We are working with Spring Boot and everything related to this area, using a couple of modules from Spring Boot such as security, data, and cloud. The most major aspect is that we work with relational database architecture.

For the relational database, I use PostgreSQL on Ubuntu.

I have been using PostgreSQL on Ubuntu for all my commercial experience, which is around six or seven years.

I use a relational database where objects and relations between them are needed, and where there is a specific structure. For example, if we have a parameter for our object, such as a user or an apple, we have specific size, weight, etc. Non-relational database is not about that; it's more about speed, but relational databases are specifically created for this task.

The support for complex data types such as JSON and XML in PostgreSQL on Ubuntu adds technical behavior not related to typical relational databases. I have worked with JSON in PostgreSQL on Ubuntu, and it helps manage non-structured data effectively. You can also add an index for JSON and speed up searches, though it's a complex topic that requires deep knowledge of how indexes work.

The best feature of PostgreSQL on Ubuntu is its structure because it adds clarity and understanding when investigating a database. This structure makes it more understandable than non-structural data, which enhances readability and understandability for someone new to the project.

I have utilized the advanced data replication features in PostgreSQL on Ubuntu. It provides a powerful mechanism for transactions, which is a huge achievement for relational databases.

The community around PostgreSQL on Ubuntu is awesome and perfect. Any question or issue can be resolved with quick Googling, and there are many knowledgeable people, which is really beneficial.

Asynchronous replication will help in managing data distribution and seeing benefits, but I'm not certain as I have not worked with such tasks in PostgreSQL on Ubuntu. I've resolved similar things in non-SQL databases such as MongoDB, but I haven't attempted those functionalities in PostgreSQL on Ubuntu due to their complexity.

I have been using PostgreSQL on Ubuntu for all my commercial experience, which is around six or seven years.

The main benefits PostgreSQL on Ubuntu brings are stability and reliability, especially for transactions in companies handling money, which is crucial.

The main disadvantages I see in PostgreSQL on Ubuntu relate to handling scaling. Vertical scale can work sometimes, but as databases grow, resources can become inadequate, leading to the need for complex replication and sharding which not every specialist is aware of.

I have worked with other relational databases apart from PostgreSQL on Ubuntu.

In the very beginning of my learning path, I faced some difficulties in setting up PostgreSQL on Ubuntu, but now it's clear how it works. I know all the steps to make it work: creating databases, making users, providing rules, and creating tables.

The main differences of PostgreSQL on Ubuntu in comparison to other competitors involve ACID compliance, where non-relational databases have made strides. However, non-relational databases often have sharding available by default, making them more comfortable for dividing information. They also tend to be faster and fit for blob storage, but it's not the best way for storing files, as I prefer dedicated storage solutions such as S3 or Azure Blob Storage.

My advice for organizations considering PostgreSQL on Ubuntu is to thoroughly discuss their project needs, as it depends on their specific requirements. Spending time discussing future goals and project needs is crucial before making any decisions about a database, because changing databases during a project can be difficult and resource-intensive.

The structure and design of the database as it stands are really nice.

I haven't escalated any questions or issues regarding technical support with PostgreSQL on Ubuntu.

I don't remember anything about PostGIS capabilities.

On a scale of 1-10, I rate PostgreSQL on Ubuntu a 7.
