How to add FHIR module into the OpenMRS Platform?

What is OpenMRS?

A few decades back,  all the medical reports of patients were recorded as paper records. It could not be easy to manage and had to spend more time when working on them. When modern technology came, Health Care Applications were created and used to effectively record and manage patient medical records. Some of the Health Care applications are created as free and open source applications. OpenMRS is one of the open-source EMR tools that have been developed and implemented since 2004. It is used by healthcare workers over 5,500 health facilities around the world including 169 countries.

What is FHIR?

FHIR is the abbreviation for Fast Healthcare Interoperability Resources. It provides a standard to exchange electronic healthcare records by defining data formats and resources. 

What is WSO2 ESB?

What is ESB?

It removes the point-to-point integration and integrates numerous applications together over a bus-like infrastructure. It will handle transforming and routing the messages according to their appropriate destinations.

Getting Started with Maven

Since Ant, Maven, and Gradle are dominated in the JVM ecosystem as  Java build automation tools, you may be familiar with Maven If you have ever worked on a Java Project.

Let’s explore how these Java build automation tools evolved in the JVM ecosystem.

• Apache Ant (“Another Neat Tool”) is a Java library which is used to automate the build processes for Java applications. Other than that it can be used for building non-Java applications.
• Apache Maven is a build automation tool and also a dependency management tool. It is primarily used for Java applications. Maven also uses XML files the same as Apache Ant but in a much more manageable way.
• Gradle is a dependency management and a build automation tool which was built upon the concepts of Ant and Maven.

In this article, I am going to discuss Maven as a dependency management tool.
