgreSQL is the basis of everything. It's a question of money, that's it."
"The tool is cheaply priced compared to other RDBMS providers in the market."
"Our company pays for it. There are free versions available, but for advanced features, you obviously have to pay."
"The need for our customers to pay for licences is contingent on their projects and budgets."
"It is open source. There is no licensing."
"It is also open-source so it is free."

It's a transactional database, so we use Postgres for most of our reporting. That's where it's helping.
