Title

OpenMRS Architecture case study

Overview

In this activity students use OpenMRS Architecture as a case study to identify the architecture pattern used and study the components of web architecture.

Prerequisites

Design and architecture

Learning
Objectives 		After successfully completing this activity, the learner should be able to:
  • Identify the architectural pattern used for a given system
  • Get exposed to web applications by studying their architectures
  • Differentiate between server side technologies and client side technologies
  • Use software architecture as a starting point to approach an open source project
Process Skills
Practiced


Background

Open-MRS is an open source electronic medical record system (EMR) originally designed for developing countries. Go the open MRS website https://wiki.openmrs.org/display/docs/Technical+Overview and http://write.flossmanuals.net/openmrs-developers-guide/architecture/ . The architectural design of the Open MRS system is described in these pages.

Directions

Study the architectural diagram and answer the following questions:

Part 1: General Architecture

  1. Identify the basic modules in the architecture. What are the basic components and how do they interact
  2. What architecture style is used in Open-MRS architecture? Justify your answer.

(Grading criteria: your answer should explain how the Open-MRS architecture satisfies the constraints and rules for the chosen architecture style)

Part 2: Server and client technologies

  1. What technologies are used on the client side?
  2. What technologies are used on the server-side?
  3. What is Spring? (use Google to answer. Include your reference)
  4. What is Hibernate? (use Google to answer. Include your reference)
  5. What language is used for server-side programming in OpenMRS?

Part 3: Design Principles

  1. OpenMRS architecture satisfies design principles such as modularity and information hiding. Explain how does the architecture satisfy these principles?
  2. Why does the architecture follow design principles ? (Find the answer in the reading)

Deliverable

  • A report including answers
