A few words about PostgreSQL
PostgreSQL is an example of an advanced open source database system that has been complementing SQL (Structured Query Language) for more than 35 years. This cooperation makes both technologies capable of storing and scaling demanding yet complex data workloads at the same time. PostgreSQL is used in the development of Railwaymen projects because of its architecture, integrity, and extensive feature set. With the help of this database system, we are able to develop projects at the highest level.
Benefits of Using PostgreSQL
Multiplicity of functions
An undeniable benefit of using PostgreSQL is access to a sizable number of functions whose role is to support developers in the application development process. These functions are responsible for supporting the creation of the project and ensuring that it is free of any failures. The multitude of functions makes it possible for application developers to meet even the most complex requirements.
Support for standards
PostgreSQL offers compatibility with many SQL standards, which is a valuable addition to this database management system. This cooperation allows you to move applications between different database systems. In addition, using the software you can experience the option to define your own data types, indexes, aggregating functions, etc., which allow you to perform many types of complex operations.
Open source software
The software in question belongs to the open source type. This means that its source code is publicly available. This gives everyone the right to freely use and distribute it according to their own needs and without any licensing costs. The open source nature also means that the software is constantly being developed by many companies and individual users.
Security issues
PostgreSQL comes with high-quality access control mechanisms, with which any administrator can manage the necessary user permissions to the data and operations contained in the database. In addition, the software supports authentication protocols using passwords, certificates and authentication tied directly to the operating system. The level of security is also increased by the option to encrypt data collected in the database. This is an additional option that protects against unauthorized access.
Community and support
A feature that speaks for using PostgreSQL is the community, which is a huge support for anyone looking for any kind of guidance on the web. Specialists dedicated to the software unite on many channels to help find the right solutions. In addition, they are constantly developing knowledge resources, so that the experience they have gained translates into comfortable use of PostgreSQL capabilities.
Replication and scalability
There are various replication mechanisms in PostgreSQL. Among them are synchronous and asynchronous replication, which are responsible for maintaining copies of data for greater system availability and vertical scalability. Worth mentioning is table partitioning, which is responsible for efficient management of large data sets and better use of hardware resources.
ACID compatibility
PostgreSQL features ACID compliance. This is an acronym derived from the words Atomicity, Consistency, Isolation, Durability and stands for the guarantee of data reliability and integrity in the event of a system failure or other inconvenience. This is a very important aspect from the perspective of applications with high security and reliability requirements.
Why you should consider using PostgreSQL capabilities
When choosing an open source database, it is worth betting on a solution characterized by its reliability and the capabilities it has at its disposal. PostgreSQL is a good choice for developers of modern applications due to the capabilities it provides to each user. Scalability, security, stability, performance are just a few of the many synonyms that define this noteworthy software. It is also an interesting proposition from the perspective of developers, as the active community around PostgreSQL provides an attractive motivation to take advantage of the capabilities of this 30+ year old solution.
Which projects is PostgreSQL suitable for?
Due to its versatility, PostgreSQL software will be the right choice for both small, medium and large applications. Whether you are going to develop a web application or a mobile application, in both cases it will be a perfect complement to other technologies. Especially in terms of data storage, which for both web platforms and mobile applications based on iOS and Android operating systems is extremely important. PostgreSQL can also be used in the development of CMS, analytics applications, online games, as well as IoT solutions. It is up to the development team how much they want to explore its potential.

What are the prices of PostgreSQL services at Railwaymen?
Depending on the size of the project, the level of experience required and other factors, the price of PostgreSQL services can vary. Some service providers may offer a fixed price for the entire project, while others may charge an hourly rate. It’s important to discuss pricing and payment terms with service providers before starting work. At Railwaymen, the price for PostgreSQL services is determined based on prior meetings with the client, where the scope of the project and the details of its implementation are determined. Having a full set of information, we are able to estimate the exact costs of application development.
Depending on the customer's needs, we have two types of payments:

Tore Andreas Hansen & Torstein Floden,
CostTracker Founders
After speaking with several development agencies, we retained Railwaymen to turn our raw idea into first a clickable prototype for which we could obtain customer feedback, and second, into functioning software. They handled 100% of the design and development.
Railwaymen is a first class, high-quality operation which charges reasonable rates and does great work. We are extremely happy with the relationship, and plan to stay with Railwaymen through future versions of the software. Creative design and problem-solving have had the biggest impact on my impression. But the unwavering support and patience of their team is a close second.
