MongoDB is an open source document-oriented database system. It is part of the NoSQL family of database systems. Instead of storing data in tables as is done in a "classical" relational database, MongoDB stores structured data as JSON-like documents with dynamic schemas (MongoDB calls the format BSON), making the integration of data in certain types of applications easier and faster.

MongoDB is the primary db we use, and Meteor is the primary application framework. Configuring MongoDB to fully support Meteor oplog tailing is a challenge - and when we started looking, Compose was those only MongoDB provider that had turnkey support for Meteor.

Since we wanted …

We previously hosted our own Redis and RabbitMQ cluster. Before switching to IBM Compose we evaluated Redis Lab, Scalegrid, AWS ElastiCache, CloudAMQP and others. We still host our core database (MongoDB) ourselves.
Chose IBM Cloud Databases
When launching the system, using multiple services would have been inefficient, so we consolidated it on IBM Cloud Databases. We regularly compared the services provided by IBM Cloud Databases' PaaS with those of other cloud services, but decided that there was no need to go to …
Chose IBM Cloud Databases
All our databases are hosted on Compose. We haven't seen a reason to switch providers, however, we have compared with some others and Compose seems to be the best from a cost and reliability standpoint.
Chose IBM Cloud Databases
Compose has the best interface for viewing data. Others have better pricing. Atlas has best metrics.
Chose IBM Cloud Databases
It is pretty much the same only Compose offers many more database types.
Chose IBM Cloud Databases
We evaluated several DBaaS providers, the thing that won out for Compose was its GUI which makes working with the database very easy.
Chose IBM Cloud Databases
While at the time, Amazon RDS did/does not create Mongo databases, I was able to set up many with PostgreSQL databases with the same ease as IBM Compose. However, IBM compose does seem to offer a more intuitive application control panel. Amazon RDS costs run on a server …
Chose IBM Cloud Databases
We selected Compose because we initially thought that they would provide great support, and that they would bring encryption at rest within months. That has not materialized yet.

We also thought that the cost, while far from being the lowest, was reasonable.
Chose IBM Cloud Databases
Aiven backup options are very limited (you can't download backups and you don't have an API) and their dashboard is incomplete and without an optimal design; but they accept way more data centers, and they have more pricing options.
Chose IBM Cloud Databases
It was very easy to set up at the time with a few clicks to get a database set up and hooked into Heroku, one of the PaaS-s we're using.
Chose IBM Cloud Databases
We use Amazon Aurora as our primary datastore and use IBM Compose Mongo as an alternative only when Aurora does not cover the use case well. Amazon DynamoDB looks good but doesn't have the same wealth of libraries and support which makes MongoDB easy to use and therefore was …

Compose has great scalability and had a good price when we decided to launch our product.
Chose IBM Cloud Databases
Compose provides a lot more features for working with your database and its datasets
Chose IBM Cloud Databases
Other options are lower priced, however IBM Compose has by far the best interface for managing and editing data within the database. It also has many forms of databases for us to deploy, beyond what we are currently using. So, in the event we need to add other services, we can …
Chose IBM Cloud Databases
IBM Compose pricing is far more clear than Azure and Amazon. The web user interface is also very clear and simple.
Chose IBM Cloud Databases
We initially selected IBM Compose because it was easy to use and cost-effective. We switched to mLab when we need to scale and have dedicated clusters.
Chose IBM Cloud Databases
It feels very similar but Compose was there first. I haven't used MongoDB Atlas in anger yet but it does seem to be more comprehensive.
Chose IBM Cloud Databases
We currently use both Heroku and Compose. Heroku is our PAAS choice for our application servers. As mentioned, previously, the cost of some compose services for development / staging / testing servers was getting costly. For these type of servers we don't need the high …
Chose IBM Cloud Databases
Mongo Atlas - at the moment it looks better. It has 3.6 (Compose stuck at 3.4). Lower pricing (it seems).
AWS Dynamo DB etc - I decided rather quickly not to use this, mostly for lack of adequate documentation.

MongoDB is the most reliable and fastest for storing document-based data. It has a place among the most popular DB's these days.
Chose MongoDB
Both Couchbase and MongoDB are document-oriented NoSQL databases, so they have very similar features. While they do have some fundamental differences in terms of how they scale, shard, etc. the one key reason why we went with MongoDB is its availability and support from the …

We tend to choose MongoDB when we're faced with a particular situation: we know that we need a NoSQL database in general, and want an open-source implementation that allows us to prevent against platform lock-in. Amazon's new DocumentDB product even allows us to choose to use …
Chose MongoDB
MongoDB is the best NoSQL database out there. There are others, but Mongo has the largest community, is very easy to set up, and is extremely performant. Compared to a relational DB (like MySQL or Postgres) is like comparing apples and oranges. One isn't better or worse than …
Chose MongoDB
MongoDB is very easy to use and the best advantage is the NoSQL database. No concept of the relational database.

Chose MongoDB
I selected MongoDB because it works for well with web interfaces. All of the RDBMS alternatives would have required a lot more time writing schemas and working around retrieving data and mapping it. That could have been somewhat mitigated with Entity Framework, but that again …

The features between these database are quite comparable - except for possibly MongoDB. MongoDB being a different type of database and geared towards big data - I don't compare it to PostgreSQL. The other two I have used and would say PostgreSQL does fairly well when compared …

Despite being all open source options, what ended up making us choose PostgreSQL was the robustness of its core, which allows the great workflow that can support timely and efficient response to the demand and demand for resources. In the case of MongoDB, it is a non-relational …

Chose PostgreSQL
We selected PostgreSQL due to the number of employees who have used it in the past.
The data consistency guarantees.
The multiple transaction isolation levels support.
Chose PostgreSQL
PostgreSQL outperforms every other option. It is faster, more flexible, more reliable, easier to maintain, and more consistent in behaviour than any of the other offerings.
Chose PostgreSQL
It's a viable alternative, with a rich feature set and a reliable system. PostgreSQL is one of the best RDBMS's currently on the market in 2020, it serves just as well as a starter, PoC DB for any software idea as a final, highly valuable database solution for big systems.
Chose PostgreSQL
PostgreSQL is the proper tool when data consistency matters and other BASE or document-based databases are simply improper. I think PostgreSQL has a fantastic system of slony replication, triggers, and other data maintenance functionality that other databases generally don't …
Chose PostgreSQL
I found PostgreSQL to be better compared to MySQL. The community support is very good. Some features that I feel are not present in MySQL are:
  • No referential integrity.
  • No constraints (CHECK).
Chose PostgreSQL
Compared to MySQL, it works well if you need to extend to your use case
Compared to Spark, it works better w.r.t development time in a central database setting
Like Redis, it cannot be used for caching and quick access of non-structured data
Chose PostgreSQL
As I said, Postgres and MySQL are open source which is important for small start ups. Oracle is EXPENSIVE :)
Postgres is faster than MySQL (Big factor)
MySQL supports replication which makes it more scalable.

Less Appropriate Scenario: 1) Small Scale or Low Budget Projects 2) Organizations with limited expertise in cloud technologies may find the learning curve steep, especially if they are not familiar with the IBM Cloud platform 3) If database requirements are highly dynamic and change frequently, the comprehensive features and management provided by IBM Cloud Databases might be overkill. A more flexible, self-managed solution could be preferable for adapting to rapid changes.

If asked by a colleague I would highly recommend MongoDB. MongoDB provides incredible flexibility and is quick and easy to set up. It also provides extensive documentation which is very useful for someone new to the tool. Though I've used it for years and still referenced the docs often. From my experience and the use cases I've worked on, I'd suggest using it anywhere that needs a fast, efficient storage space for non-relational data. If a relational database is needed then another tool would be more apt.

PostgreSQL is best used for structured data, and best when following relational database design principles. I would not use PostgreSQL for large unstructured data such as video, images, sound files, xml documents, web-pages, especially if these files have their own highly variable, internal structure.

Pros
IBM
  • The ease of setup was effortless. For anyone with development experience, a few simple questions such as name and login data will get you set up.
  • The web application to manage cluster settings, billing settings and even introspect the data was simple and most importantly worked all the time. This can not always be said for web interfaces of other products.

  • Being a JSON language optimizes the response time of a query, you can directly build a query logic from the same service
  • You can install a local, database-based environment rather than the non-relational real-time bases such a firebase does not allow, the local environment is paramount since you can work without relying on the internet.
  • Forming collections in Mango is relatively simple, you do not need to know of query to work with it, since it has a simple graphic environment that allows you to manage databases for those who are not experts in console management.

  • It works well with external data sources and runs on platforms with stable performance.
  • Clients can rest assured that their personal information will be safe and secure.
  • Many forums discuss setup and usage, and most are free.
  • Adding tooling applications to a computer is unlimited.
  • PostgreSQL runs on many OS platforms and supports ANSI SQL, stored procedures, and triggers.

Cons
IBM
  • Better cost reports, before just increasing to another tier, thus increasing the price. This is critical for early stage startups, where budget is tight.
  • Add more data center options. As a comparison, a similar service, Aiven.io has dozen more options than Compose (basically all big cloud providers). We moved from AWS to Digital Ocean, which made us stop using Compose, since Compose forces us to be either on IBM or AWS.

  • An aggregate pipeline can be a bit overwhelming as a newcomer.
  • There's still no real concept of joins with references/foreign keys, although the aggregate framework has a feature that is close.
  • Database management/dev ops can still be time-consuming if rolling your own deployments. (Thankfully there are plenty of providers like Compose or even MongoDB's own Atlas that helps take care of the nitty-gritty.

  • Clearer indications on what is the query plan, to optimize the query

IBM Cloud Databases' pricing structure is easy to understand, and if you choose the right product, you can operate your system at minimal cost. Although there is ample documentation available, there doesn't seem to be a user community running on it, so specific usage know-how and troubleshooting can sometimes take longer than expected.

NoSQL database systems such as MongoDB lack graphical interfaces by default and therefore to improve usability it is necessary to install third-party applications to see more visually the schemas and stored documents. In addition, these tools also allow us to visualize the commands to be executed for each operation.

Postgresql is the best tool out there for relational data so I have to give it a high rating when it comes to analytics, data availability and consistency, so on and so forth. SQL is also a relatively consistent language so when it comes to building new tables and loading data in from the OLTP database, there are enough tools where we can perform ETL on a scalable basis.

Support is helpful enough, but we haven't always had questions answered in a satisfactory manner. At one time we realized that Compose had stopped taking database snapshots on its two-per-day schedule, and had in fact not taken one for many days. Support recognized the problem and it was fixed, but the lack of proactive checks and the inability to share exactly what happened has caused us to look elsewhere for production work loads

While the setup and configuration of MongoDB is pretty straight forward, having a vendor that performs automatic backups and scales the cluster automatically is very convenient. If you do not have a system administrator or DBA familiar with MongoDB on hand, it's a very good idea to use a 3rd party vendor that specializes in MongoDB hosting. The value is very well worth it over hosting it yourself since the cost is often reasonable among providers.

Although the competition between the different databases is increasingly aggressive in the sense that they provide many improvements, new functionalities, compatibility with complementary components or environments, in some cases it requires that it be followed within the same family of applications that performs the company that develops it and that is not all bad, but being able to adapt or configure different programs, applications or other environments developed by third parties apart is what gives PostgreSQL a certain advantage and this diversification in the components that can be joined with it, is the reason why it is a great option to choose.
