Software Engineer

It is an impressive open source software, really reliable. I love its PostGIS spatial module, which enables powerful geospatial functions.

Fixed Income Operations Specialist

After switching over from Access, it has been nice to be able to have a more robust experience.

Computer Science Student

It's a great relational database management system. It's open-source, free, reliable and secure.

Developer

It's a great tool and perfect value for money, since it's completely free. Perfect for small and medium sized applications.

Quality Engineer

It also has a perfect UI environment i.e. Pg Admin to run and save your SQL commands. It has a wonderful support page and can be integrated with any language.

Software developer

Probably because of bad stats but from time to time the problem happens again.

Software engineer

Best DBMS that I've used so far. Ability of saving data as objects and being a relational database management system make it most suitable for micro service architecture based developments.

IT Manager

The ease of use is a plus but I haven't dug deep into it yet as it's a test base for us right now. I like that it runs on linux and windows platforms, good support for JSON.

Quality Lead

Community support is superb: When ever you are stuck, you can ask the community, they will help you.

Freelancer

Overall the experience with PostgreSQL is pretty good. I have been using it continuously with different web development projects with the Django web development framework.

Owner

PostgreSQL is good for larger projects as it is relatively quick and easy to set up.

Consultant

Lot of features are missing from it as compared to the other products in the market.

It's the best open source relational database available. It's a full featured database, easy to use and integrate to you software.

Student

I had skipped the few initial classes and missed the part where the professor taught how to use the app.

Head of Engineering

Easy to use and scalable Open Source Database. Good indexing and search features, plus with json support you can easily make tables extendable and adaptable without schema changes.

Senior Software Engineer

Postgres provides poor support for identifying the queries that are running really slowly. E.g. you have to install a buggy plugin and then query a funky poorly documented table.

Java Developer

Thus, you can benefit from many features without paying any fees. It also has a very large community network.

PostgreSQL is one of the most feature-rich, powerful and advanced open-source database management systems. Though this power comes at a cost.

IBM Db2

DB2 DBA

I have worked with DB2 as a database manager for over 30 years. It is a great product, robust, lots of flexibility, ever improving and rock solid.

Senior Consultant

The bad thing that I see, is that you have to acquire a business license to use your maximum potential, apart from that there is also use IBM hardware, otherwise many conflicts are created.

We used it for projects that have a huge database and complex queries, the experience was great as the ability to handle complex queries reduced the load on our application.

Installation is very easy and when installed it's ease of use, very convenient. It's also very easy to connect to other tools like DBVisualizer which gives another way of viewing the tables and info.

It is such a powerful tool that optimized requested works super fast.

DevOps Developer

IBM DB2 is the best and most powerful relational database management system.

Powerful cloud and local solution for large and reliable project.

Application Developer

I was able to run millions, sometimes billions of rows of data through and it handled it just fine. The included functions were very helpful in translating complex data structures.

IBM Db2 is very expensive to maintain compared to its competitors. Another issue for me is the lack of timely updates.

Executive Recruiter

I find the customer support of IBM Db2 the best product support team as whenever we have questions they just respond to them in the quickest way.

Administrator / dba

It was simple to install and by default comes as self managed. We also deploy this for hosting customer data and integration with net backup, ha solutions and job scheduling is industry standard.

Associate Professor

The product supports almost any front-end application that requires database. All the drivers are provided as you setup a connection to an application.

It's fairly easy to set up and offers a lot of functionality, it's very easy to connect to most of the UI tools and framework. The security features make it ideal for banking applications.

I felt there is a storage capacity problem which sometimes makes it difficult to check the effectiveness of the entire database.

It did everything I needed. Maybe the only complaint would be how complex it is, but that is more of a feature not a bug.

Software Trainee

We don't have to worry about license costs as they wouldn't be more than that in Oracle. It can run on any OS like windows, Linux, Mac.

Error Handling feature is really impressive. DB2 provides API support for many languages.

Lead Data Analyst

We load all the sales data into DB2 system and will derive analytics on top of it. I can recommand if you have lot of budget to put on database managemnet.
