Uzair Faruqi - PeerSpot reviewer
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

"In our case, it is most important to have redundancy."
"MongoDB has many good replication features and good performance."
"MongoDB is relatively fast compared to relational databases."
"I like that MongoDB has a free version. You can also buy the enterprise edition, which is cheaper than Oracle."
"Migrating to MongoDB upgrades the IT environment and puts users in the NoSQL environment, which is faster."
"It is really a pretty easy product to use. It's very reliable, it's proven."
"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."
"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."
"The product's deployment is easy."
"The solution is quite stable."
"I like that you can move any relational database from Oracle to PostgreSQL. I also like that it's pretty stable."
"We often use PostgreSQL for operations monitoring because we are a manufacturing company."
"The tool is user-friendly."
"The solution has many valuable features such as it easy to use and the interface is intuitive."
"Clustering will be the number 1 feature. It is also open-source so it is free. It can also be clustered, to allow fault tolerance."
"The PostgreSQL database is similar to the SQL Server but has a slightly different technology that has similar resources as well. If the customer has the confidence using SQL Server, they will be fairly comfortable using this solution."
 

Cons

"The scalability of the product is acceptable, but with MongoDB, the big problem is the cost."
"The performance of the solution could be improved."
"I think that MongoDB's search engine should be improved."
"I don't see a lot of areas that need improvement."
"MongoDB could be more secure."
"A normal Oracle or database tester will take some time to gear up to MongoDB because the way of writing queries is different in MongoDB. There should be some kind of midway where a person who is coming from an Oracle background can write a query and get a response by using something like a select * statement or other such things. There should be some way for MongoDB to interpret these commands rather than making a person learn MongoDB commands and writing them. I struggled while writing these MongoDB commands. I had not seen such queries before. It was pretty difficult to get them. This is one of the areas where it would help from the improvement standpoint."
"It would help if MongoDB offered a light solution for small projects."
"There is a need for improvement in MongoDB's customer support."
"The pricing could be better."
"PostgreSQL’s performance could be improved."
"I find it difficult to get connectors on the tool. For example, .NET has only one free provider in PostgreSQL. I need to pay the provider if I need something more sophisticated features. Other languages like PHP and Java have good community support. We need community support for .NET."
"PostgreSQL could improve by being more user-friendly. In SQL Server they have a studio where you can easily do management but not in this solution."
"PostgreSQL is a stable system, but from a security point of view, it still needs improvement."
"There could be a plugin to distribute the data on servers for the product."
"There are some products out there that have a slightly different method of implementation for the SQL language. Some of those are slightly better in some areas, and PostgreSQL is slightly better in some areas. I would probably like to match all of those products together. It is just down to the functionality. For example, Oracle has a number of options within SQL that are outside of what you would class as the SQL standard. PostgreSQL misses some of those, but PostgreSQL does other things that are better than what Oracle does. I would like to merge those two products so that there is a certain amount of functionality in a single product."
"The solution needs to improve the query, documentation, and JSON data functionality."
 

Pricing and Cost Advice

"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."
"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."
"MongoDB is an open-source solution."
"I'm using the free version of MongoDB."
"The solution is open source so is free."
"There is an annual subscription for the use of this solution."
"The product is affordable."
"This solution can offer a cheaper choice for customers since it is open-source."
"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."
"Our company pays for it. There are free versions available, but for advanced features, you obviously have to pay."
"The tool is cheaply priced compared to other RDBMS providers in the market."
"The community version of Postgre is basically free."
"It is free. There is no license on it."
"We use the open-source version of PostgreSQL and not the enterprise edition."
"It is also open-source so it is free."
