Title CS2 Data Structures Activity
Overview Using the HFOSS OpenMRS project to illustrate the use of data structures in a complex system
Prerequisite Knowledge CS1 and Java
Learning Objectives
  1. Describe the difference between a data structure and the implementation thereof.
  2. Explain the application of a data structure in a specific large complex software system.
  3. Evaluate tradeoffs in selection of data structures.
  4. Analyze the time complexity of an algorithm that uses the data structure.


Data structures are widely used in the development of large complex software systems. The decision to use a particular data structure is made by the programmer or in many cases a development team. Several factors must be considered including storage requirements, time requirements of the various operations that will be performed on the data, and usage patterns (i.e. the number of deletions, insertions, updates, etc.).

This activity will explore a class within the OpenMRS code base where a number of data structures are utilized. As such, it is expected that the students will have some general knowledge about the OpenMRS project.
