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.
Prerequisite Knowledge Design and architecture
Learning Objectives
  • To identify the architectural pattern used for a given system
  • To get exposed to web applications by studying their architectures
  • To differentiate between server side technologies and client side technologies
  • To use software architecture as a starting point to approach an open source project

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
